Uncaught exception 'Google_Auth_Exception' with message 'Invalid code'

问题

i'm tring to migrate my google calendar access from Zend to new google API since they closed the service in november. My web app uses google api to create some events.

I'm facing a recurring message that i could not resolve : Uncaught exception 'Google_Auth_Exception' with message 'Invalid code'

Here's my code :

define('STDIN',fopen("php://stdin","r"));
require_once '../../utils/google-api-php-client-master/autoload.php';

    /**********************
    OAUTH 2.0 AUTHORIZATION
    ***********************/


    $client = new Google_Client();

    // OAuth2 client ID and secret can be found in the Google Developers Console.
    $client->setClientId('XXXXXX);
    $client->setClientSecret('XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX');
    $client->setRedirectUri('XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX');
    $client->addScope('https://www.googleapis.com/auth/calendar');

    $service = new Google_Service_Calendar($client);

    $authUrl = $client->createAuthUrl();


    //Request authorization
    print "Please visit:\n$authUrl\n\n";
    print "Please enter the auth code:";
    echo(trim(fgets(STDIN)));
    $authCode = trim(fgets(STDIN));

    // Exchange authorization code for access token
    $accessToken = $client->authenticate($authCode);
    $client->setAccessToken($accessToken);

Could someone please help me ?

I finally got this stuff to start working myself and a lot of searching. I was also using Zend before. There is a very good website at Daimto.com where you can see a bunch of tutorials. Here is the code that worked for me to add an event using the code form Daimto.com and adding code for adding an event in the body. Remember you need ot have the service email added to the share of your google calendar too!

<?php
session_start();        
require_once './google-api-php-client/src/Google/Client.php';
require_once './google-api-php-client/src/Google/Service/Calendar.php';     

$client_id = '6846057_YOUR_CLIENT_ID_HERE_pg3q8r6.apps.googleusercontent.com';
$Email_address = '68460_YOUR_SERVICE_EMAIL_HERE_developer.gserviceaccount.com';  
$key_file_location = '_KEY_FILE_LOCATION_HERE_8.p12';       
$client = new Google_Client();      
$client->setApplicationName("_APP_NAME_HERE_");
$key = file_get_contents($key_file_location);    
// seproate additional scopes with a comma   
$scopes ="https://www.googleapis.com/auth/calendar";    
$cred = new Google_Auth_AssertionCredentials(    
   $Email_address,       
    array($scopes),     
    $key         
    );      
$client->setAssertionCredentials($cred);
if($client->getAuth()->isAccessTokenExpired()) {        
    $client->getAuth()->refreshTokenWithAssertion($cred);       
}       
$service = new Google_Service_Calendar($client);    

?>

<html><body>

<?php
    //$service = new Google_Service_Calendar($client);
    //
    $event = new Google_Service_Calendar_Event();
    $event->setSummary('Event 2');
    $event->setLocation('Somewhere');
    $start = new Google_Service_Calendar_EventDateTime();
    $start->setDateTime('2015-06-22T19:00:00.000+01:00');
    $start->setTimeZone('Europe/London');
    $event->setStart($start);
    $end = new Google_Service_Calendar_EventDateTime();
    $end->setDateTime('2015-06-22T19:25:00.000+01:00');
    $end->setTimeZone('Europe/London');
    $event->setEnd($end);
    //
     $calendar_id = "nm_GOOGLE_CAL_ID_HERE_@group.calendar.google.com";
    //
    $new_event = null;
    //
    try {
        $new_event = $service->events->insert($calendar_id, $event);
        //
        $new_event_id= $new_event->getId();
    } catch (Google_ServiceException $e) {
        syslog(LOG_ERR, $e->getMessage());
    }
    //
    $event = $service->events->get($calendar_id, $new_event->getId());
    //
    if ($event != null) {
        echo "Inserted:";
        echo "EventID=".$event->getId();
        echo "Summary=".$event->getSummary();
        echo "Status=".$event->getStatus();
    }    

?>
