我目前使用的是 谷歌日历API 的网络应用。但是，每隔一个小时，我就会被提示一个验证快速启动访问的链接。有人知道如何解决这个问题吗？
详情请看。
我试过用OAUTH和服务账号，都没有效果。 任何帮助是非常感激的。
以下是使用服务账户的凭证创建Google_Client和Srvice对象的代码。
function __construct()
{
Service account based client creation.
$this->client = new Google_Client();
$this->client->setApplicationName("Redu");
$this->client->setAuthConfig(CREDENTIALS_PATH);
$this->client->setScopes([SCOPES]);
$this->client->setSubject('[email protected]');
$this->client->setAccessType('offline');
$this->service = new Google_Service_Calendar($this->client);
}
当我试图使用$service对象创建一个日历或创建一个事件时，我得到一个错误，说域范围的权限没有设置。 然而，当我创建服务帐户时，我确实启用了域范围的授权。
EDIT:
下面是我的代码，使用服务账户密钥创建一个Google_Client，并使用客户端为[email protected] 创建一个新的日历。请注意，我将[email protected]的日历与[email protected]共享，并将权限设置为 "管理更改和管理共享"。 我得到的错误就在下面的代码中。
require (__DIR__.'/../../../vendor/autoload.php');
define('CREDENTIALS_PATH', __DIR__ . '/redu_service_account_credentials.json');
define('SCOPES', Google_Service_Calendar::CALENDAR);
function createNewCalendar($userName) {
//Service account based client creation.
$client = new Google_Client();
$client->setApplicationName("REdu");
// path to the credentials file obtained upon creating key for service account
$client->setAuthConfig(CREDENTIALS_PATH);
$client->setScopes([SCOPES]);
$client->setSubject('[email protected]');
$client->setAccessType('offline');
$service = new Google_Service_Calendar($client);
$calendar = new Google_Service_Calendar_Calendar();
$calendar->setSummary($userName);
$calendar->setTimeZone('America/Los_Angeles');
$createdCalendar = $service->calendars->insert($calendar);
// Make the newly created calendar public
$rule = new Google_Service_Calendar_AclRule();
$scope = new Google_Service_Calendar_AclRuleScope();
$scope->setType("default");
$scope->setValue("");
$rule->setScope($scope);
$rule->setRole("reader");
// Make the calendar public
$createdRule = $service->acl->insert($createdCalendar->getId(), $rule);
return $createdCalendar->getId();
}
ERROR:
Fatal error: Uncaught exception 'Google_Service_Exception' with message '{

"error_description": "Client is unauthorized to retrieve access tokens using this method, or client not authorized for any of the scopes requested."

Oauth2和服务账户是两码事。 如果你试图访问一个用户的数据，你使用oauth2。你提到的同意窗口将被撑起，并要求他们允许你的应用程序访问他们的数据。
另一方面，服务账户是虚拟用户，他们可以被预先批准访问你这个开发者控制的数据。 你可以与一个服务账户共享一个日历，授予它访问该日历的权限，它将不需要像用户一样进行身份验证。
一个服务账户将永远不会弹出并再次请求访问。
问题是你的访问令牌正在过期。 如果它过期了，那么用户将需要再次授予你的应用程序对其数据的访问权。为了避免这种情况，我们使用刷新令牌，并将其存储在一个会话变量中，当访问令牌过期时，我们只需请求一个新的令牌。
请注意我是如何请求 $client->setAccessType("offline"); 这将给我一个刷新标记。
会话变量现在被设置为存储这些数据。
$_SESSION['access_token'] = $client->getAccessToken();
$_SESSION['refresh_token'] = $client->getRefreshToken();
然后，我可以检查访问令牌是否过期，如果过期，我就刷新它。
if ($client->isAccessTokenExpired()) {
$client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
$client->setAccessToken($client->getAccessToken());
$_SESSION['access_token'] = $client->getAccessToken();
}
require_once __DIR__ . '/vendor/autoload.php';
require_once __DIR__ . '/Oauth2Authentication.php';
// Start a session to persist credentials.
session_start();
// Handle authorization flow from the server.
if (! isset($_GET['code'])) {
$client = buildClient();
$auth_url = $client->createAuthUrl();
header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {
$client = buildClient();
$client->authenticate($_GET['code']); // Exchange the authencation code for a refresh token and access token.
// Add access token and refresh token to seession.
$_SESSION['access_token'] = $client->getAccessToken();
$_SESSION['refresh_token'] = $client->getRefreshToken();
//Redirect back to main script
$redirect_uri = str_replace("oauth2callback.php",$_SESSION['mainScript'],$client->getRedirectUri());
header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));

客户端未经授权使用此方法检索访问令牌，或者客户端未被授权使用任何请求的范围。
有两种类型的客户端Oauth2客户端和服务账户客户端。 你下载的.json文件对于每个客户端都是不同的。 就像你将为每个客户端使用的代码一样。 你不能交换这些代码。
你得到的错误统计，你正在使用的客户端不能用于你正在使用的代码。 试着再次下载服务账户的客户端秘密.json......。
