PHP获取Cookie模拟登录
作者：方倍工作室
一、定义Cookie存储路径
必须使用绝对路径
[code]$cookie_jar = dirname(__FILE__)."/pic.cookie";[/code]
二、获取Cookie
将cookie存入文件
[code]$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($ch);[/code]
三、模拟浏览器获取验证码
该服务器验证码有漏洞，可以自己指定
取出cookie，一起提交给服务器，让服务器以为是浏览器打开登陆页面
[code]$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($ch);
[/code]
四、POST提交
[code]$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($ch);
[/code]
五、到指定页面获取数据
[code]$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);[/code]
