Spider 集成

使用 LangChain Python 与 Spider 文档加载器集成。

Spider 是最快且最经济的爬虫和抓取工具，能够返回适用于 LLM 的数据。

安装

pip install spider-client

使用方法

使用 spider 需要从 spider.cloud 获取 API 密钥。

from langchain_community.document_loaders import SpiderLoader

loader = SpiderLoader(
    api_key="YOUR_API_KEY",
    url="https://spider.cloud",
    mode="scrape",  # 如果未提供 API 密钥，则会在环境变量中查找 SPIDER_API_KEY
)

data = loader.load()
print(data)
