php – 使用Swiftmailer从gmail发送电子邮件

我正在尝试使用Swiftmailer从Gmail发送电子邮件,并打印此错误：

Fatal error: Uncaught exception 'Swift_TransportException' with message 'Failed to authenticate on SMTP server with username "[e-mail]" using 2 possible authenticators' in /home/websitename/public_html/cv/Swift-5.1.0/lib/classes/Swift/Transport/Esmtp/AuthHandler.PHP:184 Stack trace: #0 /home/websitename/public_html/cv/Swift-5.1.0/lib/classes/Swift/Transport/EsmtpTransport.PHP(312): Swift_Transport_Esmtp_AuthHandler->afterEhlo(Object(Swift_SmtpTransport)) #1 /home/websitename/public_html/cv/Swift-5.1.0/lib/classes/Swift/Transport/AbstractSmtpTransport.PHP(120): Swift_Transport_EsmtpTransport->_doHeloCommand() #2 /home/websitename/public_html/cv/Swift-5.1.0/lib/classes/Swift/Mailer.PHP(80): Swift_Transport_AbstractSmtpTransport->start() #3 /home/websitename/public_html/cv/profile2.PHP(69): Swift_Mailer->send(Object(Swift_Message)) #4 {main} thrown in /home/websitename/public_html/cv/Swift-5.1.0/lib/classes/Swift/Transport/Esmtp/AuthHandler.PHP on line 184

我的PHP代码：

require_once 'Swift-5.1.0/lib/swift_required.PHP';
$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl")
      ->setUsername('[e-mail]')
      ->setPassword('password');

    $mailer = Swift_Mailer::newInstance($transport);
    $message = Swift_Message::newInstance('Wonderful Subject')
      ->setFrom(array('[e-mail]' => 'Ahmad Shadeed'))
      ->setTo(array('[e-mail]' => 'YOU'))
      ->setBody('This is the text of the mail send by Swift using SMTP transport.');
    $numSent = $mailer->send($message); 

Anyhelp解决这个问题好吗？

谢谢,

解决方法:

去

https://www.google.com/settings/security/lesssecureapps

同时登录SMPT配置的gmail帐户

这里

->setUsername('[e-mail]')
->setPassword('password');

并启用“访问不太安全的应用程序”
