如何使用第三方库中的@pura/harmony-utils(V1.3.3）申请授权工具类二

5.申请授权（可组合申请）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(`申请授权，已通过...`);
     }
})

如果第一次申请用户没有同意，可二次申请

PermissionUtil.requestPermissionOnSettingEasy(p).then((result) = > {
   ToastUtil.showToast(`申请授权，结果：${result}`);
});

6.申请授权，拒绝后可二次申请

let p: Permissions[] = ['ohos.permission.ACTIVITY_MOTION', 'ohos.permission.CAMERA', 'ohos.permission.LOCATION', 'ohos.permission.APPROXIMATELY_LOCATION'];
PermissionUtil.requestPermissionsEasy(p).then((result) = > {
    ToastUtil.showToast(`申请授权，结果：${result}`);
})

7.完整UI代码

import { abilityAccessCtrl, Permissions } from '@kit.AbilityKit';
import { LogUtil, PermissionUtil, ToastUtil, WantUtil } from '@pura/harmony-utils';
import { BusinessError } from '@kit.BasicServicesKit';

      }

}

注：部分权限需要在真机上使用，部分权限需要在模拟器设置进行模拟使用
