本文主要和大家分享PHP获取Cookie实现模拟登录代码，希望能帮助到大家。
一、定义Cookie存储路径
必须使用绝对路径
$cookie_jar = dirname(__FILE__)."/pic.cookie";
二、获取Cookie
将cookie存入文件
$url = "http://1.2.3.4/";$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar);$content = curl_exec($ch); curl_close($ch);
三、模拟浏览器获取验证码
该服务器验证码有漏洞，可以自己指定
取出cookie，一起提交给服务器，让服务器以为是浏览器打开登陆页面
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://1.2.3.4/getCheckpic.action?rand=6836.185874812305'); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_jar); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);$ret = curl_exec($ch); curl_close($ch);
四、POST提交
$post = "name=2&userType=1&passwd=asdf&loginType=1&rand=6836&imageField.x=25&imageField.y=7"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "http://1.2.3.4/loginstudent.action"); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_jar);$result=curl_exec($ch); curl_close($ch);
五、到指定页面获取数据
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "http://1.2.3.4/accountcardUser.action"); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER,0); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_jar);$html=curl_exec($ch);// var_dump($html);curl_close($ch);
