UrlRewrite 实现二级域名重写（完整解决方案）ASP.NET

微软的URLRewrite能够对URL进行重写，但是也只能对域名之后的部分进行重写，而不能对域名进行重写，如：可将 http://www.sunyet.com/showuser.aspx?us=bbs 重写为 http://www.worldbao.com/suyiming.aspx 但不能将 http://www.worldbao.com/show.aspx?us=bbs 重写为 http://bbs.worldbao.com/

要实现这个功能，首先要做域名泛解析，去域名管理里面的域名解析中添加一个：*.worldbao.com 指向服务器ip。

第二，重写URLRewrite里面的两个方法。

1.BaseModuleRewriter.cs 里面的BaseModuleRewriter_AuthorizeRequest方法

将

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e) { HttpApplication app = (HttpApplication) sender; Rewrite(app.Request.Path, app); }

改为

protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e) { HttpApplication app = (HttpApplication) sender; Rewrite(app.Request.Url.AbsoluteUri, app); }

2， ModuleRewriter.cs 里面的 Rewrite 方法

将

protected override void Rewrite(string requestedPath, System.Web.HttpApplication app) { // log information to the Trace object. app.Context.Trace.Write("ModuleRewriter", "Entering ModuleRewriter"); // get the configuration rules RewriterRuleCollection rules = RewriterConfiguration.GetConfig().Rules; // iterate through each rule... for(int i = 0; i < rules.Count; i++) { // get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory) string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$"; // Create a regex (note that IgnoreCase is set...) Regex re = new Regex(lookFor, RegexOptions.IgnoreCase); // See if a match is found if (re.IsMatch(requestedPath)) { // match found - do any replacement needed string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo)); // log rewriting information to the Trace object app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl); // Rewrite the URL RewriterUtils.RewriteUrl(app.Context, sendToUrl); break; // exit the for loop } } // Log information to the Trace object app.Context.Trace.Write("ModuleRewriter", "Exiting ModuleRewriter"); } }

改为

protected override void Rewrite(string requestedPath, System.Web.HttpApplication app) { // log information to the Trace object. app.Context.Trace.Write("ModuleRewriter", "Entering ModuleRewriter"); // get the configuration rules RewriterRuleCollection rules = RewriterConfiguration.GetConfig().Rules; // iterate through each rule... for(int i = 0; i < rules.Count; i++) { // get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory) string lookFor = "^" + rules[i].LookFor + "$"; // Create a regex (note that IgnoreCase is set...) Regex re = new Regex(lookFor, RegexOptions.IgnoreCase); // See if a match is found if (re.IsMatch(requestedPath)) { // match found - do any replacement needed string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo)); // log rewriting information to the Trace object app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl); // Rewrite the URL RewriterUtils.RewriteUrl(app.Context, sendToUrl); break; // exit the for loop } } // Log information to the Trace object app.Context.Trace.Write("ModuleRewriter", "Exiting ModuleRewriter"); } }

就是将

string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$";

改成了

string lookFor = "^" + rules[i].LookFor + "$";

完成这过程之后将整个项目重新编译一下。

这些都做完之后，

在webconfig配置里面的
<configSections>里面添加：
<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter"/>

在</configSections>下面添加

<RewriterConfig>  <Rules> <RewriterRule> <LookFor>http://www/.worldbao/.com/</LookFor> <SendTo>~/default.aspx</SendTo> </RewriterRule> </Rules>   <Rules> <RewriterRule> <LookFor>http://([a-zA-Z|0-9]+)/.worldbao/.com/</LookFor> <SendTo>/user/user.aspx?us=$1</SendTo> </RewriterRule> </Rules>  </RewriterConfig>

在httpModules里面添加

最后一步

IIS里面添加 ASPNET_ISAPI的通配符应用程序映射

操作方法:IIS站点属性 ->主目录 -> 配置
