搭建网站的大致流程semester

下载组件

npm install recorder-core

封装方法

record.ts

//必须引入的核心
import Recorder from 'recorder-core';//引入mp3格式支持文件；如果需要多个格式支持，把这些格式的编码引擎js文件放到后面统统引入进来即可
import 'recorder-core/src/engine/mp3';
import 'recorder-core/src/engine/mp3-engine';
//录制wav格式的用这一句就行
import 'recorder-core/src/engine/wav';
import { RecordType } from './type';const record: RecordType = {RecordApp: null,recBlob: null,/**麦克风授权 */getPermission: (fn: Function | null) => {const newRec = Recorder({type: 'wav',bitRate: 16,sampleRate: 16000, //阿里采样率16000onProcess: function (buffers, powerLevel, duration, bufferSampleRate) {console.log(buffers);},});//打开录音，获得权限newRec.open(() => {record.RecordApp = newRec;fn({ status: 'success', data: '开启成功' });},(msg, isUserNotAllow) => {//用户拒绝了录音权限，或者浏览器不支持录音fn({ status: 'fail', data: msg });console.log((isUserNotAllow ? 'UserNotAllow，' : '') + '无法录音:' + msg);});},/**开始录音 */startRecorder: () => {if (record.RecordApp && Recorder.IsOpen()) {record.RecordApp.start();}},/** 停止录音 */stopRecorder: (fn: Function | null) => {try {if (!record) {console.error('未打开录音');return;}record.RecordApp.stop((blob, duration) => {console.log('录音成功', blob, '时长:' + duration + 'ms');if (blob) {record.recBlob = blob;const formData = new FormData();formData.append('audio', blob);fn({ loading: true });}/* eslint-enable */record.RecordApp.close();record.RecordApp = null;});} catch (err) {fn({ err: err });console.error('结束录音出错：' + err);record.RecordApp.close();record.RecordApp = null;}},/**关闭录音，释放麦克风资源 */destroyRecorder: () => {if (record.RecordApp) {record.RecordApp.close();record.RecordApp = null;}},/**暂停 */pauseRecorder: () => {if (record.RecordApp) {record.RecordApp.pause();}},/**恢复继续录音 */resumeRecorder: () => {if (record.RecordApp) {record.RecordApp.resume();}},
