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，您需要获取一个令牌，如Slack API文档中所述。一旦您收到SLACK_USER_TOKEN，您可以将其作为环境变量输入到下方。

import getpass
import os

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

如果你想从单个工具的运行中获取自动追踪，你也可以通过取消注释以下内容来设置你的 LangSmith API 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

可选地，我们可以安装beautifulsoup4来帮助解析HTML消息：

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

实例化​

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 Reference:SlackToolkit

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：

在代理中使用​

让我们为代理配备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)
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()

for event in events:
    message = event["messages"][-1]
    if message.type != "tool":  # mask sensitive information
