Laravel combinado con el marco de la base de datos Medoo para implementar la interfaz de consulta de paginación

Código de implementación

public function pageApi(Request $request)
    {
        $page = $request->post('page', 1);
        $pageSize = $request->post('page_size', 10);

        $param = $request->post();

        $where = [];
        $where['is_delete'] = 0;

        if (!empty($param['username'])) {
            $where['username[~]'] = $param['username'];
        }

        if (!empty($param['status']) && in_array($param['status'], [1, 2])) {
            $where['status'] = $param['status'];
        }

        if (isset($param['admin']) && in_array($param['admin'], [0, 1])) {
            $where['admin'] = $param['admin'];
        }

        $total = $this->medoo->count('user', 'id', $where);
        if ($total == 0) {
            return ['total' => 0, 'data' => []];
        }

        $where['LIMIT'] = [($page - 1) * $pageSize, $pageSize];
        $where['ORDER'] = ['id' => 'DESC'];

        $data = $this->medoo->select('user', ['id','username', 'password', 'head_url', 'status'], $where);

        return ['total' => $total, 'data' => $data];
    }

Estructura de la tabla de la base de datos

CREATE TABLE `api_user` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(20) NOT NULL,
  `password` varchar(50) NOT NULL,
  `head_url` char(150) NOT NULL COMMENT '头像',
  `admin` tinyint(4) NOT NULL DEFAULT '0',
  `time` int(11) unsigned NOT NULL,
  `is_delete` tinyint(3) unsigned NOT NULL DEFAULT '0' COMMENT '0：未删除，1：已删除',
  `status` tinyint(3) unsigned NOT NULL DEFAULT '1' COMMENT '状态   1：启用， 2：禁用',
  PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=34 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;
