图书管理系统前端

标签:model   order   key   button   outer   发布   methods   请求   初始   

在http/apis.js/添加后端请求路由

/* eslint-disable */
import { head } from ‘shelljs‘
import{get,post,put,del} from ‘./index‘


//用户登录
export const login = (params, headers) => post("/login/", params, headers)

//书籍管理接口
export const getBookList=(params,headers)=>get("/book/",params,headers)
export const addBook=(params,headers)=>post("/book/",params,headers)
export const editBook=(params,headers)=>put(‘/book/‘,params,headers)
export const delBook = (params, headers) => del("/book/", params, headers)

router/index.js 添加路由

import Books from ‘@/views/books/Books‘
 //图书增删改查案例
    {
      path: ‘/books‘,
      name: ‘Books‘,
      component: Books
    },

src\views\books\Books.vue 这里是父组件

<template>
	<div>
		<h1>图书管理系统</h1>
		<div style="margin: 30px;">
			<button @click="addNew">新增图书</button>
			<BookEdit
				v-show=‘dialogVisible‘
				:visible.sync=‘dialogVisible‘
				:data=‘editData‘
				@save=‘save‘
			></BookEdit>
		</div>
		<div>
			<table style=‘margin: auto; border: solid 1px black;‘>
				<tr>
					<th>图书编号</th>
					<th>图书名字</th>
					<th>出版时间</th>
					<th>阅读数</th>
					<th>评论数</th>
					<th>操作</th>
					</tr>
				<tr v-for="(book, index) in books" :key="book.id">

<style>
table tr td {

src\views\books\BookEdit.vue 子组件

<template>
