  • 图书管理系统前端

    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
        },
    

    srcviewsooksBooks.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>
