[网络协议]PubSub Websocket实时通信 - GoEasy在小程序中的使用

GoEasy在小程序中的使用

1.初始化GoEasy对象

 //在app.js的globalData初始化全局GoEasy对象
    globalData: {
        goEasy: GoEasy.getInstance({
            host:"hangzhou.goeasy.io",  //若是新加坡区域：singapore.goeasy.io
            appkey:"您的common key",
            modules:['pubsub']//根据需要，传入‘pubsub’或'im’，或数组方式同时传入
        })
    }

2.建立连接

2.1首先在index.js中引入

let goEasy = getApp().globalData.goEasy;
let pubSub = goEasy.pubsub;

2.2建立连接

    goEasy.connect({
        id:"001", //pubsub选填，im必填
        data:{"avatar":"/www/xxx.png","nickname":"Neo"}, //必须是一个对象，pubsub选填，im必填，用于上下线提醒和查询在线用户列表时，扩展更多的属性
        onSuccess: function () {  //连接成功
          console.log("GoEasy connect successfully.") //连接成功
        },
        onFailed: function (error) { //连接失败
          console.log("Failed to connect GoEasy, code:"+error.code+ ",error:"+error.content);
        },
        onProgress:function(attempts) { //连接或自动重连中
          console.log("GoEasy is connecting", attempts);
        }
    });

2.3订阅消息

    pubSub.subscribe({
    channel: "my_channel",//替换为您自己的channel
    onMessage: function (message) {
        console.log("Channel:" + message.channel + " content:" + message.content);
    },
    onSuccess: function () {
        console.log("Channel订阅成功。");
    },
    onFailed: function (error) {
        console.log("Channel订阅失败, 错误编码：" + error.code + " 错误信息：" + error.content)
    }
});

2.4发送消息

   pubSub.publish({
    channel: "my_channel",//替换为您自己的channel
    message: "Hello GoEasy!",//替换为您想要发送的消息内容
    onSuccess:function(){
        console.log("消息发布成功。");
    },
    onFailed: function (error) {
        console.log("消息发送失败，错误编码："+error.code+" 错误信息："+error.content);
    }
});

2.5取消订阅

     goEasy.pubSub.unsubscribe({
      channel: "my_channel",
      onSuccess: function () {
          alert("订阅取消成功。");
      },
      onFailed: function (error) {
          alert("取消订阅失败，错误编码：" + error.code + " 错误信息：" + error.content)
      }
  });

2.6断开连接

     //断开连接
    goEasy.disconnect({
        onSuccess: function(){
            console.log("GoEasy disconnect successfully.")
        },
        onFailed: function(error){
            console.log("Failed to disconnect GoEasy, code:"+error.code+ ",error:"+error.content);
        }
    });
