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/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

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>

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>

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>

</head>

<body>

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

</form>

</body>

</html>

var sMacAddr="";

var sIPAddr="";

var sDNSName="";

var service = locator.ConnectServer();

service.Security_.ImpersonationLevel=3;

service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');

</script>

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>

myForm.macAddress.value=sMacAddr;

myForm.ipAddress.value=sIPAddr;

myForm.hostName.value=sDNSName;

</script>
