ASP .Core MVC 配置应用程序根 url

Question

I have two ASP .Core MVC applications that are hosted under the same url.我有两个 ASP .Core MVC 应用程序，它们托管在同一个 url 下。
I've managed to separate them with Nginx so that a certain path goes to app-2 , while the rest goes to app-1 :我设法用 Nginx 将它们分开，以便某个路径转到app-2 ，而其余路径转到app-1 ：
http://host -> app-1 http://host -> app-1
http://host/setup -> app-2 http://host/setup -> app-2

My problem comes when the user connects to app-2 , as the application still thinks it's app-root is http://host .当用户连接到app-2 ，我的问题就出现了，因为应用程序仍然认为它的 app-root 是http://host 。
This leads to the client encountering a 404 when for example style sheets are downloaded, since app-2.css exists under http://host/setup/css but the application searches in http://host/css .这会导致客户端在下载样式表时遇到 404，因为app-2.css存在于http://host/setup/css但应用程序在http://host/css 。

The "include"-lines in the .cshtml file in app-2 look like this: app-2 .cshtml文件中的“include”行如下所示：

<link rel="stylesheet" type="text/css" href="@Url.Content("~/css/app-2.css")" asp-append-version="true" />

Is there some way of "overriding" or telling app-2 that ~ should refer to <host>/setup/css/ instead of <host>/css/ ?有什么方法可以“覆盖”或告诉app-2 ~应该引用<host>/setup/css/而不是<host>/css/ ？
I really don't want to hardcode it in case the url changes at some point.我真的不想对其进行硬编码，以防 url 在某些时候发生变化。

After many hours of searching I found no way of altering the application root for the entire webserver.经过数小时的搜索，我发现无法更改整个网络服务器的应用程序根目录。
What I ended up doing instead was create class PathHelper with options and added it to Startup.cs :我最终做的是使用选项创建类PathHelper并将其添加到Startup.cs ：

class PathHelper
{
    public PathHelper(IOptions<PathHelperOptions> opt)
    {
        Path = opt.Path;
        
        if (Path.StartsWith('/'))
        {
            Path = Path[1..];
        }
        if (!Path.EndsWith('/'))
        {
            Path = Path + '/';
        }
    }

    public string Path { get; }
}

class PathHelperOptions
{
    public string Path { get; set; }
}

# Startup.cs
public void ConfigureServices(IServiceCollection services)
{
  services
      .AddScoped<PathHelper>()
      .Configure<PathHelperOptions>(opt =>
      {
          opt.Path = this.configuration.GetSection("URL_SUFFIX");
      });

  [...]
}

I then used it in the .cshtml files like this:然后我在.cshtml文件中使用它，如下所示：

@inject PathHelper helper
<link rel="stylesheet" type="text/css" href="@Url.Content(helper.Path + "css/app-2.css")" asp-append-version="true" />

Answer 2

I think the easiest way is to include the base tag in pages coming from 'app-2'.我认为最简单的方法是在来自“app-2”的页面中包含base标签。

Try it like this:像这样尝试：

<html>
    <head>
        <base href="http://host/setup">
    </head>

Now your relative links are sent to 'app-2'.现在您的相关链接被发送到“app-2”。
