/**
* 开启 {@link Rest} 功能后,将会有 `this.params` 对象
* @member {Object} Context#params
* @example
* ##### ctx.params.id {String}
*
* 资源 id如 `GET /api/users/1` => `'1'`
*
* ##### ctx.params.ids {Array<String>}
*
* 一组资源 id如 `GET /api/users/1,2,3` => `['1', '2', '3']`
*
* ##### ctx.params.fields {Array<String>}
*
* 期待返回的资源字段,如 `GET /api/users/1?fields=name,title` => `['name', 'title']`.
* 即使应用 Controller 实现返回了全部字段,[REST] 处理器会根据 `fields` 筛选只需要的字段。
*
* ##### ctx.params.data {Object}
*
* 请求数据对象
*
* ##### ctx.params.page {Number}
*
* 分页码,如 `GET /api/users?page=10` => `10`
*
* ##### ctx.params.per_page {Number}
*
* 每页资源数目,如 `GET /api/users?per_page=20` => `20`
