config.php配置

mailer' => [
    'class' => 'yii\swiftmailer\Mailer',
    'useFileTransport' => false,//false傳送郵件，true只是生成郵件在runtime資料夾下，不發郵件
    'transport' => [
        'class' => 'Swift_SmtpTransport',
        'host' => 'smtp.exmail.qq.com',  //每種郵箱的host配置不一樣
        'username' => '
 
[email protected]',
        'password' => 'swrtesz5563^',
        'port' => '25',
        'encryption' => 'tls',

    ],
    'messageConfig'=>[
        'charset'=>'UTF-8',
        'from'=>['[email protected]'=>'admin']
    ],
],

使用

$mail = Yii::$app->mailer->compose();
$mail->setTo('
 
[email protected]');
$mail->setSubject("郵件測試");
//$mail->setTextBody('zheshisha ');   //釋出純文字文字
$mail->setHtmlBody("<br>問我我我我我");    //釋出可以帶html標籤的文字
//$mail->attach($content)  //帶附件
if($mail->send())
    echo "success";
else
    echo "failse";
die();
