1、在app下创建目录文件：Libraries/Rules.php

    1. <?php
    2. namespace app\Validator;
    3. class Rules
    4. {
    5.     const STUDENT = [
    6.         // 添加
    7.         'create'    => [
    8.             'name'      => 'required|between:2,10',
    9.             'mobile'    => 'required|regex:/^1[3|4|5|7|8][0-9]{9}$/i',
    10.             'email'     => 'email',
    11.             'birth'     => 'required|date_format:Y-m-d H:i:s',
    12.             'sex'       => 'required|in:0,1,2,3',
    13.             'address'   => 'between:5,50',
    14.             'remark'    => 'between:2,10',
    15.         ]
    16.     ];
    17. }

    2、 在composer.json中的autoload/classmap中添加类所在位置：”app/Libraries”
    3、执行命令使之生效
