Yii框架错误

1. yii\web\Request::cookieValidationKey must be configured with a secret key.

   解决办法到/config/web.php里面修改 'components' => [
           'request' => [
               // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
               'cookieValidationKey' =>'myYiifram',
           ],
