LangChain 集成

LangChain 集成

将 HydraSkill 与 LangChain 的网页工具配合使用,实现可靠的 agent 浏览。

安装设置

pip install hydraskill langchain langchain-community

配合 WebBaseLoader

from hydraskill import ProxyClient
from langchain_community.document_loaders import WebBaseLoader

client = ProxyClient()
proxy = client.get_proxy(target="example.com", session_lock=True)

loader = WebBaseLoader(
    "https://example.com/article",
    proxies=proxy.to_dict()
)
docs = loader.load()

配合浏览器工具

from langchain.tools import Tool
from hydraskill import ProxyClient

client = ProxyClient()

def browse_with_proxy(url: str) -> str:
    proxy = client.get_proxy(target=url)
    response = requests.get(url, proxies=proxy.to_dict())
    return response.text

browse_tool = Tool(
    name="browse",
    func=browse_with_proxy,
    description="Browse a URL with proxy protection"
)

对 LangChain Agent 的优势

• Agent 可以浏览任何网站而不被 IP 封锁
• 长时间运行的调研任务保持会话连续性
• 多步网络交互不会被打断
• 无需在 agent 代码中添加重试逻辑
