java - Apache HTTP 客户端 - 带有格式错误的质询的 401 错误：乱序 NTLM 响应消息警告

Question

我们在我们的应用程序中面临一个问题，当同时使用 HTTP 客户端发出两个 HTTP 请求时，有时即使通过了有效的 NTLM 身份验证，其中一个也会返回 401。

以下是我们日志的摘录

2019-09-07 16:12:27.620  INFO [nio-8087-exec-9] i.c.d.c.f.s.services.SharePointService   : Executing request: http://xxxxxx/sites/utp/_api/web/GetFolderByServerRelativeUrl('/sites/utp/Shared%20Documents/InstanceDocuments/41931/Input/uTW0DIz5dR') with headers: [Accept: application/json; odata=verbose, Content-Type: application/json; odata=verbose, X-RequestDigest: 0xA03754C393422E3EEFB176F804EAF942411EB26E7DF7270C8B4421203671D101077D103C54303961FEE57F5878A3248D53909B39CDD9EC6AB30D38A6FCBB8255,07 Sep 2019 10:28:34 -0000]

如上面的日志所示，第一个请求由线程 9 发送，第二个请求由线程 3 在 1 毫秒后发送。我们在线程 3 中收到警告，然后打印来自线程 9 的响应，然后返回错误 401。

警告说

格式错误的质询：乱序 NTLM 响应消息

请注意，404 是我们应用程序的有效响应。

目前，我们不确定这是 apache httpclient 库中的并发问题还是与服务器端配置有关。

Apache HTTP 客户端版本：4.5.5 目标服务器是 SharePoint 2013
