5.申請授權（可組合申請）接上文

let p: Permissions[] = ['ohos.permission.ACTIVITY_MOTION', 'ohos.permission.CAMERA','ohos.permission.LOCATION', 'ohos.permission.APPROXIMATELY_LOCATION'];
PermissionUtil.requestPermissions(p).then((grant) = > {
     if (grant) {
       ToastUtil.showToast(`申請授權，已通過...`);
     }
})

如果第一次申請用戶沒有同意，可二次申請

PermissionUtil.requestPermissionOnSettingEasy(p).then((result) = > {
   ToastUtil.showToast(`申請授權，結果：${result}`);
});

6.申請授權，拒絕后可二次申請

let p: Permissions[] = ['ohos.permission.ACTIVITY_MOTION', 'ohos.permission.CAMERA', 'ohos.permission.LOCATION', 'ohos.permission.APPROXIMATELY_LOCATION'];
PermissionUtil.requestPermissionsEasy(p).then((result) = > {
    ToastUtil.showToast(`申請授權，結果：${result}`);
})
