.NET Graph SDK-OneDrive文件上传失败，并显示“不支持的段类型" [英] .NET Graph SDK - OneDrive File Upload Fails with "Unsupported segment type"

问题描述

尝试使用.NET SDK for Microsoft Graph上传文件.这是代码:

Trying to upload file using the .NET SDK for Microsoft Graph. Here is the code:

 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;

req.PutAsync方法引发异常，以上传包含文件内容的字节数组.我只是用一个小于100个字节的简单文本文件进行测试.异常包含错误的请求和不支持的细分类型.

An exception is thrown on the req.PutAsync method to upload the byte array containing the file contents. I am just testing with a simple text file, less than 100 bytes in size. The exception contains Bad Request and Unsupported segment type.

该文件是在OneDrive中创建的，但包含0个字节.

The file is created in OneDrive, but contains 0 bytes.

推荐答案

Me.ItemWithPath()需要/me后的完整路径.例如，_client.Me.ItemWithPath("/drives/driveId/items/itemId:/file/path").通过该方法，可以将通过API返回的ItemReference上返回的Path传递给ItemWithPath方法，而无需进行任何处理.

Me.ItemWithPath() requires the full path after /me. For example, _client.Me.ItemWithPath("/drives/driveId/items/itemId:/file/path"). This method is so the Path returned on the ItemReference returned via the API can be passed into the ItemWithPath method without any processing.

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();
