本文實例講述了Yii2使用swiftmailer發送郵件的方法。分享給大家供大家參考，具體如下：
'mail' => [ 'class' => 'yii/swiftmailer/Mailer', 'viewPath' => '@backend/mail', 'useFileTransport' => false,//set this property to false to send mails to real email addresses //comment the following array to send mail using php's mail function 'transport' => [ 'class' => 'Swift_SmtpTransport', 'host' => 'smtp.gmail.com', 'username' => 'username@gmail.com', 'password' => 'password', 'port' => '587', 'encryption' => 'tls', ], ],],
控制器：
Yii::$app->mail->compose('your_view', ['params' => $params]) ->setFrom([/Yii::$app->params['supportEmail'] => 'Test Mail']) ->setTo('to_email@xx.com') ->setSubject('This is a test mail ' ) ->send();
