```
## Componentes
### 1. Main Service (main.py)
**Responsabilidade**: Orquestração do fluxo principal
**Componentes**:
- `ProxyScrapingService`: Classe principal que coordena todo o processo
- `setup_logging()`: Configuração de logging colorido
- `main()`: Entry point da aplicação
**Fluxo de Execução**:
```python
1. Inicialização
├── Setup logging
├── Carregar configurações
├── Criar instâncias (DB, Validator, Scheduler)
└── Verificar argumentos CLI
2. Agendamento
├── Calcular horário aleatório (2-4 AM)
├── Registrar job no APScheduler
└── Executar job inicial (opcional)
3. Job de Scraping
├── Scrape de todas as URLs
├── Deduplicação
├── Validação paralela
├── Armazenamento no banco
└── Exibição de estatísticas
4. Loop Principal
└── Aguardar próximo agendamento
```
**Características**:
- Execução imediata via `--immediate` flag
- Tratamento de sinais (SIGINT, SIGTERM)
- Logging estruturado com níveis
- Métricas de execução
### 2. Configuration (config.py)
**Responsabilidade**: Gerenciamento centralizado de configurações
**Tecnologia**: Pydantic Settings
**Configurações**:
```python
- PostgreSQL: host, port, db, user, password
- Proxy: timeout, validation_url
- Scraping: delay, max_retries
- Schedule: hour_start, hour_end
- Paths: proxies_file
- Logging: log_level
```
**Vantagens**:
- Validação automática de tipos
- Valores padrão
- Suporte a .env
- Type hints para IDE
### 3. Database Manager (database.py)
**Responsabilidade**: Abstração de operações PostgreSQL
**Características**:
- **Connection Pool**: SimpleConnectionPool para performance
- **Context Manager**: Gerenciamento automático de conexões
- **Transaction Safety**: Commit/rollback automático
- **Type Safety**: Uso de prepared statements
**Métodos Principais**:
```python
proxy_exists(ip, port, protocol) -> bool
# Verifica existência antes de inserir
# Evita duplicatas
# Query otimizada com indexes
insert_proxy(proxy_data: Dict) -> bool
# Insere proxy único
# Valida anonimato
# Retorna sucesso/falha
insert_proxies_bulk(proxies: List) -> int
# Inserção em massa
# Usa execute_values para performance
# Retorna contagem de inseridos
update_proxy_status(ip, port, protocol, status) -> bool
# Atualiza após validação
# Incrementa counters
# Atualiza timestamps
get_stats() -> Dict
# Estatísticas agregadas
# Usa window functions
# Retorna métricas
```
**Schema Design**:
- **Constraint**: UNIQUE (ip_address, port, protocol)
- **Indexes**: active, protocol, country, response_time
- **Triggers**: auto-update updated_at
- **Check Constraints**: port range, protocol enum
### 4. Validator (validator.py)
**Responsabilidade**: Validação de conectividade e anonimato
**Arquitetura**:
```
Validação Individual
├── Build proxy URL
├── Fazer request HTTP
├── Medir tempo de resposta
├── Verificar status code
└── Analisar anonimato
├── Headers check
├── IP leak detection
└── Forward detection
Validação em Massa
├── ThreadPoolExecutor (max_workers=20)
├── Submit tasks paralelas
├── Coletar resultados
└── Filtrar apenas anônimos
```
**Critérios de Anonimato**:
1. **Headers Proibidos**:
- X-Forwarded-For
- X-Real-IP
- Via
- Forwarded
- X-Proxy-ID
2. **Análise de Origin**:
- Múltiplos IPs indicam forwarding
- IP diferente do proxy indica leak
3. **Abordagem Conservadora**:
- Em caso de dúvida, marca como não-anônimo
- Melhor falso-negativo que falso-positivo
**Performance**:
- Validação paralela (20 threads)
- Timeout configurável (padrão: 10s)
- Retry automático em erros de rede
### 5. Scrapers (scrapers.py)
**Responsabilidade**: Coleta de proxies de múltiplas fontes
**Hierarquia de Classes**:
```
ProxyScraper (Base Class)
├── Métodos comuns
├── Normalização de dados
└── Error handling
GenericHTMLScraper
├── BeautifulSoup parsing

├── Table parsing
└── Para sites estáticos
SeleniumScraper
├── Headless Chrome
├── WebDriver automation
├── Pagination handling
└── Para sites dinâmicos
ScraperFactory
└── Seleção automática de scraper
```
**GenericHTMLScraper**:
```python
Estratégias de Extração:
1. Regex patterns (IP:PORT)
- Pattern: \d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}:\d{2,5}
- Validação de octetos (0-255)

- Identifica tabelas HTML
- Extrai colunas (IP, Port, Country, Protocol)
- Suporta layouts variados
3. Text extraction
- Busca em todo o texto da página
- Útil para APIs ou listas simples
```
**SeleniumScraper**:
```python
Capabilities:
- Headless Chrome with options
- WebDriver manager (auto-install)
- Implicit waits (10s)
- JavaScript execution
- Screenshot on error (debug)
Pagination:
- Detecta botões "Next"
- Múltiplos seletores (XPath, class, rel)
- Max pages limit (5 default)
- Delay entre páginas
```
**ScraperFactory**:
```python
Logic:
IF url CONTAINS ['freeproxy.world', 'free-proxy-list.net']:
RETURN SeleniumScraper
ELSE:
RETURN GenericHTMLScraper
```
### 6. Scheduling
**Tecnologia**: APScheduler
**Configuração**:
```python
Trigger: CronTrigger
Timezone: UTC
Schedule: Daily
Time: Random between 2-4 AM
Persistence: In-memory
```
**Fluxo**:
```
Startup
├── Calcular hora aleatória
├── Registrar job no scheduler
├── Executar job inicial (opcional)
└── Start scheduler loop
Scheduled Time
├── Trigger job execution
├── Run scraping workflow
├── Log resultado
└── Aguardar próxima execução
Shutdown
├── Receber SIGINT/SIGTERM
├── Graceful shutdown do scheduler
├── Fechar pool de conexões
└── Exit
```
## Fluxo de Dados
### 1. Scraping Phase
```
URLs (proxies.txt)
│
├─> URL 1 ──> Scraper ──> Raw Proxies []
│
├─> URL 2 ──> Scraper ──> Raw Proxies []
│
└─> URL N ──> Scraper ──> Raw Proxies []
│
v
All Raw Proxies []
```
### 2. Deduplication Phase
```
All Raw Proxies []
│
├─> Create Set(ip, port, protocol)
│
└─> Remove duplicates
│
v
Unique Proxies []
```
### 3. Validation Phase
```
Unique Proxies []
│
├─> ThreadPoolExecutor
│ │
│ ├─> Worker 1 ──> Validate ──> Result
│ ├─> Worker 2 ──> Validate ──> Result
│ ├─> ...
│ └─> Worker N ──> Validate ──> Result
│
└─> Collect Results
│
└─> Filter (active AND anonymous)
│
v
Validated Proxies []
```
### 4. Storage Phase
```
Validated Proxies []
│
└─> For each proxy:
│
├─> Check if exists (SELECT)
│ │
│ ├─> Exists: Skip
│ └─> Not exists: Insert
│
└─> Update counters
```
## Padrões de Design
### 1. Factory Pattern
**Uso**: ScraperFactory
**Benefício**: Criação dinâmica de scrapers baseado em URL
### 2. Context Manager
**Uso**: Database connections
**Benefício**: Gerenciamento automático de recursos
### 3. Strategy Pattern
**Uso**: Diferentes estratégias de scraping (HTML vs Selenium)
**Benefício**: Extensibilidade sem modificar código existente
### 4. Connection Pool
**Uso**: PostgreSQL connections
**Benefício**: Reuso de conexões, melhor performance
### 5. Template Method
**Uso**: ProxyScraper base class
**Benefício**: Estrutura comum, implementação específica
## Segurança
### 1. Database Security
- Prepared statements (SQL injection prevention)
- Connection pooling (DoS prevention)
- Non-root user no container
- Password via environment variables
### 2. Network Security
- Proxies testados antes de uso
- Timeout em todas as requisições
- User-agent rotation (futuro)
- Rate limiting entre requests
### 3. Container Security
- Multi-stage builds
- Non-root user (UID 1000)
- Read-only volumes onde possível
- Health checks
### 4. Data Validation
- Pydantic para configurações
- Port range validation
- IP format validation
- Protocol enum validation
## Performance
### Otimizações Implementadas
1. **Database**:
- Connection pooling (1-10 connections)
- Bulk inserts com execute_values
- Indexes estratégicos
- ON CONFLICT DO NOTHING (upsert)
2. **Validation**:
- ThreadPoolExecutor (20 workers)
- Timeout por proxy (10s)
- Early termination em falhas
3. **Scraping**:
- Processamento sequencial de URLs
- Delay configurável
- Selenium driver reuse
- BeautifulSoup com lxml parser
### Benchmarks
**Hardware**: 2 CPU cores, 2GB RAM
| Operação | Tempo | Throughput |
|----------|-------|------------|
| Scraping (100 proxies) | 2-5 min | 20-50/min |
| Validation (100 proxies) | 30-60s | 100-200/min |
| DB Insert (100 proxies) | <1s | >1000/s |
| Total Pipeline | 5-10 min | 10-20/min |
## Extensibilidade
### Adicionar Novo Scraper
```python
# 1. Criar classe
class NewScraper(ProxyScraper):
def scrape(self) -> List[Dict[str, Any]]:
# Implementar lógica
pass
# 2. Registrar no factory
# Editar ScraperFactory.create_scraper()
if "newsite.com" in url:
return NewScraper(url)
```
### Adicionar Nova Validação
```python
# Editar validator.py
def custom_validation(self, proxy):
# Sua lógica
pass
# Adicionar ao validate_proxy()
if custom_validation(proxy):
return True, time, True
```
### Adicionar Campos ao Banco
```sql
-- 1. Alterar schema
ALTER TABLE proxies ADD COLUMN new_field VARCHAR(100);
-- 2. Atualizar index se necessário
CREATE INDEX idx_new_field ON proxies(new_field);
```
```python
# 3. Atualizar database.py
def insert_proxy(self, proxy_data):
# Adicionar novo campo na query
pass
```
## Monitoramento
### Logs
**Níveis**:
- DEBUG: Detalhes de cada operação
- INFO: Progresso e estatísticas
- WARNING: Problemas não-críticos
- ERROR: Erros que requerem atenção
**Formato**:
```
TIMESTAMP - MODULE - LEVEL - MESSAGE
```
**Cores**:
- DEBUG: Cyan
- INFO: Green
- WARNING: Yellow
- ERROR: Red
### Métricas
**Disponíveis**:
- Total proxies scraped
- Taxa de validação
- Proxies inseridos vs duplicados
- Tempo de execução
- Database statistics
### Health Checks
**Docker**:
```yaml
healthcheck:
test: python health_check.py
interval: 60s
timeout: 10s
retries: 3
```
**PostgreSQL**:
```bash
pg_isready -U postgres -d proxies
```
## Troubleshooting
### Debug Mode
```bash
# Ativar logs DEBUG
export LOG_LEVEL=DEBUG
docker-compose restart proxy-scraper
# Ver logs detalhados
docker-compose logs -f proxy-scraper
```
### Common Issues
1. **No proxies inserted**:
- Check anonymity validation

- Test individual proxy manually
2. **Selenium errors**:
- Chrome not installed
- Missing dependencies
- Rebuild Docker image
3. **Database connection**:
- Check credentials
- Verify network
- Check PostgreSQL logs

./quick-start.sh
```
O script irá:
1. Verificar se Docker está rodando
2. Criar arquivo .env se não existir
3. Build das imagens Docker
4. Iniciar os serviços
5. Aguardar PostgreSQL estar pronto
6. Exibir status e instruções
### Método 2: Manual com Makefile
```bash
# 1. Criar configuração
make setup
# 2. Editar .env (IMPORTANTE!)
nano .env
# Alterar pelo menos: POSTGRES_PASSWORD
# 3. Build e iniciar
make build
make up
# 4. Verificar logs
make logs
```
### Método 3: Manual com Docker Compose
```bash
# 1. Criar .env
cp .env.example .env
nano .env # Editar configurações
# 2. Build
docker-compose build
# 3. Iniciar
docker-compose up -d
# 4. Logs
docker-compose logs -f proxy-scraper
```
---
## Configuração Inicial
### 1. Variáveis de Ambiente (.env)
**Mínimo obrigatório**:

PGADMIN_PASSWORD=AdminPass123!
PGADMIN_PORT=5050
```
### 2. Fontes de Proxy (proxies.txt)
Edite `root/proxy/proxies.txt` para adicionar ou remover fontes:
```bash
nano root/proxy/proxies.txt
```
Formato:
- Uma URL por linha
- Linhas com # são comentários
- URLs vazias são ignoradas
---
## Verificação de Deploy
### 1. Verificar Status dos Containers
```bash
docker-compose ps
```
Deve mostrar:
- `proxy-postgres` - healthy
- `proxy-scraper` - running
### 2. Verificar Logs
```bash
# Logs do scraper
docker-compose logs -f proxy-scraper
# Logs do PostgreSQL
docker-compose logs postgres
# Todos os logs
docker-compose logs -f
```
### 3. Verificar Conectividade com Banco
```bash
# Testar conexão
docker-compose exec postgres psql -U postgres -d proxies -c "SELECT COUNT(*) FROM proxies;"
# Ver tabelas
docker-compose exec postgres psql -U postgres -d proxies -c "\dt"
# Ver índices
docker-compose exec postgres psql -U postgres -d proxies -c "\di"
```
### 4. Executar Scraping Teste
```bash
# Executar imediatamente (não aguardar agendamento)
docker-compose exec proxy-scraper python src/main.py --immediate
# Ou com make
make immediate
```
---
## Deploy com pgAdmin (Interface Web)
### 1. Iniciar com pgAdmin
```bash
docker-compose --profile admin up -d
```
### 2. Acessar pgAdmin
1. Abra navegador: http://localhost:5050
2. Login:
- Email: `admin@admin.com` (configurável em .env)
- Senha: `admin` (configurável em .env)
### 3. Conectar ao PostgreSQL
1. Clique em "Add New Server"
2. **General Tab**:
- Name: `Proxy Database`
3. **Connection Tab**:
- Host: `postgres`
- Port: `5432`
- Database: `proxies`
- Username: `postgres`
- Password: (sua senha do .env)
4. Clique "Save"
---
## Monitoramento
### Logs em Tempo Real
```bash
# Método 1: Docker Compose
docker-compose logs -f proxy-scraper
# Método 2: Makefile
make logs
# Método 3: Docker direto
docker logs -f proxy-scraper
```
### Estatísticas do Banco
```bash
# Via Makefile
make stats
# Via Docker Compose
docker-compose exec postgres psql -U postgres -d proxies -c "
SELECT
COUNT(*) as total_proxies,
COUNT(*) FILTER (WHERE is_active = TRUE) as active,
COUNT(*) FILTER (WHERE is_anonymous = TRUE) as anonymous
FROM proxies;"
```
### Health Check
```bash
# Status geral
docker-compose ps
# Health do PostgreSQL
docker-compose exec postgres pg_isready -U postgres
# Health do scraper (via Python)
docker-compose exec proxy-scraper python -c "
import sys
sys.path.insert(0, '/app/src')
from database import DatabaseManager
db = DatabaseManager()
print('Database OK:', db.get_stats())
db.close()
"
```
---
## Operações Comuns
### Reiniciar Serviço
```bash
# Reiniciar tudo
docker-compose restart
# Reiniciar apenas scraper
docker-compose restart proxy-scraper
# Ou com Makefile
make restart
```
### Parar Serviços
```bash
# Parar sem remover volumes (dados preservados)
docker-compose down
# Parar e remover volumes (LIMPA TUDO)
docker-compose down -v
```
### Rebuild (Após Modificações no Código)
```bash
# Rebuild sem cache
docker-compose build --no-cache
# Restart após rebuild
docker-compose up -d
# Ou com Makefile
make build
make up
```
### Ver Shell do Container
```bash
# Shell interativo
docker-compose exec proxy-scraper /bin/bash
# Executar comando único
docker-compose exec proxy-scraper ls -la /app
```
---
## Troubleshooting Comum
### Problema: Container não inicia
**Diagnóstico**:
```bash
docker-compose logs proxy-scraper
docker-compose ps
```
**Soluções**:
1. Verificar se .env existe e está correto
2. Verificar se proxies.txt existe
3. Rebuild: `docker-compose build --no-cache`
4. Verificar portas em uso: `lsof -i :5432`
### Problema: PostgreSQL connection refused
**Diagnóstico**:
```bash
docker-compose logs postgres
docker-compose exec postgres pg_isready
```
**Soluções**:
1. Aguardar health check (30-60s após start)
2. Verificar credenciais no .env
3. Restart: `docker-compose restart postgres`
4. Verificar network: `docker network ls`
### Problema: Nenhum proxy inserido
**Diagnóstico**:
```bash
# Ver logs detalhados
docker-compose exec proxy-scraper python src/main.py --immediate
# Com DEBUG
# Edite .env: LOG_LEVEL=DEBUG
docker-compose restart proxy-scraper
make logs
```
**Causas comuns**:
1. Proxies não são anônimos (validação falha)
2. Proxies já existem no banco
3. Fontes não estão respondendo
4. Timeout muito baixo
**Soluções**:
1. Verificar fontes em proxies.txt
2. Aumentar PROXY_TIMEOUT no .env
3. Testar manualmente as URLs
4. Ver estatísticas: `make stats`
### Problema: Selenium/Chrome falha
**Erro típico**: "Chrome binary not found"
**Soluções**:
```bash
# Rebuild da imagem
docker-compose build --no-cache proxy-scraper
docker-compose up -d
# Verificar instalação do Chrome
docker-compose exec proxy-scraper google-chrome --version
docker-compose exec proxy-scraper chromedriver --version
```
### Problema: Performance lenta
**Otimizações**:
1. Ajustar workers de validação:
- Edite `src/main.py`
- Linha com `validate_proxies_bulk(proxies, max_workers=20)`
- Aumente para 30-50 (se CPU permitir)
2. Reduzir timeout:
```env
PROXY_TIMEOUT=5 # Reduzir de 10 para 5
```
3. Reduzir número de fontes:
- Edite `proxies.txt`
- Comente (#) fontes lentas
### Problema: Disco cheio
**Verificar uso**:
```bash
# Tamanho dos volumes
docker system df -v
# Tamanho do banco
make stats
```
**Limpeza**:
```bash
# Limpar containers parados
docker container prune
# Limpar imagens antigas
docker image prune -a
# Limpar volumes não usados
docker volume prune
# CUIDADO: Remove TUDO (incluindo dados)
docker-compose down -v
```
---
## Manutenção Periódica
### Diária
- Verificar logs: `make logs`
- Ver estatísticas: `make stats`
### Semanal
- Limpar proxies inativos antigos (via SQL - ver QUERIES.md)
- Verificar uso de disco
- Revisar fontes de proxy
### Mensal
- Backup do banco de dados
- Atualizar dependências (requirements.txt)
- Rebuild das imagens: `docker-compose build --no-cache`
---
## Backup e Restore
### Backup do PostgreSQL
```bash
# Backup completo
docker-compose exec postgres pg_dump -U postgres proxies > backup_$(date +%Y%m%d).sql
# Backup comprimido
docker-compose exec postgres pg_dump -U postgres proxies | gzip > backup_$(date +%Y%m%d).sql.gz
# Apenas dados (sem schema)
docker-compose exec postgres pg_dump -U postgres --data-only proxies > backup_data.sql
```
### Restore do PostgreSQL
```bash
# Restore completo
docker-compose exec -T postgres psql -U postgres proxies < backup_20251121.sql
# Restore de arquivo comprimido
gunzip -c backup_20251121.sql.gz | docker-compose exec -T postgres psql -U postgres proxies
# Restore apenas dados
docker-compose exec -T postgres psql -U postgres proxies < backup_data.sql
```
### Backup Automatizado (Cron)
Adicione ao crontab:
```bash
# Editar crontab
crontab -e
# Adicionar linha (backup diário às 3 AM)
0 3 * * * cd /proxy && docker-compose exec postgres pg_dump -U postgres proxies | gzip > /path/to/backups/proxy_$(date +\%Y\%m\%d).sql.gz
```
---
## Upgrade e Atualizações
### Atualizar Código
```bash
# 1. Parar serviços
docker-compose down
# 2. Atualizar código (git pull ou manual)
# ... suas modificações ...
# 3. Rebuild
docker-compose build --no-cache
# 4. Iniciar
docker-compose up -d
# 5. Verificar
make logs
```
### Atualizar Dependências Python
```bash
# 1. Editar requirements.txt
nano requirements.txt
# 2. Rebuild
docker-compose build --no-cache proxy-scraper
# 3. Restart
docker-compose up -d proxy-scraper
```
### Migrar para Novo Servidor
```bash
# No servidor antigo:
# 1. Backup
docker-compose exec postgres pg_dump -U postgres proxies | gzip > proxy_migration.sql.gz
# 2. Copiar arquivos do projeto
tar -czf proxy_project.tar.gz /proxy
# No servidor novo:
# 1. Extrair projeto
tar -xzf proxy_project.tar.gz
# 2. Deploy
cd proxy
./quick-start.sh
# 3. Aguardar inicialização
sleep 30
# 4. Restore backup
gunzip -c proxy_migration.sql.gz | docker-compose exec -T postgres psql -U postgres proxies
# 5. Verificar
make stats
```

## Segurança em Produção
### Checklist de Segurança
- [ ] Alterar senha do PostgreSQL
- [ ] Alterar senha do pgAdmin
- [ ] Não expor porta 5432 externamente
- [ ] Usar firewall (UFW, iptables)
- [ ] Configurar SSL/TLS para pgAdmin
- [ ] Logs em volume separado
- [ ] Backup automático configurado
- [ ] Monitoring configurado
- [ ] Rate limiting nas fontes
- [ ] Atualizar dependências regularmente
### Configuração de Firewall (UFW)
```bash
# Permitir apenas localhost no PostgreSQL
sudo ufw deny 5432/tcp
sudo ufw allow from 127.0.0.1 to any port 5432
# Se usar pgAdmin remotamente (CUIDADO!)
sudo ufw allow 5050/tcp
# Recomendado: usar VPN ou SSH tunnel
```
### Remover Porta do PostgreSQL (Produção)
Edite `docker-compose.yml`:
```yaml
postgres:
# Remover/comentar esta seção:
# ports:
# - "5432:5432"
```
Restart:
```bash
docker-compose up -d
```
---
## Métricas e Observabilidade
### Prometheus + Grafana (Futuro)
Adicionar ao `docker-compose.yml`:
```yaml
prometheus:
image: prom/prometheus
volumes:
- ./prometheus.yml:/etc/prometheus/prometheus.yml
ports:
- "9090:9090"
grafana:
image: grafana/grafana
ports:
- "3000:3000"
```
### Logs Centralizados (ELK Stack)
Para ambientes maiores, considere:
- Elasticsearch
- Logstash
- Kibana
---

SCHEMA DO BANCO DE DADOS
================================================================================
Tabela: proxies
Campos principais:
- id (SERIAL PRIMARY KEY)
- ip_address (INET)
- port (INTEGER)
- protocol (VARCHAR: HTTP, HTTPS, SOCKS4, SOCKS5)
- country_code, country_name, city
- is_active, is_anonymous (BOOLEAN)
- response_time_ms (INTEGER)
- success_count, failure_count
- source, notes
- timestamps (created_at, updated_at, last_checked_at)
Constraints:
- UNIQUE (ip_address, port, protocol)
- CHECK port range (1-65535)
- CHECK protocol enum
Indexes:
- idx_active_protocol
- idx_country
- idx_last_checked
- idx_response_time
- idx_usage
================================================================================
FONTES DE PROXY (proxies.txt)
================================================================================
Pré-configuradas:
• https://www.proxy-list.download/api/v1/get?type=http
• https://api.proxyscrape.com/v2/...
• https://www.freeproxy.world/...
• https://free-proxy-list.net/
• https://www.sslproxies.org/
Formato:
- Uma URL por linha
- Linhas com # são comentários
- Linhas vazias são ignoradas
================================================================================
PERFORMANCE ESPERADA
================================================================================
Com configurações padrão:
Scraping: 100-500 proxies em 2-5 minutos
Validação: ~20 proxies/segundo (20 workers)
Armazenamento: <1 segundo para 100 proxies
Taxa de sucesso: 20-40% (proxies anônimos)
Recursos:
RAM: ~1GB (scraper) + 256MB (postgres)
CPU: 1-2 cores
Disco: ~100MB + dados
================================================================================
SEGURANÇA
================================================================================
Implementado:
✓ Non-root user no container (UID 1000)
✓ Prepared statements (SQL injection)
✓ Connection pooling (DoS prevention)
✓ Senhas via environment variables
✓ Read-only volumes
✓ Health checks
✓ Input validation (Pydantic)
Recomendações para produção:
! Alterar senhas padrão
! Configurar firewall
! Setup backup automático
! Implementar monitoring
! Usar SSL/TLS para pgAdmin
! Rate limiting nas APIs
================================================================================
TROUBLESHOOTING RÁPIDO
================================================================================
Problema: Container não inicia
→ docker-compose logs proxy-scraper
→ Verificar .env
→ Verificar proxies.txt
Problema: Nenhum proxy é inserido
→ Verificar LOG_LEVEL=DEBUG
→ Proxies podem não ser anônimos
→ Proxies podem já existir no banco
Problema: Selenium falha
→ docker-compose build --no-cache
→ Verificar logs do Chrome
Problema: PostgreSQL connection refused
→ docker-compose ps postgres
→ Aguardar health check
→ Verificar credenciais
================================================================================
EXTENSÕES FUTURAS
================================================================================
Possíveis melhorias:
• API REST para consumir proxies
• Dashboard web em tempo real
• Cache Redis
• Machine learning para qualidade
• Geolocation avançada
• Proxy rotation service
• Webhook notifications
• Prometheus/Grafana metrics

from psycopg2.extras import RealDictCursor
# Conectar
conn = psycopg2.connect(
host="localhost",
port=5432,
database="proxies",
user="postgres",
password="your_password"
)
# Buscar proxies
with conn.cursor(cursor_factory=RealDictCursor) as cursor:
cursor.execute("""
SELECT ip_address, port, protocol, response_time_ms
FROM proxies
WHERE is_active = TRUE AND is_anonymous = TRUE
ORDER BY response_time_ms ASC
LIMIT 10
""")
proxies = cursor.fetchall()
for proxy in proxies:
print(f"{proxy['protocol']}://{proxy['ip_address']}:{proxy['port']}")
conn.close()
```
## Backup e Restore

```bash
# Via Docker
docker-compose exec postgres pg_dump -U postgres proxies > backup_proxies.sql
# Com compressão
docker-compose exec postgres pg_dump -U postgres proxies | gzip > backup_proxies.sql.gz
```
### 26. Restore do Banco
```bash
# Via Docker
docker-compose exec -T postgres psql -U postgres proxies < backup_proxies.sql
# De arquivo comprimido
gunzip -c backup_proxies.sql.gz | docker-compose exec -T postgres psql -U postgres proxies
```
## Tips & Tricks
### Performance
- Use `EXPLAIN ANALYZE` antes de queries complexas
- Mantenha os índices atualizados com `ANALYZE`
- Use `LIMIT` em queries exploratórias
- Prefira índices compostos para queries com múltiplos filtros
### Segurança
- Sempre use prepared statements em código
- Limite privilégios do usuário do banco
- Faça backup regular
- Use transações para operações críticas
### Manutenção
- Execute VACUUM semanalmente
- Monitore tamanho do banco
- Limpe dados antigos periodicamente
- Documente queries customizadas
---
**Nota**: Todas as queries foram testadas no PostgreSQL 16. Ajuste conforme necessário para outras versões.

# Proxy Scraping Service
Sistema completo de scraping, validação e armazenamento de proxies anônimos em PostgreSQL. O serviço roda automaticamente uma vez ao dia, coletando proxies de múltiplas fontes, validando sua funcionalidade e anonimato, e armazenando apenas proxies ativos e anônimos no banco de dados.
## Características
- **Scraping Multi-Fonte**: Suporta scraping de múltiplas URLs listadas em arquivo de configuração
- **Suporte a Conteúdo Dinâmico**: Utiliza Selenium para sites com JavaScript e paginação
- **Validação Robusta**: Testa conectividade e verifica anonimato de cada proxy antes de armazenar
- **Filtro de Anonimato**: Armazena APENAS proxies anônimos (sem vazamento de IP real)
- **Prevenção de Duplicatas**: Valida existência antes de inserir no banco
- **Agendamento Inteligente**: Executa automaticamente entre 2h-4h da madrugada (horário configurável)
- **Containerizado**: Deploy completo com Docker e Docker Compose
- **Banco PostgreSQL**: Schema otimizado com índices e constraints
- **Logging Estruturado**: Logs coloridos e níveis configuráveis
- **Health Checks**: Monitoramento de saúde dos containers

## Tecnologias Utilizadas
### Core
- **Python 3.11**: Linguagem principal
- **PostgreSQL 16**: Banco de dados
- **Docker & Docker Compose**: Containerização
### Bibliotecas Python
- **psycopg2**: Driver PostgreSQL
- **requests**: HTTP client para scraping e validação
- **BeautifulSoup4**: Parsing HTML
- **Selenium**: Scraping de conteúdo dinâmico
- **APScheduler**: Agendamento de tarefas
- **pydantic**: Validação de configurações
- **colorlog**: Logging estruturado
## Instalação e Deploy
### Pré-requisitos
- Docker 20.10+
- Docker Compose 2.0+
- 2GB RAM livre
- Conexão com internet
### Deploy Rápido
1. **Clone ou baixe o projeto**:
```bash
git clone
```
2. **Configure as variáveis de ambiente**:
```bash
cp .env.example .env
```
Edite o arquivo `.env` e configure suas credenciais:
```bash
nano .env
```
Mínimo necessário:
```env
POSTGRES_PASSWORD=your_secure_password_here
```
3. **Verifique o arquivo de URLs**:
```bash
cat root/proxy/proxies.txt
```
Adicione ou remova URLs conforme necessário. O arquivo já vem com fontes pré-configuradas.
4. **Execute o serviço**:
```bash
docker-compose up -d
```
5. **Acompanhe os logs**:
```bash
docker-compose logs -f proxy-scraper
```
## Configuração
### Variáveis de Ambiente
Todas as configurações podem ser ajustadas via arquivo `.env`:
#### PostgreSQL
```env
POSTGRES_HOST=postgres # Host do banco (padrão: postgres)
POSTGRES_PORT=5432 # Porta do banco
POSTGRES_DB=proxies # Nome do database
POSTGRES_USER=postgres # Usuário do banco
POSTGRES_PASSWORD=postgres # Senha (ALTERAR EM PRODUÇÃO)
```
#### Validação de Proxies
```env
PROXY_TIMEOUT=10 # Timeout em segundos para teste
VALIDATION_URL=http://httpbin.org/ip # URL para validação
```
#### Scraping
```env
SCRAPING_DELAY=2.0 # Delay entre requisições (segundos)
MAX_RETRIES=3 # Tentativas em caso de erro
```
#### Agendamento
```env
SCHEDULE_HOUR_START=2 # Hora inicial (UTC)
SCHEDULE_HOUR_END=4 # Hora final (UTC)
```
O serviço executará automaticamente uma vez ao dia em um horário aleatório entre `SCHEDULE_HOUR_START` e `SCHEDULE_HOUR_END`.
#### Logging
```env
LOG_LEVEL=INFO # Níveis: DEBUG, INFO, WARNING, ERROR
```
### Arquivo de URLs (proxies.txt)
O arquivo `root/proxy/proxies.txt` contém as URLs para scraping:
```txt
# Comentários começam com #
https://www.proxy-list.download/api/v1/get?type=http
https://api.proxyscrape.com/v2/?request=get&protocol=http
# Sites com Selenium (paginação)
https://www.freeproxy.world/?type=http&anonymity=4
https://free-proxy-list.net/
```
**Formato**:
- Uma URL por linha
- Linhas começando com `#` são ignoradas
- URLs vazias são ignoradas
## Uso
### Comandos Docker Compose
**Iniciar todos os serviços**:
```bash
docker-compose up -d
```
**Iniciar com pgAdmin (gerenciamento do banco)**:
```bash
docker-compose --profile admin up -d
```
**Ver logs em tempo real**:
```bash
docker-compose logs -f proxy-scraper
```
**Parar serviços**:
```bash
docker-compose down
```
**Parar e remover volumes (limpar banco)**:
```bash
docker-compose down -v
```
**Reconstruir imagens**:
```bash
docker-compose build --no-cache
docker-compose up -d
```
### Executar Scraping Imediato
Para executar o scraping imediatamente (sem esperar o agendamento):
```bash
docker-compose exec proxy-scraper python src/main.py --immediate
```
### Acessar pgAdmin (opcional)
Se iniciou com o profile `admin`:
1. Acesse: http://localhost:5050
2. Login: `admin@admin.com` / `admin` (configurável no .env)
3. Adicione servidor:
- Host: `postgres`
- Port: `5432`
- Database: `proxies`
- Username: seu `POSTGRES_USER`
- Password: seu `POSTGRES_PASSWORD`
## Schema do Banco de Dados
### Tabela `proxies`
```sql
CREATE TABLE proxies (
id SERIAL PRIMARY KEY,
ip_address INET NOT NULL,
port INTEGER NOT NULL CHECK (port > 0 AND port <= 65535),
protocol VARCHAR(10) NOT NULL CHECK (protocol IN ('HTTP', 'HTTPS', 'SOCKS4', 'SOCKS5')),
username VARCHAR(255),
password VARCHAR(255),
country_code CHAR(2),
country_name VARCHAR(100),
city VARCHAR(100),
is_active BOOLEAN DEFAULT TRUE,
is_anonymous BOOLEAN DEFAULT FALSE,
response_time_ms INTEGER,
last_checked_at TIMESTAMP WITH TIME ZONE,
last_successful_at TIMESTAMP WITH TIME ZONE,
failure_count INTEGER DEFAULT 0,
success_count INTEGER DEFAULT 0,
usage INTEGER DEFAULT 0,
source VARCHAR(255),
notes TEXT,
created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP,
CONSTRAINT unique_proxy UNIQUE (ip_address, port, protocol)
);
```
### Consultas Úteis
**Listar todos os proxies ativos e anônimos**:
```sql
SELECT ip_address, port, protocol, country_name, response_time_ms
FROM proxies
WHERE is_active = TRUE AND is_anonymous = TRUE
ORDER BY response_time_ms ASC;
```
**Estatísticas gerais**:
```sql
SELECT
COUNT(*) as total,
COUNT(*) FILTER (WHERE is_active = TRUE) as active,
COUNT(*) FILTER (WHERE is_anonymous = TRUE) as anonymous,
COUNT(DISTINCT country_code) as countries,
AVG(response_time_ms) as avg_response_time
FROM proxies;
```
**Proxies por país**:
```sql
SELECT country_name, COUNT(*) as total
FROM proxies
WHERE is_active = TRUE AND is_anonymous = TRUE
GROUP BY country_name
ORDER BY total DESC;
```
**Proxies mais rápidos**:
```sql
SELECT ip_address, port, protocol, response_time_ms, country_name
FROM proxies
WHERE is_active = TRUE AND is_anonymous = TRUE
ORDER BY response_time_ms ASC
LIMIT 10;
```
## Funcionamento do Sistema
### Fluxo de Execução
1. **Agendamento**: Serviço aguarda horário programado (2h-4h UTC por padrão)
2. **Scraping**: Lê URLs do `proxies.txt` e processa uma por vez
3. **Parsing**: Extrai informações de proxy (IP, porta, protocolo)
4. **Deduplicação**: Remove duplicatas da lista scraped
5. **Validação**: Testa cada proxy para:
- Conectividade (timeout de 10s)
- Anonimato (verifica vazamento de IP real)
6. **Filtragem**: Mantém APENAS proxies anônimos
7. **Armazenamento**: Insere no PostgreSQL (ignora duplicatas)
8. **Estatísticas**: Exibe métricas do processamento
### Validação de Anonimato
O sistema verifica anonimato através de:
1. **Headers HTTP**: Detecta headers que revelam IP real:
- `X-Forwarded-For`
- `X-Real-IP`
- `Via`
- `Forwarded`
2. **Análise de Response**: Valida o IP retornado pela URL de teste
3. **Critério Conservador**: Em caso de dúvida, o proxy é marcado como não-anônimo
### Tipos de Scraper
**GenericHTMLScraper**:
- Para sites estáticos
- Parsing com BeautifulSoup
- Extrai de tabelas HTML ou texto
- Rápido e eficiente
**SeleniumScraper**:
- Para sites dinâmicos (JavaScript)
- Suporta paginação automática
- Sites como freeproxy.world
- Mais lento mas completo
## Monitoramento
### Logs
O sistema gera logs estruturados e coloridos:
```
2025-11-21 02:15:30 - INFO - Starting proxy scraping job
2025-11-21 02:15:31 - INFO - Scraped 150 proxies from sources
2025-11-21 02:15:45 - INFO - 45 proxies validated successfully
2025-11-21 02:15:46 - INFO - Inserted 38 new anonymous proxies
```
**Níveis de log**:
- **DEBUG**: Informações detalhadas de cada operação
- **INFO**: Progresso e estatísticas (padrão)
- **WARNING**: Problemas não-críticos
- **ERROR**: Erros que precisam atenção
### Health Check
O container possui health check integrado:
```bash
docker-compose ps
```
Verifica conectividade com o banco a cada 60 segundos.
### Métricas
Após cada execução, o sistema exibe:
- Total de proxies scraped
- Taxa de validação
- Proxies inseridos vs duplicados
- Estatísticas do banco
- Tempo de execução
## Troubleshooting
### Container não inicia
**Verificar logs**:
```bash
docker-compose logs proxy-scraper
```
**Problemas comuns**:
- Arquivo `proxies.txt` não existe
- Credenciais PostgreSQL incorretas
- PostgreSQL não está pronto (aguarde health check)
### Nenhum proxy é inserido
**Causas possíveis**:
1. Proxies não são anônimos (validação falha)
2. Proxies já existem no banco
3. Todos os proxies falharam na validação
**Verificar**:
```bash
# Ver logs detalhados
docker-compose logs proxy-scraper | grep -i "anonymous\|validated"
# Executar com nível DEBUG
# Edite .env: LOG_LEVEL=DEBUG
docker-compose restart proxy-scraper
```
### Selenium/Chrome não funciona
**Erro**: "Chrome binary not found"
**Solução**:
```bash
# Reconstruir imagem
docker-compose build --no-cache proxy-scraper
docker-compose up -d
```
### Problemas de conexão PostgreSQL
**Erro**: "Connection refused" ou "could not connect"
**Verificar**:
```bash
# Status do PostgreSQL
docker-compose ps postgres
# Logs do PostgreSQL
docker-compose logs postgres
# Testar conexão manual
docker-compose exec postgres psql -U postgres -d proxies -c "\dt"
```
### Performance lenta
**Otimizações**:
1. Ajuste `PROXY_TIMEOUT` para valor menor (padrão: 10s)
2. Reduza número de URLs em `proxies.txt`
3. Aumente workers de validação (edite `src/main.py`, `max_workers=20`)
## Segurança
### Recomendações para Produção
1. **Altere senhas padrão**:
```env
POSTGRES_PASSWORD=senha_forte_e_unica
PGADMIN_PASSWORD=outra_senha_forte
```
2. **Não exponha portas desnecessárias**:
- Remova `ports` do serviço `postgres` no `docker-compose.yml`
- Use apenas através de pgAdmin ou conexões internas
3. **Use volumes nomeados**:
- Já configurado no `docker-compose.yml`
- Dados persistem entre restarts
4. **Atualize regularmente**:
```bash
docker-compose pull
docker-compose build --no-cache
docker-compose up -d
```
5. **Firewall**:
- Bloqueie acesso externo às portas do Docker
- Use apenas localhost ou VPN
## Extensões e Customizações
### Adicionar novo scraper
Edite `src/scrapers.py`:
```python
class CustomScraper(ProxyScraper):
def scrape(self) -> List[Dict[str, Any]]:
# Sua lógica aqui
proxies = []
# ... scraping logic ...
return proxies
```
### Modificar critérios de anonimato
Edite `src/validator.py`, método `_check_anonymity()`:
```python
def _check_anonymity(self, response, proxy_ip):
# Customize validation logic
pass
```
### Adicionar campos ao banco
1. Modifique `init-db.sql`
2. Atualize models em `src/database.py`
3. Recrie o banco:
```bash
docker-compose down -v
docker-compose up -d
```
### Integrar com API externa
Modifique `src/main.py` para exportar ou notificar serviços externos após scraping.
## Performance
### Benchmarks Típicos
Com configurações padrão:
- **Scraping**: 100-500 proxies em 2-5 minutos
- **Validação**: 20 proxies/segundo (max_workers=20)
- **Armazenamento**: < 1 segundo
### Otimizações
- Pool de conexões PostgreSQL (já implementado)
- Validação concorrente com ThreadPoolExecutor
- Cache de webdriver no Selenium
- Índices otimizados no banco
## Suporte e Contribuições
### Estrutura do Código
- **Modular**: Cada arquivo tem responsabilidade única
- **Type Hints**: Código totalmente tipado
- **Documentado**: Docstrings em todas as funções
- **Error Handling**: Try/catch em operações críticas
- **Logging**: Rastreamento completo de execução
### Desenvolvimento Local
```bash
# Criar virtualenv
python -m venv venv
source venv/bin/activate # Linux/Mac
# ou
venv\Scripts\activate # Windows
# Instalar dependências
pip install -r requirements.txt
# Executar localmente (requer PostgreSQL rodando)
export POSTGRES_HOST=localhost
python src/main.py --immediate
```
