問題描述
我開始在我的新應用程序上配置谷歌日歷.我幾乎制作了谷歌開發者展示的身份驗證代碼的精確副本(https://developers.google.com/google-apps/calendar/instantiate )，但我不斷收到以下錯誤:
I started to configure google calendar on my new application. I almost made an exact copy of the authentication code displayed at google developers ( https://developers.google.com/google-apps/calendar/instantiate ), but i keep getting the following error:
獲取 OAuth2 訪問令牌時出錯，消息:'invalid_grant'
Error fetching OAuth2 access token, message: 'invalid_grant'
我目前使用 Fork-CMS ( http://www.fork-cms.com)，一個年輕的輕量級 CMS.我正確配置了 google-api-php-client 的 config.php 文件.(client-id, client-secret, redirect-uri, development key,...) 并且在 google api 的控制臺上正確設置了重定向 uri.我的代碼如下所示:
I'm currently using Fork-CMS ( http://www.fork-cms.com ), a young lightweigth CMS. I correctly configured the config.php file of the google-api-php-client. (client-id, client-secret, redirect-uri, development key,...) and the redirect uri is correctly set on the google api's console. My code looks as follows:
<?php
/**
* This is a widget with a calendar implementation.
*
* @package frontend
* @subpackage events
*
* @author Michiel Vlaminck <michielvlaminck@gmail.com>
*/
class FrontendEventsWidgetCalendar extends FrontendBaseWidget
{
private $events = array();
private $authUrl = array();
/**
* Execute the extra
*
* @return void
*/
public function execute()
{
// call parent
parent::execute();
// load template
$this->loadTemplate();
// get data
$this->getData();
// parse
$this->parse();
}
/**
* Get the data from Google Calendar
* This method is only executed if the template isn't cached
*
* @return void
*/
private function getData()
{
require_once PATH_LIBRARY . '/external/google-api-php-client/src/apiClient.php';
require_once PATH_LIBRARY . '/external/google-api-php-client/src/contrib/apiCalendarService.php';
$client = new apiClient();
$service = new apiCalendarService($client);
if (isset($_SESSION['oauth_access_token'])) {
$client->setAccessToken($_SESSION['oauth_access_token']);
} else {
$token = $client->authenticate();
$_SESSION['oauth_access_token'] = $token;
}
if ($client->getAccessToken()) {
$calId = FrontendEventsModel::getCalendarId((int) $this->data['id']);
$calId = $calId[0]['calendar_id'];
$events = $service->events->listEvents($calId);
$this->events = $events['items'];
$_SESSION['oauth_access_token'] = $client->getAccessToken();
} else {
$this->authUrl = $client->createAuthUrl();
}
}
/**
* Parse
*
* @return void
*/
private function parse()
{
$this->tpl->assign('events', $this->events);
$this->tpl->assign('authUrl', $this->authUrl);
}
}
?>
當我第一次打開這個小部件頁面時，我被引導到谷歌來驗證應用程序.當我同意時，我被重定向到我的應用程序，這就是我得到的點:
When I open this widget-page for the first time, I get directed to google to authenticate the application. When I agree, I get redirected to my application and that's the point where I'm getting:
apiAuthException ? Main
Message Error fetching OAuth2 access token, message: 'invalid_grant'

推薦答案
您應該重復使用在第一次成功驗證后獲得的訪問令牌.如果您之前的令牌尚未過期，您將收到 invalid_grant 錯誤.將其緩存在某處，以便您可以重復使用.
You should reuse the access token you get after the first successful authentication. You will get an invalid_grant error if your previous token has not expired yet. Cache it somewhere so you can reuse it.
