我有一个 ASP.NET Core 站点在 Linux 上的 NGINX 反向代理后面运行。我遇到了一个问题，如果我通过附加了查询字符串的代理进行文件请求（即用于缓存清除），我会收到 404 错误，但如果我直接从应用程序请求完全相同的 URL（不是通过NGINX），它工作正常，如果我删除查询字符串，它也工作正常。

下面的示例（NGINX 代理正在侦听端口 5000，应用程序正在侦听端口 5002）...

如果我使用如下网址： http://host-name:5000/path/file.json

我得到了正确的结果，这就是应用程序控制台输出上显示的内容：

我收到 404 错误，这是应用程序控制台输出中显示的内容：

      Request finished in 379.4175ms 404 
Microsoft.AspNetCore.Hosting.Internal.WebHost:Information: Request finished in 379.4175ms 404

现在，我不清楚这是否是 NGINX 将其转发到 ASP.NET Core 应用程序的问题弄乱了，或者这不仅仅是 ASP.NET Core 应用程序（和/或 Kestrel）的问题被请求中显示的查询字符串和代理端口号的组合所抛弃。

NGINX 配置的相关部分如下所示：

server {
    server_name host-name;
    listen 5000 default_server;
    listen [::]:5000 default_server;
    location / {
        proxy_pass http://localhost:5002;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $http_host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Host $http_host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Path $request_uri;
    }
}

有任何想法吗？

编辑：

我已经将我的服务器块修改为如下所示：

server {
    server_name host-name;
    listen 5000 default_server;
    listen [::]:5000 default_server;
    root /var/www/path-to-debug/wwwroot;
    location / {
        if ($query_string ~ "^(.*)_dc=(.*)$") {
          rewrite ^(.*)$ $uri?;
        }
        try_files $uri @proxy;
    }
    location @proxy {
        proxy_pass http://localhost:5002;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $http_host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Host $http_host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Path $request_uri;
    }
}

现在正在正确获取特定文件（完全绕过 Kestrel），但这似乎与我的控制器调用之一混淆，该控制器调用也附加了 _dc=XXXX。

通过如下修改我的服务器代理块，我已经让这部分工作......这对我来说感觉就像一个黑客，但我还没有找到更好的解决方案。我还有其他问题，但如果/当我无法弄清楚时，我会为那些人发布单独的问题。

server {
    server_name host-name;
    listen 5000 default_server;
    listen [::]:5000 default_server;
    root /var/www/path-to-debug/wwwroot;
    location / {
        if ($query_string ~ "^(.*)_dc=(.*)$") {
          rewrite ^(.*)$ $uri?;
        }
        try_files $uri @proxy;
    }
    location @proxy {
        proxy_pass http://localhost:5002;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $http_host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Host $http_host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Path $uri;
    }
}
