图书管理页面

1.图书管理页面

1.1 http/apis.js 添加后端请求路由

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

// 图书管理接口
export const getBookList = (params, headers) => get("/books/book/", params, 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 Vue from 'vue'
import Router from 'vue-router'

import Books from '@/views/books/Books'

Vue.use(Router)

export default new Router({
  mode: 'history',
  routes: [ 
    { path: '/books', name: 'Books', component: Books },
  ]
})

1.5 src/mian.js 引入ElementUI

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
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/>'
})
