c# - InvalidRequest 在驱动器之间移动 DriveItem

问题描述

我正在尝试将DriveItem位于父 SharePoint 网站的根驱动器中的一个移动到子子网站。

父站点： mydomain.sharepoint.com/sites/Graph- 列表：文档

子站点 mydomain.sharepoint.com/sites/Graph/SubwebA- 列表：文档

我正在使用 Microsoft Graph SDK v3.25.0：

var client = GetGraphClient();
var destDriveItem = new DriveItem
{
  ParentReference = new ItemReference
  {
    DriveId = destDriveID,
    Id = destDriveFolderID
  }
};

var response = await client
  .Drives[driveID]
  .Items[sourceDriveItemID]
  .Request()
  .UpdateAsync(destDriveItem);

所有 ID 均有效，但UpdateAsync返回此错误：

ServiceException: Code: invalidRequest
Message: Requested move requires an async response, add 'Prefer: respond-async' to allow

如果我在同一站点中移动DriveItem两个（文档库）之间的代码，则相同的代码可以工作。Drives

该问题可能与此GitHub 问题有关（尽管这是为了在同一站点中移动）

解决方案

这是不受支持的操作。从文档中：

无法使用此请求在驱动器之间移动项目。

相反，您需要拨打两个电话：

  1. 将文件复制到新位置
  2. 从旧位置删除文件
var client = GetGraphClient();

var parentReference = new ItemReference
{
  DriveId = destDriveID,
  Id = destDriveFolderID
};

var copyResponse = await client
  .Drives[driveID]
  .Items[sourceDriveItemID]
  .Copy(name, parentReference)
  .Request()
  .PostAsync();

var deleteResponse = await client
  .Drives[driveID]
  .Items[sourceDriveItemID]
  .Request()
  .DeleteAsync();
