php有几种方法伪造HTTP_REFERER页面URL来源

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;
Copy after login

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);
Copy after login

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);
Copy after login

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1.

Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
