headers)
export const addBook = (params, headers) => post("/books/book/", params, headers)
export const editBook = (params, headers) => put("/books/book/", params, headers)
export const delBook = (params, headers) => del("/books/book/", params, headers)

1.2 router/index.js 添加路由

import Books from '@/views/books/Books'
export default new Router({
routes: [
{ path: '/', name: 'Books', component: Books }, // 图书增删改查
案例
]
})

// 删除
del(index) {

import Vue from 'vue'
import App from './App'
import router from './router'
Vue.config.productionTip = false
// 使用 elementui
// npm i element-ui -S 安装到当前项目
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
Vue.use(ElementUI)
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
components: { App },
template: '<App/>'
