nodejs  +  websocket + protobufjs 


## 前端 连接发送：

``` javascript

this.$socket.initWebsocket('ws://192.168.3.21:9009/ws', this.wsMessage, this.wsError)

  sendMessage () {
        // 跟后端协商，需要什么参数数据给后台
      const message = protoHelper.Message.create()
      message.dataType = protoHelper.Message.DataType.ControlType
      message.control = {
        'forward': 10000, // 向前
        'backward': 2, // 向后
        'left': 3, // 向左
        'right': 4// 向右
      }
      // message.payload = 'data_type'
      console.log(message)
      let dataBuffer = protoHelper.Message.encode(message).finish()
      // debugger
      // 发起ws请求
      this.$socket.sendWebsocket(dataBuffer)
    },

  // ws连接成功，后台返回的ws数据，组件要拿数据渲染页面等操作
    wsMessage (data) {
      // const dataJson = data
      console.log('data:', data)
      // debugger
      let decodeData = protoHelper.Message.decode(new Uint8Array(data))
      console.log('decodeData:', decodeData)
      let obj = protoHelper.Message.toObject(decodeData, {
        // dataType: Number,
        // control: Object
        json: true
      })
      console.log('obj--:', obj)
    },
