Bad request because of the modal window

[Meurch]

So I already made a complete authorization on my site using Google auth.

But I need now to add a modal window with a "Terms of usage". So I made it the next way:

 after the clicking on the agree button, we are going to the script:

    $params = array(

        'client_id'     => '10531502378-2m6vwefwefg6g5hcjnkaaff65eo0kaop1v5.apps.googleusercontent.com',

        'client_secret' => '6AQdBsdfefwghu263-TkR',

        'redirect_uri'  => 'https://mysite.ru/_scripts/login_google.php',

        'grant_type'    => 'authorization_code',

        'code'          => $_GET['code']

    );  

    $code_to_auth = $_GET['code'];

    print_r($code_to_auth);

   

    $ch = curl_init('https://accounts.google.com/o/oauth2/token');

    curl_setopt($ch, CURLOPT_POST, 1);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $params);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_HEADER, false);

    $data = curl_exec($ch);

    curl_close($ch);    

 

    $data = json_decode($data, true);

    print_r($data);

I got an error , but the same code is working well for the login without the modal window. Maybe there are some parameters I forgot about? So I already choose my google account and I just used

document.location.href

 to define get parameters for the ajax which is going to the php script mentioned above.

[error] => invalid_grant [error_description] => Bad Request

I changed client id, secret and site domain, in my code these parameters are correct.

Hello,

Thanks for reaching out. I understand that you are receiving an invalid_grant error. This error can usually be resolved by regenerating the refresh token. Can you please try this, and if you are still receiving the invalid_grant error, reply to us privately with the complete request and response?

Thanks,

Can you say more about the refresh token? So firstly I should do this to choose my account:

$params = array(

    'client_id'     => '105310604278sdfkaop1v5.apps.googleusercontent.com',

    'redirect_uri'  => 'https://sdf.ru/_scripts/login_google.php',

    'response_type' => 'code',

    'scope'         => 'https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile',

    'state'         => '123'

     );

                                     

 $url = 'https://accounts.google.com/o/oauth2/auth?' . urldecode(http_build_query($params));

After that, as I understand maybe incorrectly, I need only the $auth_code to get the $data:

$params = array(

        'client_id'     => '105310604kaaff65eo0kaop1v5.apps.googleusercontent.com',

        'client_secret' => '6AQdrSjG2u263-TkR',

        'redirect_uri'  => 'https://sdf.ru/_scripts/login_google.php',

        'grant_type'    => 'authorization_code',

        'code'          => $auth_code

    );  

   

    $ch = curl_init('https://accounts.google.com/o/oauth2/token');

    curl_setopt($ch, CURLOPT_POST, 1);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $params);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_HEADER, false);

    $data = curl_exec($ch);

    curl_close($ch);    

So I got an error that data is incorrect.

I saw via the debug $auth_code is the same as I got before the modal Window step.

So, maybe there are some additional parameters I forgot, or what should I check next?

Hello,

If you are using the supported PHP client library, you should use one of the authentication code samples depending on which auth flow you are using (web/desktop). You can find the authentication code samples found for each flow on the following pages:

• Desktop Authentication
• Web Authentication

You can follow the steps given to regenerate your refresh token, which should resolve the invalid_grant error. After generating the token, please copy it to your .INI file. 

Regards,
