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
│ 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';
$str = getResponse('http://a.curl.com:81/form.php',[],$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('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, "https://www.baidu.com"); //构造来路

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)

unlink($cookie_file);
