ASP.net的RUL重寫

asp.net

有關於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裡的“Application_BeginRequest()”編碼方式，以及IIS裡的ISAPI設定。

娜列下來，實現方法也都很簡單。

 

方法一：MS組件

這裡也不用詳解了，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拷到應用程式的bin目錄下，然後在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>

 

然後在<system.web></system.web>中加入：

<httpHandlers>

   <add verb="*" path="*.aspx"

        type="URLRewriter.RewriterFactoryHandler, URLRewriter" />

</httpHandlers>

 

最後在地址欄上鍵入：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RegexURL，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Regex值（上面例子為：2004），以此類推，第二個即為$2

方法二：Application_BeginRequest()

在應用程式中建立一個XML檔案，檔案內容為：檔案名稱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>

在Global.asax檔案中的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

              {

              }

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

效果出來了。
