ASP.net的RUL重寫<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

?

有關于URL的重寫，本文也只是拿來主意。相繼有MS的組件“URLRewriter”和在Global.asax里的“Application_BeginRequest()”編碼方式，以及IIS里的ISAPI設置。

娜列下來，實現方法也都很簡單。

?

方法一：MS組件

這里也不用詳解了，相關請看：

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

用法很簡單，只需要把組件URLRewriter.dll拷到應用程序的bin目錄下，然后在web.config下加入如下代碼：

在<configuration></configuration>中加入：

???? <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>

然后在<system.web></system.web>中加入：

<httpHandlers>

?? <add verb="*" path="*.aspx"

??????? type="URLRewriter.RewriterFactoryHandler, URLRewriter" />

</httpHandlers>

?

最后在地址欄上鍵入：http://localhost/Test/2004/12/News.aspx

效果出來了。

上面的<LookFor>~/(\d{4})/(\d{2})/News\.aspx</LookFor>這句這正則表達式URL，即被重寫的URL，而<SendTo>~/Default.aspx?ID=$1</SendTo>這一句為原始URL地址。其中的$1為第一個正則表達式值（上面例子為：2004），以此類推，第二個即為$2?

?

方法二：Application_BeginRequest()

在應用程序中新建一個XML文件，文件內容為：文件名ReWriter.config

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

<ReWriterUrls>

???? <rule>

???? ???? <old>(.*)/News/(\d{4})/Default\.aspx</old>

???? ???? <new>../../Default.aspx?id=$2&amp;type=$3</new>

???? </rule>

</ReWriterUrls>

在Global.asax文件中的Application_BeginRequest(Object sender, EventArgs e)加入代碼：

???????? ???? try

????????????? {

????????????? ???? string path=Server.MapPath("~/ReWriter.config");

????????????? ???? XPathDocument myXPathDocument = new XPathDocument(path);

????????????? ???? XPathNavigator myXPathNavigator = myXPathDocument.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

????????????? {

????????????? }

?

最后在地址欄上鍵入：http://localhost/Test/News/2004/Default.aspx

效果出來了。
