如何使用dotnet core 3.1为两个React应用程序设置路由？

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.SpaServices.ReactDevelopmentServer;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersWithViews();
        services.AddSpaStaticFiles(configuration =>
        {
            configuration.RootPath = "ClientApp/build";
        });
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // 其他中间件配置...

        app.UseStaticFiles();
        app.UseSpaStaticFiles();

        app.UseRouting();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller}/{action=Index}/{id?}");
        });

        app.UseSpa(spa =>
        {
            spa.Options.SourcePath = "ClientApp";

            if (env.IsDevelopment())
            {
                spa.UseReactDevelopmentServer(npmScript: "start");
            }
        });
    }
}

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersWithViews();
        services.AddSpaStaticFiles(configuration =>
        {
            configuration.RootPath = "build";
        });
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // 其他中间件配置...

        app.UseStaticFiles();

                name: "default",
                pattern: "{controller}/{action=Index}/{id?}");
        });

        app.UseSpa(spa =>
        {
            spa.Options.SourcePath = ".";

            if (env.IsDevelopment())
            {
                spa.UseReactDevelopmentServer(npmScript: "start");
            }
        });
    }
}

using Microsoft.AspNetCore.Mvc;

public class HomeController : Controller
{
    public IActionResult Index()
    {
        return View();
    }
}
