initWebSocket(){
    var api=this.uploadimage.split('//')[1].split('/')[0]

    console.log(wsuri)     //     ws://xxx.xxx.x.xxx:8888/websocket/6
    this.websock = new WebSocket(wsuri);
    this.websock.onopen = this.websocketonopen;
    this.websock.onmessage = this.websocketonmessage;
    this.websock.onerror = this.websocketonerror;
    this.websock.oncolose = this.websocketclose;
    
},
websocketonopen(){

},
websocketonmessage(e){
