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
