PHP获取Cookie实现模拟登录代码

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);
