Made the CDN function code to obtain the user's real IP (PHP and Asp setting method)_PHP tutorial

asp function code:

Copy code The code is as follows:

function checkip(checkstring)' Use regular expression to determine whether the IP Legal
dim re1
set re1=new RegExp
re1.pattern=”^[0-9]{1,3}.[0-9]{1,3}.[0-9] {1,3}.[0-9]{1,3}$”
re1.global=false
re1.Ignorecase=false
checkip=re1.test(checkstring)
set re1 =nothing
end function

function get_cli_ip()'Get the real IP function, first HTTP_CLIENT_IP then HTTP_X_FORWARDED_FOR then REMOTE_ADDR
dim client_ip
if checkip(Request.ServerVariables("HTTP_CLIENT_IP"))=true then
get_cli_ip = checkip(Request .ServerVariables("HTTP_CLIENT_IP"))
else
MyArray = split(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),",")
if ubound(MyArray)>=0 then
client_ip = trim(MyArray(0))
if checkip(client_ip)=true then
get_cli_ip = client_ip
exit function
end if
end if
get_cli_ip = Request.ServerVariables(”REMOTE_ADDR ”)
end if
end function

discuz forum takes the php code of the real IP, other similar, please refer to the slight modification

(discuz modify include/common.inc.php)
Use the following code:

Copy the code The code is as follows:

if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'),'unknown')) {
$onlineip = getenv('HTTP_CLIENT_IP');
} elseif(getenv( 'HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'),

'unknown')) {

$testip = explode('.', getenv('HTTP_X_FORWARDED_FOR'));

if ($testip[0]=='192′ && $testip[1]=='168′) {
$onlineip = getenv('REMOTE_ADDR');
}
elseif( $testip[0]=='10′) {
$onlineip = getenv('REMOTE_ADDR');
}
else {
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
}

//gamesir hack end} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'),

'unknown')) {
$onlineip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($ _SERVER

['REMOTE_ADDR'],'unknown')) {
//by Johnny
$tmp_ip = explode(',',$_SERVER['HTTP_X_FORWARDED_FOR']);
$tmp_ip1 = explode (',',$tmp_ip[0]);
if ($tmp_ip1[0] =='192′ && $tmp_ip1[1] =='168′) {
$onlineip = getenv('REMOTE_ADDR ');
}else if($tmp_ip1[0]=='10′) {
$onlineip = getenv('REMOTE_ADDR');
}
else{
$onlineip = $tmp_ip[0];
}
unset($tmp_ip);unset($tmp_ip1);

}

Replace this code:

Copy code The code is as follows:

if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$onlineip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'),

'unknown')) {
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'),'unknown')) {
$onlineip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER

['REMOTE_ADDR'],'unknown')) {
$onlineip = $_SERVER['REMOTE_ADDR'];
}
