asp.net 4.0 Web窗体路由 - 默认/通配符路线 [英] asp.net 4.0 web forms routing - default/wildcard route

问题描述

我有使用ASP.NET 4.0路由的Web窗体产生将充当某种通配符的路由时，一个简单的方法？

I there a simple way when using ASP.NET 4.0 routing with Web Forms to produce a route that will act as some kind of wildcard?

在我看来，这WebForms的范围内，你必须指定每一页的路线 - 我要寻找某种通用路由那些需要没有什么特别，也许是从路径直接映射到路径，以便可以使用..

It seems to me that within WebForms, you have to specify a route for every page - I am looking for some kind of generic route that can be used where nothing specific is required, perhaps mapping directly from path to path so...

http://somedomain.com/folder1/folder2/page 将可​​能映射到文件夹1 /文件夹2 /页。 ASPX

http://somedomain.com/folder1/folder2/page would possibly map to folder1/folder2/page.aspx

有什么建议？

感谢

推荐答案

您可以匹配这样所有剩余的路线：

You can match all remaining routes like this:

routes.MapPageRoute("defaultRoute", "{*value}", "~/Missing.aspx");

在这种情况下，我们知道所有路由，并想送什么别的了失踪/ 404页。只要确保把这个作为过去的路线，因为它是一个通配符，将捕获的一切。

In this case, we know all routes, and want to send anything else to a "missing"/404 page. Just be sure to put this as the last route, since it is a wildcard and will catch everything.

另外，您可以注册一个路线以同样的方式，但是在内部做映射到一个页面，如下所示：

Alternatively you could register a route the same way, but internally does mapping to a page, like this:

routes.Add(new Route("{*value}", new DefaultRouteHandler()));

这是处理类会做你的通配符映射，是这样的：

That handler class would do your wildcard mapping, something like this:

public class DefaultRouteHandler : IRouteHandler
{
  public IHttpHandler GetHttpHandler(RequestContext requestContext)
  { 
    //Url mapping however you want here:
    var pageUrl = requestContext.RouteData.Route.Url + ".aspx";

    var page = BuildManager.CreateInstanceFromVirtualPath(pageUrl, typeof(Page)) 
               as IHttpHandler;
    if (page != null)
    {
      //Set the <form>'s postback url to the route
      var webForm = page as Page;
      if (webForm != null) 
         webForm.Load += delegate { webForm.Form.Action = 
                                    requestContext.HttpContext.Request.RawUrl; };
    }
    return page;
  }
}

这是打破奇数地方prevent水平滚动了一下，但你得到的全局观念。再次，确保这是在最后的路线，否则它会处理的所有的你的路由。

This is broken a bit in odd places to prevent horizontal scrolling, but you get the overall point. Again, make sure this is the last route, otherwise it'll handle all your routes.
