Slack 工具包

这将帮助您开始使用 Slack 工具包。有关所有 SlackToolkit 功能和配置的详细文档，请前往 API 参考。

设置

要使用此工具包，您需要按照Slack API 文档中的说明获取一个令牌。一旦您收到 SLACK_USER_TOKEN，就可以将其作为下方的环境变量输入。

import getpass
import os

if not os.getenv("SLACK_USER_TOKEN"):
    os.environ["SLACK_USER_TOKEN"] = getpass.getpass("Enter your Slack user token: ")

要启用单个工具的自动跟踪，请设置您的LangSmithAPI密钥：

# os.environ["LANGSMITH_API_KEY"] = getpass.getpass("Enter your LangSmith API key: ")
# os.environ["LANGSMITH_TRACING"] = "true"

安装

这个工具包位于langchain-community包中。我们还需要Slack SDK:

%pip install -qU langchain-community slack_sdk

可以安装beautifulsoup4来辅助解析HTML消息（可选）:

%pip install -qU beautifulsoup4 # This is optional but is useful for parsing HTML messages

Instantiation

现在我们可以实例化我们的工具包:

from langchain_community.agent_toolkits import SlackToolkit

toolkit = SlackToolkit()

API 参考:Slack 工具包

工具

查看可用工具：

tools = toolkit.get_tools()

tools

[SlackGetChannel(client=<slack_sdk.web.client.WebClient object at 0x113caa8c0>),
 SlackGetMessage(client=<slack_sdk.web.client.WebClient object at 0x113caa4d0>),
 SlackScheduleMessage(client=<slack_sdk.web.client.WebClient object at 0x113caa440>),
 SlackSendMessage(client=<slack_sdk.web.client.WebClient object at 0x113caa410>)]

此工具包加载了:

• Slack获取频道
• Slack获取消息
• Slack计划消息
• Slack发送消息

使用于代理

让智能体配备Slack工具包，并查询有关频道的信息。

from langchain_openai import ChatOpenAI
from langgraph.prebuilt import create_react_agent

llm = ChatOpenAI(model="gpt-4o-mini")

agent_executor = create_react_agent(llm, tools)

API 参考:ChatOpenAI |create_react_agent

example_query = "When was the #general channel created?"

events = agent_executor.stream(
    {"messages": [("user", example_query)]},
    stream_mode="values",
)
for event in events:
    message = event["messages"][-1]
    if message.type != "tool":  # mask sensitive information
        event["messages"][-1].pretty_print()
