uni-app的websocket在app中无法关闭，h5中可以关闭，有人知道怎么解决吗？

直接这样关闭 uni.closeSocket()

在renderjs中写html原生的webSocket倒是可以用，也是没有办法的办法了。有人知道正常写法的话麻烦告诉一下。
template：

<view id="weighWs" :prop="weighWsMessage" :change:prop="weighWs.updateWeighWs"></view>

vue的script：

data(){  
  return {  
    weighWsMessage: {}    
  }  
},  
methods:{  
  changeWeight(val) {  
      this.centerWeight = val  
  },  
  connectWs(){  
      // 加个时间戳使得每次都能触发updateWeighWs  
      this.weighWsMessage = {type: 'connectWs', value: 'ws://xxxxxxxx', timeStamp: new Date()}  
  },  
  closeWs(){  
     this.weighWsMessage = {type: 'closeWs', timeStamp: new Date()}  
  }  
}

renderjs：

<script module="weighWs" lang="renderjs">  
// #ifndef H5  
let ws  
export default {  
  mounted() {  
    this.connectWs('ws://192.168.xxxx')  
  },  
  destroyed() {  
    this.closeWs()  
  },  
  methods: {  
    updateWeighWs(newVal) {  
      if (newVal.type === 'closeWs') {  
        this.closeWs()  
      } else if (newVal.type === 'connectWs') {  
        this.connectWs(newVal.value)  
      }  
    },  
    closeWs() {  
      ws.close()  
      ws = null  
    },  
    connectWs(url) {  
      ws && this.closeWs()  
      const _this = this  
      ws = new WebSocket(url);  

      ws.onopen = function (evt) {  
        console.log("Connection open ...");  
      };  

      ws.onmessage = function (evt) {  
        console.log("Received Message: " + evt.data);  
        _this.$ownerInstance.callMethod('changeWeight', JSON.parse(evt.data).value)  
      };  

      ws.onclose = function (evt) {  
        console.log("Connection closed.");  
      };  
    }  
  }  
}  
// #endif  
</script>

close里的参数有一个code，1000表示正确。默认是1000.随便用一个其它值，看下行不行，我感觉好像可以：

uni.closeSocket({  
code: 500  
})
