node.js - Azure Bot NodeJS 等待其他对话框完成

Question

我目前正在使用 Azure 的 Bot 服务构建一个聊天机器人。我使用 NLU-Bot，与 waterfall 流混合，因为根据我想要获取一些特定信息的意图。 因此我匹配 intent1 并想要

var intents = new builder.IntentDialog({ recognizers: [recognizer] })
.matches('intent1', (session, args, results) =>{

    session.beginDialog("getRequiredInformations");
    session.send("I received your information");
})

bot.dialog('getRequiredInformations', [
    (session) =>{       
        var levels = ['Beginner', 'Intermediate', 'Expert'];
        builder.Prompts.choice(session, "What's your level ?", levels, { listStyle: builder.ListStyle.button, maxRetries: 0 });
    },
    (session, results) => {
        session.conversationData.level = results.response.entity;
    }
]);

我想要做的是等到我们收到来自 getRequiredInformations 对话框的答案，然后继续使用包含已识别意图的原始对话框。上面的代码 session.send("I receive your information"); 在用户输入答案之前发送。

我也尝试过使用 bot.beginDialogAction('getRequiredInformations', 'getRequiredInformations'); 但我认为不可能在对话框中调用它。

我怎样才能实现这一目标？

发现您的代码片段存在多处错误，请引用以下修改:

bot.dialog('intent1', [(session, args, next) => {
    session.beginDialog("getRequiredInformations");
}, (session, args, next) => {
    session.send("I received your information");
    session.send(session.conversationData.level)
}]).triggerAction({
    matches: 'intent1'
})

bot.dialog('getRequiredInformations', [
    (session) => {
        var levels = ['Beginner', 'Intermediate', 'Expert'];
        builder.Prompts.choice(session, "What's your level ?", levels, {
            listStyle: builder.ListStyle.button,
            maxRetries: 0
        });
    },
    (session, results) => {
        session.conversationData.level = results.response.entity;
        session.endDialog();
    }
]);

But this means there is not really an opportunity to wait for the dialog to finish like a callback or anything, I need to do this with a waterfall?

如果我理解正确，您可以尝试使用以下代码片段仅在堆栈中没有对话框的情况下启用 luis 识别器。

var recognizer = new builder.LuisRecognizer(luisAppUrl)
 .onEnabled(function (context, callback) {
     var enabled = context.dialogStack().length == 0;
     callback(null, enabled);
 });
