ASP.NET以及JS获取URL和IP地址的常用方法

Posted on 2009-02-26 19:10  chen eric  阅读(998)  评论(0编辑  收藏  举报

 


asp.net中获取当前url的方法

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.PathAndQuery1、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:                       http://www.test.com/
Request.Url.LocalPath:                  /testweb/default.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
{
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>
<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">
        
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>
