ASP.net's Rul rewrite

The article is just an idea for rewriting URLs. A succession of MS Components "Urlrewriter" and "Application_BeginRequest ()" Encoding in Global.asax, as well as ISAPI settings in IIS.

Donna listed, the implementation method is also very simple.

Method One: Ms components

Here also do not need to explain, the relevant see:

Http://www.microsoft.com/china/msdn/library/webservices/asp.net/URLRewriting.mspx

The usage is simple, just copy the component URLRewriter.dll to the application's Bin directory, and then add the following code under Web.config:

Add in <configuration></configuration>:

<configSections>

<section name= "Rewriterconfig" type= "URLRewriter.Config.RewriterConfigSerializerSectionHandler, Urlrewriter"/ >

</configSections>

<RewriterConfig>

<Rules>

<RewriterRule>

<lookfor>~/(\d{4})/(\d{2})/default\.aspx</lookfor>

<SendTo>~/Default.aspx?ID=$1</SendTo>

</RewriterRule>

</Rules>

</RewriterConfig>

Then add in <system.web></system.web>:

<add verb= "*" Path= "*.aspx"

Type= "Urlrewriter.rewriterfactoryhandler, Urlrewriter"/>

Finally, type on the address bar: http://localhost/Test/2004/12/News.aspx

The effect came out.

The above <lookfor>~/(\d{4})/(\d{2})/news\.aspx</lookfor> This regular expression URL, which is the overridden URL, and <sendto>~/ Default.aspx?id=$1</sendto> This sentence is the original URL address. Where is the first regular expression value (the example above is: 2004), and so on, the second is $

Method Two: Application_BeginRequest ()

Create a new XML file in your application that contains the file name: Rewriter.config

<?xml version= "1.0" encoding= "Utf-8"?>

<ReWriterUrls>

<rule>

<old> (. *)/news/(\d{4})/default\.aspx</old>

<new> /.. /default.aspx?id=$2&type=$3</new>

</rule>

</ReWriterUrls>

In the Global.asax file, add the code in the Application_BeginRequest (Object sender, EventArgs e):

Try

{

String Path=server.mappath ("~/rewriter.config");

Xpathdo***ent myxpathdo***ent = new Xpathdo***ent (path);

XPathNavigator myxpathnavigator = Myxpathdo***ent. CreateNavigator ();

XPathNodeIterator myxpathnodeiterator = Myxpathnavigator.select ("//rule");

System.Text.RegularExpressions.Regex Oreg;

String Rewriteurl;

while (Myxpathnodeiterator.movenext ())

{

Oreg=new Regex (Onode.selectsinglenode ("Url/text ()"). Value);

XPathNavigator nav2 = MyXPathNodeIterator.Current.Clone ();

String Oldstring= "", newstring= "";

XPathNodeIterator it2 = nav2. Select ("old");

while (it2. MoveNext ())

{

oldstring = It2. Current.value;

Break

}

It2 = nav2. Select ("new");

while (it2. MoveNext ())

{

NewString = It2. Current.value;

Break

}

if (oldstring!= "" && newstring!= "")

{

Oreg = new System.Text.RegularExpressions.Regex (oldstring);

if (Oreg.ismatch (Request.Url.ToString ()))

{

Rewriteurl = Oreg.replace (Request.Url.ToString (), newstring);

HttpContext.Current.RewritePath (Rewriteurl);

Break

}

}

}

}

Catch

{

}
