RecorderManager 全局惟一的錄音管理器
RecorderManager
對象DOM
結構<image @click="recordAction" :src="recordImg" class="record"/>
import iconRecord from '../../static/images/icon_record.png' import iconRecording from '../../static/images/icon_recording.png' // ... data() { recordImg: iconRecord, // 錄音按鈕的圖標 rm: null, // 錄音管理器 }, // ... mounted() { if (this.rm === null) { // 錄音管理器若是沒有初始化就先初始化 this.rm = uni.getRecorderManager() } // 綁定回調方法 this.rm.onStart((e) => this.onStart(e)) this.rm.onPause((e) => this.onPause(e)) this.rm.onResume((e) => this.onResume(e)) this.rm.onInterruptionBegin((e) => this.onInterruptionBegin(e)) this.rm.onInterruptionEnd((e) => this.onInterruptionEnd(e)) this.rm.onError((e) => this.onError(e)) }, // ... methods: { // ... recordAction() { if (this.recordImg === iconRecord) { // 設置格式爲MP3,最長60S,採樣率22050 this.rm.start({ duration: 600000, format: 'mp3', sampleRate: 22050, }) // 開始錄音後綁定中止錄音的回調方法 this.rm.onStop((e) => this.onStop(e)) } else if (this.recordImg === iconRecording) { this.rm.stop() }, }, onStart(e) { console.log('開始錄音', this.question, this.subQuesIndex) this.recordImg = iconRecording console.log(e) }, onPause(e) { console.log(e) afterAudioRecord() }, onResume(e) { console.log(e) }, onStop(e) { console.log(e) this.recordImg = iconRecord // 結束錄音以後上傳錄音 this.uploadMp3Action(e) }, onInterruptionBegin(e) { console.log(e) }, onInterruptionEnd(e) { console.log(e) }, onError(e) { console.log(e) }, uploadMp3Action(e) { // TODO uploadMp3 }, },
globalData
中增長兩個屬性audioPlaying
,audioRecording
// src/App.vue export default { globalData: { // 保證全局只有一個音頻處於播放狀態且錄音與播放操做互斥 audioPlaying: false, audioRecording: false, }, // ... },
Util
中增長判斷方法// src/lib/Util.js // 結束錄音以後釋放錄音能力 export function afterAudioRecord() { getApp().globalData.audioRecording = false } // 結束音頻播放以後釋放音頻播放能力 export function afterAudioPlay() { getApp().globalData.audioPlaying = false } /** * 判斷是否能夠錄音或者播放 * @param {string} type play | record */ export function beforeAudioRecordOrPlay(type) { const audioPlaying = getApp().globalData.audioPlaying const audioRecording = getApp().globalData.audioRecording if (audioPlaying ||audioRecording) { uni.showToast({ title: audioPlaying ? '請先暫停其餘音頻播放' : '請先結束其餘錄音', icon: 'none' }) return false } else { if (type === 'play') { getApp().globalData.audioPlaying = true } else if (type === 'record') { getApp().globalData.audioRecording = true } else { throw new Error('type Error', type) } return true } }
recordAction
方法import { beforeAudioRecordOrPlay, afterAudioRecord} from '../../lib/Utils'; // ... recordAction() { - if (this.recordImg === iconRecord) { + if (this.recordImg === iconRecord && beforeAudioRecordOrPlay('record')) { // 設置格式爲MP3,最長60S,採樣率22050 this.rm.start({ duration: 600000, format: 'mp3', sampleRate: 22050, }) // 開始錄音後綁定中止錄音的回調方法 this.rm.onStop((e) => this.onStop(e)) } else if (this.recordImg === iconRecording) { this.rm.stop() + afterAudioRecord() }, },
這樣就避免了屢次錄音
補全咱們的uploadMp3Action
方法,咱們使用uni-app
的uni.uploadFile()
方法來上傳錄音文件html
uploadMp3Action(e) { const filePath = e.tempFilePath const option = { url: 'xxx', filePath, header, formData: { filePath }, name: 'audio', } uni.showLoading({ title: '錄音上傳中...' }) return await uni.uploadFile(option) uni.hideloading() }
RecorderManager
對象beforeDestroy() { this.rm = null }
