vue如何实现接通后端api以及部署到服务器的方法

dev: {
  // Paths
  assetsSubDirectory: 'static',
  assetsPublicPath: '/',
  proxyTable: {
   '/api':{
    target: 'http://www.baidu.com',//后端api地址
    changeOrigin: true,
    pathRewrite:{
     '^api': ''
    }
   }
  },

export default {
 name: 'App',
 created: function () {
  
  this.$http.defaults.baseURL = 'https://www.baidu.com/api'
  //后端api默认前缀，每个请求都加上这个前缀访问后台api
  
 }
}

'use strict'
module.exports = {
 NODE_ENV: '"production"',
 API_HOST: '"http://www.baidu.com"'//后端api地址
}

'use strict'
const merge = require('webpack-merge')
const prodEnv = require('./prod.env')
 
module.exports = merge(prodEnv, {
 NODE_ENV: '"development"',
 API_HOST: '"http://localhost:8080"'//这里是本地的访问ip配置
})

export const apiAddress = {
  install(Vue){
    Vue.prototype.$javaAddress = '11';
  }
};
export const config = {
  install(Vue){
    Vue.prototype.$config = '1';
  }
};
export default { apiAddress, config };

import { apiAddress, config } from './config/address';
Vue.use(apiAddress);
Vue.use(config);

export default {
  install(Vue){
    Vue.prototype.$javaAddress = '111';
  }
};
import address from './config/address';
Vue.use(address);
