• 1、插件使用

1）推送插件：cordova.plugins.notification.local

插件安装：cordova plugin add cordova-plugin-local-notification

或者：cordova plugin add https://github.com/katzer/cordova-plugin-local-notifications.git

git地址：https://github.com/katzer/cordova-plugin-local-notifications

2）ng2-STOMP-Over-WebSocket插件 用于和后台通信

插件安装：npm i --save stompjs   npm i --save sockjs-client   npm i --save ng2-stomp-service

git地址：https://github.com/devsullo/ng2-STOMP-Over-WebSocket

• 2、代码实现

1）推送代码实现

 clickObj = {};
  /**
   * @函数名称：sentInfo
   * @param
   * @作用：消息推送
   * @return：obj
   * @date 2018/7/19
   */
  sentInfo(item) {
    this.initLocalNotifications();
    const me = this;
    //新版本使用 add 可以替换 schedule
    const localNotifications = this.localNotifications;
    if (localNotifications.add) {
      localNotifications.add({
        id: item.charNum,
        title: item.text,
        text: item.label,
        at: item.at,
        badge: 2,
        sound: 'res://platform_default',//默认值
        icon: 'res://ic_popup_reminder', //默认值
        autoClear: true,//默认值
        ongoing: true,  //默认值
        data: item
      });
    } else {
      localNotifications.schedule({
        id: item.charNum,
        title: item.text,
        text: item.label,
        at: item.at,
        badge: 2,
        autoClear: true,//默认值
        ongoing: true,  //默认值
        data: item
      });
    }
    me.clickObj[item.charNum] = false;
    // 跳转到详情页面
    localNotifications.on('click', function(notification){
      // TODO 待优化 处理多次注入问题
      if (me.clickObj[notification.id]) {
        return;
      }
      if (!me.clickObj[notification.id]) {
        me.navCrt.push(EventInfoModal, notification.data);
      }
      me.clickObj[notification.id] = true;
    }, item.charNum);
  }

2）和后台对接代码实现

/**
   * @函数名称：stompFn
   * @param
   * @作用：websocket相关业务处理
   * @date 2018/7/19
   */
  stompFn() {
    //configuration
    const hostUrl = this.http.getUrl('/api/websocket');
    this.stomp.configure({
      host: hostUrl,
      debug: true,
      queue: {'init':false}
    });

    //start connection
    this.stomp.startConnect().then(() => {
      this.stomp.done('init');
      console.log("链接成功");
      //subscribe
      this.subscription = this.stomp.subscribe('/topic/subscribe', this.response);

      //send data
      // this.stomp.send('destionation',{"data":"data"});

      //unsubscribe
      // this.subscription.unsubscribe();

      //disconnect
      // this.stomp.disconnect().then(() => {
      //   console.log( 'Connection closed' )
      // })

    });
  }
  infoId = 0; // 消息id
  //response
  public response = (data) => {
    this.infoId++;
    const item = {
      img: 'data:image/jpeg;base64,' + data.checkJpg,
      text : this.getTitle(data),//single.checkName,
      label: this.getLabel(data),
      time: Number(data.time_norm),
      videoUrl: data.combiner_output_path+'/'+data.combiner_output_file+'/'+data.time+'.jpg.mp4',
      charNum: this.infoId
    };
    this.sentInfo(item);
  };

• 3、真机测试

1）部署内网websocket连接不上

原因：host没有添加内网地址，正确连接地址例如 http://192.1.1.1:8888//api/websocket

切记订阅地址不需要添加http地址

this.stomp.configure({
               host: hostUrl,
               debug: true,
               queue: {'init':false}
           });

2）部署外网websocket连接不上

nginx配置问题

解决办法参考：http://www.cnblogs.com/duanweishi/p/9286461.html
