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>
