我想知道是否可以使用QnA Maker识别器在与机器人进行聊天的开始时传递欢迎消息"，而模型不会将其识别为要发送给模型的消息.我正在使用最新的Node.js API.

I was wondering if one can pass a "Welcome Message" on the beginning of a chat with a bot using QnA Maker recognizer without the model recognizing it as message to send to the model. I'm using the latest Node.js API.

var intents = new builder_cognitiveservices.QnAMakerDialog({ recognizers: [recognizer], defaultMessage: 'Sorry. I didnt understand', qnaThreshold: 0.3} ); bot.dialog('/', [ function(session){ session.beginDialog('welcome'); }, function(session){ session.beginDialog('dialog'); } ]); bot.dialog('welcome', [ function (session) { // Send a greeting and show help. session.send("Hi! How can I help you?"); session.endDialog(); } ]); bot.dialog('dialog', intents);

就像这样，我的机器人正在发送session.send("Hi! How can I help you?")； QnA模型并回答对不起.我不明白".

Like this, my bot is sending the session.send("Hi! How can I help you?"); to the QnA Model and replying "Sorry. I didnt understand".

使用 LUIS ，我仅使用QnAMakerDialog时就没有此问题.

With LUIS I don't have this issue only with the QnAMakerDialog.

有人知道如何解决吗?

推荐答案

我认为这段代码可以为您提供所需的行为.

I think this code gives you the behavior you're looking for.

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

我认为这是失败的原因，因为session.send后跟session.endDialog并不是在等待用户，而是失败了.

I think it's falling through because session.send followed by session.endDialog is not waiting for the user and it falls through.
