Never Commit Credentials - -```bash -# Add to .gitignore -echo "config/platforms/credentials.yaml" >> .gitignore -``` - -### 2. Use Environment Variables (Alternative) - -```bash -export DISCORD_USERNAME="your@email.com" -export DISCORD_PASSWORD="your_password" -``` - -Then in code: -```python -import os -username = os.getenv("DISCORD_USERNAME") -``` - -### 3. Encrypt Credentials File - -```bash -# Encrypt -gpg --symmetric --cipher-algo AES256 credentials.yaml - -# Decrypt -gpg --decrypt credentials.yaml.gpg > credentials.yaml -``` - -### 4. Use Vault for Production - -```python -import hvac - -vault_client = hvac.Client(url='http://vault:8200') -secret = vault_client.secrets.kv.v2.read_secret_version(path='credentials') -credentials = secret['data']['data'] -``` - ---- - -## 🐛 Troubleshooting - -### Issue: Chrome won't start - -**Solution**: -```bash -# Check if Chrome is installed -which google-chrome chromium-browser chromium - -# Kill existing Chrome processes -pkill -9 chrome - -# Try with visible browser (remove headless flag) -# Edit cdp_websocket_server.py: -# Remove "--headless=new" from cmd list -``` - -### Issue: CDP connection fails - -**Solution**: -```bash -# Check if port is already in use -lsof -i :9222 - -# Use different port range -# Edit cdp_websocket_server.py: -base_port = 10000 # Instead of 9222 -``` - -### Issue: Login fails - -**Solution**: -1. Check credentials are correct -2. Check for CAPTCHA (may require manual intervention) -3. Check for 2FA (add 2FA token to workflow) -4. Update selectors if platform UI changed - -### Issue: Selectors not found - -**Solution**: -```bash -# Test selectors manually with Chrome DevTools: -# 1. Open target platform -# 2. Press F12 -# 3. Console: document.querySelector("your selector") -# 4. Update YAML config with correct selectors -``` - ---- - -## 📊 Monitoring & Logging - -### View Logs - -```bash -# Real-time logs -tail -f cdp_server.log - -# Filter by platform -grep "discord" cdp_server.log - -# Filter by level -grep "ERROR" cdp_server.log -``` - -### Enable Debug Logging - -```python -# In cdp_websocket_server.py -logging.basicConfig(level=logging.DEBUG) -``` - ---- - -## 🚀 Production Deployment - -### 1. Use Supervisor/Systemd - -```ini -# /etc/supervisor/conf.d/cdp-server.conf -[program:cdp-server] -command=/usr/bin/python3 /path/to/cdp_websocket_server.py -directory=/path/to/maxun -user=maxun -autostart=true -autorestart=true -stderr_logfile=/var/log/cdp-server.err.log -stdout_logfile=/var/log/cdp-server.out.log -``` - -### 2. Add Health Checks - -```python -# Add to server -async def health_check(websocket, path): - if path == "/health": - await websocket.send(json.dumps({"status": "healthy"})) -``` - -### 3. Add Metrics - -```python -from prometheus_client import Counter, Histogram - -message_count = Counter('messages_sent_total', 'Total messages sent') -execution_time = Histogram('execution_duration_seconds', 'Execution time') -``` - ---- - -## 📚 API Reference - -### OpenAI Request Format - -```json -{ - "model": "maxun-robot-{platform}", - "messages": [ - {"role": "system", "content": "Platform: {platform}"}, - {"role": "user", "content": "{your_message}"} -

-### DON'T: -❌ Hardcode credentials in source code -❌ Commit credentials to version control -❌ Share credentials in plain text -❌ Use the same password everywhere -❌ Ignore rate limits -❌ Run without monitoring - ---- - -## 🔧 Troubleshooting - -### Issue: Login Fails - -**Solution**: -- Check if credentials are correct -- Verify platform hasn't changed login UI -- Check for CAPTCHA requirements -- Look for 2FA prompts -- Update recording with new selectors - -### Issue: Message Not Sent - -**Solution**: -- Verify message input selector -- Check for character limits -- Look for blocked content -- Ensure proper waits between steps -- Check network connection - -### Issue: Messages Not Retrieved - -**Solution**: -- Update extraction selectors -- Scroll more to load messages -- Wait longer for page load -- Check for lazy loading -- Verify conversation URL - ---- - -## 📈 Performance Optimization - -### Headless Mode (Production) - -```python -# Enable headless mode for faster execution -result = client.execute_recording( - recording_id=recording_id, - parameters={ - **credentials, - "headless": True # No browser UI - } -) -``` - -### Parallel Execution - -```python -from concurrent.futures import ThreadPoolExecutor - -def send_message(channel): - return client.execute_recording(recording_id, channel) - -with ThreadPoolExecutor(max_workers=5) as executor: - futures = [executor.submit(send_message, ch) for ch in channels] - results = [f.result() for f in futures] -``` - -### Caching Sessions - -```python -# Reuse authenticated sessions -session_recording = client.create_recording( -
