Google 日历 api CalendarList 列表 return 空列表

Question

已下载脚本 here 和设置。但是当我试图获取日历时，它 returns 是一个空列表。我想获取所有日历列表与帐户共享。请注意，有 4 个日历与我的 Gmail 帐户共享。我也关注这个 instruction.

**Code**

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


$client->setAssertionCredentials($cred);
if ($client->getAuth()->isAccessTokenExpired()) {
  $client->getAuth()->refreshTokenWithAssertion($cred);
}
$_SESSION['service_token'] = $client->getAccessToken();
$service = new Google_Service_Calendar($client);
echo "<br>=======================<br>";    
var_dump($service->calendarList->listCalendarList()); 
echo "<br>=======================<br>";    
?>

输出

当文件为 json 时，读取键值有一些变化，下面的表格是正确的代码

$key = file_get_contents($key_file_location);
$data = json_decode($key); 

    $scopes = array("https://www.googleapis.com/auth/calendar.readonly","https://www.googleapis.com/auth/calendar");
    $cred = new Google_Auth_AssertionCredentials(
        $service_account_name,
        $scopes,
        $data->private_key
    );
$client->setAssertionCredentials($cred);


try {
  $client->getAuth()->refreshTokenWithAssertion($cred);
} catch (Exception $e) {
    $e->getMessage();
}
$calendarList  = $service->calendarList->listCalendarList();
var_dump($calendarList);
