使用curl登录WS1

问题描述：

I'm trying to login into ws1.com using curl, however whenever i put the POST to true I'm getting error: Bad Request, this is the code that i tried:

<?php
$LOGINURL = "https://secure2.ws1.com/login";
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax)";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$LOGINURL);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "_csrf=QTRvNkJKaUoWBFYDBHkLDHFkP0MdMhAPOUZCASR9Xh4ZRDx7BC8LGA%3D%3D&LoginForm%5Bemail%5D=naczzalid%40hotmail.com&LoginForm%5Bpassword%5D=csc1233&LoginForm%5BrememberMe%5D=0&login-button=");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt");
echo $result = curl_exec ($ch);
curl_close ($ch);
?>

Anyone please can explain to me what is the problem in this so i can learn how to do it?

I tested some things with this form and if the csrf code is incorrect, then it gives a bad request.

The csrf value changes for every request and is tied to your cookies. So you need to fetch the login page first and extract the correct csrf code before submitting.

Working code:

<?php
$LOGINURL = "https://secure2.ws1.com/login";
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax)";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$LOGINURL);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt");
$result = curl_exec ($ch);

// extract csrf token
preg_match('/<input type="hidden" name="_csrf" value="([^"]+)">/i', $result, $csrf);
$csrf = $csrf[1];
$csrf = urlencode($csrf);

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "_csrf={$csrf}&LoginForm%5Bemail%5D=naczzalid%40hotmail.com&LoginForm%5Bpassword%5D=csc1233&LoginForm%5BrememberMe%5D=0&login-button=");

$result = curl_exec($ch);

curl_close ($ch);

var_dump($result);
