Implementation of pseudo-static page in C # two ways to introduce _ practical skills

The first is in the page global.asax, the relevant code is as follows：

Copy Code code 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 approach is in HttpModule.cs, where the code is as follows：

Copy Code code 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;
}
}
