想用 Python 从零搭一套能把网页内容直接喂给 RAG 的爬虫管道吗？这篇保姆级教程教你用 Crawlee 搞定 robots、截图和分块导出。
本教程使用 Crawlee for Python 搭建完整的网页爬取工作流。通过 BeautifulSoupCrawler、ParselCrawler 和 PlaywrightCrawler 分别爬取静态与动态内容，提取标题、元数据和产品字段。教程还演示如何构建链接图，并将数据导出为 JSON、CSV 以及 RAG 就绪的 JSONL 分块文件。最后附带 robots 处理与截图功能，从设置到 AI 输出一步到位。
Crawlee for Python: Build a Web Crawling Pipeline with Robots Handling, Link Graphs, and RAG Chunk Export
In this tutorial, we build a complete Crawlee for Python workflow from setup to AI-ready output. We generate a local demo website, then crawl it with BeautifulSoupCrawler, ParselCrawler, and PlaywrightCrawler. We extract titles, metadata, product fields, and JavaScript-rendered cards, and capture full-page screenshots. We then normalize the data, build a link graph, and export JSON, CSV, and RAG-ready JSONL chunks.
