服务端:
//
方法一
HttpContext.Current.Request.UserHostAddress;
// 方法二
HttpContext.Current.Request.ServerVariables[ " REMOTE_ADDR " ];
// 方法三
string strHostName = System.Net.Dns.GetHostName();
string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue( 0 ).ToString();
// 方法四(无视代理)
HttpContext.Current.Request.ServerVariables[ " HTTP_X_FORWARDED_FOR " ];
HttpContext.Current.Request.UserHostAddress;
// 方法二
HttpContext.Current.Request.ServerVariables[ " REMOTE_ADDR " ];
// 方法三
string strHostName = System.Net.Dns.GetHostName();
string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue( 0 ).ToString();
// 方法四(无视代理)
HttpContext.Current.Request.ServerVariables[ " HTTP_X_FORWARDED_FOR " ];
客户端:
//
方法五
var ip = ' <!--#echo var="REMOTE_ADDR"--> ' ;
alert( " Your IP address is " + ip);
// 方法六(无视代理)
function GetLocalIPAddress()
{
var obj = null;
var rslt = "";
try
{
obj = new ActiveXObject("rcbdyctl.Setting");
rslt = obj.GetIPAddress;
obj = null;
}
catch(e)
{
//
}
return rslt;
}
var ip = ' <!--#echo var="REMOTE_ADDR"--> ' ;
alert( " Your IP address is " + ip);
// 方法六(无视代理)
function GetLocalIPAddress()
{
var obj = null;
var rslt = "";
try
{
obj = new ActiveXObject("rcbdyctl.Setting");
rslt = obj.GetIPAddress;
obj = null;
}
catch(e)
{
//
}
return rslt;
}
来自印度的MCT Maulik Patel提供了一种服务端的解决方案,很好:
if
(Context.Request.ServerVariables[
"
HTTP_VIA
"
]
!=
null
)
//
using proxy
{
ip=Context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString(); // Return real client IP.
}
else // not using proxy or can't get the Client IP
{
ip=Context.Request.ServerVariables["REMOTE_ADDR"].ToString(); //While it can't get the Client IP, it will return proxy IP.
}
{
ip=Context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString(); // Return real client IP.
}
else // not using proxy or can't get the Client IP
{
ip=Context.Request.ServerVariables["REMOTE_ADDR"].ToString(); //While it can't get the Client IP, it will return proxy IP.
}
