I'm getting this SMTP error when using the newest PHPMailer release:
SMTP Error: Could not authenticate.
I've tried using SSL instead of TLS with port number 465. OpenSSL is already loaded in the config file, and I've looked through the troubleshooting guide none of this has made a difference, what exactly is wrong with my code? One thing I'm not sure of is including the OAuth2 provider class with this :
use League\OAuth2\Client\Provider\Google;
There's no file path for that, should I change this? Also, when I change encryption to $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS; and now I get this : SMTP ERROR: Failed to connect to server: (0).
Here's the code:
class gmail_xoauth
{
public static function sendMail($subject,$body,$address)
{
$mail = new PHPMailer();
$mail->isSMTP();
$mail->SMTPDebug = SMTP::DEBUG_CLIENT;
$mail->Host = 'smtp.gmail.com';
$mail->Port = 587;
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->SMTPAuth = true;
$mail->AuthType = 'XOAUTH2';
//Fill in authentication details here
//Either the gmail account owner, or the user that gave consent
$email = 'myemail@gmail.com';
$clientId = 'clientid';
$clientSecret = 'clientSecret';
//Obtained by configuring and running get_oauth_token.php
//after setting up an app in Google Developer Console.
$refreshToken = 'refreshToken';
//Create a new OAuth2 provider instance
$provider = new Google(
[
'clientId' => $clientId,
'clientSecret' => $clientSecret,
]
);
//Pass the OAuth provider instance to PHPMailer
$mail->setOAuth(
new OAuth(
[
'provider' => $provider,
'clientId' => $clientId,
'clientSecret' => $clientSecret,
'refreshToken' => $refreshToken,
'username' => $email,
]
)
);
//Set who the message is to be sent from
//For gmail, this generally needs to be the same as the user you logged in as
$mail->setFrom($email, 'me');
//Set who the message is to be sent to
$mail->addAddress($address, 'John Doe');
//Set the subject line
$mail->Subject = $subject;
//Read an HTML message body from an external file, convert referenced images to embedded,
//convert HTML into a basic plain-text alternative body
$mail->CharSet = PHPMailer::CHARSET_UTF8;
$mail->msgHTML(file_get_contents('PHPMailer/PHPMailer-master/examples/contentsutf8.html'), __DIR__);
//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';
//Attach an image file
$mail->addAttachment('PHPMailer/PHPMailer-master/examples/images/phpmailer_mini.png');
//send the message, check for errors
if (!$mail->send()) {
echo 'Mailer Error: '. $mail->ErrorInfo;
} else {
echo 'Message sent!';
}
}
}
