採用HTML5的WebSocket協議,首先定義一個url地址:前端

websockUrl:'ws://192.168.1.119:11000/aa/roomChat',//webSocket聊天地址

初始化方法vue

initWebSocket(){//網頁聊天
    let that=this;
    //判斷當前瀏覽器是否支持WebSocket
    if ('WebSocket' in window) {
        try {
            that.chat.websockObj = new WebSocket(that.chat.websockUrl);
        } catch(e) {
            console.log(e);
        }
    }else {
        that.$Message.warning('您當前瀏覽器不支持在線聊天!');
        return false;
    }

    //鏈接成功創建的回調方法
    that.chat.websockObj.onopen = function () {
        that.chat.chatList.push({tip:true,message:'正在鏈接中...',sendId:''})
        that.chat.websockObj.send('testMsg201811121726');
    };

    //鏈接發生錯誤的回調方法
    that.chat.websockObj.onerror = function () {
        that.chat.chatList.push({tip:true,message:'WebSocket鏈接發生錯誤',sendId:''});
    };

    //接收到消息的回調方法
    that.chat.websockObj.onmessage = function (event) {
        that.receiveMsg(event.data);
        // that.heartCheck();
    }

    //鏈接發生錯誤重連
    that.chat.websockObj.onclose = function () {
        // that.reconnect();
    };
},

發送消息node

sendMsg(){//發送消息
    let that=this;
    if(that.chat.text.length == 0){
        that.$Message.destroy();
        that.$Message.warning('您尚未輸入內容!');
        return false;
    }
    if((new Date().getTime() - that.chat.sendTimeInterval)/1000 < 2){
        that.$Message.destroy();
        that.$Message.warning('信息發送太頻繁了,請休息一會再發!');
        return false;
    }
    that.chat.sendTimeInterval=new Date().getTime();
    that.loading2=true;
    if(that.chat.websockObj.readyState == 1){
        that.chat.websockObj.send(that.chat.text);
        that.chat.text='';
        setTimeout(function(){
            that.loading2=false;
        },50);
    }else{
        that.$Message.warning('鏈接還未創建!');
    }
}

接受消息,接受消息時能夠作一些判斷,好比是否鏈接成功,地方是否已經下線等,這些判斷標識能夠本身發也能夠由後臺發送,webpack

receiveMsg(str){//接受消息
  let obj=document.querySelector('#chat-body');
  let h=obj.clientHeight;
  let conObj=JSON.parse(str);

  // 檢測鏈接是否成功
  if(conObj.message.indexOf('testMsg201811121726') != -1){
        if(conObj.message.indexOf('18ece5e7e003423da379aba5da84cdbc') == -1){
            let t=new Date();
            let time=initDate(t.getHours())+':'+initDate(t.getMinutes());
            this.chat.chatList.push({tip:true,message:time+'<br>鏈接已經創建,能夠開始聊天了',sendId:''});
            this.chat.chatList.splice(0,1);
        }
        return false;
  }

  // 檢測對方是否下線
  if(conObj.message.indexOf('offLineMsg201811121808') != -1){
        this.chat.chatList.push({tip:true,message:'對方已下線',sendId:''});
        return false;
  }


  // 檢測是否發送失敗
  if(conObj.message.indexOf('18ece5e7e003423da379aba5da84cdbc') != -1){
        conObj.message=conObj.message.replace('18ece5e7e003423da379aba5da84cdbc', '');
        conObj.isSuccess=false;
  }

  // 保持最新內容在視野內
  setTimeout(function(){
        if(obj.scrollHeight > h){
            obj.scrollTop = obj.scrollHeight;
        }  
  }, 50);
},

關閉鏈接ios

destroyed: function() {
  //頁面銷燬時關閉長鏈接
  this.chat.websockObj.close();
}

以上並非完整的聊天邏輯代碼,只記錄順序流程,還須要後端小夥伴的配合。nginx

騰訊視音頻

視音頻功能採用的是騰訊的實時音視頻功能,使用流程爲:
註冊帳號——購買實時音視頻服務——下載sdk——生成測試帳號——先後端聯調。
須要注意的是測試時必須是https協議或者localhos下,個人這個項目須要三路視頻,所以建立了三個房間,三個帳號;下面是詳細代碼:web

htmlsegmentfault

<video id="maxVideo" autoplay playsinline></video><!-- A正面 -->
<video id="localVideo" width="100%" muted autoplay playsinline></video><!-- B正面 -->
<video id="remoteVideo2" width="100%" autoplay playsinline></video><!-- A側面 -->
<video id="remoteVideo3" width="100%" autoplay playsinline></video><!-- 抓屏 -->

初始化:

initRTC(){
    var that=this;
    that.user1.objectRTC = new WebRTCAPI({
        "userId": that.user1.userId,
        "userSig": that.user1.userSig,
        "sdkAppId":that.sdkappid
    });
    that.user1.objectRTC.getLocalStream({
        video:true,
        audio:true,
    },function( info ){
        var stream = info.stream;
        that.user1.objectRTC.enterRoom({
            roomid : that.user1.roomId,
            privateMapKey:that.user1.privateMapKey
        },function(){
            // 枚舉音頻設備
            that.user1.objectRTC.getAudioDevices( function(devices){
                if(devices.length > 0){
                    that.user1.objectRTC.chooseAudioDevice( devices[0] );
                }else{
                    that.$Message.warning('沒有檢測到音設備!');
                }
            });
            // 枚舉視頻設備
            that.user1.objectRTC.getVideoDevices( function(devices){
                if(devices.length > 0){
                    that.user1.objectRTC.chooseVideoDevice( devices[0] );
                }else{
                    that.$Message.warning('沒有檢測到視頻設備!');
                }
                
            });

            //進房成功,音視頻推流
            that.user1.objectRTC.startRTC({
                role : "user",   //畫面設定的配置集名 (見控制檯 - 畫面設定 )
                stream: stream
            });
        },function(){

        });
    },function ( error ){
        console.error( error )
    });

    // 本地
    that.user1.objectRTC.on("onLocalStreamAdd", function(data){
        if( data && data.stream){
            document.querySelector("#localVideo").srcObject = data.stream;
        }
    });

    //遠端流 新增/更新
    that.user1.objectRTC.on("onRemoteStreamUpdate", function(data){
        if( data && data.stream){
            document.querySelector("#maxVideo").srcObject = data.stream;
        }
    });

參考了這篇文章:如何寫一個好看的實用的日曆

與後端配合過程當中遇到的問題

一、騰訊視音頻服務先後臺聯調複雜
緣由:視音頻須要localhsot或者https協議才能訪問
(1)採用nginx代理,使用https在線聯調,發現前端沒獲取靜態資源,使用腳手架啓動的服務靜態資源都在緩存中,沒有放在dist中,打包後纔有,無法測試;
(2)本地測試,使用webpack-dev-server代理設置爲localhost,可是後臺接口就不通了,須要調用後臺接口動態獲取房間帳戶和密鑰,不過能夠先寫死測試,勉強能夠;
(3)測試接口的話只能本地測試完打包發給開發,讓開發部署到本身服務下進行測試,效率低,麻煩

若是webpack可以像eclipse自帶的服務那樣,點擊保存就把改動發佈到tomcat下就行了,隨時編譯

二、接口調試問題
後臺只能盲寫接口,無法測試,我本身寫了個簡陋的接口測試頁面給開發用

<template>
<div>
    <Form ref="suggessForm" >
        <FormItem>
            <Input type="text" v-model="psyUrl.url" placeholder="/qd/user/getUserPic"></Input>
        </FormItem>
        <FormItem >
            <Input v-model="psyUrl.content" type="textarea" :rows="4" class='mb10' :maxlength='100' placeholder="name=aa&age=10&sex=男"></Input>
        </FormItem>
        <FormItem >
            <Button type="primary" :loading="loading" @click="interface">
                <span v-if="!loading">測試</span>
                <span v-else>Loading...</span>
            </Button>
        </FormItem>
    </Form>
</div>
</template>

<script>
export default {
    mounted(){

    },
    data() {
        return {
            loading:false,
            psyUrl:{
              url:'/qd/user/getUserPic',
              content:'name=aa&age=10&sex=男' 
            }
        };
    },
    methods: {
      interface(){
          let that=this;
          let params={};
          let arr = that.psyUrl.content.split('&');
          that.loading=true;
          $.each(arr, function(index, val) {
             params[val.split('=')[0]]=val.split('=')[1];
          });
          console.log(params)
          $.post(psyBase.path+that.psyUrl.url,params, function(data, textStatus, xhr) {
              that.loading=false;
              console.log(data)
          },'text');
      }
    }
};
</script>

應該有在線mock數據的吧?

打包過程當中遇到的問題

靜態資源比較多,有圖片、字體文件、js文件、css文件,我想把靜態資源放在單獨一個目錄文件夾內,打包後指望是這樣:

resource文件夾內文件

參考網上的設置不論怎麼改都不行,每次都要手動修改main.css文件的路徑
dist/resource改爲./resource

下面是配置:

entry: {
    main: './src/main',
    vendors: './src/vendors'
},
devServer: {
    host:'192.168.1.230',
    // host:'localhost',
    disableHostCheck: true,
    proxy:[
        {
            context: ['/qd', '/logout','/sys','/roomChat'],
            target: 'http://192.168.1.119:11000/psycholConsult/',
            secure: false,
            changeOrigin:true
        }
    ]
},
output: {
    path: path.join(__dirname, './dist'),
    publicPath:'./resource/',
},
module: {
    rules: [{
            test: /\.vue$/,
            loader: 'vue-loader',
            options: {
                loaders: {
                    css: ExtractTextPlugin.extract({
                        use: ['css-loader', 'autoprefixer-loader'],
                        fallback: 'vue-style-loader'
                    })
                }
            }
        },
        {
            test: /iview\/.*?js$/,
            loader: 'babel-loader'
        },
        {
            test: /\.js$/,
            loader: 'babel-loader',
            exclude: /node_modules/
        },
        {
            test: /\.(less|css)$/,
            use: ExtractTextPlugin.extract({
                use: ['css-loader?minimize', 'autoprefixer-loader','less-loader'],
                fallback: 'style-loader'
            })
        },
        // 小於10K的圖片將直接以base64的形式內聯在代碼中,能夠減小一次http請求。
        // 大於10k的呢?則直接file-loader打包,
        {
            test: /\.(gif|jpg|png|woff|svg|eot|ttf)\??.*$/,
            loader: 'url-loader',
            options:{
                limit: 10240,//圖片大小
                name: 'resource/[name].[hash].[ext]'//圖片名稱規則
            }
        },
        {
            test: /\.(html|tpl)$/,
            loader: 'html-loader'
        }
    ]
},

webpack-dev-server代理

編輯webpack.base.config.js文件

devServer: {
    host:'192.168.1.230',
    // host:'localhost',
    disableHostCheck: true,
    proxy:[
        {
            context: ['/qd', '/logout','/sys','/roomChat'],
            target: 'http://192.168.1.119:11000/psy/',
            secure: false,
            changeOrigin:true
        }
    ]
},
