小程序中开启录音功能（使用wepy）

1.检查是否获取到录音权限---获取录音权限

onLoad(options, data) {
    this.judgeRecord().then(res=>{
        if(res==true) {
            this.recordInit = true;
            this.$apply();
        }
    })
    this.$apply();
}

　　

judgeRecord() {
            return new Promise(function (resolve, reject) {
                wx.getSetting({
                    success(res) {
                        if (!res.authSetting['scope.record']) {
                            if (res.authSetting['scope.record'] == undefined) {
                                wx.authorize({
                                    scope: 'scope.record',
                                    success() {
                                        // 用户已经同意小程序使用录音功能，后续调用    wx.startRecord 接口不会弹窗询问
                                        // wx.startRecord()
                                        resolve(true)
                                    },
                                    fail() {
                                        resolve(false)
                                    }
                                })
                            }else{
                                wx.showModal({
                                    title: '请求授权录音权限',
                                    content: '需要获取您的录音权限，请确认授权',
                                    success: function (res) {
                                        if (res.cancel) {
                                            wx.showToast({
                                                title: '拒绝授权',
                                                icon: 'none',
                                                duration: 1000
                                            })
                                            resolve(false)
                                        } else if (res.confirm) {
                                            wx.openSetting({
                                                success: function (dataAu) {
                                                    if (dataAu.authSetting["scope.record"] == true) {
                                                        wx.showToast({
                                                            title: '授权成功',
                                                            icon: 'success',
                                                            duration: 1000
                                                        })
                                                        resolve(true)
                                                        //再次授权，调用wx.getLocation的API
                                                    } else {
                                                        wx.showToast({
                                                            title: '授权失败',
                                                            icon: 'none',
                                                            duration: 1000
                                                        })
                                                        resolve(false)
                                                    }
                                                }
                                            })
                                        }
                                    }
                                })
                            }

                        }else{
                            resolve(true)
                        }
                    }
                });
            })

        }            

2.初始加载如果用户拒绝授权，则在需要操作录音的位置继续调用授权

onTouchStart(e) {
                this.$apply();
                if (!this.recordInit) {
                    this.judgeRecord();
                    return false;
                }
            },
