My script

<?php

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

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 = "info@modelunitednation.org";
$mail->oauthClientId = "932857915584-eco8v9aejdb2n3mkltgvftf8e5h1eiko.apps.googleusercontent.com";
$mail->oauthClientSecret = "7SqFo7aPYvZ05cHlh5p3kMUD";
$mail->oauthRefreshToken = "1/4KJJ5XMyXqELMAhRXGYjz_I4SfoWfFR9N9RRA2VA2I0";

$mail->addAddress('jakabanasuy2@gmail.com');     // Add a recipient
$mail->isHTML(true);                               // Set email format to HTML
$mail->setFrom('from@example.com', 'Mailer');
$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

i don't have any idea, i've done search google but i dont find any solution. Before i ask in Can't Send PHPMailer with Oauth Google

Any solution for my case?

回答1:

For XOAUTH2 AuthType, if you are using the 5.2 version, you are instantiating the wrong class. The 6.0 also works different.

You should use:

$mail = new PHPMailerOAuth;

That is the reason of the following error:

2017-08-04 06:38:43 SERVER -> CLIENT: 250-smtp.gmail.com at your service, [180...... XOAUTH2 ...... SMTP Error: Could not authenticate.

Cheers!

A few things:

First, OAuth is really hard to debug anyway. I really recommend that you take a look at the 6.0 branch, in which the OAuth support is significantly improved. It comes with much better examples, and it would be very useful if you could help test it. This second step is key point and might solve your problem. There is slight difference in initiation( Use PHPMailerOAuth class), so please read the docs carefully.

Second, Go through this documentation, you might have followed it, but see if you are missing any step.

Third, Are you sure you got a refresh token and not a normal token?

Try these things and let me know, if it worked for you or not?
