Microsoft QnA maker - 欢迎消息循环

Question

我正在尝试实现类似于在这个主题上所做的事情 Begin Dialog with QnA Maker Bot Framework recognizer (Node JS)

该建议的工作原理是让机器人首先发送欢迎消息，然后等待问题。 然而，机器人现在说'Hj！我有什么可以帮助你的吗？”，等待问题，然后再次回到欢迎状态。

有点像

答：嗨！我怎么帮你？ 问：汽车维修号码是多少 A: 拨打 500-XXXX 等。 问：假期我应该联系谁？ 答：嗨！有什么可以帮助你的吗？

我玩了 beginDialog，结束对话，替换对话.. 但是没有运气。

这是最新的代码。

bot.dialog('/', [
    function (session ) {
          session.beginDialog('/welcome');
        }, 
    function (session)  {
        session.beginDialog('/qna');
}
]) ;



bot.dialog('/welcome', [
        function (session) {
            // Send a greeting and show help.
            builder.Prompts.text(session, "Hi! How can I help you?");
            //  session.endDialog();
        }
    ]);


bot.dialog('/qna',  basicQnAMakerDialog   ) ;

下面的代码示例展示了如何侦听新用户连接到机器人时触发的 conversationUpdate 事件。又名“欢迎信息”：

// Listen for 'conversationUpdate' event to detect members joining conversation.
bot.on('conversationUpdate', function (message) {
    if (message.membersAdded) {
        message.membersAdded.forEach(function (identity) {
            if (identity.id == message.address.bot.id) {
                // Bot is joining conversation
                // - For WebChat channel you'll get this on page load.
                var reply = new builder.Message()
                        .address(message.address)
                        .text("Welcome to my page");
                bot.send(reply);
            } else {
                // User is joining conversation
                // - For WebChat channel this will be sent when user sends first message.
                // - When a user joins a conversation the address.user field is often for
                //   essentially a system account so to ensure we're targeting the right 
                //   user we can tweek the address object to reference the joining user.
                // - If we wanted to send a private message to teh joining user we could
                //   delete the address.conversation field from the cloned address.
                var address = Object.create(message.address);
                address.user = identity;
                var reply = new builder.Message()
                        .address(address)
                        .text("Hello %s", identity.name);
                bot.send(reply);
            }
        });
    }
});
