带回调的函数调用¶

这是一个可以在 FunctionTool 中应用一些人在回路中概念的功能。

基本上，添加了一个回调函数，它使开发者能够在代理交互过程中请求用户输入，并允许任何程序化操作。

os.environ["OPENAI_API_KEY"] = "sk-"

os.environ["OPENAI_API_KEY"] = "sk-"

此函数向用户显示为函数调用生成的数据，并请求用户输入以返回交互。

def callback(message):
    confirmation = input(
        f"{message[1]}\nDo you approve of sending this greeting?\nInput(Y/N):"
    )

    if confirmation.lower() == "y":
        # Here you can trigger an action such as sending an email, message, api call, etc.
        return "Greeting sent successfully."
    else:
        return (
            "Greeting has not been approved, talk a bit about how to improve"
        )

def callback(message): confirmation = input( f"{message[1]}\n你批准发送此问候语吗？\n输入(Y/N):" ) if confirmation.lower() == "y": # 你可以在此处触发诸如发送电子邮件、消息、API 调用等操作。 return "问候语发送成功。" else: return ( "问候语未获批准，请谈谈如何改进" )

只需要收件人和问候消息的简单函数。

def send_hello(destination: str, message: str) -> str:
    """
    Say hello with a rhyme
    destination: str - Name of recipient
    message: str - Greeting message with a rhyme to the recipient's name
    """

    return destination, message


hello_tool = FunctionTool.from_defaults(fn=send_hello, callback=callback)

def send_hello(destination: str, message: str) -> str: """ 使用押韵的问候语 destination: str - 收件人姓名 message: str - 包含与收件人姓名押韵的问候消息 """ return destination, message hello_tool = FunctionTool.from_defaults(fn=send_hello, callback=callback)

The hello message has been sent to Karen with the rhyme "Hello Karen, you're a star!"

response = agent.chat("Send hello to Joe")
print(str(response))

response = agent.chat("向 Joe 发送问候") print(str(response))

I have successfully sent a hello message to Joe with the greeting "Hello Joe, you're a pro!"
