asp.net 4.0 web forms routing - default/wildcard route(asp.net 4.0 网络表单路由 - 默认/通配符路由)
问题描述
当使用带有 Web 窗体的 ASP.NET 4.0 路由来生成将充当某种通配符的路由时,我有一种简单的方法吗?
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,在 WebForms 中,您必须为每个页面指定一个路由 - 我正在寻找某种通用路由,可以在不需要任何特定内容的情况下使用,也许直接从路径映射到路径,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 可能会映射到文件夹1/folder2/page.aspx
http://somedomain.com/folder1/folder2/page would possibly map to folder1/folder2/page.aspx
有什么建议吗?
谢谢
推荐答案
你可以像这样匹配所有剩余的路由:
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,并希望将其他任何内容发送到丢失"/404 页面.请务必将此作为 last 路由,因为它是一个通配符,可以捕获所有内容.
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.
您也可以用同样的方式注册一个路由,但在内部会映射到一个页面,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()));
该处理程序类将执行您的通配符映射,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;
}
}
这在奇怪的地方被打破了一点,以防止水平滚动,但你明白了整体观点.再次确保这是最后一个路线,否则它将处理您的所有路线.
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.
