问题：

Microsoft Bot是否在WebChat中显示不必要的重复消息？

端木存
2023-03-14

当用户第一次访问我的聊天室时，他们会收到欢迎信息，并立即被要求提供他们的名字。一旦用户输入他们的名字，欢迎信息就会显示，并再次显示输入他们名字的文本提示。只有在他们第二次输入他们的名字后，机器人才会进入下一个关于他们姓氏的问题。

此外，当用户最终在第一次聊天中输入他们的名字和姓氏时，他们会再次回到同一个聊天，欢迎消息

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

// 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); 
})

应用程序首次运行时，应向用户显示欢迎信息并询问其名字。一旦他们输入了他们的名字，机器人就应该立即转到下一个关于他们姓氏的问题，在用户回答之后，机器人应该结束对话。

当用户输入他们的第一个

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;
  });

这些截图是在dev.botframework中拍摄的。com测试窗口。然而，同样的行为也适用于我使用WebChat的web应用程序。

你能帮我解决这个问题吗？

对那些仍然有问题的人来说

在Web通道和机器人之间建立第一次对话时，会引发ConversationUpdate活动两次。一个由用户，另一个由信道，因此我们得到两次欢迎消息。我们需要确保我们为用户提出的活动发送了欢迎消息。在这里找到工作代码

实际上，当bot连接器第一次连接到bot服务器时，bot首先加入会话，因此将为您的bot触发conversationUpdate事件，其中不包含会话。用户数据对象。

一旦用户在bot webchat中输入了一些信息，用户就会有第二次会话更新。此时，bot在会话包含会话的会话更新事件中开始执行'\'。用户数据对象。

您可以添加以下中间件来检测此问题：

bot.use({
    receive: function (event, next) {
        console.log(event)
        next();
    },
    send: function (event, next) {
        console.log(event)
        next();
    }
});

不幸的是，当webchat初始化时，我找不到一种方法让bot为用户触发conversationUpdate。

您可以利用网站上的webchat js sdk和反向通道机制来实现您的要求。

//定义用户

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"));

bot.on('event',(event)=>{
  console.log(event)
  if(event.name==='ConversationUpdate'){
    bot.beginDialog(event.address, '/');
  }
})
