PHPMailer SMTP Connect Error

问题

I'm trying to setup PHPMailer in AWS. It returns error saying SMTP connect() failed.

Code

<?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!";
}

?>

Finally, I resolved my issue. I have found some useful resources during the process (which may cause similar issues during SMTP authentication.)

Solution You have to include PHPMailerAutoload.php file to the code even if you are using composer.

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

Join the group Allow Risky Access Permissions By Unreviewed Apps in order to execute unreviewed / development / single SMTP authenticated applications. You can read more about it from here.
