一、定義Cookie存儲路徑

必須使用絕對路徑

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

 

二、獲取Cookie

將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、模擬瀏覽器獲取驗證碼

該服務器驗證碼有漏洞，可以自己指定

取出cookie，一起提交給服務器，讓服務器以為是瀏覽器打開登陸頁面

$ch = curl_init();
curl_setopt($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、到指定頁面獲取數據

$ch = curl_init();
curl_setopt($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);
