这次给大家带来php curl带有csrf-token验证模拟提交实例详解,php curl带有csrf-token验证模拟提交的注意事项有哪些,下面就是实战案例,一起来看一下。

1.通过正则获取token
2.带上获取到的token模拟提交

下面是一个成功的例子

目录结构

│ form.php –需要模拟的表单 │ getForm.php – 模拟提交程序 │ post.php –表单验证程序 │ └─cookie – cookie存放目录

getForm.php

<?php $cookie_file = './cookie/'.time().'.cookie'; $str = getResponse(':81/form.php',[],$cookie_file); setcookie("PHPSESSID", "vc0heoa6lfsi3gger54pkns152"); preg_match('/<input name="token" type="hidden" value="(.*)"/U', $str, $match); $post['token'] = $match[1]; $post['name'] = '3333333'; $post['password'] = '12121213'; print_r(getResponse(':81/post.php', $post, $cookie_file)); function getResponse($url, $data=[], $cookie_file='', $timeout = 3) { if(empty($cookie_file)) { $cookie_file = '.cookie'; } $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_REFERER, "https://www.baidu.com"); //构造来路 curl_setopt($ch, CURLOPT_USERAGENT,"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.59 Safari/537.36"); if(!empty($data)) { curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); } curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);// 取cookie的参数是 curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie_file); //发送cookie curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); try { $handles = curl_exec($ch); curl_close($ch); return $handles; } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } unlink($cookie_file); }

form.php

<?php session_start(); $_SESSION['token'] = md5($_SERVER['REQUEST_TIME']); $_SESSION['time'] = date("Y-m-d H:i:s"); session_write_close(); //echo $_SESSION['auth']; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ""> <html xmlns=""> <head> <title> new document </title> <meta name="generator" content="editplus" /> <meta name="author" content="" /> <meta name="keywords" content="" /> <meta name="description" content="" /> </head> <body> <form action="post.php" method="post"> <p><input name="name" type="text"></p> <p><input name="password" type="password"></p> <p><input name="token" type="hidden" value="<?php echo $_SESSION['token']?>"></p> <p><input type="submit"></p> </form> </body> </html>

post.php

<?php session_start(); if(empty($_POST['token'])) { exit ("token is empty!"); } if(empty($_SESSION['token'])) { exit ("session is empty"); } if($_POST['token'] != $_SESSION['token']) { exit ("token "); } else { unset($_SESSION['token']); } echo PHP_EOL; echo "pass"; print_r($_REQUEST); echo PHP_EOL; print_r($_SERVER);
