餐厅系统分为前台和后台两个部分：
- 前台是用户点菜页面，无需登录即可点菜，但必须在url里带上“店铺id”和“桌号id”，不然会报404错误。
- 后台是店家管理页面，必须登录才能操作，主要有 店铺管理、用户管理、菜品管理、菜品分类、订单管理、生成二维码 等6大模块。(The restaurant system is divided into two parts: front desk and backstage.

- the front desk is the user to order the page, no need to log in, but you have to bring "shop ID" and "table number ID" in the URL, otherwise it will report 404 errors.

The backstage is the store management page, which must be logged in to operate. There are 6 main modules: store management, user management, dish management, dish classification, order management, and two-dimensional code generation.)
