//获取验证参数

        $model = \yii\base\DynamicModel::validateData([

            'activity_code' => Yii::$app->getRequest()->post('activity_code'),

            'uid' => Yii::$app->getRequest()->post('uid'),

            'username' => Yii::$app->getRequest()->post('username'),

            'phone' => Yii::$app->getRequest()->post('phone'),
