From 201843a2046b5fe882e17d92efafcc88a53afc4a Mon Sep 17 00:00:00 2001 From: AHMET YILMAZ Date: Tue, 7 Oct 2025 18:51:13 +0800 Subject: [PATCH] Add comprehensive tests for anti-bot strategies and extended features - Implemented `test_adapter_verification.py` to verify correct usage of browser adapters. - Created `test_all_features.py` for a comprehensive suite covering URL seeding, adaptive crawling, browser adapters, proxy rotation, and dispatchers. - Developed `test_anti_bot_strategy.py` to validate the functionality of various anti-bot strategies. - Added `test_antibot_simple.py` for simple testing of anti-bot strategies using async web crawling. - Introduced `test_bot_detection.py` to assess adapter performance against bot detection mechanisms. - Compiled `test_final_summary.py` to provide a detailed summary of all tests and their results. --- .gitignore | 3 + deploy/docker/README.md | 218 ++++ deploy/docker/api.py | 36 +- deploy/docker/crawler_pool.py | 21 +- deploy/docker/routers/adaptive.py | 166 ++- deploy/docker/routers/dispatchers.py | 259 ++++ deploy/docker/routers/scripts.py | 223 +++- deploy/docker/schemas.py | 49 + deploy/docker/server.py | 973 +++++++++++++- deploy/docker/utils.py | 125 ++ docs/md_v2/api/docker-server.md | 1142 +++++++++++++++++ mkdocs.yml | 1 + .../demo_adaptive_endpoint.py | 435 +++++++ .../extended_features}/demo_proxy_rotation.py | 0 .../extended_features/demo_seed_endpoint.py | 300 +++++ .../extended_features}/quick_proxy_test.py | 0 .../extended_features/test_adapter_chain.py | 91 ++ .../test_adapter_verification.py | 109 ++ .../extended_features/test_all_features.py | 645 ++++++++++ .../test_anti_bot_strategy.py | 175 +++ .../extended_features/test_antibot_simple.py | 115 ++ .../extended_features/test_bot_detection.py | 90 ++ .../extended_features/test_final_summary.py | 185 +++ 23 files changed, 5265 insertions(+), 96 deletions(-) create mode 100644 deploy/docker/routers/dispatchers.py create mode 100644 docs/md_v2/api/docker-server.md create mode 100644 tests/docker/extended_features/demo_adaptive_endpoint.py rename tests/{ => docker/extended_features}/demo_proxy_rotation.py (100%) create mode 100644 tests/docker/extended_features/demo_seed_endpoint.py rename tests/{ => docker/extended_features}/quick_proxy_test.py (100%) create mode 100644 tests/docker/extended_features/test_adapter_chain.py create mode 100644 tests/docker/extended_features/test_adapter_verification.py create mode 100644 tests/docker/extended_features/test_all_features.py create mode 100644 tests/docker/extended_features/test_anti_bot_strategy.py create mode 100644 tests/docker/extended_features/test_antibot_simple.py create mode 100644 tests/docker/extended_features/test_bot_detection.py create mode 100644 tests/docker/extended_features/test_final_summary.py diff --git a/.gitignore b/.gitignore index 452d4176..d4096264 100644 --- a/.gitignore +++ b/.gitignore @@ -1,6 +1,9 @@ # Scripts folder (private tools) .scripts/ +# Docker automation scripts (personal use) +docker-scripts/ + # Byte-compiled / optimized / DLL files __pycache__/ *.py[cod] diff --git a/deploy/docker/README.md b/deploy/docker/README.md index d35050cc..0f178d4d 100644 --- a/deploy/docker/README.md +++ b/deploy/docker/README.md @@ -13,6 +13,7 @@ - [Understanding Request Schema](#understanding-request-schema) - [REST API Examples](#rest-api-examples) - [Additional API Endpoints](#additional-api-endpoints) + - [Dispatcher Management](#dispatcher-management) - [HTML Extraction Endpoint](#html-extraction-endpoint) - [Screenshot Endpoint](#screenshot-endpoint) - [PDF Export Endpoint](#pdf-export-endpoint) @@ -34,6 +35,8 @@ - [Configuration Tips and Best Practices](#configuration-tips-and-best-practices) - [Customizing Your Configuration](#customizing-your-configuration) - [Configuration Recommendations](#configuration-recommendations) +- [Testing & Validation](#testing--validation) + - [Dispatcher Demo Test Suite](#dispatcher-demo-test-suite) - [Getting Help](#getting-help) - [Summary](#summary) @@ -332,6 +335,134 @@ Access the MCP tool schemas at `http://localhost:11235/mcp/schema` for detailed In addition to the core `/crawl` and `/crawl/stream` endpoints, the server provides several specialized endpoints: +### Dispatcher Management + +The server supports multiple dispatcher strategies for managing concurrent crawling operations.

+ - `X-RateLimit-Remaining` + - `X-RateLimit-Reset` + +--- + +## Best Practices + +### 1. Authentication + +Always store tokens securely and refresh before expiration: + +```python +class Crawl4AIClient: + def __init__(self, email, base_url="http://localhost:11235"): + self.email = email + self.base_url = base_url + self.token = None + self.refresh_token() + + def refresh_token(self): + response = requests.post( + f"{self.base_url}/token", + json={"email": self.email} + ) + self.token = response.json()["access_token"] + + def get_headers(self): + return { + "Authorization": f"Bearer {self.token}", + "Content-Type": "application/json" + } +``` + +### 2. Batch Processing + +For multiple URLs, use the batch crawl endpoint: + +```python +client = Crawl4AIClient("your@email.com") + +response = requests.post( + f"{client.base_url}/crawl", + headers=client.get_headers(), + json={ + "urls": [ + "https://example.com/page1", + "https://example.com/page2", + "https://example.com/page3" + ], + "dispatcher": "memory_adaptive" + } +) +``` + +### 3. Error Handling + +Always implement proper error handling: + +```python +try: + response = requests.post(url, headers=headers, json=payload) + response.raise_for_status() + data = response.json() +except requests.exceptions.HTTPError as e: + if e.response.status_code == 429: + print("Rate limit exceeded, waiting...") + time.sleep(60) + else: + print(f"HTTP error: {e}") +except requests.exceptions.RequestException as e: + print(f"Request failed: {e}") +``` + +### 4.
