ASP.NET Core routing prefix

Question

I'm developing an ASP.NET Core application. My application hosted with NGinx on url http://somedomain.com/MyApplication.

I need all requests routed to prefix /MyApplication.

My problem with controllers actions responses redirects to somedomain.com, not to somedomain.com/MyApplication.

Is there any way to configure routes to use prefix /MyApplication?

UPD: for example

        [HttpGet]
        [AllowAnonymous]
        public async Task<IActionResult> Login(string returnUrl = null)
        {
            // Clear the existing external cookie to ensure a clean login process
            await HttpContext.SignOutAsync(IdentityConstants.ExternalScheme);

            ViewData["ReturnUrl"] = returnUrl;
            return View();
        }

redirects to somedomain.com, but i need to somedomain.com/MyApplication

Answer 1

you can use the PathBase middleware just before Mvc like this :

partial class Startup {

    public void Configure(
        IApplicationBuilder app,
        IHostingEnvironment env
    ) {
        app.UsePathBase(new PathString("/MyApplication"));
        app.UseMvc();
    }

}

with the PathBase middleware, no need to change any mvc code, it will automatically add to the request and response.

please refer to https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.builder.usepathbaseextensions.usepathbase?view=aspnetcore-2.2

If you are using MVC, you can try to change the default route format. In Startup.cs replace the line

app.UseMvc(routes => { routes.MapRoute(name: "default", template: "/{controller=Home}/{action=Index}/{id?}"); });

with this one:

app.UseMvc(routes => { routes.MapRoute(name: "default", template: "MyApplication/{controller=Home}/{action=Index}/{id?}"); });

Let me know if it's what you need

[Route("MyApplication")]
public class MyController : Controller
{
    [HttpGet]
    public async Task<IActionResult> Login(string returnUrl = null)
    {
        // Blah!
    }
}
