.NET Graph SDK - OneDrive 文件上传失败 "Unsupported segment type"

Question

正在尝试使用 Microsoft Graph 的 .NET SDK 上传文件。这是代码：

 DriveItem file = new DriveItem()
        {
            File = new Microsoft.Graph.File(),
            Name = filename,
            ParentReference = new ItemReference()
            {
                DriveId = parent.ParentReference.DriveId,
                Path = path + "/" + filename
            }
        };

        var freq = _client
                .Me
                .Drive
                .Items[parent.Id]
                .Children
                .Request();

        // add the drive item
        file = await freq.AddAsync(file);

        DriveItem uploadedFile = null;
        using (MemoryStream stream = new MemoryStream(data))
        {
            var req = _client
                .Me
                .ItemWithPath(path + "/" + file.Name)
                .Content
                .Request();

            stream.Position = 0;
            // upload the content to the driveitem just created
            try
            {
                uploadedFile = await req.PutAsync<DriveItem>(stream);
            }
            catch(Exception ex)
            {
                Debug.WriteLine("File Put Error"); <<< FAILS HERE
            }
        }

        return uploadedFile;

上传包含文件内容的字节数组的req.PutAsync方法抛出异常。我只是用一个小于 100 字节的简单文本文件进行测试。异常包含 Bad Request 和 Unsupported segment type。

该文件是在 OneDrive 中创建的，但包含 0 个字节。

Answer 1

Me.ItemWithPath() 需要 /me 之后的完整路径。例如，_client.Me.ItemWithPath("/drives/driveId/items/itemId:/file/path")。通过此方法，可以将通过 API 返回的 ItemReference 上返回的 Path 传递到 ItemWithPath 方法中，而无需任何处理。

您要使用的是：

var req = _client
            .Me
            .Drive
            .ItemWithPath(path + "/" + file.Name)
            .Content
            .Request();

或：

var req = _client
            .Me
            .ItemWithPath(file.ParentReference.Path + "/" + file.Name)
            .Content
            .Request();

我发现有时在 SDK 语句中跳过设置包含文件夹 ID 的路径更容易...适用于 OneDrive 和统一组..

var createdFile = await graphClient.Me.Drive
                         .Items[currentDriveFolder.id]
                         .ItemWithPath(fileName)
                         .Content.Request()
                         .PutAsync<DriveItem>(stream);

我真的很希望能够像这样设置驱动器 ID 和文件夹 ID：

var createdFile = await graphClient
                        .Drives[driveId]
                        .Items[folderId]
                        .ItemWithPath(fileName)
                        .Content
                        .Request()
                        .PutAsync<DriveItem>(stream);
