    1. 使用npm或者yarn安装 goeasy

    命令如下:(1).yarn init -y(初始化),(2). yarn add goeasy(安装)

     

    2. main.js导入

    (1).import GoEasy from 'goeasy';

    (2).

     1 // 在main.js里初始化全局的GoEasy对象
     2 Vue.prototype.$goEasy = new GoEasy({
     3     host: "hangzhou.goeasy.io", //应用所在的区域地址: 【hangzhou.goeasy.io | singapore.goeasy.io】
     4     appkey: "my_appkey", //替换为您的应用appkey
     5     onConnected: function() {
     6         console.log('连接成功!')
     7     },
     8     onDisconnected: function() {
     9         console.log('连接断开!')
    10     },
    11     onConnectFailed: function(error) {
    12         console.log('连接失败或错误!')
    13     }
    14 });

     

    3 . 在具体页面进行推送接收 (挺简单的,估计你看看就会了)

    注意的一点就是,分发和接收消息都是通过唯一的频道来传输和获取

      1 <template>
      2     <view class="content">
      3         <view v-for="(item, index) in historyList" :key="index">{{ item.content.avatar }} {{ item.content.name }} {{ item.content.time }}</view>
      4         <image class="logo" src="/static/logo.png" @click="handleSendMsg"></image>
      5         <view class="text-area">
      6             <text class="title">{{ msgInfo }}</text>
      7         </view>
      8         <input type="text" value="" @input="handleMsg" />
      9     </view>
     10 </template>
     11 
     12 <script>
     13 export default {
     14     data() {
     15         return {
     16             title: 'Hello',
     17             msgInfo: {},
     18             options: {},
     19             historyList: []
     20         };
     21     },
     22     onLoad(options) {
     23         this.options = options;
     24     },
     25     onReady() {
     26         // 接收(只要初始化一次即可使用)
     27         this.$goEasy.subscribe({
     28             channel: '这里填唯一的频道,仅限字符串', //替换为您自己的channel
     29             onMessage: message => {
     30                 this.msgInfo = JSON.parse(message.content);
     31                 console.log('message', message, this.msgInfo);
     32                 // console.log('Channel:' + message.channel + ' content:' + message.content);
     33             }
     34         });
     35     },
     36     methods: {
     37         handleSendMsg() {
     38             // 高级功能(历史记录按付费获取消息记录,9.9元最近30条)
     39             this.$goEasy.history(
     40                 {
     41                     channel: '这里填唯一的频道,仅限字符串', //必需项
     42                     limit: 10 //可选项,返回的消息条数,默认为100条,最多1000条
     43                 },
     44                 response => {
     45                     if (response.code == 200) {
     46                         for (let i = 0, len = response.content.messages.length; i < len; i++) {
     47                             response.content.messages[i].content = JSON.parse(response.content.messages[i].content);
     48                         }
     49                         this.historyList = response.content.messages;
     50                     }
     51                 }
     52             );
     53         },
