在本地主機上使用 PHPMailer SMTP 發送郵件失敗

Question

我想在我的網站上有一個簡單的 email 驗證系統。

有人告訴我使用 PHPMailer 來執行此操作，但發送實際的 email 似乎總是失敗，我無法弄清楚很多配置可能性實際上在做什么。

這是我得到的錯誤：

如果我嘗試使用 localhost 執行此操作，這是我得到的錯誤。 我正在使用 XAMPP 與 Apache 和 MySql 但我還沒有安裝“水星”，因為我真的不明白這一切是如何工作的。

最后，我希望在這里在線托管： OpenStringStudios ，所以我不明白“水星”在這方面與任何事情有什么關系。

這是我正在使用的 php 代碼：

<?php
    use PHPMailer\PHPMailer\PHPMailer;
    use PHPMailer\PHPMailer\SMTP;
    use PHPMailer\PHPMailer\Exception;

    // echo "Hello World!";

    if (isset($_POST['submit'])) {
        $con = new mysqli('localhost', 'root', '', 'osscom_users_test');

        $name = $con->real_escape_string($_POST['name']);
        $email = $con->real_escape_string($_POST['email']);
        $pass = $con->real_escape_string($_POST['pass']);

        // test if the username is already taken
        // one email addresses can have multiple users

        $token = 'qwertzuiopasdfghjklyxcvbnmQWERTZUIOPASDFGHJKLYXCVBNM0123456789';
        $token = str_shuffle($token);
        $token = substr($token, 0, 10);

        $hashedPass = password_hash($pass, PASSWORD_BCRYPT);

        $con->query("INSERT INTO test_users (NAME, EMAIL, PASSWORD, VERIFIED, TOKEN)
            VALUES ('$name', '$email', '$hashedPass', '0', '$token');
        ");

        include_once "PHPMailer/PHPMailer.php";
        include_once "PHPMailer/Exception.php";
        include_once "PHPMailer/SMTP.php";

        try {
            // Server settings
            $mail = new PHPMailer();

            $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      // Enable verbose debug output
            $mail->isSMTP();                                            // Send using SMTP
            $mail->Host       = 'smtp.gmail.com';                       // Set the SMTP server to send through
            $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
            $mail->Username   = 'root';                                 // SMTP username
            $mail->Password   = '';                                     // SMTP password
            $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` also accepted
            $mail->Port       = 587;                                    // TCP port to connect to

            $mail->setFrom('openstring.studios@gmail.com', 'OpenString Team');
            $mail->addAddress($email, $name);
            $mail->isHTML(true);
            $mail->Subject = "Welcome To The OpenString Membership, Please Verify Your Account";
            $mail->Body = "
                <h1>Welcome To The OpenString Membership</h1>
                Thanks for joining, please click the link below to verify your account.<br>

                <a href='localhost/session/activation?email=$email&token=$token'>Click Here To Activate Your Account.</a>

            ";
            $mail->send();
            echo 'Message has been sent';
        } catch(Exception $e) {
            echo "Message could not be sent. Mailer Error: {$mail->ErrofInfo}";
        }

        // Redirect('account', false);
    }

    function Redirect($url, $permanent = false) {
        if (headers_sent() === false) {
            header('Location: ' . $url, true, ($permanent === true) ? 301 : 302);
        }
        exit();
    }
?>

我真的不明白如何解決這個問題。 對我來說特別重要的是，它既可以用於我的本地主機，也可以用於托管在 domain.com 上。
