Yii2 发送邮件

1. 主要使用swiftmailer,但由于Yii2.0会自带所以不用安装，只需配置下就可以了
2. 接下来就是配置了 在components中进行如下配置，其中的SMTP密码需要在你自己的邮箱里去获取

'components' => [
//邮箱发送配置
'mailer' => [ 
         'class' => 'yii\swiftmailer\Mailer', 
         'viewPath' => '@common/mail', 
         'useFileTransport' => false, 
         'transport' => [ 
             'class' => 'Swift_SmtpTransport', 
             'host' => 'smtp.qq.com', 
             'username' => '[email protected]',//发送者邮箱地址
             'password' => 'tqxbygmfhpimbefa', //SMTP密码
             'port' => '25', 
             'encryption' => 'tls', 
         ], 
         'messageConfig'=>[ 
             'charset'=>'UTF-8', 
             'from'=>['[email protected]'=>'system'] 
         ], 
     ],
     /.....
 ]
