六、服务端代码

  1. let express = require('express');
  2. let bodyParser = require('body-parser');
  3. let fs = require('fs');
  5. let slides = require('./database/sliders');
  6. let bookData = './database/book.json';

七、vue.config.js

  1. module.exports = {
  2.   outputDir: '../book-server/static',
  3.   devServer: {
  4.     open: true,
  5.     proxy: {
  6.       '/api': {
  7.         target: 'http://localhost:8090',
  8.         changeOrigin: true,
  9.         secure: false
  10.       }
  11.     }
  12.   }
  13. };
