Я экспериментировал снова и снова, но то, что я получил до сих пор, не позволяет мне войти в Pinterest с CURL, и я не могу понять почему ..

function pinLogin()
{   
    $login_post     = array(
        'source_url' => '/login/',
        'data' => '{
            "options":{
                "username_or_email":"email",
                "password":"password"
                },
            "context":{}}',
        'module_path' => 'App()>LoginPage()>Login()>Button(text=Log In, size=large, class_name=primary, type=submit)',
    );

    $httpheaders    = array(
       'Connection: keep-alive',
       'Pragma: no-cache',
       'Cache-Control: no-cache',
       'Content-Type: application/x-www-form-urlencoded; charset=UTF-8',
       'User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:35.0) Gecko/20100101 Firefox/35.0',
       'Accept: application/json, text/javascript, */*; q=0.01',
       'Accept-Language: en-US,en;q=0.5',
       'Accept-Encoding: gzip, deflate',
    );

    $login_header   = array(
        'X-Pinterest-AppState: active',
        'X-NEW-APP: 1',
        'X-APP-VERSION: 71854ca',
        'X-Requested-With: XMLHttpRequest',
        'Accept: application/json, text/javascript, */*; q=0.01'
    );

    // request home page to establish cookies and a session, set curl options
        $ch = curl_init('http://www.pinterest.com/');
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
        curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
        curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
        curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
        curl_setopt($ch, CURLOPT_VERBOSE, 1);
        curl_setopt($ch, CURLOPT_STDERR, fopen('/tmp/debug.txt', 'w+'));
        curl_setopt($ch, CURLOPT_HEADER, 1);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $httpheaders);

        $data = curl_exec($ch);
    // ----------------------------------------------------------------------------

    // parse the csrf token out of the cookies to set later when logging in
        list($headers, $body) = explode("\r\n\r\n", $data, 2);

        preg_match('/csrftoken=(.*?)[\b;\s]/i', $headers, $csrf_token);

        // next request the login page
        curl_setopt($ch, CURLOPT_URL, 'http://www.pinterest.com/login/');
        $data = curl_exec($ch);
    // ----------------------------------------------------------------------------

    // perform login post    
        $login_header[] = 'X-CSRFToken: ' . $csrf_token[1];

        curl_setopt($ch, CURLOPT_URL, 'http://www.pinterest.com/resource/UserSessionResource/create/');
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $login_post);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array_merge($httpheaders, $login_header));
        curl_setopt($ch, CURLOPT_REFERER, 'http://www.pinterest.com/login/');
        curl_setopt($ch, CURLOPT_HEADER, 0);

        $data = curl_exec($ch);
    // ----------------------------------------------------------------------------


    if (curl_getinfo($ch, CURLINFO_HTTP_CODE) != 200)
    {
        echo "Error logging in.<br />";
        var_dump(curl_getinfo($ch));

    } else {
        $response = json_decode($data, true);

        if ($response === null)
        {
            echo "Failed to decode JSON response.<br /><br />";
            var_dump($response);
        } else if ($response['resource_response']['error'] === null) {
            echo "Logged in..";
        }
        print_r($response);
    }
}

Я пытался эмулировать те же заголовки, которые отправляются в pinterest, но я по-прежнему не могу войти по какой-то причине ..
