php怎么伪造HTTP_REFERER页面URL来源?
php 伪造HTTP_REFERER页面URL来源的三种方法
php获取当前页面的前一个页面URL地址,即当前页面是从哪个页面链接过来的,可以使用$_SERVER['HTTP_REFERER'];
但是$_SERVER['HTTP_REFERER']也是可以被伪造欺骗的,有三种方法可以伪造和欺骗$_SERVER['HTTP_REFERER']
注:window平台 使用phpstudy集成环境 nginx 此方法失效 ,apache 正常,其他平台版未测试
第一种方法:file_get_contents
$url = "http://localhost/test/test.php"; $refer="http://www.aa.com"; $opt=array('http'=>array('header'=>"Referer: $refer")); $context=stream_context_create($opt); $file_contents = file_get_contents($url,false, $context); echo $file_contents;
file_get_contents中stream_context_create就伪造来源的重要参数了。
第二种方法:CURL
$url = "http://localhost/test/test.php"; // 请求的页面地址 $refer="http://www.aa.com"; //伪造的页面地址 $ch = curl_init(); curl_setopt ($ch, CURLOPT_URL,$url); curl_setopt ($ch, CURLOPT_REFERER,$refer); curl_exec ($ch); curl_close ($ch);
第三种方法:fsockopen
$url="http://localhost/test/test.php"; $target = "http://www.manongjc.com/"; /** sockopen 伪造 网站来源地址 * @parem $url 要访问的页面地址 * @parem $target 伪造来源页面 * @parem $port 网站端口 默认 80 * @parem 页面脚本执行时间 默认 30 s * */ function referer($url,$target,$port=80,$t=30) { $info=parse_url($url); $fp = fsockopen($info["host"], $port, $errno, $errstr, $t); if(!$fp) { echo "$errstr($errno)".PHP_EOL; } else { $out = "GET ".$info['path']." HTTP/1.1".PHP_EOL; $out .= "Host: ".$info["host"].PHP_EOL; $out .= "Referer: ".$target.PHP_EOL; $out .= "Connection: Close".PHP_EOL; $out .= PHP_EOL; fwrite($fp, $out); while(!feof($fp)) { echo fgets($fp); // 发送 head 请求头信息 } fclose($fp); } } //函数调用 referer($url,$target);

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
