php - Google API Oauth php 永久访问

Question

我正在使用谷歌日历 API。这就是我想要的，一旦您授予该应用程序权限，我就可以随时使用该应用程序，而无需每天都授予访问权限。我一直听说我需要保存访问 token 或使用刷新 token 来做我想做的事情。事情是这样的，你是怎么做到的？代码看起来如何？我试过将 token 保存在 cookie 中，但一个小时后，访问 token 已过期。如何让用户保持登录状态？

PS:请给我代码示例和解释。

这是我的代码(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;

    }

Ok，等了几天，Terry Seidler(评论下方)的建议让这一切都发生了!这是我的一段代码，介绍如何自动刷新访问 token ，而无需每次都使用 cookie 进行验证。

(注意:将刷新 token 保存在数据库中更安全)

这就是魔法(使用 cookie):

$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'));
    }

就是这样!如果您有任何问题，请随时在下面发表评论，我会尽我所能回答。祝你好运，干杯!
