websocket加vue发送图片

要在Vue中使用WebSocket发送图片，您可以按照以下步骤进行操作：

1. 在Vue中安装WebSocket库，例如 `npm install --save vue-native-websocket`

2. 在Vue组件中导入WebSocket库，并在 `created()` 钩子函数中初始化WebSocket连接：

import VueNativeSock from 'vue-native-websocket'

export default {
  created() {
    this.$options.sockets = {
      connect: () => {
        console.log('WebSocket connected')
      },
      disconnect: () => {
        console.log('WebSocket disconnected')
      }
    }

    this.$connect('ws://localhost:8080')
  }
}

3. 创建一个input元素以允许用户选择要上传的图片：

<input type="file" ref="fileInput" @change="uploadImage">

4. 在 `uploadImage` 方法中，将选择的图片转换为Base64编码，并将其发送到WebSocket服务器：

methods: {
  uploadImage() {
    const file = this.$refs.fileInput.files[0]
    const reader = new FileReader()

    reader.onload = (event) => {
      const base64Image = event.target.result

      this.$socket.sendObj({
        type: 'image',
        data: base64Image
      })
    }

    reader.readAsDataURL(file)
  }
}

5. 在WebSocket服务器上，您可以接收到消息并将其转换回图像：

const WebSocketServer = require('websocket').server
const http = require('http')

const server = http.createServer((request, response) => {
  console.log('Received request for', request.url)
  response.writeHead(404)
  response.end()
})

server.listen(8080, () => {
  console.log('Server is listening on port 8080')
})

const wsServer = new WebSocketServer({
  httpServer: server
})

wsServer.on('request', (request) => {
  const connection = request.accept()
  console.log('WebSocket connection accepted')

  connection.on('message', (message) => {
    if (message.type === 'utf8') {
      console.log(`Received message ${message.utf8Data}`)
    } else if (message.type === 'binary') {
      console.log('Received binary message')

      const image = Buffer.from(message.binaryData, 'base64')
      // 处理图像
    }
  })

  connection.on('close', (reasonCode, description) => {
    console.log('WebSocket disconnected')
  })
})

这样，您就可以使用WebSocket在Vue中发送图片。
