PHP Запрос в Android возвращает ошибку, но я не уверен, почему

0 голосов
/ 14 июля 2020

Я создаю приложение Android, которое использует базу данных MySQL для хранения учетных данных пользователя, и PHP, которое запускается на сервере XAMPP на моем локальном компьютере. Я создал поток аутентификации, который использует базу данных, и приложение Android делает это через HTTP-запросы, используя PHP.

Вчера мне удалось получить рабочую аутентификацию, которая позволила мне зарегистрировать пользователя , а затем войдите, используя учетные данные этого пользователя. Сегодня я запускаю свой сервер и go для регистрации пользователя и получаю сообщение об ошибке, записанное в Android, когда вызывается функция createUser - Unknown error occurred. Please try again!. Я проверил журналы своего сервера, и я не обнаружил сообщений об ошибках или чего-либо, что выглядит неуместно.

Кто-нибудь знает, в чем может быть проблема? Он по-прежнему позволяет мне входить в систему, используя пользователя, которого я создал вчера, когда он работал нормально, но не разрешает дальнейшие регистрации.

$db = new DB_FUNCTIONS();

$response = array("error" => FALSE);

if (isset($_POST['name']) && isset($_POST['email']) && isset($_POST['password']) && isset($_POST['phone_number'])) {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $password = $_POST['password'];
    $phone_number = $_POST['phone_number'];

    if ($db -> isExistingUser($email)) {
        $response["error"] = TRUE;
        $response["error_msg"] = "Email address is already registered. Please try signing in: " . $email;
        echo json_encode($response);
    } else {
        $user = $db -> createUser($name, $email, $password, $phone_number);
