laravel的接值及验证

接值封装

第一种

//常见的
 [$province_id, $city_id, $school_id, $grade, $class, $name, $sex, $born] = postMore([['province_id', 0], ['city_id', 0], ['school_id', ''], ['grade', ''], ['class', 0], ['name', 0], ['sex', 1], ['born', 0]], $request, true);
$request->validate([
            'province_id' => ['required'],
            'city_id' => ['required'],
            'school_id' => ['required'],
            'grade' => ['required'],
            'class' => ['required'],
            'name' => ['required'],
            'sex' => ['required'],
            'born' => ['required'],
        ]);

第二种

//创建类
<?php

namespace App\Http\Requests\Login;

use Illuminate\Foundation\Http\FormRequest;

class LoginClassRequest extends FormRequest
{
    public function authorize()
    {
        return true;
    }

    public function rules()
    {
        return [
            'top_id' => 'integer|required|min:1',
        ];
    }

    public function messages()
    {
        return [
            'top_id.required' => 'top_id必须填写',
        ];
    }
}

随后注入到方法就ok了
运用的是依赖注入

  public function Massage(LoginClassRequest $request)
  {
  }
