如何留在由 LUIS nodejs 触发的对话框中

Question

我正在使用 MS 的 Bot Framework 玩一些聊天机器人。 我创建了一个用来预订航班的软件，它集成了 LUIS。

我的问题是：一旦进入由 LUIS 触发的航班预订对话框，我想检查有关航班的所有信息是否由用户提供（出发城市、到达城市、日期、航空公司...） .所以如果我错过了一个信息，例如出发城市，机器人会问“你能给我出发城市吗？” qnd 如果我写“来自伦敦”，LUIS 会将其检测为新的航班预订并触发另一个对话。但我显然希望它留在对话框中！

这是到目前为止的对话代码，以防万一缺少出发城市：

// Main dialog with LUIS
bot.dialog('FlightBookingDialog', [
function (session, args, next) {
    // Resolve and store any entity passed from LUIS.
    var intent = args.intent;

    session.dialogData.airline = builder.EntityRecognizer.findEntity(intent.entities, 'Airline');
    session.dialogData.class = builder.EntityRecognizer.findEntity(intent.entities, 'Class');
    session.dialogData.date_time = builder.EntityRecognizer.findEntity(intent.entities, 'builtin.datetimeV2');
    session.dialogData.departure = builder.EntityRecognizer.findEntity(intent.entities, 'Departure');
    session.dialogData.destination = builder.EntityRecognizer.findEntity(intent.entities, 'Destination');
    session.dialogData.number_tickets = builder.EntityRecognizer.findEntity(intent.entities, 'number');

    session.send("I see you want to travel, great !");

    if(!session.dialogData.departure) {
        builder.Prompts.text(session, "Can you specify me a departure city please ?");
    } else {
        next();
    }
},
function (session, args, results, next) {
    if (results.response) {
        builder.LuisRecognizer.recognize(session.message.text, luisModelUrl,
            function(err, intents, entities) {
                if(entities) {
                    var departure = builder.EntityRecognizer.findEntity(intents.entities, 'Departure');
                    if (departure) {
                        session.dialogData.departure = departure;
                    }
                }
            }
       );
    };

    session.send("Good !");
},

]).triggerAction({ 匹配：'FlightBooking' });

如果我理解正确，我认为您可以更新代码以具有多个匹配项。从此documentation page 代码可能会更新为如下所示：

var intents = new builder.IntentDialog({ recognizers: [recognizer] })
.matches('Greeting', (session) => {
    session.send('You reached Greeting intent, you said \'%s\'.', session.message.text);
})
.matches('Note.Create', [(session, args, next) => {
        // Resolve and store any Note.Title entity passed from LUIS.
        var intent = args.intent;
        var title = builder.EntityRecognizer.findEntity(intent.entities, 'Note.Title');

        var note = session.dialogData.note = {
          title: title ? title.entity : null,
        };

        // Prompt for title
        if (!note.title) {
            builder.Prompts.text(session, 'What would you like to call your note?');
        } else {
            next();
        }
    },
    (session, results, next) => {
        var note = session.dialogData.note;
        if (results.response) {
            note.title = results.response;
        }

        // Prompt for the text of the note
        if (!note.text) {
            builder.Prompts.text(session, 'What would you like to say in your note?');
        } else {
            next();
        }
    },
    (session, results) => {
        var note = session.dialogData.note;
        if (results.response) {
            note.text = results.response;
        }

        // If the object for storing notes in session.userData doesn't exist yet, initialize it
        if (!session.userData.notes) {
            session.userData.notes = {};
            console.log("initializing session.userData.notes in CreateNote dialog");
        }
        // Save notes in the notes object
        session.userData.notes[note.title] = note;

        // Send confirmation to user
        session.endDialog('Creating note named "%s" with text "%s"',
            note.title, note.text);
    }])

请注意，在机器人拥有处理请求所需的所有信息之前，没有endDialog 方法。

希望能帮助或至少让您走上正确的道路！

我在这里找到了解决方案： https://github.com/Microsoft/BotFramework-Samples/tree/master/docs-samples/Node/basics-naturalLanguage

他们正是在谈论我的问题，我将其发布在这里，以便处于相同情况的人可以看到它。

你必须去IntentDialog部分，Ctrl+F它。
