Uncaught exception 'Firebase\JWT\BeforeValidException' with message 'Cannot handle token prior to 2016-11-03T21:37:13+0100'

Hello I have a problem trying to use google/apiclient

Fatal error: Uncaught exception 'Firebase\JWT\BeforeValidException' with message 'Cannot handle token prior to 2016-11-03T21:37:13+0100' in C:\xampp\htdocs\Google\vendor\firebase\php-jwt\src\JWT.php:124 Stack trace: #0 C:\xampp\htdocs\Google\vendor\google\apiclient\src\Google\AccessToken\Verify.php(100): Firebase\JWT\JWT::decode('eyJhbGciOiJSUzI...', '-----BEGIN PUBL...', Array) #1 C:\xampp\htdocs\Google\vendor\google\apiclient\src\Google\Client.php(705): Google_AccessToken_Verify->verifyIdToken('eyJhbGciOiJSUzI...', '474251646530-0t...') #2 C:\xampp\htdocs\Google\app\class\google_auth.php(51): Google_Client->verifyIdToken() #3 C:\xampp\htdocs\Google\app\class\google_auth.php(35): GoogleAuth->getPayLoad() #4 C:\xampp\htdocs\Google\index.php(10): GoogleAuth->checkRedirectCode() #5 {main} thrown in C:\xampp\htdocs\Google\vendor\firebase\php-jwt\src\JWT.php on line 124

My index:

<?php
    require_once('app/ini.php');
    require_once('vendor/autoload.php');
    require_once('app/class/google_auth.php');


    $googleClient = new Google_Client();
    $auth = new GoogleAuth($googleClient);

    if ($auth->checkRedirectCode()) {
        header("Location: index.php");
    }

?>

<!DOCTYPE html>

<head>
    <title></title>

<body>

    <?php if (!$auth->isLoggedIn()): //Verificar Inicio de Sesion ?>

    <?php else: //Si no ha iniciado Sesion ?>
        Bienvenido.. <a href="logout.php">Cerrar Sesion</a>
    <?php endif; ?>

The class GoogleAuth:

<?php

                $this->client->setScopes('email');

            }
        }

The JWT library makes use of a leeway (in seconds) to account for when there is a clock skew times between the signing and verifying servers.

This error occurs when the times difference between library and your server is major than the leeway

To fix it, go to

\vendor\google\apiclient\src\Google\AccessToken\Verify.php

and increase leeway in the getJwtService function.

private function getJwtService()
  {
    $jwtClass = 'JWT';
    if (class_exists('\Firebase\JWT\JWT')) {
      $jwtClass = 'Firebase\JWT\JWT';
    }

    if (property_exists($jwtClass, 'leeway')) {
      // adds 1 second to JWT leeway
      // @see https://github.com/google/google-api-php-client/issues/827
      $jwtClass::$leeway += 10;
    }

    return new $jwtClass;
  }

You have a Server time issue. The time between your JWT Library and Server differs. That Library uses the 'UTC' timezone. Depending on your usecase, you will want to align the timezones to be in the same zone or you can comment this line if you don't need it.

// Configures the time that the token can be used (nbf claim)
// ->setNotBefore(time() + 60)

Inside this function:

public function getPayLoad(){
    $payload=$this->client->verifyIdToken()->getAttributes();
    return $payload;
}

remove getAttributes() and leave it like this:

public function getPayLoad(){
    $payload=$this->client->verifyIdToken();
    //print_r($payload); //This gives you the information you need
    return $payload;
}
