"classfiy" : "asp.net core"
"author" : "飞扬"
"viewTimes" : 254

&gt;实现的功能：
	删除BlogController的Url地址中的Blog

```C#
 //Startup.cs =&gt; Configure
 app.UseEndpoints(endpoints =&gt;
    {
        endpoints.MapControllerRoute(
        name: "default_bolg",
        defaults: new { controller = "Blog" },
        pattern: "{action=Details}/{id?}");
    });

app.UseEndpoints(endpoints =&gt;
    {
        endpoints.MapGet("/Blog/", context =&gt;
        {
            var id = context.Request.RouteValues["Id"]?.ToString();
            var action = context.Request.RouteValues["Action"]?.ToString();
            context.Response.Redirect($"/{action}/{id}");
            return Task.CompletedTask;
        });
    });
```
```c#
//RoterEx.cs
using Microsoft.AspNetCore.Routing;
public class RoterEx : IRouter
    {
        public VirtualPathData GetVirtualPath(VirtualPathContext context)
        {
            return null;
        }

public async Task RouteAsync(RouteContext context)
        {
            if (context.RouteData.Values.Equals("Blog"))
            {
                context.RouteData.Values.Remove("Blog");
            }
        }
    }
```
