lumen6：在Controller.php中简单验证封装

1。首先use

use Validator;

2。写封装好的方法

    public function validateInput($rules, $requests)
    {
        $validator = Validator::make($requests, $rules);

        if ($validator->fails()) {
            return $this->responseData('', 406, $validator->messages()->first());
        } else {
            $this->validated = array_intersect_key($requests, $rules);//比较一下键名是否一致
            $this->validated = $requests;
            return false;
        }
    }

3。使用

 public function visitSign(Request $request)
    {
        //第二步：接受值，判断类型；入库；返回参数值
        $requests = $request->all();
        $rules = [
            'address' => 'bail|nullable|string',//unique:school,name
            'longitude' => 'bail|nullable|numeric',
            'latitude' => 'bail|nullable|numeric',
            'method' => 'bail|required|string'
        ];
        if ($error = $this->validateInput($rules, $requests)) {
            return $error;
        }
        $req = $this->validated;
        $method = $req['method'];
        if (!in_array($method, config('cate.method'))) {
            return $this->responseData('', 406, '拜访方式不存在');
        }

     }
