问题描述

这是我的代码:

<?php
require_once 'Swift/lib/swift_required.php';

$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465)
  ->setUsername('me@ff.com')
  ->setPassword('pass');

$mailer = Swift_Mailer::newInstance($transport);
$message = Swift_Message::newInstance('Wonderful Subject')
  ->setFrom(array('me@ff.com' => 'MY NAME'))
  ->setTo(array('you@ss.com' => 'YOU'))
  ->setBody('This is the text of the mail send by Swift using SMTP transport.');
//$attachment = Swift_Attachment::newInstance(file_get_contents('path/logo.png'), 'logo.png');  
//$message->attach($attachment);
$numSent = $mailer->send($message);
printf("Sent %d messages
", $numSent);
?>

运行后出现此错误...

推荐答案

GMail 的 SMTP 需要加密.使用:

GMail's SMTP requires encryption. Use:

Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl");
