其实，

  1. 我使用 PubNub 的聊天引擎创建了聊天应用程序，但我无法在同一 channel 上实现两个用户的私有(private)聊天。这意味着我有一个管理员和多个其他用户，这样他们就可以与管理员聊天，管理员可以与其他用户聊天，但是，同一 channel 的其他用户不应该看到一个用户和管理员聊天，即我想在两个用户之间实现私有(private)聊天同一个 channel 。所以请任何人使用聊天引擎引用或示例私有(private)聊天源代码。

  2. 第二期是用gr显示头像

PubNub的头像插件，这也是我无法显示的。请也分享这个。

这是我的 Javascript 文件:

        //create a new instance of ChatEngine
        ChatEngine = ChatEngineCore.create({
            publishKey: key
            subscribeKey: key
        },{ debug: true});

        // create a bucket to store our ChatEngine Chat object
        let myChat;

        // create a bucket to store 
        let me;

        // these function is used for typing indicator
        let sendmsg = function () {};
        let keypress = function () {};

        // create an optional config object to increase the default 
            timeout from 1000ms
        let typingconfig = { timeout: 1000 };

        // compile handlebars templates and store them for use later
        let peopleTemplate = Handlebars.compile($("#person- 
           template").html());
     let meTemplate = Handlebars.compile($("#message-template").html());
    let userTemplate = Handlebars.compile($("#message-response- 
           template").html());

        let searchconfig = { prop: 'state.full', caseSensitive: false }
        // this is our main function that starts our chat app
        const init = () => {
        ChatEngine.connect ('email', { username: 'name', full:'K' },
        'auth-key');

        // when ChatEngine is booted, it returns your new User as 
          `data.me`
        here my function is called by the pubnub

        ChatEngine.on('$.ready', function(data) {
        // store my new user as `me`
        me = data.me;
        //create a new ChatEngine Chat and I am connecting to chatenging
       using this option.
        myChat = new ChatEngine.Chat('chat-engine-server',true);      

        // here i am updating the the state of the user
        me.update(
        {
         full:'John Doe', 
         username: 'John',
         uuid: 'johndoe@gmail.com'
        });
        //starting private chat logic
        // this is what I wrote the code that use to create the privat 
         chat 

       myChat.invite(' invited email');

        me.direct.on('$.invite', (payload) => {
        console.log("invited user");    
        let secretChat = new ChatEngine.Chat(payload.data.channel);            
        document.getElementById("punlicLog").style.display = 'none';
        document.getElementById("privateLog").style.display = 'inline';
        document.getElementById("message-to-send").style.display='none';
        document.getElementById("private-message-to-send").
               style.display='inline';            
        here I am sending message to this payload
        secretChat.on('message', (payload) => {
          console.log(payload);
      // using this methd i am rendering private message
          privaterenderMessage(payload);
          });            
          //$('#privateLog').append("Now you are in a Private Chat with " 
          + globalUsr );            

       // this is take the message from the input box to send
        $("#privateMessage").keypress(function (event) {
        if (event.which == 13) {
        secretChat.emit('message', {
        text: $('#privateMessage').val()
         });
        $("#privateMessage").val('');
        event.preventDefault();
        }
        }); });

         //ending private chat message

        // this part belong to the pic
        console.log("before gravator'''''''''''''''''': ")  
        user = new ChatEngine.User(me.state.username, {email: 
         me.state.uuid});
                    console.log(" full name : "+me.state.full); 
                    $("#pic").attr("src", user.state.gravatar);

          myChat.on('message', (message) => {
                  console.log("message send mychat.on() method to send 
                      ");
                  renderMessage(message);
              });
              // when a user comes online, render them in the online list
              });

              bind our send button and return key to send message
              $('#sendMessage').on('submit', sendMessage)

          });

        };

        send a message to the Chat
        const sendMessage = () => {

            get the message text from the text input
            let message = $('#message-to-send').val().trim();

           if the message isn't empty
            if (message.length) {

                emit the message event to everyone in the Chat
                myChat.emit('message', {
                    text: message
                });

                // clear out the text input
                $('#message-to-send').val('');

            }

            // stop form submit from bubbling
            return false;

        };

        // render messages in the list
        const renderMessage = (message, isHistory = false) => {

            // use the generic user template by default
            let template = userTemplate;

            // if I happened to send the message, use the special 
               template for myself
            if (message.sender.uuid == me.uuid) {
                template = meTemplate;
            }

            let el = template({
                messageOutput: message.data.text,
                time: getCurrentTime(),
                user: message.sender.state
            });

            // render the message
            if(isHistory) {
              $('.chat-history ul').prepend(el); 
            } else {
              $('.chat-history ul').append(el); 
            }

            // scroll to the bottom of the chat
            scrollToBottom();
        };
        // end of render message 

        const privaterenderMessage = (message, isHistory = false) => {

            // use the generic user template by default
            let template = userTemplate;

            // if I happened to send the message, use the special 
           template for myself
            if (message.sender.uuid == me.uuid) {
                template = meTemplate;
            }

            let el = template({
                messageOutput: message.data.text,
                time: getCurrentTime(),
                user: message.sender.state
            });

        init();
