SwiftMailer 测试用户名和密码

Question

我真的不知道这是否是关于SwiftMailer或mailtrap.io但问题是当我尝试建立到所述服务的 SMTP 连接时 ( mailtrap.io) 我从来没有收到任何错误，即使我不使用任何用户名或密码。不使用任何用户名或密码时，我不应该收到任何身份验证错误吗？还是我这样做是错误的？这是我在将其存储到.env文件中之前用于测试是否可以建立动态连接的方法。/** * E-mail configuration * * @param Request $request * @return \Illuminate\Routing\Redirector|\Illuminate\Http\RedirectResponse */public function postEmailConfiguration(Request $request){    # Try connecting to the SMTP    try {        $encryption = $request->input('encryption');        if ($encryption == 'null') {            $encryption = NULL;        }        $transport = new Swift_SmtpTransport($request->input('host'), $request->input('port'), $encryption);        $transport->setUsername($request->input('username'));        $transport->setPassword($request->input('password'));        $mailer = new Swift_Mailer($transport);        $mailer->getTransport()->start();        # Update .env file        $this->setEnvironmentValues([            'MAIL_HOST' => $request->input('host'),            'MAIL_PORT' => $request->input('port'),            'MAIL_USERNAME' => $request->input('username'),            'MAIL_PASSWORD' => $request->input('password'),            'MAIL_ENCRYPTION' => $request->input('encryption')        ]);        return redirect()->back()->with('success', 'Connection to SMTP establised and saved!');    }    # Could not connect to SMTP    catch (Swift_TransportException $e) {        return redirect()->back()->with('error', 'Could not connect to SMTP server.<br>Error: ' . $e->getMessage());    }    # Could not connect to SMTP    catch (Exception $e) {        return redirect()->back()->with('error', 'Could not connect to SMTP server.<br>Error: ' . $e->getMessage());    }}

我在 Symfony 4.4 上使用SwiftMailer 6测试了与 Gmail 的连接，下面的代码（与您的类似）对我来说按预期工作。

因此，如果您想检查是否在没有消息发送的情况下建立了连接，请使用下一个代码：

public function checkConnection()

{

    try {

        // Create the Transport

        $transport = (new \Swift_SmtpTransport(

            'smtp.gmail.com',

            '587',

            'tls'

        ))

            ->setUsername('[e-mail]')

            ->setPassword('yourSuperPassword');

        // Create the Mailer using your created Transport

        $mailer = new \Swift_Mailer($transport);

        $mailer->getTransport()->start();

        return true;

    } catch (\Swift_TransportException $e) {

        return $e->getMessage();

    } catch (\Exception $e) {

        return $e->getMessage();

    }

}

否则，它会抛出异常：

Swift_TransportException:
