node.js - Bot框架:多步瀑布

我想向机器人发送与此类似的内容

"[Person] wants to meet at [Place] at [Date]"

但是，如果该人错过了一些信息，我希望该机器人逐步要求它。

例如，如果某人写道：

"Let's meet!"

机器人会提出一系列问题来满足所有数据要求。就像是：


我要见谁？
他们应该在哪里见面？
什么日期和时间？


如果对方提出以下要求：

"Alex would like to meet tomorrow"

然后，机器人只会问

"Where should they meet?"

一旦所有必需的数据完成，它将发送如下响应：

"Great, I will meet [Person] in [Location] at [DateTime]"

我一直在尝试这种运气不好的方法，并收到“对session.EndDialog（）的调用过多”错误：

dialog.on('Meeting', [
    function (session, results, next) {
        var person = builder.EntityRecognizer.findEntity(results.entities, 'Person');
        if(!person){
            builder.Prompts.text(session, prompts.meetingPersonMissing);
        } else {
            next({ response: {
                    person: person.entity
                }
            });
        }
    },
    function (session, results, next) {
        var location = builder.EntityRecognizer.findEntity(results.entities, 'location');
        if(!location){
            builder.Prompts.text(session, prompts.meetingLocationMissing);
        } else {
            // Pass title to next step.
            next({ response: {
                    person: results.person,
                    location: location.entity
                }
            });
        }
    },
    function (session, results, next) {
        var time = builder.EntityRecognizer.findEntity(results.entities, 'builtin.datetime.date');
        if(!time){
            builder.Prompts.text(session, prompts.meetingTimeMissing);
        } else {
            next({ response: {
                    person: results.person,
                    location: results.location,
                    time: time.entity
                }
            });
        }
    },
    function (session, results) {
        if (results.response) {
           session.send(prompts.meetingSubmited);
        } else {
            session.send(prompts.canceled);
        }
    }
]);

尝试2失败（不再从“ next（）”传递数据）。这导致相同的EndDialog错误

dialog.on('Meeting', [
    function (session, results, next) {
        var person = builder.EntityRecognizer.findEntity(results.entities, 'Person');
        var location = builder.EntityRecognizer.findEntity(results.entities, 'location');
        var time = builder.EntityRecognizer.findEntity(results.entities, 'builtin.datetime');

        session.messageData = {
            person: person || null,
            location: location || null,
            time: time || null
        }

        if(!session.messageData.person){
            builder.Prompts.text(session.messageData.person, prompts.meetingPersonMissing);
        } else {
            next();
        }
    },
    function (session, results, next) {
        if(!session.messageData.location){
            builder.Prompts.text(session.messageData.location, prompts.meetingLocationMissing);
        } else {
            next();
        }
    },
    function (session, results, next) {
        if(!session.messageData.time){
            builder.Prompts.text(session.messageData.time, prompts.meetingTimeMissing);
        } else {
            next();
        }
    },
    function (session, results) {
        debugger;
        if (results.response) {
           session.send('Meeting scheduled');
        } else {
            session.send(prompts.canceled);
        }
    }
]);

更新＃3：在此版本中，如果语音不包含任何相关实体，则效果很好。例如“我们可以见面吗？”工作良好。

这个版本的问题是当我尝试“我们明天见面吗？”时。明天已成功标识为日期时间实体，但是一旦它在此块中触到next()：

 function getDate(session, results){
    session.dialogData.topic = results.response;

    if(session.dialogData.date){
        next();
     }else{
        builder.Prompts.time(session, "What date would you like to meet?");
     }

}

它失败并给我相同的Too many calls to to session.EndDialog()问题

dialog.on('Meeting', [meetingQuery, getDate, getTime, respondMeeting]);

function meetingQuery(session, results){

    if (results.response) {
        session.dialogData.date = builder.EntityRecognizer.resolveTime([results.response]);
    }


    session.userData = {
        person: session.message.from.name
    }

    builder.Prompts.text(session, "Hi "+ session.userData.person +"!\n\n What is the meeting in reference too?");

}

function getDate(session, results){
    session.dialogData.topic = results.response;

    if(session.dialogData.date){
        next();
     }else{
        builder.Prompts.time(session, "What date would you like to meet?");
     }

}

function getTime(session, results){
    if (results.response) {
        session.dialogData.date = builder.EntityRecognizer.resolveTime([results.response]);
    }


     if(session.dialogData.time){
        next();
     }else{
        builder.Prompts.choice(session, "Your professor has the follow times availeble?", ["1pm", "2pm", "3pm"]);
     }
}

function respondMeeting(session, results){
    var time = results.response;
    session.send("Your meeting has been schedueld for " + session.dialogData.date + " at " + time.entity + ". Check your email for the invite.");
}

最佳答案

试试这个，它可以在我的机器人上运行。

dialog.on('QuieroQueMeLlamen', [
    function (session, args) {
    	var Telefono = builder.EntityRecognizer.findEntity(args.entities, 'Usuario::Telefono');

        if(!Telefono){
        	builder.Prompts.number(session, "Dame un número telefónico donde pueda llamarte una de nuestras enfermeras (sin espacios ni caracteres: ej: 3206907529)");
        }

    },
    function (session, results) {
        if (results.response) {
        	//IF STRLEN es un celular entonces:
            session.send("Te estamos llamando al número %s, por favor contesta", results.response);
        }
    }
]);
