Yii2的邮件配置

'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
            ],

             ],  
        ],   
]

        $mail= Yii::$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
