php – Google Calendar API出错 – 401添加日历活动时需要登录

包含的代码是重定向发生时发生的情况：

session_start();

require(APPPATH . 'libraries/google/apiClient.php');
require(APPPATH . 'libraries/google/contrib/apiCalendarService.php');

$apiClient = new apiClient();
$apiClient->setUSEObjects(true);
$calendarService = new apiCalendarService($apiClient);

if(isset($_SESSION['oauth_access_token'])) 
{
    $apiClient->setAccessToken($_SESSION['oauth_access_token']);
} 
else 
{
    $token = $apiClient->authenticate();
    $_SESSION['oauth_access_token'] = $token;
}

在进行身份验证后,我会使用我的URL中的选项重定向回我的localhost站点：

http://localhost/project/acp/sync/auth/?code=4/DS91JtSJ5_9Q-Z55Kpyh2AicyWdL

我的脚本将通过使用auth和代码查询字符串检查URI段来检测何时进行了身份验证 – 因此我可以开始将事件导入我的Google日历帐户,直到我抛出此错误：

Fatal error: Uncaught exception 'apiServiceException' with message 'Error calling POST https://www.googleapis.com/calendar/v3/calendars/primary/events?key={removed API key}: (401) Login Required' in /Users/Me/Sites/project/application/libraries/google/io/apiREST.php:86

导入事件的代码(代码来自Google API示例)：

session_start();

require(APPPATH . 'libraries/google/apiClient.php');
require(APPPATH . 'libraries/google/contrib/apiCalendarService.php');

$apiClient = new apiClient();
$apiClient->setUSEObjects(true);
$service = new apiCalendarService($apiClient);

$event = new Event();
$event->setSummary('Appointment');
$event->setLocation('Somewhere');
$start = new EventDateTime();
$start->setDateTime('2011-06-03T10:00:00.000-07:00');
$event->setStart($start);
$end = new EventDateTime();
$end->setDateTime('2011-06-03T10:25:00.000-07:00');
$event->setEnd($end);
$attendee1 = new EventAttendee();
$attendee1->setEmail('attendeeEmail');
// ...
$attendees = array($attendee1,// ...
                  );
$event->attendees = $attendees;
$createdEvent = $service->events->insert('primary',$event);

echo $createdEvent->getId();

我试过谷歌搜索错误,但我似乎没有找到任何解决方案,你知道我怎么能解决这个问题？
