Bot在Microsoft Teams中的行为不同

Question

I've deployed my Bot to Webchat, Skype and MS Teams.

In OnTurnAsync method I check, if the user input begins with bnr then I call a specific method.

if (turnContext.Activity.Text.ToLower().StartsWith("bnr"))
{
    string msg = RequestHandler.BnrCaller(turnContext.Activity.Text);
    await turnContext.SendActivityAsync(msg);
    return;
}

It works fine with Skype and Webchat but with teams it does not work 100%, It works just sometimes.

[Edit]

I found out, that it does not work if I copied the input into the input field but when I type it, it works fine!

Answer 1

The Messages coming from the Teams are having a different structure. The message text begins with the words <at>...</at> . You need to delete this beginning in a Middleware component, etc. Try to look at your incoming messages through NGROK at localhost:4040 in your web browser.

Answer 2

So, I found out the issue by dint of app-insights.

I've added a middleware , which logs the request body into app-insights and just realized, that when I copy/paste a message like: "Hello", it would be logged in app-insights as something like this "\\r\\n\\n\\rHello\\r\\n\\n\\r\\n". When I type it, it would be logged just fine. So I jsut remove these symboles from the request and it works!
