HttpContext.Current.Request.Url.ToString() 並不可靠。

如果當前URL為
http://localhost/search.aspx?user=http://csharp.xdowns.com&tag=%BC%BC%CA%F5

通過HttpContext.Current.Request.Url.ToString()擷取到的卻是

http://localhost/search.aspxuser=http://csharp.xdowns.com&tag=¼¼Êõ

正確的方法是：

複製代碼 代碼如下:HttpContext.Current.Request.Url.PathAndQuery

1、通過ASP.NET擷取
如果測試的url地址是http://www.test.com/testweb/default.aspx, 結果如下：複製代碼 代碼如下: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、通過JS擷取 複製代碼 代碼如下:<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>

擷取IP
1、ASP.NET中擷取

擷取伺服器的IP地址：

複製代碼 代碼如下: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 = "沒有可用的串連"；
}

myIP地址就是伺服器端的ip地址。

擷取用戶端的ip地址，可以使用

複製代碼 代碼如下://擷取登入者ip地址
string ip = Request.ServerVariables["REMOTE_ADDR"].ToString();

2、通過JS擷取複製代碼 代碼如下:<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/>主機名稱：<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>
