通常為了安全會在表單里加入一個隨機的token值來防止csrf攻擊。

要想模擬提交有token驗證的網站其實也不難。

1.通過正則獲取token
2.帶上獲取到的token模擬提交

下面是一個成功的例子

目錄結構

│ form.php –需要模擬的表單 │ getForm.php – 模擬提交程序 │ post.php –表單驗證程序 └─cookie – cookie存放目錄

getForm.php

 ?php$cookie_file = ./cookie/ .time(). .cookie $str = getResponse( http://a.curl.com:81/form.php ,[],$cookie_file);setcookie( PHPSESSID , vc0heoa6lfsi3gger54pkns152 preg_match( / input name= token type= hidden html' target='_blank'>value= (.*) /U , $str, $match);$post[ token ] = $match[1];$post[ name ] = 3333333 $post[ password ] = 12121213 print_r(getResponse( http://a.curl.com: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, http://www.baidu.com //構造來路 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, $cookie_file);// 取cookie的參數是 curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie_file); //發送cookie curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $handles = curl_exec($ch); curl_close($ch); return $handles; catch (Exception $e) echo Caught exception: , $e- getMessage(), /n  unlink($cookie_file); }

form.php

 ?phpsession_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 http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd  html xmlns= http://www.w3.org/1999/xhtml  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
