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：HttpContext.Current.Request.Url.PathAndQuery
Request.Url.PathAndQuery
string 类型。等于 Request.Url.AbsolutePath 和 Request.Url.Query 相加。
Request.Url.AbsolutePath
string 类型。指当前页面 URL 的绝对路径，不包括查询字符串部分。
示例：/test/Default.aspx
Request.Url.Query
string 类型。指当前页面 URL 的查询字符串，从“?”开始。
示例：?a=1&b=2
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：
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
| URL | http://localhost:1897/News/Press/Content.aspx/123?id=1#toc |
| Request.ApplicationPath | / |
| Request.PhysicalPath | D:\Projects\Solution\web\News\Press\Content.aspx |
| System.IO.Path.GetDirectoryName(Request.PhysicalPath) | D:\Projects\Solution\web\News\Press |
| Request.PhysicalApplicationPath | D:\Projects\Solution\web\ |
| System.IO.Path.GetFileName(Request.PhysicalPath) | Content.aspx |
| Request.CurrentExecutionFilePath | /News/Press/Content.aspx |
| Request.FilePath | /News/Press/Content.aspx |
| Request.Path | /News/Press/Content.aspx/123 |
| Request.RawUrl | /News/Press/Content.aspx/123?id=1 |
| Request.Url.AbsolutePath | /News/Press/Content.aspx/123 |
| Request.Url.AbsoluteUri | http://localhost:1897/News/Press/Content.aspx/123?id=1 |
| Request.Url.Scheme | http |
| Request.Url.Host | localhost |
| Request.Url.Port | 1897 |
| Request.Url.Authority | localhost:1897 |
| Request.Url.LocalPath | /News/Press/Content.aspx/123 |
| Request.PathInfo | /123 |
| Request.Url.PathAndQuery | /News/Press/Content.aspx/123?id=1 |
| Request.Url.Query | ?id=1 |
| Request.Url.Fragment | |
| Request.Url.Segments | / 123 |
2、通过JS获取
<table width=100% cellpadding=0 cellspacing=0 border=0 >
<script>
thisURL = document.URL;
thisHREF = document.location.href;
thisSLoc = self.location.href;
thisDLoc = document.location;
strwrite = "<tr><td valign=top>thisURL: </td><td>[" + thisURL + "]</td></tr>"
strwrite += "<tr><td valign=top>thisHREF: </td><td>[" + thisHREF + "]</td></tr>"
strwrite += "<tr><td valign=top>thisSLoc: </td><td>[" + thisSLoc + "]</td></tr>"
strwrite += "<tr><td valign=top>thisDLoc: </td><td>[" + thisDLoc + "]</td></tr>"
document.write( strwrite );
</script>
thisDLoc = document.location; <BR>
thisURL = document.URL; <BR>
thisHREF = document.location.href; <BR>
thisSLoc = self.location.href;<BR>
<script>
thisTLoc = top.location.href;
thisPLoc = parent.document.location;
thisTHost = top.location.hostname;
thisHost = location.hostname;
strwrite = "<tr><td valign=top>thisTLoc: </td><td>[" + thisTLoc + "]</td></tr>"
strwrite += "<tr><td valign=top>thisPLoc: </td><td>[" + thisPLoc + "]</td></tr>"
strwrite += "<tr><td valign=top>thisTHost: </td><td>[" + thisTHost + "]</td></tr>"
strwrite += "<tr><td valign=top>thisHost: </td><td>[" + thisHost + "]</td></tr>"
document.write( strwrite );
</script>
thisTLoc = top.location.href; <BR>
thisPLoc = parent.document.location; <BR>
thisTHost = top.location.hostname; <BR>
thisHost = location.hostname;<BR>
<script>
tmpHPage = thisHREF.split( "/" );
thisHPage = tmpHPage[ tmpHPage.length-1 ];
tmpUPage = thisURL.split( "/" );
thisUPage = tmpUPage[ tmpUPage.length-1 ];
strwrite = "<tr><td valign=top>thisHPage: </td><td>[" + thisHPage + "]</td></tr>"
strwrite += "<tr><td valign=top>thisUPage: </td><td>[" + thisUPage + "]</td></tr>"
document.write( strwrite );
</script><tr><td>
