如何使用Google Calendar API v3/Google API客户端库显示* all *可用日历的列表？

我一直在尝试使用PHP访问Google Calendar API v3。最初，我想简单地列出可以访问API的用户日历。如何使用Google Calendar API v3/Google API客户端库显示* all *可用日历的列表？

要做到这一点，我已经下载了谷歌API PHP客户端库，并已尝试使用下面的代码（这是采购的，用我的改编，从https://mytechscraps.wordpress.com/2014/05/15/accessing-google-calendar-using-the-php-api/）：

<?php 

//error_reporting(0); 
//@ini_set('display_errors', 0); 

// If you've used composer to include the library, remove the following line 
// and make sure to follow the standard composer autoloading. 
// https://getcomposer.org/doc/01-basic-usage.md#autoloading 
require_once './google-api-php-client-master/autoload.php'; 

// Service Account info 
$client_id = '754612121864-pmdfssdfakqiqblg6lt9a.apps.googleusercontent.com'; 
$service_account_name = '[email protected]nt.com'; 
$key_file_location = 'Calendar-7dsfsdgsdfsda953d68dgdsgdsff88a.p12'; 


$client = new Google_Client(); 
$client->setApplicationName("Calendar"); 

$service = new Google_Service_Calendar($client); 

$key = file_get_contents($key_file_location); 
$cred = new Google_Auth_AssertionCredentials(
$service_account_name, 
array('https://www.googleapis.com/auth/calendar.readonly'), 
$key 
); 

$client->setAssertionCredentials($cred); 

$cals = $service->calendarList->listCalendarList(); 
print_r($cals); 

?>

我创建了一个服务Google Developers控制台中的帐户以及生成的OAuth详细信息，这些详细信息用于设置可从代码中看到的适当变量。

此代码返回如下：

Google_Service_Calendar_CalendarList Object ([collection_key:protected] => items [internal_gapi_mappings:protected] => Array () [etag] => "14171313334000" [itemsType:protected] => Google_Service_Calendar_CalendarListEntry [itemsDataType:protected] => array [kind] => calendar#calendarList [nextPageToken] => [nextSyncToken] => 000014121268327000 [modelData:protected] => Array ([items] => Array ([0] => Array ([kind] => calendar#calendarListEntry [etag] => "1417721316542000" [id] => [email protected] [summary] => [email protected] [timeZone] => Europe/London [colorId] => 23 [backgroundColor] => #cd74e6 [foregroundColor] => #000000 [selected] => 1 [accessRole] => reader [defaultReminders] => Array ()))) [processed:protected] => Array ())

的问题是，这似乎是只返回一个日历的细节。也就是[email protected]的日历（我唯一明确与我的服务共享的日历）。

但是，我知道这个Google帐户对多个其他用户的日历拥有只读权限（我可以在以该用户身份登录Google日历时看到他们）。

而且，如果我使用谷歌Apps的浏览器这个页面上：https://developers.google.com/google-apps/calendar/v3/reference/calendarList/list#auth，同时登录到我的谷歌帐户[email protected]，我得到的所有这些其他日历的详细信息。

所以我试图解决，为什么Apps Explorer向我展示所有其他日历，但PHP代码不是？

您是否尝试过通过日历服务添加日历本身并检查那些被上市？ https://developers.google.com/google-apps/calendar/v3/reference/calendars/insert – 2014-12-05 19:21:22

服务帐户不需要提示用户进行访问，因为您必须对其进行设置。转到Google日历网站。找到日历设置，然后转到日历选项卡，找到您想要访问的日历，然后点击“共享：编辑设置”添加服务帐户的电子邮件地址，就像您的个人电子邮件地址一样。这将为服务帐户提供与其他用户共享服务帐户相同的访问权限。
