Scores range from 0.0 (lowest quality) to 1.0 (highest quality). + +**Q: Can I analyze password-protected pages?** +A: Yes! Use the `js_code` parameter to handle authentication, or include session cookies in the `headers` configuration. + +**Q: How many links can I analyze at once?** +A: There's no hard limit on the number of links per page, but very large pages (>10,000 links) may take longer to process. + +**Q: Can I filter out certain types of links?** +A: Use the `exclusion_patterns` parameter in the config to filter out unwanted links using regex patterns. + +**Q: Does this work with JavaScript-heavy sites?** +A: Absolutely! The crawler waits for JavaScript execution and can even run custom JavaScript using the `js_code` parameter. \ No newline at end of file diff --git a/mkdocs.yml b/mkdocs.yml index ff1485474..969f30a09 100644 --- a/mkdocs.yml +++ b/mkdocs.yml @@ -59,6 +59,7 @@ nav: - "Clustering Strategies": "extraction/clustring-strategies.md" - "Chunking": "extraction/chunking.md" - API Reference: + - "Docker Server API": "api/docker-server.md" - "AsyncWebCrawler": "api/async-webcrawler.md" - "arun()": "api/arun.md" - "arun_many()": "api/arun_many.md" diff --git a/tests/docker/extended_features/demo_adaptive_endpoint.py b/tests/docker/extended_features/demo_adaptive_endpoint.py new file mode 100644 index 000000000..d552b916e --- /dev/null +++ b/tests/docker/extended_features/demo_adaptive_endpoint.py @@ -0,0 +1,435 @@ +#!/usr/bin/env python3 +""" +Demo: How users will call the Adaptive Digest endpoint +This shows practical examples of how developers would use the adaptive crawling +feature to intelligently gather relevant content based on queries. +""" + +import asyncio +import time +from typing import Any, Dict, Optional + +import aiohttp + +# Configuration +API_BASE_URL = "http://localhost:11235" +API_TOKEN = None # Set if your API requires authentication + + +class AdaptiveEndpointDemo: + def __init__(self, base_url: str = API_BASE_URL, token: str = None): + self.base_url = base_url + self.headers = {"Content-Type": "application/json"} + if token: + self.headers["Authorization"] = f"Bearer {token}" + + async def submit_adaptive_job( + self, start_url: str, query: str, config: Optional[Dict] = None + ) -> str: + """Submit an adaptive crawling job and return task ID""" + payload = {"start_url": start_url, "query": query} + + if config: + payload["config"] = config + + async with aiohttp.ClientSession() as session: + async with session.post( + f"{self.base_url}/adaptive/digest/job", + headers=self.headers, + json=payload, + ) as response: + if response.status == 202: # Accepted + result = await response.json() + return result["task_id"] + else: + error_text = await response.text() + raise Exception(f"API Error {response.status}: {error_text}") + + async def check_job_status(self, task_id: str) -> Dict[str, Any]: + """Check the status of an adaptive crawling job""" + async with aiohttp.ClientSession() as session: + async with session.get( + f"{self.base_url}/adaptive/digest/job/{task_id}", headers=self.headers + ) as response: + if response.status == 200: + return await response.json() + else: + error_text = await response.text() + raise Exception(f"API Error {response.status}: {error_text}") + + async def wait_for_completion( + self, task_id: str, max_wait: int = 300 + ) -> Dict[str, Any]: + """Poll job status until completion or timeout""" + start_time = time.time() + + while time.time() - start_time < max_wait: + status = await self.check_job_status(task_id) + + if status["status"] == "COMPLETED": + return status + elif status["status"] == "FAILED": + raise Exception(f"Job failed: {status.get('error', 'Unknown error')}") + + print( + f"โณ Job {status['status']}...
