HarmonyOS 是否有api可以判断用户是否授予某项权限

import bundleManager from '@ohos.bundle.bundleManager'; 
import abilityAccessCtrl,{Permissions} from '@ohos.abilityAccessCtrl'; 
export class RequestModel { 
  * 同步检查校验应用是否被授予权限 
  */ 
  async checkAccessTokenSync(bundleName:Permissions):Promise<boolean>{ 
    let atManager = abilityAccessCtrl.createAtManager(); 
    let tokenId = await this.getTokenId() 
    let data = atManager.verifyAccessTokenSync(tokenId,bundleName) 
    if(data === abilityAccessCtrl.GrantStatus.PERMISSION_GRANTED) { 
      return true 
    } else  { 
      return false 
    } 
  } 
 
  /** 
   * 获取应用的身份标识 
   * 系统应用可以通过bundleManager.getApplicationInfo获取,普通应用可以通过bundleManager.getBundleInfoForSelf获取 
   */ 
  async getTokenId() { 
    let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION; 
    let data = await bundleManager.getBundleInfoForSelf(bundleFlags) 
    return data.appInfo.accessTokenId 
  } 
}
