获取URL:
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\testweb\
Request.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 >

 

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 );

 

thisDLoc = document.location; <BR>

thisURL = document.URL; <BR>

thisHREF = document.location.href; <BR>

thisSLoc = self.location.href;<BR>

 

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 );

 

thisTLoc = top.location.href; <BR>

thisPLoc = parent.document.location; <BR>

thisTHost = top.location.hostname; <BR>

thisHost = location.hostname;<BR>

 

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 );

<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

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

 

<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>

 

<script language="javascript">
   var sMacAddr="";
   var sIPAddr="";
   var sDNSName="";

   var service = locator.ConnectServer();
   service.Security_.ImpersonationLevel=3;
   service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');

 

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

         myForm.macAddress.value=sMacAddr;
   myForm.ipAddress.value=sIPAddr;
         myForm.hostName.value=sDNSName;
