Laravel添加验证场景提高针对性质的验证

laravel没有场景验证的概念，是一个验证类验证一个函数，验证数据不是很方便，封装补足一下

封装添加场景的方法

<?php
    
    namespace App\Http\Requests;
    
    use Illuminate\Foundation\Http\FormRequest;
    use Illuminate\Support\Str;
    use Illuminate\Http\Exceptions\HttpResponseException;
    use Illuminate\Contracts\Validation\Validator;
    
    /**
     * 使用方法：
     * Class AbstractRequest
     * @package App\Http\Requests
     */
    class BaseRequest extends FormRequest
    {
        public $scenes = [];
        public $currentScene;               //当前场景
        public $autoValidate = false;       //是否注入之后自动验证
    
        public function authorize()
        {
            return true;
        }
    
        /**
         * 设置场景
         * @param $scene
         * @return $this
         */
        public function scene($scene)
        {
            $this->currentScene = $scene;
            return $this;
        }
    
    
    
        /**
         * 覆盖自动验证方法
         */
        public function validateResolved()
        {
            if ($this->autoValidate) {
                $this->handleValidate();
            }
        }
    
        /**
         * 验证方法
         * @param string $scene
         * @throws \Illuminate\Auth\Access\AuthorizationException
         * @throws \Illuminate\Validation\ValidationException
         */
        public function validate($scene = '')
        {
            if ($scene) {
                $this->currentScene = $scene;
            }
            $this->handleValidate();
        }
    
        /**
         * 根据场景获取规则
         * @return array|mixed
         */
        public function getRules()
        {
            $rules = $this->container->call([$this, 'rules']);
            $newRules = [];
            if ($this->currentScene && isset($this->scenes[$this->currentScene])) {
                $sceneFields = is_array($this->scenes[$this->currentScene])
                    ? $this->scenes[$this->currentScene] : explode(',', $this->scenes[$this->currentScene]);
                foreach ($sceneFields as $field) {
                    if (array_key_exists($field, $rules)) {
                        $newRules[$field] = $rules[$field];
                    }
                }
                return $newRules;
            }
            return $rules;
        }
    
        /**
         * 覆盖设置 自定义验证器
         * @param $factory
         * @return mixed
         */
        public function validator($factory)
        {
            return $factory->make(
                $this->validationData(), $this->getRules(),
                $this->messages(), $this->attributes()
            );
        }
    
        /**
         * 最终验证方法
         * @throws \Illuminate\Auth\Access\AuthorizationException
         * @throws \Illuminate\Validation\ValidationException
         */
        protected function handleValidate()
        {
            $instance = $this->getValidatorInstance();
            if ($instance->fails()) {
                $this->failedValidation($instance);
            }
            $this->passedValidation();
        }
        /**
         * 重写报错部分-适应API JSON下发的需求
         */
        protected function failedValidation(Validator $validator)
        {
            $error= $validator->errors()->all();
            throw new HttpResponseException(response()->json(['code'=>505,'msg'=>$error['0'],'data'=>[]]));
        }
    
    }

验证类的使用

<?php
    
    namespace App\Http\Requests;
    
    
    class MsgBoardRequest extends BaseRequest
    {
    
    
    
        /**
         * Get the validation rules that apply to the request.
         *
         * @return array
         */
        public function rules()
        {
            return [
                'id'=>'required',
                'title' => 'required|max:10',
                'content' => 'required|max:255',
            ];
        }
        /**
         * 获取已定义验证规则的错误消息
         *
         * @return array
         */
        public function messages()
        {
            return [
                'id.required'=>'ID不能为空',
                'title.max' =>'标题太长了，简化一下吧',
                'title.required'  => '标题不能为空',
                'content.max' => '内容太多了',
                'content.required'  => '内容不能为空',
            ];
        }
        public $scenes = [
            'addMsg' => ['title', 'content'],
            'deleteMsg' =>['id']
        ];
    }

控制器中进行调用

public function addMsg(MsgBoardRequest $request){
    	$request->validate('addMsg');
    }
    public function deleteMsg(MsgBoardRequest $request){
        $request->validate('deleteMsg');
    }
