零基础快速开发Vue图书管理系统—权限管理篇（六）

一、引入角色管理体系

二、设置角色并同步到数据库

const mongoose = require('mongoose');
const  getMeta, preSave  = require('../Schemas/helpers')

const CharacterSchema = new mongoose.Schema(
    name: String,
    title: String,
    power: Object,

    meta: getMeta(),
);
CharacterSchema.pre('save', preSave);

mongoose.model('Character', CharacterSchema);

const mongoose = require('mongoose');

const  connect  = require('../src/db/index');
const character = require('../src/helpers/character');

const  defaultCharacters  = character;
const Character = mongoose.model('Character');

connect()
    .then(async() => 
        console.log('开始初始化角色集合');
        await Character.insertMany(defaultCharacters);
        console.log('角色集合初始化完成');


    )

const defaultCharacters = [
    title: '管理员',
    name: 'admin',
    power: 
        book: [0],
        user: [0],
    ,
, 
    title: '成员',
    name: 'member',
    power: 
        book: [1],
        user: [-1],

    ,
, ];

module.exports = 
    defaultCharacters,

三、角色列表获取接口实现

const Router = require('@koa/router');
const mongoose = require('mongoose');
// const  getBody  = require('../../helpers/utils')
const  v4: uuidv4  = require('uuid');


const Character = mongoose.model('Character');
const router = new Router(
    prefix: '/character',
);
router.get('/list', async(ctx) => 
    const list = await Character.find().exec();
    ctx.body = 
        data: list,
        code: 1,
        msg: '获取列表成功'
    
)

module.exports = router;

四、获取角色列表并放在Vuex中

import  createStore  from "vuex";
import  character  from "@/service";
import  result  from "../helpers/utils";
export default createStore(
    state: 
        characterInfo: ,
    ,
    mutations: 
        setCharacterInfo(state, characterInfo) 
            state.characterInfo = characterInfo;
        
    ,
    actions: 
        async getCharacterInfo(store) 
            const res = await character.list();
            result(res)
                .success(( data ) => 
                    store.commit('setCharacterInfo', data)
                )

        
    ,

);

五、支持添加用户的时候可以设置角色

router.post('/add', async(ctx) => 
    const 
        account,
        password,
        character,
     = ctx.request.body;
    const char = Character.findOne(
        _id: character,
    );
    if (!char) 
        ctx.body = 
            msg: '出错啦',
            code: 0,
        ;
        return;
    
    const user = new User(
        account,
        password: password || '123123',
        character,
    )

    const res = await user.save()

    ctx.body = 
        data: res,
        code: 1,
        msg: '添加成功'
    ;
);
