无法从luis.ai到bot框架获得响应，而是得到错误

Question

我开始在node.js中开发bot框架，并在我的nlp中使用luis.ai。参考node.js僵尸框架中关于azure的文档，我在app.js中进行了代码更改。但是，在在线编辑器中运行代码时，我会得到以下错误。

信息重启服务器..。信息点击http://firstbot2-b893.azurewebsites.net打开你的网站重新注册收听http://undefined:undefined

另外，一个新的浏览器窗口打开时会出现以下错误.

代码"ResourceNotFound“消息"/不存在”

请在下面找到app.js和package.json代码..。

app.js

var restify = require('restify');
var builder = require('botbuilder');
var botbuilder_azure = require("botbuilder-azure");

// Setup Restify Server
var server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function () {
   console.log('%s listening to %s', server.name, server.url); 
});

// Create chat connector for communicating with the Bot Framework Service
var connector = new builder.ChatConnector({
    appId: process.env.MicrosoftAppId,
    appPassword: process.env.MicrosoftAppPassword,
    openIdMetadata: process.env.BotOpenIdMetadata 
});

// Listen for messages from users 
server.post('/api/messages', connector.listen());

var tableName = 'botdata';
var azureTableClient = new botbuilder_azure.AzureTableClient(tableName, process.env['AzureWebJobsStorage']);
var tableStorage = new botbuilder_azure.AzureBotStorage({ gzipData: false }, azureTableClient);

// Create your bot with a function to receive messages from the user
//var bot = new builder.UniversalBot(connector);
// Create your bot with a function to receive messages from the user
// This default message handler is invoked if the user's utterance doesn't
// match any intents handled by other dialogs.
var bot = new builder.UniversalBot(connector, function (session, args) {
    session.send('You reached the default message handler. You said \'%s\'.', session.message.text);
});
bot.set('storage', tableStorage);

// Make sure you add code to validate these fields
var luisAppId = process.env.LuisAppId;
var luisAPIKey = process.env.LuisAPIKey;
var luisAPIHostName = process.env.LuisAPIHostName || 'westus.api.cognitive.microsoft.com';

const LuisModelUrl = 'https://' + luisAPIHostName + '/luis/v2.0/apps/' + luisAppId + '&subscription-key=' + luisAPIKey;


// Main dialog with LUIS
var recognizer = new builder.LuisRecognizer(LuisModelUrl);
// Add the recognizer to the bot
bot.recognizer(recognizer);

var intents = new builder.IntentDialog({ recognizers: [recognizer] })
.matches('Greeting', (session) => {
    session.send('You reached Greeting intent, you said \'%s\'.', session.message.text);
})
.matches('Help', (session) => {
    session.send('You reached Help intent, you said \'%s\'.', session.message.text);
})
.matches('Cancel', (session) => {
    session.send('You reached Cancel intent, you said \'%s\'.', session.message.text);
})
.matches('Reports', (session) => {
    session.send('You reached Reports intent, you said \'%s\'.', session.message.text);
})
.onDefault((session) => {
    session.send('Sorry, I did not understand \'%s\'.', session.message.text);
});

//bot.dialog('/', intents);

Answer 1

是否有理由对此作出评论：

//bot.dialog('/', intents);

似乎您需要在某个地方定义对话框来侦听，并与"/“没有找到资源的错误进行匹配。

Answer 2

var bot = new builder.UniversalBot(connector, function (session, args) {
    session.send('You reached the default message handler. You said \'%s\'.', 
        session.message.text);
});

第二个参数算作根对话框('/')，这就是为什么您收到了有关已经存在的对话框的错误消息。

您还将LuisRecognizer插入到bot级别，然后插入到IntentDialog中

// Main dialog with LUIS
var recognizer = new builder.LuisRecognizer(LuisModelUrl);
// Add the recognizer to the bot
bot.recognizer(recognizer);

var intents = new builder.IntentDialog({ recognizers: [recognizer] })

您应该只使用其中一种或另一种，特别是在开始时和仅使用其中一种创建的LuisRecognizer时。

我建议将var bot行更改为：

var bot = new builder.UniversalBot(connector);

然后，只在根对话框中使用您的IntentDialog，取消对以下行的注释：

//bot.dialog('/', intents);
