我正在使用 Google Calendar API 在 fullcalendar 上显示事件(因此在我的视图中使用 json 对象)。我正在使用 codeignitor php 框架,我的控制器中有一些函数来创建一个新客户端,然后我在 oauth2callback() 函数中使用它来将我的代码交换为 access_token 然后我开始在 gcalendar() 中调用服务并gcalendar_events。我已将 accessType 设置为离线,但这似乎并没有让我离线访问事件。效果很好,只是每次会话结束时我都会被重定向到再次登录。我不希望这样,我希望它们在会话结束后一直显示。我正在尝试使用刷新令牌以防 access_token 过期以查看是否可以解决问题。
这是我控制器中的代码
function getClient() {
$client = new Google_Client();
$client->setApplicationName("DL Calendar");
$client->setAuthConfig('application/client_secrets.json');
$client->addScope('profile');
$client->setIncludeGrantedScopes(true);
$client->setAccessType('offline');
return $client;
}
function gcalendar() {
$this->load->add_package_path(APPPATH . 'vendor/autoload');
$client = $this->getClient();
//$client->setRedirectUri(site_url('calendar/index'));
$client->addScope(Google_Service_Calendar::CALENDAR);
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
$client->setAccessToken($_SESSION['access_token']);
$access_token = $_SESSION['access_token'];
$service = new ]Google_Service_Calendar($client);
$calendar = new Google_Service_Calendar_Calendar();
//$calendarList = $service->calendarList->listCalendarList();
$calendar = $service->calendars->get('primary');
$params = array(
'owner_id' => get_current_user_id(),
'title' => get_current_user(). ' ' .'Google Calendar',
'type' => 'gcal',
'url' => $calendar->id,
);
$calendar_id = $this->Calendar_model->add_calendar($params);
redirect('calendar/index');
} else {
$redirect_uri = site_url('calendar/oauth2callback');
header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}
$this->session->set_flashdata('success', 'Event Successfully Added');
}
函数 oauth2callback() {
//Build the client object
$client = $this->getClient();
$client->addScope(Google_Service_Calendar::CALENDAR);
$service = new Google_Service_Calendar($client);
$url = parse_url($_SERVER['REQUEST_URI']); parse_str($url['query'], $params);
$code = $params['code'];
//To exchange an authorization code for an access token, use the authenticate method:
if (! isset($code)) {
$auth_url = $client->createAuthUrl();
header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {
$token = $client->fetchAccessTokenWithAuthCode($code);
$client->setAccessToken($token);
$client->authenticate($code);
$_SESSION['access_token'] = $client->getAccessToken();
$redirect_uri = site_url('calendar/gcalendar');
header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}
}
function gcalendar_events() {
$client = $this->getClient();
$client->addScope(Google_Service_Calendar::CALENDAR);
// $client->setRedirectUri(site_url('calendar/gcalendar'));
$client->setAccessType('offline'); //need calendar events to appear even if not logged in to google
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
$client->setAccessToken($_SESSION['access_token']);
$access_token = $_SESSION['access_token'];
$service = new Google_Service_Calendar($client);
$id = 'primary';
$calendar = new Google_Service_Calendar_Calendar();
$calendar = $service->calendars->get('primary');
$event = new Google_Service_Calendar_Event();
$events = $service->events->listEvents($id);
foreach ($events->getItems() as $event) {
$startTime = strtotime($event->getStart()->dateTime) ;
$endTime = strtotime($event->getEnd()->dateTime);
$start = date('Y-m-d H:i:s', $startTime);
$end = date('Y-m-d H:i:s', $endTime);
$eventsArr[] = array(
'title' => $event->getSummary(),
'start'=> $start,
'end' => $end,
);
}
// Return a single `events` with all the `$eventsArr`
echo json_encode($eventsArr);
}
}
我的会话中的问题是否结束?或者访问令牌是否过期并且我需要刷新令牌?我在哪里设置刷新令牌,因为我尝试将它放在多个地方,但我收到一条错误消息,提示必须将刷新令牌设置为 setAccessToken 的一部分。我把它全部放完,仍然收到错误消息。
这是我使用的代码
if ($client->isAccessTokenExpired()) {
$refresh_token = $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
$client->setAccessToken($refresh_token);
$_SESSION['access_token'] = $refresh_token;
$this->load->helper('file');
write_file('application/client_secrets.json', json_encode($client->getAccessToken()));
} else {
$access_token = $_SESSION['access_token'];
}
我只是注意到它曾经在我的授权中说“授予离线访问权限”,但现在它不再提到虽然谷歌文档说
用户授予对请求范围的离线访问权限后,您可以在用户离线时继续使用 API 客户端代表用户访问 Google API。客户端对象将根据需要刷新访问令牌。
