PHP獲取Cookie模擬登錄

一、定義Cookie存儲路徑

必須使用絕對路徑

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

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

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

二、獲取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&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);
