|

|
||||
|
||||
```bash
|
||||
# Submit LLM extraction job with webhook
|
||||
curl -X POST http://localhost:11235/llm/job \

|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/llm-complete",
|
||||
"webhook_data_in_payload": true,
|
||||
"webhook_headers": {
|
||||
"X-Webhook-Secret": "your-secret-token"
|
||||
}
|
||||
}
|
||||
}'
|
||||
|
||||
# Response: {"task_id": "llm_1234567890"}
|
||||
```
|
||||
|
||||
**Your webhook receives:**
|
||||
```json
|
||||
{
|
||||
"task_id": "llm_1234567890",
|
||||
"task_type": "llm_extraction",
|
||||
"status": "completed",
|
||||
"timestamp": "2025-10-22T12:30:00.000000+00:00",
|

"urls": ["https://example.com/article"],
|
||||
"data": {

"extracted_content": {

"title": "Understanding Web Scraping",
|
||||
"author": "John Doe",
|
||||
"main_points": ["Point 1", "Point 2", "Point 3"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Key Differences for LLM Jobs:**
|
||||
- Task type is `"llm_extraction"` instead of `"crawl"`
|
||||
- Extracted data is in `data.extracted_content`
|
||||
- Single URL only (not an array)
|
||||
- Supports schema-based extraction with `schema` parameter
|
||||
|
||||
> 💡 **Pro tip**: See [WEBHOOK_EXAMPLES.md](./WEBHOOK_EXAMPLES.md) for detailed examples including TypeScript client code, Flask webhook handlers, and failure handling.

🚀 Crawl4AI Docker Hooks System - Complete Examples
|
||||
====================================================
|
||||
|
||||
This file demonstrates the Docker Hooks System with three different approaches:
|
||||
|
||||
1. String-based hooks for REST API
|
||||
2. hooks_to_string() utility to convert functions
|
||||
3. Docker Client with automatic conversion (most convenient)
|
||||
|
||||
Requirements:
|
||||
- Docker container running: docker run -p 11235:11235 unclecode/crawl4ai:latest
|
||||
- crawl4ai installed: pip install crawl4ai
|
||||

### Creating a Profile Using the Crawl4AI CLI (Easiest)
|
||||
|
||||
If you prefer a guided, interactive setup, use the built-in CLI to create and manage persistent browser profiles.
|
||||
|
||||
1.⠀Launch the profile manager:
|
||||
```bash
|
||||
crwl profiles
|
||||
```
|
||||
|
||||
2.⠀Choose "Create new profile" and enter a profile name. A Chromium window opens so you can log in to sites and configure settings. When finished, return to the terminal and press `q` to save the profile.
|
||||
|
||||
3.⠀Profiles are saved under `~/.crawl4ai/profiles/<profile_name>` (for example: `/home/<you>/.crawl4ai/profiles/test_profile_1`) along with a `storage_state.json` for cookies and session data.
|
||||
|
||||
4.⠀Optionally, choose "List profiles" in the CLI to view available profiles and their paths.
|
||||
|
||||
5.⠀Use the saved path with `BrowserConfig.user_data_dir`:
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, BrowserConfig
|
||||
|
||||
profile_path = "/home/<you>/.crawl4ai/profiles/test_profile_1"
|
||||
|
||||
browser_config = BrowserConfig(
|
||||
headless=True,
|
||||
use_managed_browser=True,
|
||||
user_data_dir=profile_path,
|
||||
browser_type="chromium",
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
result = await crawler.arun(url="https://example.com/private")
|
||||
```
|
||||
|
||||
The CLI also supports listing and deleting profiles, and even testing a crawl directly from the menu.
|
||||
|
||||
---
|
||||
|
||||
## 3. Using Managed Browsers in Crawl4AI
|
||||
|
||||
Once you have a data directory with your session data, pass it to **`BrowserConfig`**:
|

# Proxy & Security
|
||||
|
||||
This guide covers proxy configuration and security features in Crawl4AI, including SSL certificate analysis and proxy rotation strategies.
|
||||
|
||||
## Understanding Proxy Configuration
|
||||
|
||||
Crawl4AI recommends configuring proxies per request through `CrawlerRunConfig.proxy_config`. This gives you precise control, enables rotation strategies, and keeps examples simple enough to copy, paste, and run.
|
||||
# Proxy
|
||||
|
||||
## Basic Proxy Setup
|
||||
|
||||
Configure proxies that apply to each crawl operation:
|
||||
Simple proxy configuration with `BrowserConfig`:
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig, ProxyConfig
|
||||
from crawl4ai.async_configs import BrowserConfig
|
||||
|
||||
run_config = CrawlerRunConfig(proxy_config=ProxyConfig(server="http://proxy.example.com:8080"))
|
||||
# run_config = CrawlerRunConfig(proxy_config={"server": "http://proxy.example.com:8080"})
|
||||
# run_config = CrawlerRunConfig(proxy_config="http://proxy.example.com:8080")
|
||||
# Using HTTP proxy
|
||||
browser_config = BrowserConfig(proxy_config={"server": "http://proxy.example.com:8080"})
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
result = await crawler.arun(url="https://example.com")
|
||||
|
||||
|
||||
async def main():
|
||||
browser_config = BrowserConfig()
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
result = await crawler.arun(url="https://example.com", config=run_config)
|
||||
print(f"Success: {result.success} -> {result.url}")
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(main())
|
||||
# Using SOCKS proxy
|
||||
browser_config = BrowserConfig(proxy_config={"server": "socks5://proxy.example.com:1080"})
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
result = await crawler.arun(url="https://example.com")
|
||||
```
|
||||
|
||||
!!! note "Why request-level?"
|
||||
`CrawlerRunConfig.proxy_config` keeps each request self-contained, so swapping proxies or rotation strategies is just a matter of building a new run configuration.
|
||||
## Authenticated Proxy
|
||||
|
||||
## Supported Proxy Formats
|
||||
|
||||
The `ProxyConfig.from_string()` method supports multiple formats:
|
||||
Use an authenticated proxy with `BrowserConfig`:
|
||||
|
||||
```python
|
||||
from crawl4ai import ProxyConfig
|
||||
from crawl4ai.async_configs import BrowserConfig
|
||||
|
||||
# HTTP proxy with authentication
|
||||
proxy1 = ProxyConfig.from_string("http://user:pass@192.168.1.1:8080")
|
||||
|
||||
# HTTPS proxy
|
||||
proxy2 = ProxyConfig.from_string("https://proxy.example.com:8080")
|
||||
|
||||
# SOCKS5 proxy
|
||||
proxy3 = ProxyConfig.from_string("socks5://proxy.example.com:1080")
|
||||
|
||||
# Simple IP:port format
|
||||
proxy4 = ProxyConfig.from_string("192.168.1.1:8080")
|
||||
|
||||
# IP:port:user:pass format
|
||||
proxy5 = ProxyConfig.from_string("192.168.1.1:8080:user:pass")
|
||||
browser_config = BrowserConfig(proxy_config={
|
||||
"server": "http://[host]:[port]",
|
||||
"username": "[username]",
|
||||
"password": "[password]",
|
||||
})
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
result = await crawler.arun(url="https://example.com")
|
||||
```
|
||||
|
||||
## Authenticated Proxies
|
||||
|
||||
For proxies requiring authentication:
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from crawl4ai import AsyncWebCrawler,BrowserConfig, CrawlerRunConfig, ProxyConfig
|
||||
|
||||
run_config = CrawlerRunConfig(
|
||||
proxy_config=ProxyConfig(
|
||||
server="http://proxy.example.com:8080",
|
||||
username="your_username",
|
||||
password="your_password",
|
||||
)
|
||||
)
|
||||
# Or dictionary style:
|
||||
# run_config = CrawlerRunConfig(proxy_config={
|
||||
# "server": "http://proxy.example.com:8080",
|
||||
# "username": "your_username",
|
||||
# "password": "your_password",
|
||||
# })
|
||||
|
||||
|
||||
async def main():
|
||||
browser_config = BrowserConfig()
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
result = await crawler.arun(url="https://example.com", config=run_config)
|
||||
print(f"Success: {result.success} -> {result.url}")
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
## Environment Variable Configuration
|
||||
|
||||
Load proxies from environment variables for easy configuration:
|
||||
|
||||
```python
|
||||
import os
|
||||
from crawl4ai import ProxyConfig, CrawlerRunConfig
|
||||
|
||||
# Set environment variable
|
||||
os.environ["PROXIES"] = "ip1:port1:user1:pass1,ip2:port2:user2:pass2,ip3:port3"
|
||||
|
||||
# Load all proxies
|
||||
proxies = ProxyConfig.from_env()
|
||||
print(f"Loaded {len(proxies)} proxies")
|
||||
|
||||
# Use first proxy
|
||||
if proxies:
|
||||
run_config = CrawlerRunConfig(proxy_config=proxies[0])
|
||||
```
|
||||
|
||||
## Rotating Proxies
|
||||
|
||||
Crawl4AI supports automatic proxy rotation to distribute requests across multiple proxy servers. Rotation is applied per request using a rotation strategy on `CrawlerRunConfig`.
|
||||
Example using a proxy rotation service dynamically:
|
||||
|
||||
### Proxy Rotation (recommended)
|
||||
```python
|
||||
import asyncio
|
||||
import re
|
||||
from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig, CacheMode, ProxyConfig
|
||||
from crawl4ai.proxy_strategy import RoundRobinProxyStrategy
|
||||
|
||||
from crawl4ai import (
|
||||
AsyncWebCrawler,
|
||||
BrowserConfig,
|
||||
CrawlerRunConfig,
|
||||
CacheMode,
|
||||
RoundRobinProxyStrategy,
|
||||
)
|
||||
import asyncio
|
||||
from crawl4ai import ProxyConfig
|
||||
async def main():
|
||||
# Load proxies from environment
|
||||
# Load proxies and create rotation strategy
|
||||
proxies = ProxyConfig.from_env()
|
||||
#eg: export PROXIES="ip1:port1:username1:password1,ip2:port2:username2:password2"
|
||||
if not proxies:
|
||||
print("No proxies found! Set PROXIES environment variable.")
|
||||
print("No proxies found in environment. Set PROXIES env variable!")
|
||||
return
|
||||
|
||||
# Create rotation strategy
|
||||
proxy_strategy = RoundRobinProxyStrategy(proxies)
|
||||
|
||||
# Configure per-request with proxy rotation
|
||||
# Create configs
|
||||
browser_config = BrowserConfig(headless=True, verbose=False)
|
||||
run_config = CrawlerRunConfig(
|
||||
cache_mode=CacheMode.BYPASS,
|
||||
proxy_rotation_strategy=proxy_strategy,
|
||||
proxy_rotation_strategy=proxy_strategy
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
urls = ["https://httpbin.org/ip"] * (len(proxies) * 2) # Test each proxy twice
|
||||
|
||||
print(f"🚀 Testing {len(proxies)} proxies with rotation...")
|
||||
results = await crawler.arun_many(urls=urls, config=run_config)
|
||||
print("\n📈 Initializing crawler with proxy rotation...")
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
print("\n🚀 Starting batch crawl with proxy rotation...")
|
||||
results = await crawler.arun_many(
|
||||
urls=urls,
|
||||
config=run_config
|
||||
)
|
||||
for result in results:
|
||||
if result.success:
|
||||
ip_match = re.search(r'(?:[0-9]{1,3}\.){3}[0-9]{1,3}', result.html)
|
||||
current_proxy = run_config.proxy_config if run_config.proxy_config else None
|
||||
|
||||
for i, result in enumerate(results):
|
||||
if result.success:
|
||||
# Extract IP from response
|
||||
ip_match = re.search(r'(?:[0-9]{1,3}\.){3}[0-9]{1,3}', result.html)
|
||||
if ip_match:
|
||||
detected_ip = ip_match.group(0)
|
||||
proxy_index = i % len(proxies)
|
||||
expected_ip = proxies[proxy_index].ip
|
||||
if current_proxy and ip_match:
|
||||
print(f"URL {result.url}")
|
||||
print(f"Proxy {current_proxy.server} -> Response IP: {ip_match.group(0)}")
|
||||
verified = ip_match.group(0) == current_proxy.ip
|
||||
if verified:
|
||||
print(f"✅ Proxy working! IP matches: {current_proxy.ip}")
|
||||
else:
|
||||
print("❌ Proxy failed or IP mismatch!")
|
||||
print("---")
|
||||
|
||||
print(f"✅ Request {i+1}: Proxy {proxy_index+1} -> IP {detected_ip}")
|
||||
if detected_ip == expected_ip:
|
||||
print(" 🎯 IP matches proxy configuration")
|
||||
else:
|
||||
print(f" ⚠️ IP mismatch (expected {expected_ip})")
|
||||
else:
|
||||
print(f"❌ Request {i+1}: Could not extract IP from response")
|
||||
else:
|
||||
print(f"❌ Request {i+1}: Failed - {result.error_message}")
|
||||
asyncio.run(main())
|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
## SSL Certificate Analysis
|
||||
|
||||
Combine proxy usage with SSL certificate inspection for enhanced security analysis. SSL certificate fetching is configured per request via `CrawlerRunConfig`.
|
||||
|
||||
### Per-Request SSL Certificate Analysis
|
||||
```python
|
||||
import asyncio
|
||||
from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig
|
||||
|
||||
run_config = CrawlerRunConfig(
|
||||
proxy_config={
|
||||
"server": "http://proxy.example.com:8080",
|
||||
"username": "user",
|
||||
"password": "pass",
|
||||
},
|
||||
fetch_ssl_certificate=True, # Enable SSL certificate analysis for this request
|
||||
)
|
||||
|
||||
|
||||
async def main():
|
||||
browser_config = BrowserConfig()
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
result = await crawler.arun(url="https://example.com", config=run_config)
|
||||
|
||||
if result.success:
|
||||
print(f"✅ Crawled via proxy: {result.url}")
|
||||
|
||||
# Analyze SSL certificate
|
||||
if result.ssl_certificate:
|
||||
cert = result.ssl_certificate
|
||||
print("🔒 SSL Certificate Info:")
|
||||
print(f" Issuer: {cert.issuer}")
|
||||
print(f" Subject: {cert.subject}")
|
||||
print(f" Valid until: {cert.valid_until}")
|
||||
print(f" Fingerprint: {cert.fingerprint}")
|
||||
|
||||
# Export certificate
|
||||
cert.to_json("certificate.json")
|
||||
print("💾 Certificate exported to certificate.json")
|
||||
else:
|
||||
print("⚠️ No SSL certificate information available")
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
## Security Best Practices
|
||||
|
||||
### 1. Proxy Rotation for Anonymity
|
||||
```python
|
||||
from crawl4ai import CrawlerRunConfig, ProxyConfig
|
||||
from crawl4ai.proxy_strategy import RoundRobinProxyStrategy
|
||||
|
||||
# Use multiple proxies to avoid IP blocking
|
||||
proxies = ProxyConfig.from_env("PROXIES")
|
||||
strategy = RoundRobinProxyStrategy(proxies)
|
||||
|
||||
# Configure rotation per request (recommended)
|
||||
run_config = CrawlerRunConfig(proxy_rotation_strategy=strategy)
|
||||
|
||||
# For a fixed proxy across all requests, just reuse the same run_config instance
|
||||
static_run_config = run_config
|
||||
```
|
||||
|
||||
### 2. SSL Certificate Verification
|
||||
```python
|
||||
from crawl4ai import CrawlerRunConfig
|
||||
|
||||
# Always verify SSL certificates when possible
|
||||
# Per-request (affects specific requests)
|
||||
run_config = CrawlerRunConfig(fetch_ssl_certificate=True)
|
||||
```
|
||||
|
||||
### 3. Environment Variable Security
|
||||
```bash
|
||||
# Use environment variables for sensitive proxy credentials
|
||||
# Avoid hardcoding usernames/passwords in code
|
||||
export PROXIES="ip1:port1:user1:pass1,ip2:port2:user2:pass2"
|
||||
```
|
||||
|
||||
### 4. SOCKS5 for Enhanced Security
|
||||
```python
|
||||
from crawl4ai import CrawlerRunConfig
|
||||
|
||||
# Prefer SOCKS5 proxies for better protocol support
|
||||
run_config = CrawlerRunConfig(proxy_config="socks5://proxy.example.com:1080")
|
||||
```
|
||||
|
||||
## Migration from Deprecated `proxy` Parameter
|
||||
|
||||
!!! warning "Deprecation Notice"
|
||||
The legacy `proxy` argument on `BrowserConfig` is deprecated. Configure proxies through `CrawlerRunConfig.proxy_config` so each request fully describes its network settings.
|
||||
|
||||
```python
|
||||
# Old (deprecated) approach
|
||||
# from crawl4ai import BrowserConfig
|
||||
# browser_config = BrowserConfig(proxy="http://proxy.example.com:8080")
|
||||
|
||||
# New (preferred) approach
|
||||
from crawl4ai import CrawlerRunConfig
|
||||
run_config = CrawlerRunConfig(proxy_config="http://proxy.example.com:8080")
|
||||
```
|
||||
|
||||
### Safe Logging of Proxies
|
||||
```python
|
||||
from crawl4ai import ProxyConfig
|
||||
|
||||
def safe_proxy_repr(proxy: ProxyConfig):
|
||||
if getattr(proxy, "username", None):
|
||||
return f"{proxy.server} (auth: ****)"
|
||||
return proxy.server
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
???+ question "Proxy connection failed"
|
||||
- Verify the proxy server is reachable from your network.
|
||||
- Double-check authentication credentials.
|
||||
- Ensure the protocol matches (`http`, `https`, or `socks5`).
|
||||
|
||||
???+ question "SSL certificate errors"
|
||||
- Some proxies break SSL inspection; switch proxies if you see repeated failures.
|
||||
- Consider temporarily disabling certificate fetching to isolate the issue.
|
||||
|
||||
???+ question "Environment variables not loading"
|
||||
- Confirm `PROXIES` (or your custom env var) is set before running the script.
|
||||
- Check formatting: `ip:port:user:pass,ip:port:user:pass`.
|
||||
|
||||
???+ question "Proxy rotation not working"
|
||||
- Ensure `ProxyConfig.from_env()` actually loaded entries (`len(proxies) > 0`).
|
||||
- Attach `proxy_rotation_strategy` to `CrawlerRunConfig`.
|
||||
- Validate the proxy definitions you pass into the strategy.

## Job Queue & Webhook API
|
||||
|
||||
The Docker deployment includes a powerful asynchronous job queue system with webhook support for both crawling and LLM extraction tasks. Instead of waiting for long-running operations to complete, submit jobs and receive real-time notifications via webhooks when they finish.
|
||||
|
||||
### Why Use the Job Queue API?
|
||||
|
||||
**Traditional Synchronous API (`/crawl`):**
|
||||
- Client waits for entire crawl to complete
|
||||
- Timeout issues with long-running crawls
|
||||
- Resource blocking during execution
|
||||
- Constant polling required for status updates
|
||||
|
||||
**Asynchronous Job Queue API (`/crawl/job`, `/llm/job`):**
|
||||
- ✅ Submit job and continue immediately
|
||||
- ✅ No timeout concerns for long operations
|
||||
- ✅ Real-time webhook notifications on completion
|
||||
- ✅ Better resource utilization
|
||||
- ✅ Perfect for batch processing
|
||||
- ✅ Ideal for microservice architectures
|
||||
|
||||

### Usage Examples
|
||||
|
||||
#### Example 1: Python with Webhook Handler (Flask)
|
||||
|
||||
```python
|
||||
from flask import Flask, request, jsonify
|
||||
import requests
|
||||
|
||||
app = Flask(__name__)
|
||||
|
||||
# Webhook handler
|
||||
@app.route('/webhook/crawl-complete', methods=['POST'])
|
||||
def handle_crawl_webhook():
|
||||
payload = request.json
|
||||
|
||||
if payload['status'] == 'completed':
|
||||
print(f"✅ Job {payload['task_id']} completed!")
|
||||
print(f"Task type: {payload['task_type']}")
|
||||
|
||||
# Access the crawl results
|
||||
if 'data' in payload:
|
||||
markdown = payload['data'].get('markdown', '')
|
||||
extracted = payload['data'].get('extracted_content', {})
|
||||
print(f"Extracted {len(markdown)} characters")
|
||||
print(f"Structured data: {extracted}")
|
||||
else:
|
||||
print(f"❌ Job {payload['task_id']} failed: {payload.get('error')}")
|
||||
|
||||
return jsonify({"status": "received"}), 200
|
||||
|
||||
# Submit a crawl job with webhook
|
||||
def submit_crawl_job():
|
||||
response = requests.post(
|
||||
"http://localhost:11235/crawl/job",
|
||||
json={
|
||||
"urls": ["https://example.com"],
|
||||
"extraction_strategy": {
|
||||
"type": "JsonCssExtractionStrategy",
|
||||
"schema": {
|
||||
"name": "Example Schema",
|
||||
"baseSelector": "body",
|
||||
"fields": [
|
||||
{"name": "title", "selector": "h1", "type": "text"},
|
||||
{"name": "description", "selector": "meta[name='description']", "type": "attribute", "attribute": "content"}
|
||||
]
|
||||
}
|
||||
},
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://your-app.com/webhook/crawl-complete",
|
||||
"webhook_data_in_payload": True,
|
||||
"webhook_headers": {
|
||||
"X-Webhook-Secret": "your-secret-token"
|
||||
}
|
||||
}
|
||||
}
|
||||
)
|
||||
|
||||
task_id = response.json()['task_id']
|
||||
print(f"Job submitted: {task_id}")
|
||||
return task_id
|
||||
|
||||
if __name__ == '__main__':
|
||||
app.run(port=5000)
|
||||
```
|
||||
|
||||
#### Example 2: LLM Extraction with Webhooks
|
||||
|
||||
```python
|
||||
import requests
|
||||
|
||||
def submit_llm_job_with_webhook():
|
||||
response = requests.post(
|
||||
"http://localhost:11235/llm/job",
|
||||
json={
|
||||
"url": "https://example.com/article",
|
||||
"q": "Extract the article title, author, and main points",
|
||||
"provider": "openai/gpt-4o-mini",
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://your-app.com/webhook/llm-complete",
|
||||
"webhook_data_in_payload": True,
|
||||
"webhook_headers": {
|
||||
"X-Webhook-Secret": "your-secret-token"
|
||||
}
|
||||
}
|
||||
}
|
||||
)
|
||||
|
||||
task_id = response.json()['task_id']
|
||||
print(f"LLM job submitted: {task_id}")
|
||||
return task_id
|
||||
|
||||
# Webhook handler for LLM jobs
|
||||
@app.route('/webhook/llm-complete', methods=['POST'])
|
||||
def handle_llm_webhook():
|
||||
payload = request.json
|
||||
|
||||
if payload['status'] == 'completed':
|
||||
extracted = payload['data']['extracted_content']
|
||||
print(f"✅ LLM extraction completed!")
|
||||
print(f"Results: {extracted}")
|
||||
else:
|
||||
print(f"❌ LLM extraction failed: {payload.get('error')}")
|
||||
|
||||
return jsonify({"status": "received"}), 200
|
||||
```
|
||||
|
||||
#### Example 3: Without Webhooks (Polling)
|
||||
|
||||
If you don't use webhooks, you can poll for results:
|
||||
|
||||
```python
|
||||
import requests
|
||||
import time
|
||||
|
||||
# Submit job
|
||||
response = requests.post(
|
||||
"http://localhost:11235/crawl/job",
|
||||
json={"urls": ["https://example.com"]}
|
||||
)
|
||||
task_id = response.json()['task_id']
|
||||
|
||||
# Poll for results
|
||||
while True:
|
||||
result = requests.get(f"http://localhost:11235/job/{task_id}")
|
||||
data = result.json()
|
||||
|
||||
if data['status'] == 'completed':
|
||||
print("Job completed!")
|
||||
print(data['result'])
|
||||
break
|
||||
elif data['status'] == 'failed':
|
||||
print(f"Job failed: {data.get('error')}")
|
||||
break
|
||||
|
||||
print("Still processing...")
|
||||
time.sleep(2)
|
||||
```
|
||||
|
||||
#### Example 4: Global Webhook Configuration
|
||||
|
||||
Set a default webhook URL in your `config.yml` to avoid repeating it in every request:
|
||||
|
||||
```yaml
|
||||
# config.yml
|
||||
api:
|
||||
crawler:
|
||||
# ... other settings ...
|
||||
webhook:
|
||||
default_url: "https://your-app.com/webhook/default"
|
||||
default_headers:
|
||||
X-Webhook-Secret: "your-secret-token"
|
||||
```
|
||||
|
||||
Then submit jobs without webhook config:
|
||||
|
||||
```python
|
||||
# Uses the global webhook configuration
|
||||
response = requests.post(
|
||||
"http://localhost:11235/crawl/job",
|
||||
json={"urls": ["https://example.com"]}
|
||||
)
|
||||
```
|
||||
|
||||
### Webhook Best Practices
|
||||
|
||||
1. **Authentication:** Always use custom headers for webhook authentication
|
||||
```json
|
||||
"webhook_headers": {
|
||||
"X-Webhook-Secret": "your-secret-token"
|
||||
}
|
||||
```
|
||||
|
||||
2. **Idempotency:** Design your webhook handler to be idempotent (safe to receive duplicate notifications)
|
||||
|
||||
3. **Fast Response:** Return HTTP 200 quickly; process data asynchronously if needed
|
||||
```python
|
||||
@app.route('/webhook', methods=['POST'])
|
||||
def webhook():
|
||||
payload = request.json
|
||||
# Queue for background processing
|
||||
queue.enqueue(process_webhook, payload)
|
||||
return jsonify({"status": "received"}), 200
|
||||
```
|
||||
|
||||
4. **Error Handling:** Handle both success and failure notifications
|
||||
```python
|
||||
if payload['status'] == 'completed':
|
||||
# Process success
|
||||
elif payload['status'] == 'failed':
|
||||
# Log error, retry, or alert
|
||||
```
|
||||
|
||||
5. **Validation:** Verify webhook authenticity using custom headers
|
||||
```python
|
||||
secret = request.headers.get('X-Webhook-Secret')
|
||||
if secret != os.environ['EXPECTED_SECRET']:
|
||||
return jsonify({"error": "Unauthorized"}), 401
|
||||
```
|
||||
|
||||
6. **Logging:** Log webhook deliveries for debugging
|
||||
```python
|
||||
logger.info(f"Webhook received: {payload['task_id']} - {payload['status']}")
|
||||
```
|
||||
|
||||
### Use Cases
|
||||
|
||||
**1. Batch Processing**
|
||||
Submit hundreds of URLs and get notified as each completes:
|
||||
```python
|
||||
urls = ["https://site1.com", "https://site2.com", ...]
|
||||
for url in urls:
|
||||
submit_crawl_job(url, webhook_url="https://app.com/webhook")
|
||||
```
|
||||
|
||||
**2. Microservice Integration**
|
||||
Integrate with event-driven architectures:
|
||||
```python
|
||||
# Service A submits job
|
||||
task_id = submit_crawl_job(url)
|
||||
|
||||
# Service B receives webhook and triggers next step
|
||||
@app.route('/webhook')
|
||||
def webhook():
|
||||
process_result(request.json)
|
||||
trigger_next_service()
|
||||
return "OK", 200
|
||||
```
|
||||
|
||||
**3. Long-Running Extractions**
|
||||
Handle complex LLM extractions without timeouts:
|
||||
```python
|
||||
submit_llm_job(
|
||||
url="https://long-article.com",
|
||||
q="Comprehensive summary with key points and analysis",
|
||||
webhook_url="https://app.com/webhook/llm"
|
||||
)
|
||||
```
|
||||
|
||||
### Troubleshooting
|
||||
|
||||
**Webhook not receiving notifications?**
|
||||
- Check your webhook URL is publicly accessible
|
||||
- Verify firewall/security group settings
|
||||
- Use webhook testing tools like webhook.site for debugging
|
||||
- Check server logs for delivery attempts
|
||||
- Ensure your handler returns 200-299 status code
|
||||
|
||||
**Job stuck in processing?**
|
||||
- Check Redis connection: `docker logs <container_name> | grep redis`
|
||||
- Verify worker processes: `docker exec <container_name> ps aux | grep worker`
|
||||
- Check server logs: `docker logs <container_name>`
|
||||
|
||||
**Need to cancel a job?**
|
||||
Jobs are processed asynchronously. If you need to cancel:
|
||||
- Delete the task from Redis (requires Redis CLI access)
|
||||
- Or implement a cancellation endpoint in your webhook handler
|
