我一直在尝试使用 PHP 访问 Google Calendar API v3。最初，我想简单地列出我对 API 的调用可以访问的用户日历。

为此，我下载了 Google API PHP 客户端库并尝试使用以下代码（经过我的修改，该代码来自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 = '754674507864-pm1dsgdsgsdfsdfsdfdflg6lt9a@developer.gserviceaccount.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);

?>

我在 Google Developers 控制台中创建了一个服务帐户，并生成了 OAuth 详细信息，我用它来设置适当的变量，从代码中可以看出。

此代码返回以下内容：

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] => bots@madeupcompany.co.uk [summary] => bots@madeupcompany.co.uk [timeZone] => Europe/London [colorId] => 23 [backgroundColor] => #cd74e6 [foregroundColor] => #000000 [selected] => 1 [accessRole] => reader [defaultReminders] => Array ( ) ) ) ) [processed:protected] => Array ( ) )

问题是这似乎只返回一个日历的详细信息。也就是说，bots@madeupcompany.co.uk 的日历（我明确与我的服务共享的唯一一个）。

但是，我知道这个 google 帐户对许多其他用户的日历具有只读访问权限（我可以在以该用户身份登录 Google 日历时看到它们）。

此外，如果我在此页面上使用 Google Apps Explorer：https ://developers.google.com/google-apps/calendar/v3/reference/calendarList/list#auth ，同时以 bots@madeupcompany 身份登录我的 Google 帐户。 co.uk，我得到了所有这些其他日历的详细信息。

所以我正在努力解决，为什么应用程序资源管理器向我显示所有其他日历，而 PHP 代码却没有？

服务帐户不需要提示用户访问，因为您必须对其进行设置。访问 Google 日历网站。找到日历设置，然后转到日历选项卡，找到您要访问的日历并单击“共享：编辑设置”添加服务帐户电子邮件地址，就像您添加个人电子邮件地址一样。这将为服务帐户提供与您与任何其他用户共享该服务帐户相同的访问权限。
