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://heekui.cnblogs.com 实际上是 http://www.cnblogs.com/heekui 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&month=3&day=9" rewrite="Domain" ignoreCase="true"/>
</rewrites>
</urlrewritingnet>
完整的一个Web.Config文件
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
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。
