thinkphp5.1控制器自定义参数获取及场景验证

thinkphp5.1控制器自定义参数获取及场景验证，通过post方法获取参数，循环赋值，把需要验证的参数放到数组中进行字段校验

控制器方法新增更新

<?php
namespace app\api\controller;

use think\Controller;
use app\common\model\Coupon as Coupons;

class Coupon extends Controller
{
    /*
     * 新增优惠券
    */
    public function create()
    {
        $optionParams = ['name', 'price','sub_name','order_limit_price','s_time','e_time','num','num_limit','coupon_price','type','mark'];
        $params = [];

        if (!empty($this->request->post())) {
            foreach ($this->request->post() as $key => $value) {
                if (in_array($key, $optionParams) && !empty($value)) {
                    $params[$key] = $value;
                } else {
                    $params[$key] = '';
                }
            }
        } else {
            $this->result([], 0, '参数不能为空', 'json');
        }

        $resValidate = $this->validate($params, 'app\api\validate\Coupon.add');

        if ($resValidate !== true){
            $this->result([], 1, $resValidate, 'json');
        }

        $result = (new Coupons())->insert($this->request->post());

        if ($result) {
            $this->result([], 0, '新增成功', 'json');
        } else {
            $this->result([], 1, '新增失败', 'json');
        }
    }

    /*
     * 更新优惠券
    */
    public function update()
    {
        $optionParams = ['id','name', 'price','sub_name','order_limit_price','s_time','e_time','num','num_limit','coupon_price','type','mark'];
        $params = [];

        if (!empty($this->request->post())) {
            foreach ($this->request->post() as $key => $value) {
                if (in_array($key, $optionParams) && !empty($value)) {
                    $params[$key] = $value;
                } else {
                    $params[$key] = '';
                }
            }
        } else {
            $this->result([], 0, '参数不能为空', 'json');
        }

        $resValidate = $this->validate($params, 'app\api\validate\Coupon.edit');

        if ($resValidate !== true){
            $this->result([], 1, $resValidate, 'json');
        }

        $result = (new Coupons())->updateCoupon($this->request->post());

        if ($result) {
            $this->result([], 0, '更新成功', 'json');
        } else {
            $this->result([], 1, '更新失败', 'json');
        }
    }

}
