Question

我有一个使用nginx的Web服务器，配置了HTTPS和基本身份验证。

我尝试使用带有PowerShell的WebClient查询它

$wc = new-object System.Net.WebClient
$wc.Credentials = Get-Credential
return $wc.DownloadString($url)

这适用于以下$url s

https://server.com
https://server.com/
https://server.com/directory/
https://server.com/page.php
https://server.com/directory/index.php

但对于以下$url，我得到The remote server returned an error: (401) Unauthorized.

https://server.com/directory
https://server.com/otherdirectory
https://server.com/directory/directory

我起初认为这是由于重定向，但鉴于一些工作示例，这不会有意义。也许这是我的nginx配置？

我目前认为这是WebClient课程中的一个错误。以下是我与服务器交互的摘要：

------------------------------------------------------------------------
GET /directory HTTP/1.1
Host: example.com

此时，WebClient会抛出异常，说明服务器返回问题中陈述的错误。

它应该为auth令牌提供第三个请求，或者至少使用提供的auth令牌响应另一个请求。

我希望其他人（最好使用.NET 4.5.2）确认这一点，所以我可以接受这个作为答案。

请求没有斜杠的目录时，WebClient获取401
