使用Google日曆檢索事件時未顯示任何事件

Question

當我試圖檢索Google日曆上的事件時，我遇到了我的代碼問題。下面是我的代碼：

<?php 

require_once 'google-api-php-client/src/Google_Client.php'; 
require_once 'google-api-php-client/src/contrib/Google_CalendarService.php'; 

session_start(); 

$client = new Google_Client(); 
$client->setApplicationName("Google Calendar PHP Starter Application"); 

// Visit https://code.google.com/apis/console?api=calendar to generate your 
// client id, client secret, and to register your redirect uri. 
$client->setClientId('client id'); 
$client->setClientSecret('client secret'); 
$client->setRedirectUri('redirect uri'); 
$client->setDeveloperKey('developer key'); 

$cal = new Google_CalendarService($client); 

$events = $cal->events->listEvents('email address for google calendar'); 

echo $events;  
?> 

當我打印出我的谷歌日曆的事件，我得到的是一個空的數組。不過，我確信我的谷歌日曆中有幾個事件。

其實，我的事件嘗試用下面的代碼添加事件：

$event = new Google_Event(); 
$event->setSummary('Appointment'); 
$event->setLocation('Somewhere'); 
$start = new Google_EventDateTime(); 
$start->setDateTime('2013-08-23T10:00:00.000-07:00'); 
$event->setStart($start); 
$end = new Google_EventDateTime(); 
$end->setDateTime('2013-08-23T10:25:00.000-07:00'); 
$event->setEnd($end); 

echo $events; 

$createdEvent = $cal->events->insert('email address for google calendar', $event); 

然而，當我做這個代碼我最終收到一個錯誤，指出：

Fatal error: Uncaught exception 'Google_ServiceException' with message 'Error calling POST https://www.googleapis.com/calendar/v3/calendars/ 'email address for google calendar'/events?key='key'......................................lib/google-api-php-client/src/io/Google_REST.php on line 66

有人可以幫助我嗎？

因爲它是一個數組，你需要使用print_r而不是echo。嘗試更換：

echo $events; 

與

print"<pre>".print_r($events, true)."</pre>";
