http://1234.abc.com 重写为 http://www.abc.com/show.aspx?id=1234。 要实现这个功能，前提条件就是 www.abc.com 是泛解析的，再就是要修改一下URLRewriter了。 总共要修改2个文件 1.BaseModuleRewriter.cs  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); } 就是将 app.Request.Path 替换成了 app.Request.Url.AbsoluteUri 2.ModuleRewriter.cs 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) + "$"; // Create a regex (note that IgnoreCase is set) Regex re = new Regex(lookFor, RegexOptions.IgnoreCase); // See if a match is found if (re.IsMatch(requestedPath))   { // match found - do any replacement needed string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo)); // log rewriting information to the Trace object app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl); // Rewrite the URL RewriterUtils.RewriteUrl(app.Context, sendToUrl); break; // exit the for loop  } } 改为 for(int i = 0; i < rules.Count; i++) { // get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory) string lookFor = "^" + rules[i].LookFor + "$"; // 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 } } 将 string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$"; 改成了 string lookFor = "^" + rules[i].LookFor + "$"; 完成这2处改动之后重新编译项目，将生成的dll复制到bin目录下。 再就是写web.config里的重写正则了 <RewriterRule> <LookFor>http://(/d+)/.abc/.comLookFor> <SendTo>/show.aspx?id=$1SendTo> RewriterRule>现在你在IE地址栏输入http://1234.abc.com，就可以看到http://www.abc.com/show.aspx?id=1234了 源代码网推荐 源代码网供稿. |
