asp.net 获取URL的可靠方法

发布时间:2019-09-03编辑:脚本学堂
有时候,HttpContext.Current.Request.Url.ToString() 并不可靠,本文为大家介绍asp.net获取url的可靠方法,供大家学习参考。

假如,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=??ê?

正确的获取方法:
HttpContext.Current.Request.Url.PathAndQuery

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

复制代码 代码示例:
Request.ApplicationPath: /testweb
Request.CurrentExecutionFilePath: /testweb/default.aspx
Request.FilePath: /testweb/default.aspx
Request.Path: /testweb/default.aspx
Request.PhysicalApplicationPath: E:WWWtestwebRequest.PhysicalPath: E:WWWtestwebdefault.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 代码示例:

<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;
thisURL = document.URL;
thisHREF = document.location.href;
thisSLoc = self.location.href;
<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;
thisPLoc = parent.document.location;
thisTHost = top.location.hostname;
thisHost = location.hostname;
<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>
