服务器 returns 代码：使用 CreateUploadSession 上传文件时出现 InternalServerError

Question

我的应用程序可以正常通过连续上传将文件上传到 OneDrive、SharePoint。 目前，它已损坏，并在调用

时抛出 InternalServerError

var uploadSession = await graphClient.Drive.Items["01KGPRHTV6Y2GOVW7725BZO354PWSELRRZ"].ItemWithPath("_hamilton.png").CreateUploadSession().Request().PostAsync();

我执行以下操作： [https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/dev/tests/Microsoft.Graph.DotnetCore.Test/Requests/Functional/OneDriveTests.cs][1]

异常：

Status Code: InternalServerError
Microsoft.Graph.ServiceException: Code: InternalServerError

我们也遇到了同样的问题，但似乎是图 API 的问题，今天（2020 年 3 月 10 日）（可能）发生了变化。有人在 https://github.com/microsoftgraph/msgraph-sdk-dotnet/issues/646 提交了一个 github 问题，您可以关注，但如果您真的必须完成这项工作，您可以通过使用反射覆盖请求 url 来破解它。

var regex = new Regex(@"/microsoft\.graph\.createUploadSession$");
var reqUrl = uploadSessionReq.RequestUrl;
typeof(DriveItemCreateUploadSessionRequest)
    .GetProperty(nameof(DriveItemCreateUploadSessionRequest.RequestUrl))
    .GetSetMethod(nonPublic: true)
    .Invoke(
        uploadSessionReq,
        new[]
        {
            regex.Replace(reqUrl, "/createUploadSession")
        }
    );
