asp.net中获取当前url的方法
HttpContext.Current.Request.Url.ToString() 并不可靠。
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()獲取到的卻是
http://localhost/search.aspxuser=http://csharp.xdowns.com&tag=¼¼Êõ
正確的方法是：HttpContext.Current.Request.Url.PathAndQuery1、通過ASP.NET獲取
如果測試的url地址是http://www.test.com/testweb/default.aspx, 結果如下：
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、通過JS獲取
<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>

獲取IP
1、ASP.NET中獲取
獲取服務器的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 = "沒有可用的連接"；
}
myIP地址就是服務器端的ip地址。
獲取客戶端的ip地址，可以使用
//獲取登錄者ip地址
string ip = Request.ServerVariables["REMOTE_ADDR"].ToString();
2、通過JS獲取
<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/>主機名：<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>
