Parse.com PHP 在注册或登录后不会让用户保持会话

Question

所以我将Parse.com与PHP一起用于我的用户系统，但它并没有按预期工作。当我调用signUp()方法时，新用户会成功保存在Parse DB中并登录，但如果我导航到另一个页面，ParseUser::getCurrentUser()似乎不会获取当前用户。ParseUser::logIn()方法也会发生同样的情况。这是我的部分代码：

<?php
            require 'vendor/autoload.php'; 
            use ParseParseClient;
            ParseClient::initialize('*, *, *');
            use ParseParseUser;
            use ParseParseException;
            use ParseParseSessionStorage;
            function showForm() {
                echo "
                <form action='user.php' method='POST'>
                    Όνομα (χωρίς #)<br />
                    <input type='text' name='name' required><br /><br />
                    Κωδικός πρόσβασης<br />
                    <input type='password' name='password' required><br /><br />
                    <input type='submit' name='login' value='Σύνδεση'> <input type='submit' name='register' value='Εγγραφή'>
                </form>
                ";
            }
            if ($_SERVER['REQUEST_METHOD'] == "POST") {
                if (isset($_POST['login'])) {
                    try {
                        $user = ParseUser::logIn($_POST['name'], $_POST['password']);
                        echo "<a href='add.php'>Continue</a>";
                        $currentUser = ParseUser::getCurrentUser();
                        echo $currentUser->getUsername();
                    } catch (ParseException $error) {
                        echo "Error: " . $ex->getCode() . " " . $ex->getMessage();
                        showForm();
                    }
                } else if (isset($_POST['register'])) {
                    $user = new ParseUser();
                    $user->set("username", $_POST['name']);
                    $user->set("password", $_POST['password']);
                    try {
                        $user->signUp();
                        echo "Εγγραφήκατε επιτυχώς!";
                        $currentUser = ParseUser::getCurrentUser();
                        echo $currentUser->getUsername();
                    } catch (ParseException $ex) {
                        echo "Error: " . $ex->getCode() . " " . $ex->getMessage();
                        showForm();
                    }
                }
            } else {
                showForm();
            }
        ?>

问题是我忘了在需要会话的每个页面中将session_start();放在require 'vendor/autoload.php';之后。
