从我的网站将活动添加到我的谷歌日历

我创建了一个带有完整日历jquery插件的php页面，允许网站用户预订时间。在后台，我将事件存储到我的数据库中，然后使用谷歌日历API为我的谷歌日历创建相同的事件。

但我的实现是要求用户登录他们的谷歌帐户并在用户的日历上创建事件。如何在我（网站所有者）的谷歌日历中"无缝"创建用户事件？

我的代码如下：

<?php
session_start();
require_once __DIR__ . '/vendor/autoload.php';
define('APPLICATION_NAME', 'Google Calendar');
define('CREDENTIALS_PATH', '~/.credentials/calendar-php-quickstart.json');
define('CLIENT_SECRET_PATH', __DIR__ . '/client_secret.json');
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/calendar-php-quickstart.json
define('SCOPES', implode(' ', array(
  Google_Service_Calendar::CALENDAR)
));

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient() {
    $client = new Google_Client();
    $client->setApplicationName(APPLICATION_NAME);
    $client->setScopes(SCOPES);
    $client->setAuthConfigFile(CLIENT_SECRET_PATH);
    $client->setAccessType('offline');
    // Load previously authorized credentials from a file.
    $credentialsPath = expandHomeDirectory(CREDENTIALS_PATH);
/*if (file_exists($credentialsPath)) {
  $accessToken = file_get_contents($credentialsPath);
} else {*/
    if(!$_REQUEST['code']) {
        $authUrl = $client->createAuthUrl();
        //printf("Open the following link in your browser:n%sn", $authUrl);
        header("Location:".$authUrl);
    }
    $authCode = $_REQUEST['code'];
    $accessToken = $client->authenticate($authCode);
    // Store the credentials to disk.
    /*if(!file_exists(dirname($credentialsPath))) {
      mkdir(dirname($credentialsPath), 0700, true);
    }
    file_put_contents($credentialsPath, $accessToken);*/
    //printf("Credentials saved to %sn", $credentialsPath);
//}
$client->setAccessToken($accessToken);
// Refresh the token if it's expired.
if ($client->isAccessTokenExpired()) {
$client->refreshToken($client->getRefreshToken());
file_put_contents($credentialsPath, $client->getAccessToken());
}
return $client;
}
/**
* Expands the home directory alias '~' to the full path.
* @param string $path the path to expand.
* @return string the expanded path.
*/
function expandHomeDirectory($path) {
  $homeDirectory = getenv('HOME');
  if (empty($homeDirectory)) {
    $homeDirectory = getenv("HOMEDRIVE") . getenv("HOMEPATH");
  }
  return str_replace('~', realpath($homeDirectory), $path);
}
// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Calendar($client);

$event = new Google_Service_Calendar_Event(array(
  'summary' => $_SESSION['cal-data']['fname']." ".$_SESSION['cal-data']['lname'],
  'location' => $_SESSION['cal-data']['address'],
  'description' => "Contact: ".$_SESSION['cal-data']['phoneno']." for ".$_SESSION['cal-data']['title'],
  'start' => array(
    'dateTime' => $_SESSION['cal-data']['starttm'],
    //'timeZone' => 'America/Los_Angeles',
  ),
  'end' => array(
    'dateTime' => $_SESSION['cal-data']['endtm'],
    //'timeZone' => 'America/Los_Angeles',
  ),
  /*'recurrence' => array(
    'RRULE:FREQ=DAILY;COUNT=2'
  ),*/
  'attendees' => array(
    array('email' => $_SESSION['cal-data']['email'])
  ),
  'reminders' => array(
    'useDefault' => FALSE,
    'overrides' => array(
      array('method' => 'email', 'minutes' => 24 * 60),
      array('method' => 'popup', 'minutes' => 10),
    ),
  ),
));
$calendarId = 'xxxxxxxxxxxxxxxxxxxxx@group.calendar.google.com';
$event = $service->events->insert($calendarId, $event);
//printf('Event created: %sn', $event->htmlLink);
unset($_SESSION['cal-data']);
header("Location: next-page.php");

有一种方法可以将凭据存储在共享/公共日历中，使用日历 ID，就像在"普通"API 调用中一样。

POST https://www.googleapis.com/calendar/v3/calendars/YOUR_SHARED_CALENDAR_ID/events

但是，您必须与这些人或公众共享日历。 https://support.google.com/calendar/answer/37082?hl=en

否则你不能

您可以使用服务帐户充当访问日历的代理用户（不再提示用户登录其帐户）。根据使用服务帐号插入 Google 日历条目，您可以将活动添加到共享日历。

以下是步骤：

创建服务帐户
您需要创建一个公钥/私钥对。

在"创建服务帐户
"窗口中，键入服务帐户的名称，然后选择"提供新的私钥"。如果您想向服务帐号授予 Google Apps 全网域权限，还要选择启用 Google Apps 全网域委派。

注意：启用 API 并将日历从服务帐号凭据共享到您的电子邮件地址。并且不要忘记启用"事件更改"。
