Microsoft Bot在WebChat中显示不必要的重复消息？

时间：2018-01-12 16:35:16

标签： node.js botframework direct-line-botframework

当用户第一次访问我的聊天时会收到欢迎消息，并立即要求他们提供他们的名字。一旦用户输入他们的名字，欢迎消息就会再次显示他们的名字的文本提示。只有在他们第二次输入他们的名字后，机器人才会转到关于他们姓氏的下一个问题。

此外，当用户最终在第一次聊天中输入他们的姓名并再次回到同一个聊天时，欢迎消息＆amp;显示名字提示，仅当用户提供某些输入时，bot会发送欢迎回复消息。

这是重现此问题所需的最少代码。     让restify = require（＆＃39; restify＆＃39;）;     让builder = require（＆＃39; botbuilder＆＃39;）; 

// Setup Restify Server
let server = restify.createServer();

let connector = new builder.ChatConnector({
    appId: process.env.MICROSOFT_APP_ID,
    appPassword: process.env.MICROSOFT_APP_PASSWORD
});

server.post('/api/messages', connector.listen());

let bot = new builder.UniversalBot(connector);

// Define default Dialog
bot.dialog('/', [
  function (session) {
    if (!session.userData.firstName) {
      // firstName used as a flag to assess whether the user is coming back
      // or new user - we can use it because the very first dialog is asking them
      // for their first name.
      session.send("Welcome!");
    } else {
      session.send("Welcome back %s!", session.userData.firstName);
    }

    session.beginDialog('mainConversationFlow');
  }
])

bot.dialog('mainConversationFlow', [
    function(session, args, next) {
      if (!session.userData.firstName)
        session.beginDialog('getFirstName');
      else 
        next();
    },
    function(session, args, next) {
      if(!session.userData.lastName) 
        session.beginDialog('getLastName');
      else
        next();
    }, 
    function(session, args, next) {
      session.endConversation('The End');
    }
])

bot.dialog('getFirstName', [
  function(session, args) {
    let msg = "What's your first name?";

    builder.Prompts.text(session, msg);
  },
  function(session, results) {
    session.userData.firstName = results.response.trim();
    session.endDialog();
  }
])

bot.dialog('getLastName', [
  function(session, args) {
    let msg = builder.Message.composePrompt(session,
      ["Hi %s, what's your last name?"], session.userData.firstName);

    builder.Prompts.text(session, msg);
  },
  function(session, results) {
    session.userData.lastName = results.response.trim();

    session.endDialog();
  }
])

bot.on('conversationUpdate', function (message) {
    if (message.membersAdded) {
        message.membersAdded.forEach(function (identity) {
            if (identity.id === message.address.bot.id) {
                bot.beginDialog(message.address, '/');
            }
        });
    }
})

server.listen(process.env.port || process.env.PORT || 3978, function () {
   console.log('%s listening to %s', server.name, server.url); 
})

首次运行应用程序的用户应显示欢迎消息并询问他们的名字。一旦他们输入了他们的名字，机器人就应该立即转到关于他们姓氏的下一个问题，并在用户回答该机器人应该结束对话之后。

当用户输入他们的第一个＆amp;姓氏和他们回来，机器人应该只显示欢迎回复消息和结束对话。

这是我使用BotFramework-WebChat：

的客户端代码片段 
let directLineSecret = 'mysecret';
let directLineSpecUrl = 'https://docs.botframework.com/en-us/restapi/directline3/swagger.json';

BotChat.App({
  directLine: {secret: directLineSecret},
  user: { id: localStorage.getItem('email')},
  bot: { id: 'testbot' },
  resize: 'detect'
}, this.botChatContainer.nativeElement);

let directLineClient = rp(directLineSpecUrl)
  .then(function(spec) {
    return new Swagger({
      spec: JSON.parse(spec.trim()),
      usePromise: true
    });
  })
  .then(function(client) {
    return rp({
      url: 'https://directline.botframework.com/v3/directline/tokens/generate',
      method: 'POST',
      headers: {
        'Authorization': 'Bearer ' + directLineSecret
      },
      json: true
    }).then(function(response) {
      let token = response.token;
      client.clientAuthorizations.add('AuthorizationBotConnector', new Swagger.ApiKeyAuthorization('Authorization', 'Bearer ' + token, 'header'));
      return client;
    });
  })
  .catch(function(err) {
    console.error('Error initializing DirectLine client', err);
    throw err;
  });

First time chat is initialized This happens when user comes back

这些截图是在dev.botframework.com测试窗口中拍摄的。但是，在我使用WebChat的Web应用程序中也会出现相同的行为。

你能帮我解决这个问题吗？

})

2 个答案:

答案 0 :(得分：2)

实际上，当僵尸网络连接器首次连接到僵尸服务器时，僵尸程序首先加入对话，因此将为您的僵尸程序触发:g/profile/d 事件，而不包含conversationUpdate对象。< / p>

一旦用户在机器人网络聊天中输入了某些信息，那么用户将会有第二个session.userData。此时，在conversationUpdate事件内的bot beginDialog '\'会话中包含conversationUpdate个对象。

您可以添加以下中间件来检测此问题：

session.userData

不幸的是，在网络聊天初始化时，我找不到让bot触发bot.use({ receive: function (event, next) { console.log(event) next(); }, send: function (event, next) { console.log(event) next(); } }); 的方法。

更新

您可以利用webchat js sdk on website和the backchannel mechanism来满足您的要求。

网站客户端：

//定义用户

conversationUpdate

bot服务器：

const user = {id:'userid',name:'username'};

const botConnection = new BotChat.DirectLine({
        domain: params['domain'],
        secret: '<secrect>',
        webSocket: params['webSocket'] && params['webSocket'] === 'true' // defaults to true
      });
botConnection .postActivity({ type: "event", from: user, name: "ConversationUpdate", value: "" }) .subscribe(id => console.log("Conversation updated"));
BotChat.App({
    botConnection: botConnection,
    bot: bot,
    user: user,
    resize: 'detect'
}, document.getElementById("BotChatGoesHere"));

答案 1 :(得分：0)

在网络频道与漫游器之间建立第一个对话时，ConversationUpdate活动将引发两次。一个由用户，另一个由频道，因此我们收到两次欢迎消息。我们需要确保针对用户提出的活动发送欢迎消息。 Find the working code here
