小程序实现简单语音聊天的示例代码

// 基于WS插件
 
// 引入ws插件
var WebSocketServer = require("ws").Server;
// 实例化WebSocket
var wss = new WebSocketServer({ port: 9090 });
// 初始化客户端数组
var clients = [];
 
// 建立链接监听
wss.on('connection', function (ws) {
 clients.push(ws);
 ws.on("message", function (message) {
  clients.forEach(function (ws1) {
   if (ws1 !== ws) {
    ws1.send(message)
   }
  })
 })
})
 
// 建立链接关闭监听
ws.on("close", function (message) {
 clients = clients.filter(function (ws1) {
  return ws1 !== ws
 })
})

<div>
 <button @click="palyAudio(value)" v-for="(value,index) in chatContent" :key="index">)))))</button>
 <button class="botom-button" @touchstart="startRecord" @touchend="stopRecord">输入语音</button>
</div>

export default {

   });

  },
  // 播放录音

   wx.cloud.uploadFile({
    cloudPath: audioName,
    filePath: res.tempFilePath,
    success: upload => {
     this.chatContent.push(upload.fileID);
     // 通过websocket传递录音连接
     wx.sendSocketMessage({
      data: upload.fileID
     });
    }
