c# - 创建 DriveItem 时为 "Error getting value from ReadTimeout"

Question

我正在尝试使用 Microsoft Graph API 使用现有 DriveItem 的内容创建新的 SharePoint DriveItem。但是，在尝试创建 DriveItem 时出现以下错误。有人可以解释为什么吗？

编辑:简化为使用手动创建的 MemoryStream 对象

GraphServiceClient graphClient = GraphSDKHelper.GetAuthenticatedClient();
using (var docStream = new MemoryStream(1024))
{   
   var doc = new DriveItem
   {
        Content = docStream,
        Name = "00_newDoc.docx",
        ParentReference = new ItemReference
        {
            Id = "<folderId"
        }
    };
    var resultItem = await graphClient.Drives["<driveId>"].Items["<folderId>"].Request().CreateAsync(driveItem);
}

我可以使用以下命令直接上传文件内容，但我无法通过一次调用在 DriveItem 中指定更多元数据。

var resultItem = await graphClient.Drives["<driveId>"].Items["<folderId>"].ItemWithPath("00_newDoc.docx").content.Request().PutAsync<DriveItem(docStream);

错误:

内部异常:

我不知道你遇到了什么问题。

话虽如此，下载文件流只是为了将其作为新的 driveitem 再次上传是否有理由？

您是否考虑过使用复制功能？它应该像这样工作(我还没有尝试过):

// Copy item reference
ItemReference iRef = new ItemReference()
{
    DriveId = "b!ez3F6Nysf0yYklsI2gUdcx4e7pSsSDZClwfWe3rFh4mSiYpAIn5zRLcsEeS7g5dr",
    Id = "01YYVWN6F6Y2GOVW7725BZO354PWSELRRZ"
};

// Copy it
await graphClient.Me.Drives["<driveId>"].Items["<ItemId>"].Copy("copiedItem.txt", iRef).Request().PostAsync();

更新

API 不适合以这种方式使用。我不知道为什么它不能在一个电话中完成。我知道您必须首先使用 POST 创建项目(示例显示文件夹，但文件的想法是相同的)，然后是 PUT后续调用中的内容流。
