设置
设置 API 凭证
要使用 Naver 搜索，您需要获取 API 凭证。请按照以下步骤操作
登录 Naver 开发者门户。创建一个新的应用程序并启用 Search API。从“应用程序列表”部分获取您的 NAVER_CLIENT_ID 和 NAVER_CLIENT_SECRET。
设置环境变量
获取凭证后，将它们设置为脚本中的环境变量
%pip install --upgrade --quiet langchain-naver-community
import getpass
import os
if not os.environ.get("NAVER_CLIENT_ID"):
os.environ["NAVER_CLIENT_ID"] = getpass.getpass("Enter your Naver Client ID:\n")
if not os.environ.get("NAVER_CLIENT_SECRET"):
os.environ["NAVER_CLIENT_SECRET"] = getpass.getpass(
"Enter your Naver Client Secret:\n"
)

在代理中使用
Naver 搜索工具可以集成到 LangChain 代理中，以执行更复杂的任务。下面我们演示如何设置一个可以搜索 Naver 以获取当前信息的代理。
from langchain_openai import ChatOpenAI
llm = ChatOpenAI(model="gpt-4o-mini")
system_prompt = """
You are a helpful assistant that can search the web for information.
"""
API 参考：ChatOpenAI
from langchain_naver_community.tool import NaverNewsSearch
from langgraph.prebuilt import create_react_agent
tools = [NaverNewsSearch()]
agent_executor = create_react_agent(
llm,
tools,
prompt=system_prompt,
)
API 参考：create_react_agent
现在我们可以使用查询运行代理了。
query = "What is the weather in Seoul?"
result = agent_executor.invoke({"messages": [("human", query)]})
result["messages"][-1].content
