请教一个关于php的问题.

[weixin_38053335]

   由于公司接了一个业务. 给一个网站作注册推广.由于对方不能提供任何东西.我只能自己写一个统计,以服务器作一个转发. 现遇到一个关于验证码的问题..  验证码地址: http://www.sss988.com/captcha/index  注册页面地址: http://www.sss988.com/zh-cn/home/register 我这边现在是直接打开难码页面没任何输出.而在注册页面可以正常显示验证码. 从注册页面再打开的单独难码页面也可以正常显示.但一旦新开一个窗口或选项卡. 就不输出任何内容.. 之前是正常的.我用php后台给作了个转接. 用fsockopen 打开这个地址获取内容及cookie,发给浏览器.之前都好好的. 最近我发送请求一直返回302..很郁闷.. 我这边的验证码页面: v.php <?php include_once('common.inc.php'); if(function_exists('date_default_timezone_set')) date_default_timezone_set('Etc/GMT-8'); $_cookies = array(); $_cookies['affcode'] = '220143'; $header = get_HeaderInfo('www.sss988.com','GET','/captcha/index',array(),$_cookies); $data = get_SendData('www.sss988.com',80,$header); header("Content-type: image/gif"); echo $data['data']; common.inc.php 内容 <?php if(!function_exists('fsockopen')){ function _fsockopen($host, $port, &$errno, &$errstr, $timeout){ $ip = @gethostbyname($host); $s = @socket_create(AF_INET, SOCK_STREAM, 0); if(socket_set_nonblock($s)){ $r = @socket_connect($s, $ip, $port); if ($r || socket_last_error() == EINPROGRESS) { $errno = EINPROGRESS; return $s; } } $errno = socket_last_error($s); $errstr = socket_strerror($errno); socket_close($s); return false; } } function get_ip(){ isset($_SERVER['HTTP_X_FORWARDED_FOR']) or $_SERVER['HTTP_X_FORWARDED_FOR'] = ''; isset($_SERVER['REMOTE_ADDR']) or $_SERVER['REMOTE_ADDR'] = ''; isset($_SERVER['HTTP_CLIENT_IP']) or $_SERVER['HTTP_CLIENT_IP'] = ''; if($_SERVER['HTTP_X_FORWARDED_FOR'] && $_SERVER['REMOTE_ADDR']) { $ip = $_SERVER['HTTP_X_FORWARDED_FOR']; if(strpos($ip, ',') !== false) { $tmp = explode(',', $ip); $ip = trim(end($tmp)); } if(is_ip($ip)) return $ip; } if(is_ip($_SERVER['HTTP_CLIENT_IP'])) return $_SERVER['HTTP_CLIENT_IP']; if(is_ip($_SERVER['REMOTE_ADDR'])) return $_SERVER['REMOTE_ADDR']; return 'unknown'; } function is_ip($ip) { return preg_match("/^([0-9]{1,3}\.){3}[0-9]{1,3}$/", $ip); } function get_HeaderInfo($host,$type='GET',$file='/',$params=array(),$cookies=array()){ $_params = $_cookies = ''; foreach($params as $key=>$value){ $_params .= "&".$key."=".urlencode($value); } $_params = (strlen($_params) > 1) ? substr($_params,1) : ''; foreach($cookies as $key=>$value){ $_cookies .= "; ".$key."=".urlencode($value); } $_cookies = (strlen($_cookies) > 2) ? substr($_cookies,2) : ''; $file .= ($type == 'GET') ?
