Question

我可以使用API密钥和OAuth 2.0客户端ID将事件添加到我的Google日历中，但我想在没有Google授权屏幕的情况下执行此操作。

我按照这篇文章中的信息：

stackoverflow.com/questions/8995451/how-do-i-connect-to-the-google-calendar-api-without-the-oauth-authentication

为此，我创建了一个＆＃39;服务帐户密钥＆＃39;。我转到了我的项目凭据并选择了“创建凭证”＆gt;服务帐户密钥＆＃39;

然后：

服务帐户＆gt; my_project_name

密钥类型＆gt; P12

我保存了密钥文件key.p12

这是我的代码：

<?php
// display error, debbug
ini_set('display_errors',1);

session_start();

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

// following values are taken from : console.developers.google.com/apis/credentials?project=projectname credentials
// OAuth 2.0 client IDs : Client ID
const CLIENT_ID = 'xxxx';
// Service account keys : Service account
const SERVICE_ACCOUNT_NAME = 'my_project_name';

// key 
const KEY_FILE = './key.p12';

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

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

// Load the key in PKCS 12 format
$key = file_get_contents(KEY_FILE);

$client->setAssertionCredentials(new Google_AssertionCredentials(
    SERVICE_ACCOUNT_NAME,
    array('https://www.googleapis.com/auth/calendar'),
    $key)
);

$client->setClientId(CLIENT_ID);
$cal = new Google_CalendarService($client);

//Save token in session
if ($client->getAccessToken()) {
    $_SESSION['token'] = $client->getAccessToken();
}

// my code here
$event = new Google_Event(...
$calendarId = 'mycalendarID@group.calendar.google.com';
$event = $cal->events->insert($calendarId, $event);

?>

以下是错误消息：

Fatal error:  Uncaught Google_AuthException: Error refreshing the OAuth2 token, message: '{
  'error' : 'invalid_client',
  'error_description' : 'The OAuth client was not found.'
}' in /home/www/google-api-php-client/src/auth/Google_OAuth2.php:288

似乎$ client-＆gt; getAccessToken（）似乎没有设置，但我不知道为什么。

提前感谢您的帮助。
