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/tests/test_docker.py b/tests/test_docker.py index c507ae56..3a2957dc 100644 --- a/tests/test_docker.py +++ b/tests/test_docker.py @@ -70,6 +70,7 @@ def test_docker_deployment(version="basic"): # test_llm_extraction(tester) # test_llm_with_ollama(tester) # test_screenshot(tester) + test_link_analysis(tester) def test_basic_crawl(tester: Crawl4AiTester): @@ -293,6 +294,77 @@ def test_screenshot(tester: Crawl4AiTester): assert result["result"]["success"] +def test_link_analysis(tester: Crawl4AiTester): + print("\n=== Testing Link Analysis ===") + + # Get auth token first + try: + token_response = requests.post(f"{tester.base_url}/token", json={"email": "test@example.com"}) + token = token_response.json()["access_token"] + headers = {"Authorization": f"Bearer {token}", "Content-Type": "application/json"} + except Exception as e: + print(f"Could not get auth token: {e}") + headers = {"Content-Type": "application/json"} + + # Test basic link analysis + request_data = { + "url": "https://www.nbcnews.com/business" + } + + response = requests.post( + f"{tester.base_url}/links/analyze", + headers=headers, + json=request_data, + timeout=60 + ) + + if response.status_code == 200: + result = response.json() + total_links = sum(len(links) for links in result.values()) + print(f"Link analysis successful: found {total_links} links") + + # Check for expected categories + categories_found = [] + for category in ['internal', 'external', 'social', 'download', 'email', 'phone']: + if category in result and result[category]: + categories_found.append(category) + + print(f"Link categories found: {categories_found}") + + # Verify we have some links + assert total_links > 0, "Should find at least one link" + assert len(categories_found) > 0, "Should find at least one link category" + + # Test with configuration + request_data_with_config = { + "url": "https://www.nbcnews.com/business", + "config": { + "simulate_user": True, + "override_navigator": True, + "word_count_threshold": 1 + } + } + + response_with_config = requests.post( + f"{tester.base_url}/links/analyze", + headers=headers, + json=request_data_with_config, + timeout=60 + ) + + if response_with_config.status_code == 200: + result_with_config = response_with_config.json() + total_links_config = sum(len(links) for links in result_with_config.values()) + print(f"Link analysis with config: found {total_links_config} links") + assert total_links_config > 0, "Should find links even with config" + + print("✅ Link analysis tests passed") + else: + print(f"❌ Link analysis failed: {response.status_code} -
