c#asp.net路由地图中间件

我正在实现一些中间件，我只想在特定的路由上运行

/api

还有一些其他中间件应该始终运行，一些在特定于api的中间件之前运行，一些在特定于api的中间件之后运行。Startup.cs中的我的代码：

app.UseStaticFiles();
app.UseIdentity();
//some more middleware is added here

//my own middleware which should only run for routes at /api
app.UseCookieAuthMiddleware();

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

app.UseKendo(env);

加载中间件的顺序很重要，所以我想保持这个顺序。

app.UseCookieAuthMiddleware（）

只能在以/api开头的URL上运行，例如，

“/api、/api/test、/api？test”

。 我看到app.Map是一个选项，但是如何确保在app.Map之后添加所有其他中间件呢

编辑：地图跳过以下行时的示例：

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
   app.UseIdentity();
   //some more middleware is added here
   app.Map("/api", HandleApiRoutes);


   //lines below are skipped ONLY when map is used.
   //some more middleware should be added here 
   app.UseKendo(env);
}


private static void HandleApiRoutes(IApplicationBuilder app)
{
    app.UseCookieAuthMiddleware();
}

我的中间件：

public class CookieCheckMiddleWare
{
    private readonly RequestDelegate _next;

    public CookieCheckMiddleWare(RequestDelegate next)
    {
        _next = next;
    }

    public Task Invoke(HttpContext context)
    {

        Debug.WriteLine("Middleware is called" );

        //Call the next delegate/middleware in the pipeline this._next(context) is called no errors.
        return this._next(context);
    }
}

public static class CookieCheckMiddleWareMiddlewareExtensions
{
    public static IApplicationBuilder UseCookieAuthMiddleware(this IApplicationBuilder builder)
    {
        return builder.UseMiddleware<CookieCheckMiddleWare>();
    }
}

但是我想知道如何正确使用地图功能。

我删除了原来的答案并发布了一个新的答案

  public Task Invoke(HttpContext context)
  {
       var url = context.Request.Path.Value.ToString();
       var split = url.Split('/');
       if (split[1] == "api") //should do a extra check to allow /api?something
       {
          //middleware functions
       }
  }
