microsoft-graph-api - 来自 GraphClient 的 PostDocument 引发异常 - 无法建立 SSL 连接

Question

我正在使用 MS GraphClient 使用 Microsoft 文档中的标准代码发布文档。我在 .NET Core 3.1 的 REST API 中的 Startup.ConfigureServices() 方法中设置 TLS1.2，如下所示。

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

我在发布文档调用之前获得了带有客户端令牌的授权。发布文档的代码片段是

int maxSlice = 320 * 1024;
using var stream = new MemoryStream(Convert.FromBase64String(document.FileContent));

var uploadSession = await graphclient.Drives[driveId].Items[driveItemId].ItemWithPath("File_Name").CreateUploadSession().Request().PostAsync();

var fileUploadTask = new LargeFileUploadTask<DriveItem>(uploadSession, stream, maxSlice);

UploadResult<DriveItem> uploadResult = await fileUploadTask.UploadAsync();

var fileUploaded = uploadResult.ItemResponse;

我能够获取 uploadSession，但是当它尝试执行 UploadAsync() 时，它会引发 SSL 连接失败。这种情况偶尔发生。如果发送了一系列 5 到 8 个文档，则其中一个或两个因 SSL 连接失败而失败。为每个要上传的文档获取一个具有授权的类的新实例。应用程序部署在 IIS 中，内存增加到一个非常好的数量。服务器可用内存超过 5GB。服务器和共享点之间的防火墙很好，没有看到任何网络呼叫中断的问题。但不知道 Microsoft Graphclient 是否有任何已知问题。

任何帮助表示赞赏。
