yii2 sends email (configuring QQ version)

1.在配置文件里面配置

'mailer' => [  
           'class' => 'yii\<strong>Swift</strong>mailer\Mailer', //服务器类

            'useFileTransport' =>false,//这句一定有，false<strong>发送邮件</strong>，true只是生成邮件在runtime文件夹下，不<strong>发邮件</strong></span>	   
           'transport' => [  
              'class' => '<strong>Swift</strong>_SmtpTransport', //使用的类
              'host' => 'smtp.qq.com', //邮箱服务一地址
              'username' => '1806001025@qq.com',//邮箱地址，发送的邮箱  
              'password' => '***********',  //自己填写邮箱密码
              'port' => '465',  //服务器端口
              'encryption' => 'ssl', //加密方式 
			  ],
		'messageConfig'=>[  
                 'charset'=>'UTF-8', //编码 
                 'from'=>['1806001025@qq.com'=>'admin']  //邮件里面显示的邮件地址和名称
                ],  
 ]

        $fff = Yii::$app->mailer->compose()
		        ->setFrom(['1806001025@qq.com'=>'我看你傻了']) //和上面的from字段相对应  可以只写一个
                        ->setTo('429281869@qq.com')
                       ->setSubject('dsfsfsddddddddddddddddddddddddddd')
                       ->setTextBody('sdfffffffffffffffffffffffffffff')
                       ->send();
