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(){&nbsp; &nbsp; try {&nbsp; &nbsp; &nbsp; &nbsp; // Create the Transport&nbsp; &nbsp; &nbsp; &nbsp; $transport = (new \Swift_SmtpTransport(&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'smtp.gmail.com',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; '587',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'tls'&nbsp; &nbsp; &nbsp; &nbsp; ))&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->setUsername('[e-mail]')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->setPassword('yourSuperPassword');&nbsp; &nbsp; &nbsp; &nbsp; // Create the Mailer using your created Transport&nbsp; &nbsp; &nbsp; &nbsp; $mailer = new \Swift_Mailer($transport);&nbsp; &nbsp; &nbsp; &nbsp; $mailer->getTransport()->start();&nbsp; &nbsp; &nbsp; &nbsp; return true;&nbsp; &nbsp; } catch (\Swift_TransportException $e) {&nbsp; &nbsp; &nbsp; &nbsp; return $e->getMessage();&nbsp; &nbsp; } catch (\Exception $e) {&nbsp; &nbsp; &nbsp; &nbsp; return $e->getMessage();&nbsp; &nbsp; }}否则，它会抛出异常：Swift_TransportException:Failed to authenticate on SMTP server with username "[e-mail]" using 3 possible authenticators. Authenticator LOGIN returned Expected response code 235 but got code "535", with message "535-5.7.8 Username and Password not accepted.
