HttpContext.Current.Request.Url.ToString() 并不可靠。

如果当前URL为
http://localhost/search.aspx?user=http://csharp.xdowns.com&tag=%BC%BC%CA%F5

通过HttpContext.Current.Request.Url.ToString()获取到的却是

http://localhost/search.aspxuser=http://csharp.xdowns.com&tag=¼¼Êõ

正确的方法是：

复制代码 代码如下:

HttpContext.Current.Request.Url.PathAndQuery

1、通过ASP.NET获取
如果测试的url地址是http://www.test.com/testweb/default.aspx, 结果如下：

复制代码 代码如下:

Request.ApplicationPath: /testweb
Request.CurrentExecutionFilePath: /testweb/default.aspx
Request.FilePath: /testweb/default.aspx
Request.Path: /testweb/default.aspx
Request.PhysicalApplicationPath: E:\WWW\testwebRequest.PhysicalPath: E:\WWW\testweb\default.aspx
Request.RawUrl: /testweb/default.aspx
Request.Url.AbsolutePath: /testweb/default.aspx
Request.Url.AbsoluteUrl: http://www.test.com/testweb/default.aspx
Request.Url.Host: www.test.com
Request.Url.LocalPath: /testweb/default.aspx

2、通过JS获取

复制代码 代码如下:

thisDLoc = document.location;

thisURL = document.URL;

thisHREF = document.location.href;

thisSLoc = self.location.href;

thisTLoc = top.location.href;

thisPLoc = parent.document.location;

thisTHost = top.location.hostname;

thisHost = location.hostname;
