c# - 调用图形 api 失败并出现莫名其妙的日志，并且未捕获套接字异常

问题描述

描述错误 我们在调用 graph.microsoft.com 时遇到间歇性故障。异常不是很清楚，调试问题非常困难。我实际上无法在本地复制它。

我们的应用是在 Kubernetes 上运行的 .net core 2.1 应用。我们尝试使用以下代码获取用户成员资格

var memberIds = await graphClient.Me.TransitiveMemberOf.Request(userOptions).GetAsync();
userMemberships = memberIds.Select(o => o.Id).ToList();

while (memberIds.NextPageRequest != null)
{
     memberIds = await memberIds.NextPageRequest.GetAsync();
     userMemberships.AddRange(memberIds.Select(o => o.Id).ToList());
}

从跟踪中并不清楚错误实际上在哪里，但上面的行是我们称之为 graph 的唯一行，所以我们尝试将其包装在 try catch 中：

try {
 // get members
} catch(ServiceException e) {
  // log something
}

这是异常跟踪：

异常消息

The SSL connection could not be established, see inner exception. Unable to read data from the transport connection: Connection reset by peer. Connection reset by peer

重现 我无法重现。我设法通过在我的本地计算机上阻止 graph.microsoft.com 来强制执行类似的异常。这给了我以下信息： 单击此处查看屏幕截图 这个错误实际上是在 try catch 中捕获的，所以我很困惑为什么另一个没有。

预期的行为 我期望一个 ServiceException 更好地解释问题以及如何解决它

软件包版本 Microsoft.Graph：v1.17.0 Microsoft.Graph.Core：v1.18.0

我已经阅读了一些其他上下文，这可能是由于套接字饥饿。有什么办法可以避免每次都创建一个新的 Graph 服务实例。我找不到太多可以告诉我这是否可能的材料。我知道您可以使用 httpclient 实例来做到这一点并继续重用它。我可以看到有一个 GraphClientFactory 但没有关于如何使用它或是否可以重用它的信息。

如果您能提供见解，那就太好了。谢谢
