在 Yii 2.0 上,对某些没有绑定任何模型类的值进行临时验证(利用核心验证器)的实现
1、打印出当前模型
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | api\modules\v1\models\PlanTask Object ( [_attributes:yii\db\BaseActiveRecord:private] => Array ( [id] => 3 [group_id] => 015ce30b116ce86058fa6ab4fea4ac63 [config_column_id] => 1 [plan_id] => 1 [sort_order] => 1 [title] => 无线成都1 [config_task_id] => 1 [create_user_id] => 8 [create_name] => 13281105967 [exec_user_id] => 185 [exec_name] => test1 [place] => 地点 [task_info] => <p>选题摘要</p> [task_data] => a:0:{} [ended_at] => 1530695128 [current_step_id] => 18 [prev_status] => 2 [status] => 1 [created_at] => 1528103128 [updated_at] => 1528188754 ) ] ) |
2、现在有请求参数,tool,必填,工具标识,jove:Jove微编;nova:Nova精编,且验证范围([jove, nova]);
3、由于tool不存在于模型 api\modules\v1\models\PlanTask 中,因此需要执行临时验证,代码如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | use yii\base\DynamicModel; class VideoEditAction extends Action { const TOOL_JOVE = 'jove' ; //工具:Jove微编 const TOOL_NOVA = 'nova' ; //工具:Nova精编 // 临时验证 $request = Yii:: $app ->request; $tool = $request ->get( 'tool' ); $dynamicModel = new DynamicModel(compact( 'tool' )); $dynamicModel ->addRule( 'tool' , 'required' ) ->addRule( 'tool' , 'in' , [ 'range' => [self::TOOL_JOVE, self::TOOL_NOVA]]) ->validate(); if ( $dynamicModel ->hasErrors()) { $response = Yii:: $app ->getResponse(); $response ->setStatusCode(422, 'Data Validation Failed.' ); foreach ( $dynamicModel ->getFirstErrors() as $message ) { $firstErrors = $message ; break ; } return [ 'code' => 20004, 'message' => Yii::t( 'error' , Yii::t( 'error' , Yii::t( 'error' , '20004' ), [ 'firstErrors' => $firstErrors ]))]; } } |
4、在 Postman 中测试,当不填写 tool 参数时,符合预期,如图1
1 2 3 4 | { "code": 20004, "message": "数据验证失败:Tool不能为空。" } |
5、在 Postman 中测试,当 tool 参数不等于([jove, nova])时,符合预期,如图2
1 2 3 4 | { "code": 20004, "message": "数据验证失败:Tool是无效的。" } |
