問題描述

當(dāng)使用帶有 Web 窗體的 ASP.NET 4.0 路由來生成將充當(dāng)某種通配符的路由時，我有一種簡單的方法嗎?

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?

在我看來，在 WebForms 中，您必須為每個頁面指定一個路由 - 我正在尋找某種通用路由，可以在不需要任何特定內(nèi)容的情況下使用，也許直接從路徑映射到路徑，所以...

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 可能會映射到文件夾1/folder2/page.aspx

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

有什么建議嗎?

謝謝

推薦答案

你可以像這樣匹配所有剩余的路由:

You can match all remaining routes like this:

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

在這種情況下，我們知道所有路由，并希望將其他任何內(nèi)容發(fā)送到丟失"/404 頁面.請務(wù)必將此作為 last 路由，因為它是一個通配符，可以捕獲所有內(nèi)容.

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.

您也可以用同樣的方式注冊一個路由，但在內(nèi)部會映射到一個頁面，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()));

該處理程序類將執(zhí)行您的通配符映射，如下所示:

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;
  }
}

這在奇怪的地方被打破了一點，以防止水平滾動，但你明白了整體觀點.再次確保這是最后一個路線，否則它將處理您的所有路線.

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.
