因此，在研究了几个小时之后，我找不到一个解决方案。我试图使用Google日历API的v3在我的主日历上创建一个事件，但我没有体验到预期的行为。
在这个例子中我使用了服务器到服务器的身份验证，为此我创建了服务帐户凭证，将密钥对移动到测试脚本所在的目录中，并在开发者控制台中将Google Calendar API设置为"On"。
在下面你会发现有争议的代码。
预期结果（如Google所述）是在成功创建事件/将事件添加到日历时，Event对象或数组（根据您的要求）。在这两种情况下，我都收到了Event对象或数组，但事件没有显示在日历中。如果我尝试访问创建的事件数据集附带的"htmlLink"，我收到一条错误消息，显示"此事件不存在"。
我可以想象，既然我得到了一个Event对象，它包含了所有必要的细节，那么它就是成功的;但没有雪茄。我试着玩弄事件的"可见性"属性（将其设置为"公共"），但仍然没有运气。
如果有人能在这里帮我一把，我将不胜感激。

require_once __DIR__ . '/GoogleAPI/Google_Client.php';

$google = new Google_Client();

$google->setUseObjects(TRUE);
$google->setClientId(%my_client_id%);
$google->setAssertionCredentials(

        ),
        file_get_contents(__DIR__ . '/google_key.p12')
    )
);

$service = new Google_CalendarService($google);

$event = new Google_Event();

$event->setSummary('Test Appointment');
$event->setLocation('Testing');
$event->setVisibility('public');

$start = new Google_EventDateTime();
$start->setDateTime('2014-03-28T10:00:00.000-05:00');
$event->setStart($start);

$end = new Google_EventDateTime();
$end->setDateTime('2014-03-28T10:30:00.000-05:00');
$event->setEnd($end);

$createdEvent = $service->events->insert('primary', $event, array('maxAttendees' => 1, 'sendNotifications' => FALSE));

var_dump($createdEvent);
