我如何重写一个 url，以便它在地址栏中显示类似 subdomain.example.com/blog 的路径，但显示一个类似 www.example.com/blog/?tag=/subdomain 的页面。
这是我想要发生的事件的过程：
第一个：我导航到 subdomain.example.com/blog 第二个：我被重定向到 www.example.com/blog/?tag=/subdomain 第三个：地址栏中的 url 仍然显示 subdomain.example.com/blog 即使我在 www.example.com/blog/?tag=/subdomain 页面。
我更喜欢使用 HttpContext.RewritePath() 方法
我一直试图在 IHttpModule 中对此进行编码但没有成功
这是我的代码：
using System;
using System.Web;
using System.Net;
using System.Text;
using System.IO;
namespace CommonRewriter
{
public class ParseUrl : IHttpModule
{
public ParseUrl()
{
}
string req = null;
string rep = null;
public String ModuleName
{
get { return "CommonRewriter"; }
}
public void Init(HttpApplication application)
{
application.BeginRequest += new EventHandler(application_BeginRequest);
application.EndRequest += new EventHandler(application_EndRequest);
application.PreRequestHandlerExecute += new EventHandler(application_PreRequestHandlerExecute);
application.AuthorizeRequest += new EventHandler(application_AuthorizeRequest);
}
void application_AuthorizeRequest(object sender, EventArgs e)
{
}
void application_PreRequestHandlerExecute(object sender, EventArgs e)
{
}
private string ParseAndReapply(string textToParse)
{
string final = null;
if (textToParse.Contains("example.com"))
{
string[] splitter = textToParse.Split('.');
if (splitter[0].ToLower() != "www" && (splitter[2].ToLower()).Contains("blog"))
{
string add = splitter[0].Remove(0, 7);
final = ("http://www.example.com/blog/?tag=/" + add);
}
else { final = textToParse; }
}
else { final = textToParse; }
return final;
}
void application_BeginRequest(object sender, EventArgs e)
{
req = HttpContext.Current.Request.Url.AbsoluteUri;
HttpApplication application = (HttpApplication)sender;
HttpContext context = application.Context;
if (req.ToLower().Contains("example.com/blog") && !req.ToLower().Contains("www."))
{
string[] split = req.Split('.');
if (split[1] == "example")
{
rep = ParseAndReapply(req);
context.RewritePath(rep);
context.Response.End();
}
}
}
void application_EndRequest(object sender, EventArgs e)
{
HttpApplication application = (HttpApplication)sender;
HttpContext context = application.Context;
HttpContext context1 = HttpContext.Current;
if (HttpContext.Current.Request.Url.AbsoluteUri.Contains("/?tag=/"))
{
context.RewritePath(req,false);
}
}
}
public void Dispose() { }
}
}
