asp.net中获取当前url的方法  

2009-11-27 10:47:48|  分类: .NET/C# |  标签: |举报 |字号 订阅

  下载LOFTER 我的照片书  |

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.PathAndQuery1、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

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>

=================

获取IP

1、ASP.NET中获取

获取服务器的IP地址:

using System.Net;

string myIP,myMac;

System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;

if ( addressList.Length>1)

{

myIP = addressList[0].ToString();

myMac = addressList[1].ToString();

}

else

{

myIP = addressList[0].ToString();

myMac = "没有可用的连接";

}

myIP地址就是服务器端的ip地址。

获取客户端的ip地址,可以使用

//获取登录者ip地址

string ip = Request.ServerVariables["REMOTE_ADDR"].ToString();

2、通过JS获取

<html>

<head>

<title></title>

<meta http-equiv="Content-Type" content="text/html; charset=gbk">

</head>

<body>

<object classid="CLSID:76A64158-CB41-11D1-8B02-00600806D9B6" id="locator" style="display:none;visibility:hidden"></object>

<object classid="CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223" id="foo" style="display:none;visibility:hidden"></object>                                                        

<form name="myForm">

<br/>MAC地址:<input type="text" name="macAddress">

<br/>IP地址:<input type="text" name="ipAddress">

<br/>主机名:<input type="text" name="hostName">

</form>

</body>

</html>

<script language="javascript">

var sMacAddr="";

var sIPAddr="";

var sDNSName="";

var service = locator.ConnectServer();

service.Security_.ImpersonationLevel=3;

service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');

</script>

<script FOR="foo" EVENT="OnObjectReady(objObject,objAsyncContext)" LANGUAGE="JScript">

        if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true){

                          if(objObject.IPEnabled && objObject.IPAddress(0) !=null && objObject.IPAddress(0) != "undefined")

                                        sIPAddr = objObject.IPAddress(0);

                          if(objObject.MACAddress != null &&objObject.MACAddress != "undefined")

                    sMacAddr = objObject.MACAddress;

                          if(objObject.DNSHostName != null &&objObject.DNSHostName != "undefined")

                                        sDNSName = objObject.DNSHostName;

         }

</script>

<script FOR="foo" EVENT="OnCompleted(hResult,pErrorObject, pAsyncContext)" LANGUAGE="JScript">

       myForm.macAddress.value=sMacAddr;

myForm.ipAddress.value=sIPAddr;

       myForm.hostName.value=sDNSName;

</script>
