一、定义Cookie存储路径


必须使用绝对路径

$cookie_jar = dirname(__FILE__)."/pic.cookie";


//$cookie_file = dirname(__FILE__).'/cookie.txt';

//$cookie_file = tempnam("tmp","cookie");


二、获取Cookie

$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&p_w_picpathField.x=25&p_w_picpathField.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);
