微信小程序，录音管理 - recorderManager 封装

录音管理封装

封装了录音管理的权限校验，没有权限则拉起授权

注册调用

    const recodManage = Record()
    recodManage.create({
        recordConfig: {
          duration: 60000,
          format: 'mp3',
        },// 非必传：参数参照微信 recorderManager API
        onStart: () => {
            console.log('录音开始了')
        },
        onStop: fileInfo => {
            console.log('录音结束了，文件信息：', fileInfo)
        }
    })
    
    // 使用举例：
    recodManage.action() // 开始录音
    
    recodManage.stopRecord() // 停止录音

代码如下

/**
   * 录音封装
   */
  Record() {
    class recordManage {
      constructor() {
        this.recordContext = null
        this.recordStatus = false // 录音当前状态

        }
      }

        this.recordOnStop = config.onStop
        if (typeof config.recordConfig === 'object') {

        console.log('录音初始化完成');
      }
