[转]ASP.net 静态化页面 之的URL重写 非常适用

ASP.netURL重写

有关于URL的重写,本文也只是拿来主意。相继有MS的组件“URLRewriter”和在Global.asax里的“Application_BeginRequest()”编码方式,以及IIS里的ISAPI设置。

娜列下来,实现方法也都很简单。

方法一:MS组件

这里也不用详解了,相关请看:

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

用法很简单,只需要把组件URLRewriter.dll拷到应用程序的bin目录下,然后在web.config下加入如下代码:

<configuration></configuration>中加入:

     <configSections>

          <sectionname="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>

   <addverb="*"path="*.aspx"

        type="URLRewriter.RewriterFactoryHandler, URLRewriter"/>

</httpHandlers>

最后在地址栏上键入:http://localhost/Test/2004/12/News.aspx

效果出来了。

上面的<LookFor>~/("d{4})/("d{2})/News".aspx</LookFor>这句这正则表达式URL,即被重写的URL,而<SendTo>~/Default.aspx?ID=$1</SendTo>这一句为原始URL地址。其中的$1为第一个正则表达式值(上面例子为:2004),以此类推,第二个即为$2 

方法二:Application_BeginRequest()

在应用程序中新建一个XML文件,文件内容为:文件名ReWriter.config

<?xmlversion="1.0"encoding="utf-8"?>

<ReWriterUrls>

     <rule>

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

          <new>http://www.cnblogs.com/Default.aspx?id=$2&amp;type=$3</new>

     </rule>

</ReWriterUrls>

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

              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

              {

              }
