HttpContext.Current.Request.Url.ToString()

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

1、通过ASP.NET获取
如果测试的url地址是 http: // www.test.com/testweb/defau.aspx, 结果如下：
Request.ApplicationPath:                 / testweb
Request.CurrentExecutionFilePath:        /testweb/defau .aspx
Request.FilePath:                        /testweb/defau .aspx
Request.Path:                            /testweb/defau .aspx
Request.PhysicalApplicationPath:        E:\WWW\testweb
Request.PhysicalPath:      E:\WWW\testweb\ default .aspx
Request.RawUrl:                          /testweb/defau .aspx
Request.Url.AbsolutePath:                /testweb/defau .aspx
Request.Url.AbsoluteUrl:                http: // www.test.com/testweb/defau.aspx
Request.Url.Host:                       www.test.com
Request.Url.LocalPath:                   /testweb/defau .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 )
ExpandedBlockStart.gifContractedBlock.gif dot.gif
{
     myIP = addressList [0].ToString();
     myMac = addressList [1].ToString();
    ExpandedBlockEnd.gif
}
else
ExpandedBlockStart.gifContractedBlock.gif dot.gif
{
     myIP = addressList [0].ToString();
     myMac = "没有可用的连接"；
ExpandedBlockEnd.gif
}
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 " >
ExpandedBlockStart.gifContractedBlock.gif         if (objObject.IPEnabled !=   null   && objObject.IPEnabled !=   " undefined "   && objObject.IPEnabled ==   true ) dot.gif {
                          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;
ExpandedBlockEnd.gif         }
</ script>

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

myForm.macAddress.value = sMacAddr;
myForm.ipAddress.value = sIPAddr;
myForm.hostName.value = sDNSName;
</ script>
