我无法从Microsoft Teams bot向另一个用户发送消息

Question

It is impossible to send a message to another user from the bot in Microsoft Teams. It constantly sends messages to me although all the parameters are passed from the database.

Anton: name of db table

async def create_reply_activity2(text) -> Activity:
    return Activity(
        type=ActivityTypes.message,
        channel_id=Anton.query.all()[0],
        conversation=Anton.query.all()[1],
        recipient=Anton.query.all()[3],
        from_property=Anton.query.all()[2],
        text=text,
        service_url=Anton.query.all()[4])

resp = await create_reply_activity2("yo.")
    await context.send_activity(resp)

Answer 1

What you want to do is send a proactive message . Ordinarily, bots function by only sending a message to a user when that user sends a message to the bot in what's called a turn. Since you want to send a message to a user outside of a turn in response to something other than that user messaging the bot, the message is considered proactive. Therefore, you shouldn't be trying to send a message using the turn context because that context applies to the turn that's between the bot and the user who messaged it.

Instead of sending a message like this:

await context.send_activity(resp)

You should be sending a message like this:

credentials = MicrosoftAppCredentials(APP_ID, APP_PASSWORD)
connector = ConnectorClient(credentials, base_url=context.activity.service_url)
connector.conversations.send_to_conversation(Anton.query.all()[1].id, resp)

Of course, you should be storing the result of the query so you don't have to be running the same query over and over again.
