Vue+node实现音频录制播放功能

实现效果：

主要实现代码逻辑部分，具体页面结构就不一一介绍了。

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_img
				rc.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'));
