_@ctx.room.on("participant_connected") does not work_

Thanks for reaching out, 郭朋. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

以下是我的代码示例，其中 ctx 是 JobContext def *on_participant_connected*(participant): logger.*info*(f"新参与者加入: {participant.identity}") ctx.room.on("participant_connected", on_participant_connected)

Thank you for sharing your code snippet. Based on the provided information, here is an example of using

ctx.room.on("participant_connected")

in a JobContext:

@ctx.room.on("participant_connected")
def on_participant_connected(participant):
    <http://logger.info|logger.info>(f"New participant joined: {participant.identity}")
    if not "sip_" in participant.identity:
        return

    # Example of additional logic
    task = participant._info.attributes.get("task")
    <http://logger.info|logger.info>(f"Task: {task}")

    # Initialize user data and start session (if applicable)
    # ...

Ensure that your

ctx

object is properly initialized and that the

room

attribute is accessible. If the issue persists, please verify the context setup or share more details about the error you are encountering. Sources: Building an Automated IVR Menu Caller | LiveKit Docs

这些代码要放在await ctx.connect()之后，还是之前，我想知道它的具体位置

根据文档，您应该在调用

ctx.connect()

之前注册事件监听器，例如 `ctx.room.on("participant_connected", handler)`。这样可以确保在连接到房间后不会错过任何事件。 以下是一个示例：

room = Room()
# 在连接到房间之前监听事件
@room.on("participant_connected")
def on_participant_connected(participant):
    print(f"Participant connected: {participant.identity}")

await room.connect("<ws://localhost:7880>", "your_token")

请确保在连接之前正确设置事件监听器。如果还有其他问题，请随时告诉我！ Sources: livekit.rtc.room API documentation
