在MS团队中与群组聊天中的机器人对话

Question

我的问题是在Microsoft Teams的群聊中处理与机器人的对话。我正在尝试MS教程中的基本示例：

var builder = require('botbuilder');
var restify = require('restify');

//=========================================================
// Bot Setup
//=========================================================

// Setup Restify Server
var server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function () {
   console.log('%s listening to %s', server.name, server.url); 
});

// Create chat bot
var connector = new builder.ChatConnector({
    appId: process.env.MICROSOFT_APP_ID,
    appPassword: process.env.MICROSOFT_APP_PASSWORD
});
var bot = new builder.UniversalBot(connector);
server.post('/api/messages', connector.listen());

//=========================================================
// Bots Dialogs
//=========================================================

var intents = new builder.IntentDialog();
bot.dialog('/', intents);

intents.matches(/^change name/i, [
    function (session) {
        session.beginDialog('/profile');
    },
    function (session, results) {
        session.send('Ok... Changed your name to %s', session.userData.name);
    }
]);

intents.onDefault([
    function (session, args, next) {
        if (!session.userData.name) {
            session.beginDialog('/profile');
        } else {
            next();
        }
    },
    function (session, results) {
        session.send('Hello %s!', session.userData.name);
    }
]);

bot.dialog('/profile', [
    function (session) {
        builder.Prompts.text(session, 'Hi! What is your name?');
    },
    function (session, results) {
        session.userData.name = results.response;
        session.endDialog();
    }
]);

这个简单的对话框在一对一聊天中很有用：https://screencast.com/t/VgjlxYMea
但在群聊中，识别意图存在问题：https://screencast.com/t/f7JAr7HFAY7

我的第一个想法是，提到机器人我应该更新意图的模式，从/^change name/i到/.*change name/i，显然机器人开始认识到意图：https://screencast.com/t/i66rDQj0pC ...但是进入对话框仍然没有运气。
