UrlRewrite 实现 二级域名 重写（完整解决方案） 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.worldbao.com/showuser.aspx?us=suyiming 重写为 http://www.worldbao.com/suyiming.aspx 但不能将 http://www.worldbao.com/show.aspx?us=suyiming 重写为 http://suyiming.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
view plaincopy to clipboardprint?
protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication) sender;
Rewrite(app.Request.Path, app);
}
protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication) sender;
Rewrite(app.Request.Path, app);
}
改为
view plaincopy to clipboardprint?
protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication) sender;
Rewrite(app.Request.Url.AbsoluteUri, app);
}
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
view plaincopy to clipboardprint?
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) + "$";
// Create a regex (note that IgnoreCase is set...)
Regex re = new Regex(lookFor, RegexOptions.IgnoreCase);
// See if a match is found
if (re.IsMatch(requestedPath))
{
// match found - do any replacement needed
string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo));
// log rewriting information to the Trace object
app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl);
// Rewrite the URL
RewriterUtils.RewriteUrl(app.Context, sendToUrl);
break; // exit the for loop
}
}
// Log information to the Trace object
app.Context.Trace.Write("ModuleRewriter", "Exiting ModuleRewriter");
}
}
protected override void Rewrite(string requestedPath, System.Web.HttpApplication app)
{
// log information to the Trace object.
app.Context.Trace.Write("ModuleRewriter", "Entering ModuleRewriter");
// get the configuration rules
RewriterRuleCollection rules = RewriterConfiguration.GetConfig().Rules;
// iterate through each rule...
for(int i = 0; i < rules.Count; i++)
{
// get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory)
string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$";
// 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
view plaincopy to clipboardprint?
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 + "$";
// Create a regex (note that IgnoreCase is set...)
Regex re = new Regex(lookFor, RegexOptions.IgnoreCase);
// See if a match is found
if (re.IsMatch(requestedPath))
{
// match found - do any replacement needed
string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo));
// log rewriting information to the Trace object
app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl);
// Rewrite the URL
RewriterUtils.RewriteUrl(app.Context, sendToUrl);
break; // exit the for loop
}
}
// Log information to the Trace object
app.Context.Trace.Write("ModuleRewriter", "Exiting ModuleRewriter");
}
}
protected override void Rewrite(string requestedPath, System.Web.HttpApplication app)
{
// log information to the Trace object.
app.Context.Trace.Write("ModuleRewriter", "Entering ModuleRewriter");
// get the configuration rules
RewriterRuleCollection rules = RewriterConfiguration.GetConfig().Rules;
// iterate through each rule...
for(int i = 0; i < rules.Count; i++)
{
// get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory)
string lookFor = "^" + rules[i].LookFor + "$";
// 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：
view plaincopy to clipboardprint?
<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter"/>
<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter"/>
在</configSections>下面添加
view plaincopy to clipboardprint?
<RewriterConfig>
<!-- 处理默认首页失败-->
<Rules>
<RewriterRule>
<LookFor>http://www/.worldbao/.com/</LookFor>
<SendTo>~/default.aspx</SendTo>
</RewriterRule>
</Rules>
<!-- 处理默认首页失败-->
<!--二级域名正则-->
<Rules>
<RewriterRule>
<LookFor>http://([a-zA-Z|0-9]+)/.worldbao/.com/</LookFor>
<SendTo>/user/user.aspx?us=$1</SendTo>
</RewriterRule>
</Rules>
<!--二级域名正则-->
</RewriterConfig>
<RewriterConfig>
<!-- 处理默认首页失败-->
<Rules>
<RewriterRule>
<LookFor>http://www/.worldbao/.com/</LookFor>
<SendTo>~/default.aspx</SendTo>
</RewriterRule>
</Rules>
<!-- 处理默认首页失败-->
<!--二级域名正则-->
<Rules>
<RewriterRule>
<LookFor>http://([a-zA-Z|0-9]+)/.worldbao/.com/</LookFor>
<SendTo>/user/user.aspx?us=$1</SendTo>
</RewriterRule>
</Rules>
<!--二级域名正则-->
</RewriterConfig>
在httpModules里面添加
view plaincopy to clipboardprint?
<httpModules>
<add type="URLRewriter.ModuleRewriter, URLRewriter" name="ModuleRewriter"/>
</httpModules>
<httpModules>
<add type="URLRewriter.ModuleRewriter, URLRewriter" name="ModuleRewriter"/>
</httpModules>
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
点击插入按键
选择或输入C:/WINDOWS/Microsoft.NET/Framework/v1.1.4322/aspnet_isapi.dll
取消"确认文件是否存在"前的钩. 确定
ok,现在输入http://suyiming.worldbao.com/就可以看到效果了
