Question

尝试使用.NET SDK for Microsoft Graph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;

在req.PutAsync方法上抛出异常以上载包含文件内容的字节数组。我只是测试一个简单的文本文件，大小不到100个字节。该异常包含错误请求和不支持的段类型。

该文件在OneDrive中创建，但包含0个字节。

Me.ItemWithPath（）需要/ me之后的完整路径。例如，_client.Me.ItemWithPath（“/ drives / driveId / items / itemId：/ file / path”）。这个方法是通过API返回的ItemReference上返回的Path可以传递给ItemWithPath方法而无需任何处理。

您想要使用的是：

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

或：

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

我发现有时更容易跳过在SDK语句中设置包含文件夹ID的路径...在OneDrive和统一组中工作..

import * as datasvc from "services/datasvc"

我真的希望能够像这样设置驱动器ID和文件夹ID：

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

.NET Graph SDK - OneDrive文件上载失败，出现“不支持的段类型”
