ASP.NET中实现二级或多级域名(修改UrlRewrite) (转)
大家应该知道,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://http://www.abc.com//1234/  重写为 http://www.abc.com/show.aspx?id=1234  但不能将 
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 http://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)
protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e) 
![]() {
        { 
![]() HttpApplication app = (HttpApplication) sender;
            HttpApplication app = (HttpApplication) sender; 
![]() Rewrite(app.Request.Path, app);
            Rewrite(app.Request.Path, app); 
![]() }
        } 
改为
![]() protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e) 
![]() {
        { 
![]() HttpApplication app = (HttpApplication) sender;
            HttpApplication app = (HttpApplication) sender; 
![]() Rewrite(app.Request.Url.AbsoluteUri, app);
            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++)
for(int i = 0; i < rules.Count; i++) 
![]() {
            { 
![]() // get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory)
                // 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) + "$";
                string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$"; 
![]() 
 
![]() // Create a regex (note that IgnoreCase is set
                // Create a regex (note that IgnoreCase is set![]() )
) 
![]() Regex re = new Regex(lookFor, RegexOptions.IgnoreCase);
                Regex re = new Regex(lookFor, RegexOptions.IgnoreCase); 
![]() 
 
![]() // See if a match is found
                // See if a match is found 
![]() if (re.IsMatch(requestedPath))
                if (re.IsMatch(requestedPath)) 
![]() {
                { 
![]() // match found - do any replacement needed
                    // match found - do any replacement needed 
![]() string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo));
                    string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo)); 
![]() 
 
![]() // log rewriting information to the Trace object
                    // log rewriting information to the Trace object 
![]() app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl);
                    app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl); 
![]() 
 
![]() // Rewrite the URL
                    // Rewrite the URL 
![]() RewriterUtils.RewriteUrl(app.Context, sendToUrl);
                    RewriterUtils.RewriteUrl(app.Context, sendToUrl); 
![]() break;        // exit the for loop
                    break;        // exit the for loop 
![]() }
                } 
![]() }
            } 
改为
![]() for(int i = 0; i < rules.Count; i++)
for(int i = 0; i < rules.Count; i++) 
![]() {
            { 
![]() // get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory)
                // get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory) 
![]() string lookFor = "^" + rules[i].LookFor + "$";
                string lookFor = "^" + rules[i].LookFor + "$"; 
![]() 
 
![]() // Create a regex (note that IgnoreCase is set
                // Create a regex (note that IgnoreCase is set![]() )
) 
![]() Regex re = new Regex(lookFor, RegexOptions.IgnoreCase);
                Regex re = new Regex(lookFor, RegexOptions.IgnoreCase); 
![]() 
 
![]() // See if a match is found
                // See if a match is found 
![]() if (re.IsMatch(requestedPath))
                if (re.IsMatch(requestedPath)) 
![]() {
                { 
![]() // match found - do any replacement needed
                    // match found - do any replacement needed 
![]() string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo));
                    string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo)); 
![]() 
 
![]() // log rewriting information to the Trace object
                    // log rewriting information to the Trace object 
![]() app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl);
                    app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl); 
![]() 
 
![]() // Rewrite the URL
                    // Rewrite the URL 
![]() RewriterUtils.RewriteUrl(app.Context, sendToUrl);
                    RewriterUtils.RewriteUrl(app.Context, sendToUrl); 
![]() break;        // exit the for loop
                    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>
<RewriterRule>
![]() <LookFor>http://(\d+)\.abc\.com/</LookFor>
            <LookFor>http://(\d+)\.abc\.com/</LookFor>
![]() <SendTo>/show.aspx?id=$1</SendTo>
            <SendTo>/show.aspx?id=$1</SendTo>
![]() </RewriterRule>
        </RewriterRule>
好了大功告成,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
的结果了
