Get Current.Request.Url in mvc application having a .aspx extension
提问by Manish Gautam
I have a ASP.NET MVC 3 application in which I have to map a request with .aspx extension to another route. what i am trying to do is to get the current request url in application start. but the problem is it runs fine with all urls without .aspx extension but in a url for ex (http://example.com/Products/5/16/Eettafels.aspx) it shows only http://example.com/
我有一个 ASP.NET MVC 3 应用程序，我必须在其中将带有 .aspx 扩展名的请求映射到另一个路由。我想要做的是在应用程序启动时获取当前请求 url。但问题是它在所有没有 .aspx 扩展名的 url 上运行良好，但在 ex ( http://example.com/Products/5/16/Eettafels.aspx)的 url 中它只显示http://example.com/
however with http://example.com/Products/5/16/Eettafelsit shows the correct path ..
但是使用http://example.com/Products/5/16/Eettafels它显示了正确的路径..
All the code is a simple line:
所有代码都是简单的一行：
string currentUrl = HttpContext.Current.Request.Url.ToString().ToLower();
Can any one have any idea what i am doing wrong
任何人都知道我做错了什么吗

Nowadays you can override a Controller method that executes before any Action is called. What I'd then suggest is you keep the current Url like @Ifitkhar suggested in a ViewBag, or TempData, in case you intend on redirecting, then using it later in the Action you want to return afterwards.
如今，您可以覆盖在调用任何 Action 之前执行的 Controller 方法。然后我建议您保留当前的 Url，如在 ViewBag 或 TempData 中建议的 @Ifitkhar，以防您打算重定向，然后在稍后要返回的操作中使用它。
public class ProductsController
{
protected override void OnActionExecuting(ActionExecutingContext filterContext){
TempData["previousUrl"] = HttpContext.Current.Request.Url.AbsoluteUri;
base.OnActionExecuting(filterContext);
}
}
