6云图书管理系统-图书展示

1 /src/store中新增userInfo.js，用于保存用户的登录信息

import { defineStore } from "pinia"
import { ref } from 'vue'

export const userInfoStore = defineStore('userInfo', () => {
    //1.定义用户信息
    const info = ref({})
    const isAdmin = ref(false)
    //2.定义修改用户信息的方法
    const setInfo = (newInfo) => {
        info.value = newInfo
        isAdmin.value = newInfo.userRole === 'ADMIN'
    }
    //3.定义清空用户信息的方法
    const removeInfo = () => {
        info.value = {}
    }

    return { info, isAdmin, setInfo, removeInfo }
}, {
    persist: true
})

2 Login.vue组件登录成功之后，保存token

import { useTokenStore } from '@/stores/token.js'

const tokenStore = useTokenStore()
c
onst login = async () => {
    let result = await loginService(registerData.value)
    //保存token
    console.log("结果是" + result);
    tokenStore.setToken(result.data)
    //  保存用户登录信息
    ElMessage.success(result.msg ? result.msg : '登录成功')
    router.push('/')
}

3 /api/user.js中添加获取用户个人信息的接口

//获取用户信息
export const userInfoGetService = () => {
    return request.get('/user/userinfo');
}

4 首页LayoutVue.vue组件添加如下代码，用户登录成功之后，在首页获取用户信息，并根据是管理员还是普通用户，实现不同组件显示

// 导入ref
import { ref } from 'vue'
//导入接口函数
import { userInfoGetService } from '@/api/user.js'
//导入pinia
import { userInfoStore } from '@/stores/userInfo.js'
const useruserInfoStore = userInfoStore();
// 管理员状态
const isAdmin = ref(useruserInfoStore.isAdmin)

import { useTokenStore } from '@/stores/token.js'
const tokenStore = useTokenStore();
//获取个人信息
const getUserInf = async () => {
    let result = await userInfoGetService();
    //存储pinia
    useruserInfoStore.setInfo(result.data);
}
getUserInf()

5 首页LayoutVue完整代码如下

<script setup>
import {
    Management,
    Promotion,
    UserFilled,
    User,
    Crop,
    EditPen,
    SwitchButton,
    CaretBottom
} from '@element-plus/icons-vue'
import avatar from '@/assets/default.png'

// 导入ref
import { ref } from 'vue'
//导入接口函数
import { userInfoGetService } from '@/api/user.js'
//导入pinia
import { userInfoStore } from '@/stores/userInfo.js'
const useruserInfoStore = userInfoStore();


import { useTokenStore } from '@/stores/token.js'
const tokenStore = useTokenStore();

//获取个人信息
const getUserInf = async () => {
    let result = await userInfoGetService();
    //存储pinia
    useruserInfoStore.setInfo(result.data);
}
getUserInf()

// 管理员状态
const isAdmin = ref(useruserInfoStore.isAdmin.value)

// 导入路由
import router from '@/router'
import { ElMessage, ElMessageBox } from 'element-plus'
//条目被点击后，调用的函数
const handleCommand = (command) => {
    if (command == 'logout') {
        //退出登录
        ElMessageBox.confirm(
            '你确认退出登录码？',
            '温馨提示',
            {
                confirmButtonText: '确认',
                cancelButtonText: '取消',
                type: 'warning',
            }
        )
            .then(async () => {
                //用户点击了确认
                //清空pinia中的token和个人信息
                useruserInfoStore.setInfo('')
                tokenStore.token = ''
                //跳转到登录页
                router.push('/login')
            })
            .catch(() => {
                //用户点击了取消
                ElMessage({
                    type: 'info',
                    message: '取消退出',
                })
            })
    } else {
        router.push(`/user/${command}`);
    }
}

6 /api/books.js中添加图书查询接口

// 导入request.js请求工具
import request from '@/utils/request.js'

//图书列表
export const bookListService = () => {
    return request.get('/book/allBook')
}

7 后台Java处理代码

    //查询所有的图书
    @GetMapping("/allBook")
    public Result getAllBook(){
        System.out.println("收到查询请求");
        List<Book> bookList = iBookService.list();
        return Result.success(bookList);
    }

8 /books/BookResourcesVue.vue组件中添加如下代码

<script setup>
import { ref } from 'vue'
import { ElMessage } from 'element-plus'
import { Plus, Edit, Delete } from '@element-plus/icons-vue'

import { userInfoStore } from '@/stores/userInfo.js'
const useruserInfoStore = userInfoStore();
const isAdmin = ref(useruserInfoStore.isAdmin)

// 图书表单数据模型
const bookModel = ref({
    bookId: '',
    bookName: '',

    bookPress: '',
    bookAuthor: '',
    bookPagination: '',
    bookPrice: '',
    bookUploadtime: '',
    bookStatus: '',
    bookBorrower: '',
    bookBorrowtime: '',
    bookReturntime: ''
})

// 表单引用
const formRef = ref(null)

// 用户搜索时选中的状态
const state = ref('全部')


// 图书列表数据模型
const books = ref([

        "bookBorrower": "",
        "bookBorrowtime": "",
        "bookReturntime": ""
    },
    // 其他图书项...
])

// 表单验证规则
const rules = {

        { type: 'number', message: '页数必须是数字', trigger: 'blur' }
    ],
    bookPrice: [{ required: true, message: '请输入价格', trigger: 'blur' }]
}

// // 图书列表查询
import { bookListService, bookAddService } from '@/api/book.js'
const getBooks = async () => {
    let result = await bookListService()
    // 渲染列表数据
    books.value = result.data
}
getBooks()

// 控制抽屉是否显示
const visibleDrawer = ref(false)

// 导入 token
import { useTokenStore } from '@/stores/token.js'
const tokenStore = useTokenStore()


// 添加图书
const addBook = () => {
    console.log("借书功能");
}
// 写借阅图书的方法 borrowBook
const borrowBook = (bookId) => {
    console.log("借书功能");
}
