1:asp.net1.1中重写中可删节的问题!!!
如以下的正则表达式:
<Rules>
<RewriterRule>
<LookFors>
<LookFor>~/(\d{4})/(\d{2})\.html</LookFor>---------<1>
<LookFor>~/(\d{4})/(\d{2})/</LookFor>--------------<2>
<LookFor>~/(\d{4})/(\d{2})</LookFor>-----------<3>
<LookFor>~/(\d{4})/(\d{2})/index.html</LookFor>----<4>
</LookFors>
<SendTo>~/Pro.aspx?year=$1&month=$2</SendTo>
</RewriterRule>
</Rules>
其中的1,4可以正常映射到对应的页面
可2,3则会出现http404错误!!!
其原因在于IIS本身的处理流程,解决办法则是在网站自己重写404处理错误!!!
1:自定义处理404错误的URL(在IIS中配置,在web.config中的配置对重写无用)
2:在System.Web节中添加如下节:
<httpHandlers>
<add verb="*" path="404.aspx" type="lt.Http404,lt"></add>
</httpHandlers>
<httpModules>
<add type="lt.ReWriteModule,lt" name="ModuleRewriter" />
</httpModules>
源代码如下:
public class Http404:System.Web.IHttpHandler
{
public Http404()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
#region IHttpHandler 成员
public void ProcessRequest(System.Web.HttpContext context)
{
// TODO: 添加 Http404.ProcessRequest 实现
string errorPath=context.Request.RawUrl.Split(new char[]{';'})[1];
string appPath=context.Request.ApplicationPath;
int ipos=errorPath.IndexOf(appPath);
string url=errorPath.Substring(ipos+appPath.Length );
// if(!url.EndsWith("/"))
// {
// url+="/";
// }
// url+="index.html";
// context.Response.Write(url);
// context.RewritePath(url);
//context.Response.Write(url);
url="~"+url;
string newUrl =lt.ReWriteModule.GetUrl(context,url);
//context.Response.Write(newUrl);
if (newUrl != null)
{
//cxt.Response.Filter = new ResponseFilter(cxt.Response.Filter,cxt.Request.Path);
context.Response.Write("请求的路径:" + url);
context.Response.Write("<BR>");
context.Response.Write("转向的目的URL:" + newUrl);
context.Response.Write("<BR>");
context.RewritePath(newUrl);
}
else
{
context.Response.Write("你请求的资源不存在!!");
context.Response.End ();
}
}
public bool IsReusable
{
get
{
// TODO: 添加 Http404.IsReusable getter 实现
return false;
}
}
///////////////配置节处理中的httpModule如下:
public class ReWriteModule:System.Web.IHttpModule
{
public ReWriteModule()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
#region IHttpModule 成员
public void Init(System.Web.HttpApplication context)
{
// TODO: 添加 ReWriteModule.Init 实现
context.BeginRequest+=new EventHandler(this.ReWrite);
