框架相关
Demo采用Mpvue框架，后端的WebSocket采用Node.js，文件服务器直接使用的微信小程序的云开发的存储。
储备知识
Node.js端WebScoket实现
// 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
})
})
小程序端实现
html
<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>
js
export default {
data() {
return {
// 存储聊天记录
chatContent: [],
// 录音控制器
recorderManager: null,
// 音频控制器
innerAudioContext: null
};
},
methods: {
// 按下按钮开始录音
startRecord() {
this.recorderManager.start({
format: "mp3"
});
},
// 松开按钮停止录音
stopRecord() {
this.recorderManager.stop();
},
// 播放录音
palyAudio(value) {
this.innerAudioContext.src = value;
this.innerAudioContext.play();
}
},
created() {
this.recorderManager = wx.getRecorderManager();
this.innerAudioContext = wx.createInnerAudioContext();
// 监听录音开始
this.recorderManager.onStart(res => {
console.log("recordStart");
});
// 监听录音结束
this.recorderManager.onStop(res => {
const audioName = new Date().getTime() + ".mp3";
// 上传录音文件
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
});
}
});
});
// 建立websocket链接
wx.connectSocket({
url: "ws://yoursiteandeport",
success: res => {
console.log("success", res);
},
fail: err => {
console.log("error", err);
}
});
// websocket消息监听
wx.onSocketMessage(data => {
console.log(data);
this.chatContent.push(data.data);
});
}
};
