Introduction to implementing pseudo-static pages in C #

First, in the global. asax page, the related code is as follows::
Copy codeThe Code is as follows:
Void Application_BeginRequest (object sender, EventArgs e)
{
HttpContext context = (HttpApplication) sender). Context;
String oldurl = context. Request. Path. ToLower ();
If (oldurl. indexOf ("-")> 0 & oldurl. indexOf (". ") =-1) | (oldurl. indexOf ("-")> 0 & oldurl. indexOf ("aspx")> 0 ))
{
String [] url = oldurl. Substring (oldurl. LastIndexOf ("/") + 1). Replace (". aspx", ""). Split ('-');
String path = oldurl. Substring (0, oldurl. LastIndexOf ("/") + 1 );
// File
String file = url [0];
File = file. Replace ("about", "detail ");
File = file. Replace ("news", "list ");
File = file. Replace ("down", "detail ");
File = file. Replace ("case", "album ");
File = file. Replace ("contact", "detail ");
// Query
String query = "";
For (int I = 1; I <url. Length; I ++)
{
If (url [I]! = "")
{
Switch (I)
{
Case 1:
Query + = "id =" + url [I];
Break;
Case 2:
Query + = "& page =" + url [I];
Break;
Case 3:
Query + = "& key =" + url [I];
Break;
Case 4:
Query + = "& v1 =" + url [I];
Break;
Case 5:
Query + = "& v2 =" + url [I];
Break;
Case 6:
Query + = "& v3 =" + url [I];
Break;
Case 7:
Query + = "& v4 =" + url [I];
Break;
Case 8:
Query + = "& v5 =" + url [I];
Break;
Case 9:
Query + = "& v6 =" + url [I];
Break;
Case 10:
Query + = "& v7 =" + url [I];
Break;
}
}
}
// Newurl
String newurl = path + file + ". aspx? "+ Query;
If (context. Request. ServerVariables ["QUERY_STRING"]! = Null & context. Request. ServerVariables ["QUERY_STRING"]! = "")
Newurl + = "&" + context. Request. ServerVariables ["QUERY_STRING"];
// Response. Write (newurl );
Context. RewritePath (newurl );
}

The second method is in HttpModule. cs, the Code is as follows::
Copy codeThe Code is as follows:
Public class HttpModule: IHttpModule
{
Private const RegexOptions regexOptions = RegexOptions. IgnoreCase | RegexOptions. Compiled;
Private static readonly Regex regexFileName = new Regex (@".*? /([^./] *) \. Aspx (. *) ", regexOptions );
Private static readonly Regex regexRewritePath = new Regex (@ "^ .*? /(\ W *)(-? (\ W +)-([\ w, \ |, %] +) + \. aspx ", regexOptions );
Public void Dispose ()
{
}
Public void Init (HttpApplication httpApplication)
{
HttpApplication. BeginRequest + = ReUrl_BeginRequest;
}
Private static void ReUrl_BeginRequest (object sender, EventArgs e)
{
Globals. Catch (
() =>
{
Var context = (HttpApplication) sender). Context;
Var request = context. Request;
Var url = request. Url;
If (! VerifyUrl (url ))
{
String input = url. PathAndQuery. ToLower ();
// Loger. Debug ("PathAndQuery -->" + input );
// Loger. Debug ("AbsolutePath -->" + url. AbsolutePath );
// Loger. Debug ("AbsoluteUri -->" + url. AbsoluteUri );
// Loger. Debug ("DnsSafeHost -->" + url. DnsSafeHost );
// Loger. Debug ("LocalPath -->" + url. LocalPath );
// Loger. Debug ("AppDomain. CurrentDomain. BaseDirectory -->" + AppDomain. CurrentDomain. BaseDirectory );
// Loger. Debug ("Globals. GlobalsVirtualFilePath -->" + Globals. GlobalsVirtualFilePath );
If (input. StartsWith (Globals. GlobalsVirtualFilePath ))
Input = input. Remove (0, Globals. GlobalsVirtualFilePath. Length );
String viewmode = Globals. ViewMode;
Var themeName = request. QueryString ["theme"]? "";
If (string. IsNullOrEmpty (themeName ))
{
ThemeName = Globals. ThemeName;
}
If (input = "/")
Input = "/index. aspx ";
If (viewmode = "Rewrite ")
{
Loger. Debug ("now input -->" + input );
Match match = regexRewritePath. Match (input );
If (match. Success & match. Groups. Count = 5)
{
Var captures3 = match. Groups [3]. Captures;
Var captures4 = match. Groups [4]. Captures;
Var itemCount = match. Groups [3]. Captures. Count;
Var list = new List <string> ();
For (var I = 0; I <itemCount; I ++)
{
List. Add (string. Concat (captures3 [I]. Value, "=", captures4 [I]. Value ));
}
Context. RewritePath (Globals. AspxFileUrl (themeName, match. Groups [1]. Value + ". aspx? "+ String. Join (" & ", list. ToArray ())));
Return;
}
}
Var fileName = regexFileName. Match (request. Path. ToLower (). Groups [1]. ToString ();
If (string. IsNullOrEmpty (fileName ))
Return;
New ConvertTheme (context)
{
ThemeName = themeName,
ViewMode = viewmode
}. Display (fileName );
}
});
}
Private static bool VerifyUrl (Uri uri)
{
Var url = uri. AbsolutePath. ToLower ();
If (url. StartsWith (Globals. GlobalsVirtualFilePath ))
Url = url. Remove (0, Globals. GlobalsVirtualFilePath. Length );
Return uri. IsFile
| Url. IndexOf ("site ")! =-1
| Url. IndexOf ("sys ")! =-1
| Url. IndexOf ("html ")! =-1
| Url. IndexOf ("user ")! =-1
| Url. IndexOf ("bbs ")! =-1
| Url. IndexOf ("_ module. aspx ")! =-1
| Url. IndexOf ("webresource. axd ")! =-1
| Url. IndexOf ("scriptresource. axd ")! =-1;
}
}
