什么是Firecrawl

Firecrawl 是一款 可以将网站转换为 便于AI处理的Markdown 格式的爬虫工具 ，主要 提供 API 服务 ，无需站点地图，只需要接收一个 URL 地址就可以爬取网站及网站下可访问的所有子页面内容。

本地部署Firecrawl

https://github.com/mendableai/firecrawl/blob/main/CONTRIBUTING.md

For a simpler setup, you can use Docker Compose to run all services:

1. Prerequisites: Make sure you have Docker and Docker Compose installed

2. Copy the .env.example file to .env in the /apps/api/ directory and configure as needed

3. From the root directory, run: docker compose up
   This will start Redis, the API server, and workers automatically in the correct configuration.

git clone https://github.com/mendableai/firecrawl.git
cd firecrawl

创建.env文件

cp apps/api/.env.example apps/api/.env

需要使用LLM的话修改一下OPENAI_API_KEY和OPENAI_BASE_URL

OPENAI_API_KEY=xxx 
OPENAI_BASE_URL=xxx

构建并启动

docker compose build
docker compose up -d

国内可能下载playwright很慢，可以修改「apps/playwright-service-ts/Dockerfile」

RUN echo "deb http://mirrors.aliyun.com/debian/ bookworm main non-free contrib\n\  
deb http://mirrors.aliyun.com/debian/ bookworm-updates main non-free contrib\n\  
deb http://mirrors.aliyun.com/debian-security bookworm-security main non-free contrib" > /etc/apt/sources.list  # Install Playwright dependencies  
ENV PLAYWRIGHT_DOWNLOAD_HOST=https://npmmirror.com/mirrors/playwright/  
RUN npx playwright install --with-deps

测试一下

curl -X GET http://localhost:3002/test

使用python调用

pip install firecrawl-py

import logging  
from firecrawl import FirecrawlApp  logging.basicConfig(level=logging.INFO)  
logger = logging.getLogger(__name__)  def main():  try:  app = FirecrawlApp(api_key=None, api_url="http://localhost:3002")  params = {  'formats': ['markdown'],  }  logger.info("开始抓取网页...")  scrape_status = app.scrape_url('https://www.kujiale.com/', params=params)  logger.info("抓取结果：")  print(scrape_status)  except Exception as e:  logger.error(f"抓取过程中发生错误: {str(e)}")  raise  if __name__ == "__main__":  main()

从结果可以看到它会提取一些内容，方便直接将数据给AI或者插入RAG中进行后续操作
