带回调的函数调用¶

这是一项允许在 FunctionTool 中应用人机交互概念的功能。

本质上，它通过添加回调函数使开发者能够在智能体交互过程中请求用户输入，同时也支持执行任何程序化操作。

用于向用户展示函数调用生成的数据，并请求其输入以返回交互的函数。

In [ ]:

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]}\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" )

仅需接收者和问候消息的简单函数。

In [ ]:

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: """ 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)

In [ ]:

hello_tool.to_langchain_tool

hello_tool.to_langchain_tool

Out[ ]:

<bound method FunctionTool.to_langchain_tool of <llama_index.core.tools.function_tool.FunctionTool object at 0x7f7da9fa5670>>

In [ ]:

llm = OpenAI()
agent = OpenAIAgent.from_tools([hello_tool])

llm = OpenAI() agent = OpenAIAgent.from_tools([hello_tool])

In [ ]:

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

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

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

In [ ]:

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

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

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