Microsoft Graph API 客户端库 - 创建文件夹

Question

我正在尝试使用 Microsoft Graph (C# SDK) 在 SharePoint 中的现有文件夹下创建一个文件夹。我知道使用 Graph API 时在 SharePoint 或 OneDrive 上创建文件夹应该是相同的，但我仍然找不到任何好的在线参考。我找到的唯一一篇文章是一篇旧文章，其中只有一个 JavaScript 示例。

我有一个根文件夹A，我想B在A.

这是代码：

var driveRequestBuilder = graphClient
    .Sites[SharePointSiteId]
    .Lists[ListId]
    .Drive;

var folderRequestBuilder = driveRequestBuilder
    .Root
    .ItemWithPath("A");
var folderDriveItem = folderRequestBuilder
    .Request()
    .GetAsync()
    .Result; // This returns the root folder "A"'s info

var subFolderDriveItem = new DriveItem()
{
    Name = "B",
    Folder = folderDriveItem.Folder
};
var result = folderRequestBuilder
    .Request()
    .CreateAsync(subFolderDriveItem)
    .Result;

最后一行代码抛出一个异常AggregateException（因为 TPL），其中包含内部异常：

var driveRequestBuilder = graphClient
    .Sites[SharePointSiteId]
    .Lists[ListId]
    .Drive;

var folderRequestBuilder = driveRequestBuilder
    .Root
    .ItemWithPath("A");
var folderDriveItem = folderRequestBuilder
    .Request()
    .GetAsync()
    .Result; // This returns the root folder "A"'s info

var subFolderDriveItem = new DriveItem()
{
    Name = "B",
    Folder = folderDriveItem.Folder
};
var result = folderRequestBuilder
    .Request()
    .CreateAsync(subFolderDriveItem)
    .Result;

我想知道创建子文件夹的正确语法。

Answer 1

如果是子文件夹，则创建文件夹的端点应该是

POST https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/drive/root:/{path}:/children
Content-Type: application/json

{
  "name": "New folder name",
  "folder": { },
  "@microsoft.graph.conflictBehavior": "rename"
}

示例msgraph-sdk-dotnet：

var folder = new DriveItem
{
    Name = "<sub folder name>",
    Folder = new Folder()
};

var result = await graphClient
    .Sites[siteId]
    .Lists[listId]
    .Drive
    .Root
    .ItemWithPath("<folder path>")
    .Children
    .Request()
    .AddAsync(folder);
