'components' => [
  'mailer' => [
            'class' => 'yii\swiftmailer\Mailer',
            'useFileTransport' =>false,//这句一定有，false发送邮件，true只是生成邮件在runtime文件夹下，不发邮件
            'transport' => [
                'class' => 'Swift_SmtpTransport',
                'host' => 'smtp.163.com',  //每种邮箱的host配置不一样
                'username' => '-qq32853803-@163.com',
                'password' => '.......',   邮箱授权码 而非密码
                'port' => '25',
                'encryption' => 'tls', // tls  ssl
            ],
            'messageConfig'=>[
                'charset'=>'UTF-8',
                'from'=>['qq328538031@163.com'=>'admin']
             ],
        ],
]

        $mail= Yii::$app->mailer->compose();
        $mail->setTo('cgjs@163.com');
        $mail->setSubject("邮件测试");
        //$mail->setTextBody('zheshisha ');   //发布纯文字文本
        $mail->setHtmlBody("<br>问我我我我我");    //发布可以带html标签的文本
//        print_R($mail);
//        print_r($mail->send());
        if($mail->send())
