asp.net获取URL和IP地址的方法汇总
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
<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>
