Ich weiß, dass dies eine alte Frage ist, aber sie ist immer noch aktiv und alle Antworten, die ich gesehen habe, zeigten die einfache Authentifizierung, die veraltet ist. Hier ist ein Beispiel, das zeigt, wie man E-Mails mit SMTP über Googles Gmail-Server mit PHPMailer und XOAUTH2-Authentifizierung versendet:
//Import PHPMailer classes into the global namespace
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\OAuth;
//Alias the League Google OAuth2 provider class
use League\OAuth2\Client\Provider\Google;
//SMTP needs accurate times, and the PHP time zone MUST be set
//This should be done in your php.ini, but this is how to do it if you don't have access to that
date_default_timezone_set('Etc/UTC');
//Load dependencies from composer
//If this causes an error, run 'composer install'
require '../vendor/autoload.php';
//Create a new PHPMailer instance
$mail = new PHPMailer();
//Tell PHPMailer to use SMTP
$mail->isSMTP();
//Enable SMTP debugging
//SMTP::DEBUG_OFF = off (for production use)
//SMTP::DEBUG_CLIENT = client messages
//SMTP::DEBUG_SERVER = client and server messages
$mail->SMTPDebug = SMTP::DEBUG_SERVER;
//Set the hostname of the mail server
$mail->Host = 'smtp.gmail.com';
//Set the SMTP port number:
// - 465 for SMTP with implicit TLS, a.k.a. RFC8314 SMTPS or
// - 587 for SMTP+STARTTLS
$mail->Port = 465;
//Set the encryption mechanism to use:
// - SMTPS (implicit TLS on port 465) or
// - STARTTLS (explicit TLS on port 587)
$mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;
//Whether to use SMTP authentication
$mail->SMTPAuth = true;
//Set AuthType to use XOAUTH2
$mail->AuthType = 'XOAUTH2';
//Fill in authentication details here
//Either the gmail account owner, or the user that gave consent
$email = 'someone@gmail.com';
$clientId = 'RANDOMCHARS-----duv1n2.apps.googleusercontent.com';
$clientSecret = 'RANDOMCHARS-----lGyjPcRtvP';
//Obtained by configuring and running get_oauth_token.php
//after setting up an app in Google Developer Console.
$refreshToken = 'RANDOMCHARS-----DWxgOvPT003r-yFUV49TQYag7_Aod7y0';
//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, 'First Last');
//Set who the message is to be sent to
$mail->addAddress('someone@gmail.com', 'John Doe');
//Set the subject line
$mail->Subject = 'PHPMailer GMail XOAUTH2 SMTP test';
//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('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
$mail->addAttachment('images/phpmailer_mini.png');
//send the message, check for errors
if (!$mail->send()) {
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message sent!';
}
