导入Google联系人时的OAuth问题

Good Morning - I am using the following YouTube tutorial Tutoriel PHP - Importer des contacts Google to try and import Google contacts.

When I click on the link to import Google contacts, instead of asking for permission and getting the contacts and displaying them on screen, I get the following errors:

Warning: Missing argument 1 for Google_Client::authenticate(), called in /var/www/html/restaurant_test/index.php on line 34 and defined in /var/www/html/restaurant_test/lib/google-api-client/Google_Client.php on line 124

Notice: Undefined variable: code in /var/www/html/restaurant_test/lib/google-api-client/Google_Client.php on line 127

Fatal error: Uncaught exception 'Google_Auth_Exception' with message 'Invalid code' in /var/www/html/restaurant_test/lib/google-api-client/Auth/OAuth2.php:88 Stack trace: #0 /var/www/html/restaurant_test/lib/google-api-client/Google_Client.php(127): Google_Auth_OAuth2->authenticate(NULL, false) #1 /var/www/html/restaurant_test/index.php(34): Google_Client->authenticate() #2 {main} thrown in /var/www/html/restaurant_test/lib/google-api-client/Auth/OAuth2.php on line 88

Please tell me what to do in order to fix the errors. Thank you.

Here is my code:

<?php 
error_reporting(E_ALL);
ini_set("display_errors", 1);

session_start(); ?>

<head>

}

{
    $url = $client->createAuthUrl();

        curl_close($curl);

            'phone' => isset($contact['gd$phoneNumber'][0]['$t']) ? $contact['gd$phoneNumber'][0]['$t'] :false,
            );
        }
        var_dump($return);
    }

Looks like you're forgetting to pass the code to the authenticate method. Here's the documentation and implementation of the authenticate method in Google_Client.php:

/**
 * Attempt to exchange a code for an valid authentication token.
 * If $crossClient is set to true, the request body will not include
 * the request_uri argument
 * Helper wrapped around the OAuth 2.0 implementation.
 *
 * @param $code string code from accounts.google.com
 * @param $crossClient boolean, whether this is a cross-client authentication
 * @return string token
 */
public function authenticate($code, $crossClient = false)
{
  $this->authenticated = true;
  return $this->getAuth()->authenticate($code, $crossClient);
}

So changing your code as below will most likely resolve the issue:

if (isset($_GET['code'])) {
    $client->authenticate($_GET['code']); // <-- Add code parameter here
    $_SESSION['token'] = $client->getAccessToken();
    header('Location: ' . $redirect_uri);
}
