波兰美女菲古拉与600余男子大战8小时,新安江第一小学,散文赏析
第一种是在页面global.asax中，相关代码如下：
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);
}
第二种方法是在httpmodule.cs中，代码如下：
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;
}
}
