php - Google 日历 API - 创建事件时不会向与会者发送邀请电子邮件

Question

我想使用 google api 将事件添加到 google 日历。
但事件创建后，邀请电子邮件不会发送到与会者电子邮件列表。
这是我的代码:

 <?php
    require_once '../../src/Google_Client.php';
    require_once '../../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('309388785502.apps.googleusercontent.com');
     $client->setClientSecret('hvJQUDYz4rY0HiYcgS46yxB-');
     $client->setRedirectUri('http://localhost/GoogleApi/google-api-php-client/examples/calendar/simple.php');
     $client->setDeveloperKey('AIzaSyAbBRxRKM9mkXKA17Bruul6lCq-vhR6gqc');
    $cal = new Google_CalendarService($client);
    if (isset($_GET['logout'])) {
      unset($_SESSION['token']);
    }

    if (isset($_GET['code'])) {
      $client->authenticate($_GET['code']);
      $_SESSION['token'] = $client->getAccessToken();
      header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']);
    }

    if (isset($_SESSION['token'])) {
      $client->setAccessToken($_SESSION['token']);
    }

    if ($client->getAccessToken()) {

     $event = new Google_Event();
      $event->setSummary('Halloween3');
      $event->setLocation('The Neighbourhood');
      $start = new Google_EventDateTime();
      $start->setDate('2013-10-3');
      $event->setStart($start);
      $end = new Google_EventDateTime();
      $end->setDate('2013-10-3');
      $event->setEnd($end);
      $event->sendNotifications=true;
      $event->maxAttendees=2;
      $attendee1 = new Google_EventAttendee();
      $attendee2 = new Google_EventAttendee();
    $attendee1->setEmail("cuong***.ictu@gmail.com");
    $attendee2->setEmail("webtr***@gmail.com");
    $attendees = array($attendee1,$attendee2);
    $event->attendees = $attendees;

      $createdEvent = $cal->events->insert('primary', $event);

    $_SESSION['token'] = $client->getAccessToken();
    } else {
      $authUrl = $client->createAuthUrl();
      print "<a class='login' href='$authUrl'>Connect Me!</a>";
    }

?>

所以我的问题是如何在从 API 创建事件后向与会者列表发送电子邮件？
谢谢你。

Answer 1

insert 方法有一个可选参数:

    /**
 * Creates an event. (events.insert)
 *
 * @param string $calendarId Calendar identifier.
 * @param Google_Event $postBody
 * @param array $optParams Optional parameters.
 *
 * @opt_param int maxAttendees The maximum number of attendees to include in the response. If there are more than the specified number of attendees, only the participant is returned. Optional.
 * @opt_param bool sendNotifications Whether to send notifications about the creation of the new event. Optional. The default is False.
 * @return Google_Event
 */

所以我是这样解决的:

[... ]$event->attendees = $attendees;

$optionaArguments = array("sendNotifications"=>true);
$createdEvent = $cal->events->insert($idCalendario, $event, $optionaArguments);
[...]

现在，与会者会收到一封带有 .ics 文件的电子邮件，就像来自 Google 日历的普通邀请一样
