ASP.NET Tutorial/Page Lifecycle/URL
Содержание
Determine the current URL:
<source lang="csharp">
Request.RawUrl returns the original URL (before being remapped). Request.Path returns the current URL (after being remapped). Request.AppRelativeCurrentExecutionFilePath returns the application relative URL (after being remapped). <%@ Page Language="C#" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <script runat="server">
void Page_Load()
{
if (String.rupare(Request.Path, Request.RawUrl, true) != 0)
lblMessage.Text = "The URL to this page has changed, " +
"please update your bookmarks.";
}
</script> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server">
<title>Default Page</title>
</head> <body>
<form id="form1" runat="server">
<asp:Label
id="lblMessage"
CssClass="message"
Runat="server" />
The original request was for:
<%=Request.RawUrl%>
which got remapped to:
<%= Request.Path %>
and the application relative version is:
<%= Request.AppRelativeCurrentExecutionFilePath %>
</form>
</body> </html></source>
Remapping URLs in your application"s web configuration file
<source lang="csharp">
Remap the Home.aspx page to the Default.aspx page. File: Web.Config <configuration> <system.web>
<urlMappings>
<add
url="~/Home.aspx"
mappedUrl="~/Default.aspx"/>
</urlMappings>
</system.web> </configuration> The tilde character (~) represents the current application root. A forward slash (/) at the start of a URL represents the website root.</source>
Request.RawUrl
<source lang="csharp">
<%@ Page Language="C#" Trace="true" TraceMode="SortByTime" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="HelloWorldCodeBehind" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server">
