三，配置完成后会自动生成AppID等信息，把这些信息发给后端

在App.vue里面

onLaunch: function() {
            initTabBar();
            //#ifdef APP-PLUS  
            //开启推送
            uni.subscribePush({
                provider: "unipush",
                success: function(res) {
                    console.log("success:" + JSON.stringify(res));
                }
            });
            let osname = plus.os.name
            console.log(osname)
            if (osname == 'Android') {
                uni.onPush({
                    provider: "unipush",
                    success: function() {
                        console.log("监听透传成功");
                    },
                    callback: function(data) {
                        console.log("接收到透传数据：" + JSON.stringify(data));
                        plus.push.createMessage(data.data, {});
                    }
                });
            }
            // 监听在线消息事件
            if (osname == 'iOS') {
                plus.push.addEventListener('receive', function(msg) {
                    plus.push.createMessage(msg.content, "LocalMSG", {
                        cover: false
                    });
                    setTimeout(() => {
                        plus.push.clear();
                    }, 3000)
                }, false);
            }
            plus.push.addEventListener(
                "click",
              //这里写业务逻辑
                function(data) {
                    console.log(data);
                },
                false
            );
            plus.push.addEventListener('receive',function(res){
                    let options = {cover:false};
                    console.log(res)
                    console.log(res.content)
                    plus.push.createMessage(res.content,res.payload,options);
            },false)
        }
