本篇文章给大家分享的是有关怎么在Vue中利用node实现音频录制播放功能,小编觉得挺实用的,因此分享给大家学习,希望大家阅读完这篇文章后可以有所收获,话不多说,跟着小编一起来看看吧。
vue部分:
安装recorderx
cnpm install recorderx --save
或者
npm install recorderx --save
在具体的组件中引入
<script>import axios from "axios";import {Toast} from "vant";import Recorderx, {ENCODE_TYPE} from "recorderx";const rc = new Recorderx();export default { data(){ return{ startime:null, endtime :null } }, methods:{ //录制语音recordingVoice() {// that.news_img = !that.news_imgrc.start().then(() => {this.startime = new Date();}).catch(error => {alert("获取麦克风失败");}); }, //发送语音async sendVoice() {rc.pause();this.endtime = new Date();let wav = rc.getRecord({encodeTo: ENCODE_TYPE.WAV,compressible: true});let voiceTime = Math.ceil((this.endtime - this.startime) / 1000);const formData = new FormData();formData.append("chatVoice", wav, Date.parse(new Date()) + ".wav");formData.append("voiceTime", voiceTime);let headers = {headers: {"Content-Type": "multipart/form-data"}};axios.post("/api/uploadChatVoice", formData, headers).then(res => {//console.log(res)if (res.data.status === 2) {rc.clear();let chatVoiceMsg = res.data.chatVoiceMsg;}}});},//播放语音playChatVoice(audio) {let audioUrl = audio;if(audioUrl){let audioExample = new Audio();audioExample.src = audioUrl; //想要播放的音频地址audioExample.play();}else{Toast('语音地址已被摧毁');}}, }};</script>
node部分:
这里我使用的是express框架搭建的后台
具体的获取前台的请求代码如下
安装multiparty
cnpm install multiparty --save
const express = require('express');const router = express.Router();const multiparty = require('multiparty');const NET_URL = 'http://127.0.0.1:3000/';router.post('/uploadChatVoice', (req, res, next) => { let form = new multiparty.Form(); form.uploadDir = 'chatVoiceUpload'; form.parse(req, (err, fields, files) => { console.log(files, fields) let chatVoiceUrl = NET_URL + files.chatVoice[0].path.replace(/\\/g, "/"); let chatVoiceTime = fields.voiceTime[0] console.log(chatVoiceUrl) if (chatVoiceUrl) { res.json({ status: 2, chatVoiceMsg: { chatVoiceTime, chatVoiceUrl, } }) } else { res.json({ status: 1, chatVoiceMsg: { chatVoiceTime: "", chatVoiceUrl: "" } }) } //console.log(files) })})
在app.js中,定义语音文件路径
app.use('/chatVoiceUpload', express.static('chatVoiceUpload'));
