我尝试使用Google API for PHP 2.2.0版本连接到Google日历。直到现在，我还没有成功地连接到我的日历，这是非常令人沮丧的。
此时，我收到以下致命错误：
致命错误：Uncaught InvalidArgumentException：json key is missing the type field in /home/servi471/public_html/wp-content/plugins/google-api-php-client-2.2.0/vendor/google/auth/src/CredentialsLoader.php：123堆栈跟踪：Copyright © 2018 - 2019 www. cn-servi.com.

我使用这个代码：

require_once WP_PLUGIN_DIR . '/google-api-php-client-2.2.0/vendor/autoload.php';
require_once WP_PLUGIN_DIR . '/google-api-php-client-2.2.0/src/Google/Client.php';
require_once WP_PLUGIN_DIR . "/google-api-php-client-2.2.0/vendor/google/apiclient-services/src/Google/Service/Calendar/Resource/CalendarList.php";
require_once WP_PLUGIN_DIR . "/google-api-php-client-2.2.0/vendor/google/apiclient-services/src/Google/Service/Oauth2.php";

putenv('GOOGLE_APPLICATION_CREDENTIALS=' . dirname(__FILE__) . '/oauth-credentials.json');

$client = new Google_Client();
$redirect_uri = 'https://myredirect-uri';
$client->setRedirectUri($redirect_uri);

$client->setRedirectUri($redirect_uri);
$client->setClientId('myclient-di.apps.googleusercontent.com');
$client->setClientSecret('myclient-secret');
$client->setAccessType("offline");        // offline access
$client->setIncludeGrantedScopes(true);   // incremental auth
$client->addScope(Google_Service_Calendar::CALENDAR);

$user_to_impersonate = 'owner-of-agenda@gmail.com';
$client->setSubject($user_to_impersonate);
$client->setAuthConfig(GOOGLE_APPLICATION_CREDENTIALS);

$client->useApplicationDefaultCredentials();

if (file_exists(CREDENTIALS_PATH)) {
    $token = file_get_contents(CREDENTIALS_PATH);
    echo "<h4>_Token</h4>";
    var_dump($token);
    $client->setAccessToken($token);
}
echo "<br><br>CLIENT";

$service = new Google_Service_Calendar($client);

$calendarList = $service->calendarList->listCalendarList();
var_dump($calendarList);

echo "<h4>End of example</h4>";

我看到生成了一个令牌。
有人能帮我联系一下吗？
