1. 创建音频对象上下文

// 创建音频上下文
    let innerAudioContext = uni.createInnerAudioContext({
      useWebAudioImplement: false,
    })
    this.innerAudioContext = innerAudioContext
    // 创建录音全局唯一对象
    let recorderManager = uni.getRecorderManager()
    this.recorderManager = recorderManager
    // 监听录音结束
    recorderManager.onStop((e) => {
      let duration = (e.duration / 1000).toFixed(1)
      this.voice = {
        src: e.tempFilePath,
        duration: duration,
      }
      this.$emit('success', this.voice)
    })

2. 点击开始录音方法

 /**
     * 开始录音
     */
    start() {
      let recorderManager = this.recorderManager
      uni.vibrateShort({
        success: (e) => {
          if (!this.isClick) {
            this.interval = setInterval(() => {
              this.duration = this.duration + 0.1
            }, 100)
            recorderManager.start()
            this.isActive = true
          }
        },
      })
    }

3. 点击结束录音方法

/**
    * 结束录音
    */
   end() {
     let recorderManager = this.recorderManager
     recorderManager.stop()
     this.isActive = false
     if (this.interval) {
       clearInterval(this.interval)
       this.interval = null
       this.duration = 0
     }
     setTimeout(() => {
       this.isClick = false
     }, 200)
   },

4. 播放录音方法

    play() {
      if (this.voice) {
        this.innerAudioContext.src = this.voice.src
        this.innerAudioContext.play()
      }
    },
