我使用的是谷歌日历API。 这就是我想要的，一旦你给应用程序的权限，我随时可以使用的应用程序，而无需访问日常给予。 我不断听到，我需要保存访问令牌或使用刷新标记做我想做的事。这里是东西，你怎么办呢？ 如何代码是什么样子？ 我试过保存令牌在cookie中，但一个小时后，访问令牌已过期。 如何保持登录的用户？
PS：请给我的代码示例与解释。
这里是我的代码（使用CakePHP）：
$client = new Google_Client();
$client->setApplicationName("Wanda3.0 Agenda");
$cal = new Google_CalendarService($client);
if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['token'] = $client->getAccessToken();
header('Location: http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']);
}
if (isset($_SESSION['token'])) { $client->setAccessToken($_SESSION['token']); }
if ($client->getAccessToken()) {
/************* Code entry *************/
}else{
/************* Not connected to google calendar code *************/
$authUrl = $client->createAuthUrl();
$returnArr = array('status' => 'false', 'message' => "<a class='login' href='$authUrl'>Connect Me!</a>");
return $returnArr;
}
好吧，等待了几天后，特里塞德勒（下面的注释）的建议，使这一切发生！ 下面是我对如何全自动刷新访问令牌无需通过cookie每次autenticating一段代码。
（注意：它的安全保存刷新令牌在数据库中）
这是（使用cookie）魔术：
$client = new Google_Client();
$client->setApplicationName("Wanda3.0 Agenda");
$cal = new Google_CalendarService($client);
$client->setAccessType('offline');
if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['token'] = $client->getAccessToken();
header('Location: http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']);
}
//Where the magic happends
if (isset($_SESSION['token'])) {
//Set the new access token after authentication
$client->setAccessToken($_SESSION['token']);
//json decode the session token and save it in a variable as object
$sessionToken = json_decode($_SESSION['token']);
//Save the refresh token (object->refresh_token) into a cookie called 'token' and make last for 1 month
$this->Cookie->write('token', $sessionToken->refresh_token, false, '1 month');
}
//Each time you need the access token, check if there is something saved in the cookie.
//If $cookie is empty, you are requested to get a new acces and refresh token by authenticating.
//If $cookie is not empty, you will tell the client to refresh the token for further use,
// hence get a new acces token with the help of the refresh token without authenticating..
$cookie = $this->Cookie->read('token');
if(!empty($cookie)){
$client->refreshToken($this->Cookie->read('token'));
}
而这就是它！ 如果您有任何疑问，请随时向下面发表评论，我会回答尽我所能。 好运和欢呼声！
而不是使用cookie和session的，你应该把它保存在数据库中，并使用它。
类似的实施Drupal站点是在谷歌的OAuth2沙盒http://drupal.org/sandbox/sadashiv/1857254此模块可让您从处理的Drupal管理界面的身份验证。 然后，可以使用所获取的访问令牌从谷歌，然后用google_oauth2_account_load的API函数或google_oauth2_client_get得到Google_Client并携带您的API调用。
一样一样的希望产业，但测试后，我只是想刷新令牌，当我不得不。 完整的源只是改变顶部的按键等：
require_once 'google-api-php-client/src/Google_Client.php';
require_once 'google-api-php-client/src/contrib/Google_CalendarService.php';
session_start();
$client = new Google_Client();
$client->setApplicationName("Google Calendar PHP Starter Application");
// Visit https://code.google.com/apis/console?api=calendar to generate your
// client id, client secret, and to register your redirect uri.
$client->setClientId('your_id');
$client->setClientSecret('your_secret');
$client->setRedirectUri("http://localhost/your_redirect.php");
$client->setDeveloperKey('your_key');
$cal = new Google_CalendarService($client);
if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['token'] = $client->getAccessToken();
header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'] . $query_string);
}
if (isset($_SESSION['token'])) {
$client->setAccessToken($_SESSION['token']);//update token
//json decode the session token and save it in a variable as object
$sessionToken = json_decode($_SESSION['token']);
//Save the refresh token (object->refresh_token) into a cookie called 'token' and make last for 1 month
if (isset($sessionToken->refresh_token)) { //refresh token is only set after a proper authorisation
$number_of_days = 30 ;
$date_of_expiry = time() + 60 * 60 * 24 * $number_of_days ;
setcookie('token', $sessionToken->refresh_token, $date_of_expiry);
}
}
else if (isset($_COOKIE["token"])) {//if we don't have a session we will grab it from the cookie
$client->refreshToken($_COOKIE["token"]);//update token
}
if ($client->getAccessToken()) {
$calList = $cal->calendarList->listCalendarList();
print "<h1>Calendar List</h1><pre>" . print_r($calList, true) . "</pre>";
$_SESSION['token'] = $client->getAccessToken();
} else {
$authUrl = $client->createAuthUrl();
print "<a class='login' href='$authUrl'>Select a calendar!</a>";
}
