先上图：

整个角色管理是如何做的吗？

首先你要处理后端，要先把角色存到用户那。

这是用户管理部分的内容：

可以看到一个用户是有多个角色的。

看到没有，存的是数组

数组的是一个 role 对象

role 对象是这样：

主要是存一个 name 就好。permissions 是权限列表。

import { Request, Response } from 'express';
import Role from '../models/role';
import handleAsync from '../utils/handleAsync';// Build query based on query parameters
const buildQuery = (queryParams: any): any => {const query: any = {};if (queryParams.name) {query.name = { $regex: queryParams.name, $options: 'i' };}return query;
};// 获取所有角色
const getRoles = handleAsync(async (req: Request, res: Response) => {const { current = '1', pageSize = '10' } = req.query;const query = buildQuery(req.query);const roles = await Role.find(query).populate('permissions').sort('-createdAt') // Sort by creation time in descending order.skip((+current - 1) * +pageSize).limit(+pageSize).exec();res.json({success: true,data: roles,});
});// 根据 ID 获取角色
const getRoleById = handleAsync(async (req: Request, res: Response) => {const role = await Role.findById(req.params.id).exec();if (!role) {res.status(404);throw new Error('Role not found');}res.json({success: true,data: role,});
});// 添加新角色
const addRole = handleAsync(async (req: Request, res: Response) => {const newRole = new Role({...req.body,});const savedRole = await newRole.save();res.json({success: true,data: savedRole,});
});// 更新角色
const updateRole = handleAsync(async (req: Request, res: Response) => {const { id } = req.params;const updatedRole = await Role.findByIdAndUpdate(id,{ ...req.body },{ new: true },).exec();if (!updatedRole) {res.status(404);throw new Error('Role not found');}res.json({success: true,data: updatedRole,});
});// 删除角色
const deleteRole = handleAsync(async (req: Request, res: Response) => {const { id } = req.params;const role = await Role.findByIdAndDelete(id).exec();if (!role) {res.status(404);throw new Error('Role not found');}res.json({success: true,data: { message: 'Role deleted successfully' },});
});// 批量删除角色
const deleteMultipleRoles = handleAsync(async (req: Request, res: Response) => {const { ids } = req.body;await Role.deleteMany({_id: { $in: ids },}).exec();res.json({success: true,message: `${ids.length} roles deleted successfully`,});
});export {getRoles,getRoleById,addRole,updateRole,deleteRole,deleteMultipleRoles,
};

这是后端代码，就是增删改查。比较容易理解。
