捕获无效的网址 [英] Trapping for invalid URLs
问题描述
我继承了一个ASP.NET网络应用程序，我希望将其重组为更多
逻辑文件夹层次结构（超过150个）应用程序根目录中的WebForms，但很多
用户通过他们已经添加到他们的
收藏夹中的完全限定的URL访问该网站。 />
有没有办法在页面请求被处理之前捕获它以便我可以将
重定向到新文件夹结构中的位置？例如。用户试图获得
访问权限：
http://www.mysite.com/viewmonthlystats.aspx
但该页面现在位于
http://www.mysite.com/stats/monthly/view.aspx
我希望我可以在
Global.asax中使用Application_BeginRequest做一些事情，但是在我调用它之前我得到了404错误。 />

Hi,
I''ve inherited an ASP.NET web app which I want to restructure into a more
logical folder hierarchy (over 150 WebForms in the app''s root), but lots of
users access the site by fully-qualified URLs which they''ve added to their
Favourites.
Is there any way to trap a page request before it''s processed so that I can
redirect to its location in the new folder structure? E.g. user tries to
access:
http://www.mysite.com/viewmonthlystats.aspx
but that page now resides in
http://www.mysite.com/stats/monthly/view.aspx
I''d hoped that I could do something with Application_BeginRequest in
Global.asax, but I get the 404 error before that is even invoked.

推荐答案
Mark，
最简单的方法做你想要的是实现自定义HTTP
处理程序。在您这样做之前，我建议您在下面的文章中看看
。

它讨论并提供URL重写的解决方案。

Mark,
The easiest way to do what you want is to implement a custom HTTP
Handler. Before you do that though, I recommend that you have a look
at the following article.
http://msdn.microsoft.com/library/de...lrewriting.asp
It discusses, and provides a solution for, URL rewriting.

感谢您的回复 - 我先查看了这篇文章但是由于最后的警告，在这种情况下，没有想到它会给我带来帮助。
当然，使用ASP.NET级别重写，如果请求是成功从IIS传递到ASP.NET引擎的
，则只能进行URL重写
。当用户
请求具有.aspx扩展名的页面时，会自然发生这种情况。但是，如果你想让这个人能够输入一个可能实际上并不存在的
网址，而是想改写现有的
ASP.NET页面，你需要创建模拟目录和Default.aspx页面，或者配置
IIS以便所有传入
请求被盲目地路由到ASP.NET引擎。
我不能在这个实例中重新配置IIS，因为它的公共站点是
托管有一个商业ISP，可以理解的是，不允许这样做。我知道我可以离开网站的根目录，里面装满了小小的
HTML文件，除了重定向到
中的等效页面之外什么都不做
拟议的新层次结构，但是如果
所有可能的话，我很想避免这种情况。
Thanks for the reply - I checked this article out first but didn''t think it
would help me in this instance, due to the caveat at the end:
"Of course, with ASP.NET-level rewriting, the URL rewriting can only happen
if the request is
successfully handed off from IIS to the ASP.NET engine. This naturally
occurs when the user
requests a page with a .aspx extension. However, if you want the person to
be able to enter a
URL that might not actually exist, but would rather rewrite to an existing
ASP.NET page, you
have to either create mock directories and Default.aspx pages, or configure
IIS so that all incoming
requests are blindly routed to the ASP.NET engine."
I can''t reconfigure IIS in this instance because its a public site being
hosted with a commercial ISP who, understandably, won''t allow this. I
realise that I could leave the site''s root directory full of tiny little
HTML files which do nothing other than redirect to the equivalent page in
the proposed new hierarchical structure, but was keen to avoid this if at
all possible.
Application_BeginRequest *是*你在哪里应该这样做。我有几个网站
网站使用网址不存在的页面。例如，
http://mysite.com/mynewsstory.aspx
http://mysite.com/content/content .aspx？storyid = 13 。
这样的东西对你有用。
Sub Application_BeginRequest（ByVal sender As Object，ByVal e As EventArgs）
''在每个请求开始时触发
尝试
''获取用户发布的实际网址
Dim strPath as String = Request.RawUrl
Dim strMyNewPath as String =""
''你的工作在这里将网址更改为
''你真正想要的路径
''...
Context.RewritePath（strMyNewPath）
Catch ex As Exception
''你的异常处理程序在这里
HandleException（）
结束尝试
结束子

Application_BeginRequest *is* where you should do this. I have several web
sites that use urls for pages that don''t exist. For example,
http://mysite.com/mynewsstory.aspx for
http://mysite.com/content/content.aspx?storyid=13.
Something like this should work for you.
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
'' Fires at the beginning of each request
Try
'' get the actual url posted by the user
Dim strPath as String = Request.RawUrl
Dim strMyNewPath as String = ""
'' Do your work here to change the url to
'' the path you really want
'' ...
Context.RewritePath(strMyNewPath)
Catch ex As Exception
'' your exception handler here
HandleException()
End Try
End Sub
