PHPMailer SMTP连接错误

Question

我试图在AWS中设置PHPMailer。它返回SMTP连接()失败的错误。

码

<?php
require 'vendor/autoload.php';
$mail = new PHPMailer;
$mail->isSMTP();
$mail->SMTPDebug =2;
$mail->Debugoutput = 'html';
$mail->Host = 'smtp.gmail.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->AuthType = 'XOAUTH2';
$mail->oauthUserEmail = "xxx@gmail.com";
$mail->oauthClientId = "client-key.apps.googleusercontent.com";
$mail->oauthClientSecret = "secretkey";
$mail->oauthRefreshToken = "refresh_token";
$mail->setFrom('tittuonnet@gmail.com', 'ParkIt');
$mail->addAddress("tittuhpd@gmail.com", "Tittu Varghese");
$mail->Subject = 'ParkIt - Verification Code';
$mail->Body = 'Please verify your account';

$mail->send();
if (!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message sent!";
}

?>

最后，我解决了我的问题。在此过程中，我发现了一些有用的资源(这可能会在SMTP身份验证期间引起类似的问题)。

解决方案--即使您使用的是composer，也必须将PHPMailerAutoload.php文件包含到代码中。

require 'PHPMailer/PHPMailerAutoload.php';
require 'vendor/autoload.php';

加入组允许未经评审的应用程序进行高风险访问权限，以执行未评审/开发/单个SMTP身份验证应用程序。你可以从这里上读到更多关于它的信息。
