Login to Google with PHP and Curl, Cookie turned off?

Question

I have this code for logging into Google using Simple DOM Parser with curl. I've tried adding in the cookiejar file, but to no avail. I keep getting the message:

Your browser's cookie functionality is turned off. Please turn it on.

Any idea on how to solve this?

Here's my code for reference:

$html = file_get_html('https://accounts.google.com/ServiceLogin?hl=en&service=alerts&continue=http://www.google.com/alerts/manage');

//... some code for getting post data here

$curl_connection = curl_init('https://accounts.google.com/ServiceLoginAuth');
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl_connection, CURLOPT_COOKIEJAR, COOKIEJAR);
curl_setopt($curl_connection, CURLOPT_COOKIEFILE, COOKIEJAR);
curl_setopt($curl_connection, CURLOPT_HEADER, true);  
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 120);
curl_setopt($curl_connection, CURLOPT_TIMEOUT, 120);
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);

$result = curl_exec($curl_connection);
curl_close($curl_connection);

echo $result;

Here is some modified code that works.

It first requests the login page to get the initial cookies and extract the required values for the login form. Next it performs a post to the login service. It then checks to see if it is trying to use javascript and meta tags to redirect to the destination URL.

It seemed like you already have code for grabbing the form fields, so I didn't post mine, but if you need it let me know. Just make sure $formFields is an associative array with keys being the field name, and the value being the field value.

<?php

/**
 * Log in to Google account and go to account page
 *
 */

$USERNAME = '[email protected]';
$PASSWORD = 'password';
$COOKIEFILE = 'cookies.txt';

// initialize curl handle used for all requests
$ch = curl_init();

// set some options on the handle
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, $COOKIEFILE);
curl_setopt($ch, CURLOPT_COOKIEFILE, $COOKIEFILE);
curl_setopt($ch, CURLOPT_HEADER, 0);  
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);

// url of our first request fetches the account login page
curl_setopt($ch, CURLOPT_URL, 
  'https://accounts.google.com/ServiceLogin?hl=en&service=alerts&continue=http://www.google.com/alerts/manage');
$data = curl_exec($ch);

// extract form fields from account login page
$formFields = getFormFields($data);

// inject email and password into form
$formFields['Email']  = $USERNAME;
$formFields['Passwd'] = $PASSWORD;
unset($formFields['PersistentCookie']);

$post_string = http_build_query($formFields); // build urlencoded POST string for login

// set url to login page as a POST request
curl_setopt($ch, CURLOPT_URL, 'https://accounts.google.com/ServiceLoginAuth');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);

// execute login request
$result = curl_exec($ch);

// check for "Redirecting" message in title to indicate success
// based on your language - you may need to change this to match some other string
if (strpos($result, '<title>Redirecting') === false) {
    die("Login failed");
    var_dump($result);
}

// login likely succeeded - request account page; unset POST so we do a regular GET
curl_setopt($ch, CURLOPT_URL, 'https://myaccount.google.com/?utm_source=OGB');
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, null);

// execute request for login page using our cookies
$result = curl_exec($ch);

echo $result;


// helpef functions below

// find google "#gaia_loginform" for logging in
function getFormFields($data)
{
    if (preg_match('/(<form.*?id=.?gaia_loginform.*?<\/form>)/is', $data, $matches)) {
        $inputs = getInputs($matches[1]);

        return $inputs;
    } else {
        die('didnt find login form');
    }
}

// extract all <input fields from a form
function getInputs($form)
{
    $inputs = array();

    $elements = preg_match_all('/(<input[^>]+>)/is', $form, $matches);

    if ($elements > 0) {
        for($i = 0; $i < $elements; $i++) {
            $el = preg_replace('/\s{2,}/', ' ', $matches[1][$i]);

            if (preg_match('/name=(?:["\'])?([^"\'\s]*)/i', $el, $name)) {
                $name  = $name[1];
                $value = '';

                if (preg_match('/value=(?:["\'])?([^"\'\s]*)/i', $el, $value)) {
                    $value = $value[1];
                }

                $inputs[$name] = $value;
            }
        }
    }

    return $inputs;
}
