HarmonyOS 申请定位权限失败问题

精确定位不可以单独申请，要先申请模糊定位权限后再去申请精确定位权限，而且对于精确单位申请的时候，必须和模糊定位权限一起申请

// 定位能力所需要的权限

private permissions: Array<Permissions> = ['ohos.permission.LOCATION', 'ohos.permission.APPROXIMATELY_LOCATION'];

class PermissionsUtil {

  /**
   * 校验应用是否被授予定位权限
   * @param permissions
   * @returns

    let applyResult: boolean = false;
    for (let permission of permissions) {
      let grantStatus: abilityAccessCtrl.GrantStatus = await this.checkAccessToken(permission);
      if (grantStatus === abilityAccessCtrl.GrantStatus.PERMISSION_GRANTED) {
        applyResult = true;
      } else {
        applyResult = false;
      }
    }
    if (!applyResult) {
      this.requestPermissions(permissions);
    }
  }
