Vue Cli 3项目使用融云IM实现聊天功能的方法

介绍：前台使用vue开发的单页面，后台使用ant design pro单页面，实现手机端和后台聊天功能。

效果如图(PC+移动)：

一、申请融云账号（token、appKey）

建议先看教程：sdk使用介绍

过一遍教程，接下来开始写

二、引入融云IM

如图：

位置：public/index.html,引入

<script src="https://cdn.ronghub.com/RongIMLib-2.3.5.min.js"></script>

三、可以正常使用RongIMLib其自带方法了

app.vue 不是全代码（因为只是连接）

created () { //生命周期函数-可发起求
 let that = this
 //融云初始化
 RongIMLib.RongIMClient.init('4z3hrv4ovrt'); //------------------------------重要填写appkey
 that.beforeIm() //设置监听，必须先设置监听，再连接
 that.nowIm() //连接融云
 },
 methods: {
 ...mapMutations({ //读取最新消息列表，并设置----------------------------重要
  getAnswer:'getAnswer'
 }),
 beforeIm(){
  let that = this
  // 连接状态监听器
  RongIMClient.setConnectionStatusListener({
   onChanged: function (status) {
    // status 标识当前连接状态
    switch (status) {
     case RongIMLib.ConnectionStatus.CONNECTED:
      console.log('链接成功');
      break;
     case RongIMLib.ConnectionStatus.CONNECTING:
      console.log('正在链接');
      break;
     case RongIMLib.ConnectionStatus.DISCONNECTED:
      console.log('断开连接');
      break;
     case RongIMLib.ConnectionStatus.KICKED_OFFLINE_BY_OTHER_CLIENT:
      console.log('其他设备登录');
      break;
     case RongIMLib.ConnectionStatus.DOMAIN_INCORRECT:
      console.log('域名不正确');
      break;
     case RongIMLib.ConnectionStatus.NETWORK_UNAVAILABLE:
      console.log('网络不可用');
      break;
    }
   }
  });

  // 消息监听器
  RongIMClient.setOnReceiveMessageListener({
   // 接收到的消息
   onReceived: function (message) {
    // 判断消息类型
    switch(message.messageType){
     case RongIMClient.MessageType.TextMessage:
      // message.content.content => 文字内容
      //----------------------------重要-------把获取的消息存放在store中，全局公用homeIm.vue要使用
      console.log('8080',message,message.content.content)
      that.getAnswer(message.content)
      break;
     case RongIMClient.MessageType.VoiceMessage:
      // message.content.content => 格式为 AMR 的音频 base64
      break;

      // message.content.content => 位置图片 base64
      break;

      // message.content.url => 原图 URL
      break;

      break;
     default:

    }
   }
  });
 },
 nowIm(){
 //自己的token------从接口获取，写到缓存
  var token = JSON.parse(localStorage.getItem('userInfo')).IMUser.token//"WzrthC5f4UfuiI7dIwCQ5fwtGfqCdobpowIZkcQnj8PQOQuAJb/nIi1ayzGFwJguvbQZxbJH3x0=";

完了，okk，文中所需icon，请自行到阿里icon下载

结尾：项目中需要配置rem。
