小程序中开启录音功能（使用wepy） - fairy62

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();
}

　　

 1 judgeRecord() {
 2             return new Promise(function (resolve, reject) {
 3                 wx.getSetting({
 4                     success(res) {
 5                         if (!res.authSetting[\'scope.record\']) {
 6                             if (res.authSetting[\'scope.record\'] == undefined) {
 7                                 wx.authorize({
 8                                     scope: \'scope.record\',
 9                                     success() {
10                                         // 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
11                                         // wx.startRecord()
12                                         resolve(true)
13                                     },
14                                     fail() {
15                                         resolve(false)
16                                     }

18                             }else{

22                                     success: function (res) {
23                                         if (res.cancel) {
24                                             wx.showToast({
25                                                 title: \'拒绝授权\',

30                                         } else if (res.confirm) {

34                                                         wx.showToast({
35                                                             title: \'授权成功\',
36                                                             icon: \'success\',

38                                                         })
39                                                         resolve(true)
40                                                         //再次授权，调用wx.getLocation的API
41                                                     } else {
42                                                         wx.showToast({
43                                                             title: \'授权失败\',

46                                                         })
47                                                         resolve(false)
48                                                     }
49                                                 }
50                                             })
51                                         }

53                                 })
54                             }
55 
56                         }else{
57                             resolve(true)
58                         }
59                     }
60                 });
61             })
62 
63         }            

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;
                }
            },
