Bot Framework：多步瀑布

Question

我想发送一个类似这样的机器人

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

但是，如果此人遗漏了某些信息，我希望机器人逐条询问。

例如，如果一个人写：

"Let's meet!"

机器人会提出一系列问题来满足所有数据要求。比如：

1. 我会见谁？
2. 他们应该在哪里见面？
3. 什么日期和时间？

如果对方问这样的问题：

"Alex would like to meet tomorrow"

那么机器人只会问

"Where should they meet?"

一旦完成所有必需的数据，它将发送如下响应：

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

我一直在尝试这样的方法，但运气不佳并收到“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);
        }
    }
]);

不成功的尝试 #2（不再从 'next()' 传递数据）。这会导致相同的 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：在这个版本中，如果话语不包含任何相关实体，它会很好地工作。例如“我们可以见面吗？”工作正常。

这个版本的问题是当我尝试“我们明天可以见面吗？”时。 Tomorrow 被成功识别为日期时间实体，但是一旦它在此块中点击 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?");   
     }

}

它失败并给了我同样的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.");
}

Answer 1

试试这个，它适用于我的机器人。

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);
        } 
    }
]);

Answer 2

您不应将参数传递给 next() 函数，而应使用 session.YOUVARIABLES 通过瀑布存储数据。

类似：

function (session, results, next) {
    var person = builder.EntityRecognizer.findEntity(results.entities, 'Person');
    if(!person){
        builder.Prompts.text(session, prompts.meetingPersonMissing); 
    } else {
        session.person = person.entity
        next();
    }
}

Answer 3

我认为你应该访问

results.response.person 

而不是

results.person 

同样适用于这个瀑布的其他闭包。
