app如何申请位置权限？

import { abilityAccessCtrl, common } from '@kit.AbilityKit';
import { BusinessError } from '@kit.BasicServicesKit';
let atManager = abilityAccessCtrl.createAtManager();
let context = getContext(this) as common.UIAbilityContext;
// 向用户请求位置权限设置。
atManager.requestPermissionsFromUser(context, ["ohos.permission.APPROXIMATELY_LOCATION"]).then((data) => {
  console.info('data:' + JSON.stringify(data));
  console.info('data permissions:' + data.permissions);
  console.info('data authResults:' + data.authResults);
}).catch((error: BusinessError) => {
  console.error(`Failed to request permissions from user. Code is ${error.code}, message is ${error.message}`);
})
