• 【IHttpHandler】在ASP.Net2.0中使用UrlRewritingNet实现链接重写


    很多时候我们需要链接转向(Url Rewriting),例如二级域名转向、文章访问链接等场合。
    让我们看两个例子:
    1 你现在看到的当前作者的博客园的域名:
    http://jx270.cnblogs.com/ 实际上是 http://www.cnblogs.com/jx270 的一种链接重写(Url Rewriting)。
    2 codeproject上的文章,我们获取的地址都是以文章主要关键字做的网页名称:
    http://www.codeproject.com/cs/webservices/wsdlparser.asp 
    个人觉得实际的文章链接可能是如下格式(纯属猜想)
    http://www.codeproject.com/news.asp?id=123456  
    那么如何在Asp.net2.0中如何实现链接重写呢?
    可以采用UrlRewritingNet.UrlRewriter.dll来轻松实现
    UrlRewritingNet.UrlRewriter.dll 可从其官方网站下载:http://www.urlrewriting.net
    我们要做的就是进行Web.Config文件的设置

    0 设置之前需要添加引用:UrlRewritingNet.UrlRewriter.dll

    1 <configSections>间添加:
      <configSections>
      <section name="urlrewritingnet" restartOnExternalChanges="true" requirePermission="false" type="UrlRewritingNet.Configuration.UrlRewriteSection, UrlRewritingNet.UrlRewriter"/>
    </configSections>

    2   添加httpModules
    <httpModules>
          <add name="UrlRewriteModule" type="UrlRewritingNet.Web.UrlRewriteModule, UrlRewritingNet.UrlRewriter"/>
      </httpModules>


    3 添加链接重写的设置
    <urlrewritingnet rewriteOnlyVirtualUrls="true" contextItemsPrefix="QueryString" defaultPage="default.aspx" defaultProvider="RegEx" xmlns="http://www.urlrewriting.net/schemas/config/2006/07">
      <rewrites>
       <add name="Rewrite1" virtualUrl="^http://(.*)/UrlRewritingTest/test.aspx" rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="~/default.aspx" rewrite="Domain" ignoreCase="true"/>
       <add name="Rewrite2" virtualUrl="^http://(.*)/UrlRewritingTest/test1.aspx" rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="~/info.aspx?year=2007&amp;month=3&amp;day=9" rewrite="Domain" ignoreCase="true"/>
      </rewrites>
    </urlrewritingnet>

    完整的一个Web.Config文件

    <?xml version="1.0"?>
    
    <configuration>
    
        <configSections>
    
            <section name="urlrewritingnet" restartOnExternalChanges="true" requirePermission="false" type="UrlRewritingNet.Configuration.UrlRewriteSection, UrlRewritingNet.UrlRewriter"/>
    
        </configSections>
    
        <urlrewritingnet rewriteOnlyVirtualUrls="true" contextItemsPrefix="QueryString" defaultPage="default.aspx" defaultProvider="RegEx" xmlns="http://www.urlrewriting.net/schemas/config/2006/07">
    
            <rewrites>
    
                <add name="Rewrite1" virtualUrl="^http://(.*)/UrlRewritingTest/test.aspx" rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="~/default.aspx" rewrite="Domain" ignoreCase="true"/>
    
                <add name="Rewrite2" virtualUrl="^http://(.*)/UrlRewritingTest/test1.aspx" rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="~/info.aspx?year=2007&amp;month=3&amp;day=9" rewrite="Domain" ignoreCase="true"/>
    
                <add name="Rewrite3" virtualUrl="^http://(.*)/UrlRewritingTest/test(d{4})(d{2})(d{2}).aspx" rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="~/info.aspx?year=$2&amp;month=$3&amp;day=$4" rewrite="Domain" ignoreCase="true"/>
    
                <add name="Rewrite4" virtualUrl="^http://(.*)/UrlRewritingTest/(d{4})/(d{2})/(d{2})/info.aspx" rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="~/info.aspx?year=$2&amp;month=$3&amp;day=$4" rewrite="Domain" ignoreCase="true"/>
    
          <add name="Rewrite5" virtualUrl="^http://(.*)/UrlRewritingTest/stock(d{6}).aspx" rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="~/stockinfo.aspx?code=$2" rewrite="Domain" ignoreCase="true"/>
    
            </rewrites>
    
        </urlrewritingnet>
    
        <appSettings/>
    
        <system.web>
    
            <httpModules>
    
                <add name="UrlRewriteModule" type="UrlRewritingNet.Web.UrlRewriteModule, UrlRewritingNet.UrlRewriter"/>
    
            </httpModules>
    
            <compilation debug="true"/>
    
      </system.web>
    
    </configuration>

    示例程序
    我们做了一个按查询字符串的输入显示对应日期的页面info.aspx

        protected void Page_Load(object sender, EventArgs e)
    
        {
    
            string strYear = Request.QueryString["year"].ToString();
    
            string strMonth = Request.QueryString["month"].ToString();
    
            string strDay = Request.QueryString["day"].ToString();
    
            Response.Write(string.Format("你输入的日期是{0}年{1}月{2}日",strYear,strMonth,strDay));
    
        }

    常规访问方式:http://localhost/UrlRewritingTest/info.aspx?year=2007&month=03&day=08

    页面重写方式1:http://localhost/UrlRewritingTest/test20070308.aspx

    页面重写方式2:http://localhost/UrlRewritingTest/2007/03/08/info.aspx

    大家可以看到实际的访问效果是一致的。


    示例文件中还有一个股票信息查看的例子:
    http://localhost/UrlRewritingTest/stock600616.aspx = http://localhost/UrlRewritingTest/stockinfo.aspx?code=600616


    示例程序下载:/Files/heekui/UrlRewritingTest.rar
