asp.net-mvc - 两个 Kestrel 进程可以监听同一域中的不同 URL 吗？

Question

假设我有两个名为“a”和“b”的应用程序。如何让它们同时在同一域的不同虚拟目录下运行？

Identity 应该监听 http://localhost:8080/a/

var host = new WebHostBuilder()
    .UseKestrel()
    .UseContentRoot(Directory.GetCurrentDirectory())
    .UseIISIntegration()
    .UseUrls($"http://*:8080/a/")
    .UseStartup<Startup>()
    .Build();
host.Run();

用户配置文件应监听 http://localhost:8080/userprofiles/

var host = new WebHostBuilder()
    .UseKestrel()
    .UseContentRoot(Directory.GetCurrentDirectory())
    .UseIISIntegration()
    .UseUrls($"http://*:8080/b/")
    .UseStartup<Startup>()
    .Build();
host.Run();

这些应用程序单独运行，但是当我同时启动它们时，我收到此错误

crit: Microsoft.AspNetCore.Server.Kestrel[0]
Unable to start Kestrel.
System.IO.IOException: Failed to bind to address http:/ /*:8080/userprofiles: address already in use. ---> System.AggregateException: One or more errors occurred.

Kestrel 本身无法共享端口。您可以在 IIS 后面运行它并执行此操作，也可以使用 WebListener。
