Nodejs+Vue 前后端连接 dist 包,express开篇写法和Vue 通过用HBuilder X 工具生成(Vue项目 打包)

前端:

打开 

运行 npm run build 得到 dist 文件夹

后端 Express 喜欢的写法

index.js

注这个就是接包dist目录的:

app.use(express.static('dist'))

// dist 是项目的打包资源路径,一般为根目录下dist

const express = require('express') //require函数引入express包
const app = express() //调用函数
// const routes = require('./routes/index');  //引入路由模块
const fs = require('fs');
// const path = require('path');
const hostname = 'localhost';
const port = 3000;

//实现静态资源服务
// app.use(express.static('./')) //public就是静态资源的根目录,静态资源放于此文件夹
app.use(express.static('dist')) // dist 是项目的打包资源路径,一般为根目录下dist
 
 //中间件
 app.use((req,resp,next) => {
     //中文乱码处理
     resp.header('Content-Type','text/html;charset=utf-8');
     next();
 });
 app.use((req,resp,next) => {
     //跨域设置
     resp.header("Access-Control-Allow-Credentials", true);
     resp.header("Access-Control-Allow-Origin", "*");
     resp.header("Access-Control-Allow-Headers", "X-Requested-With");
     resp.header("Access-Control-Allow-Methods", "PUT,POST,GET,DELETE,OPTIONS");
     resp.header("X-Powered-By", ' 3.2.1');
     resp.header("Content-Type", "application/json;charset=utf-8");
     next();
 });
 const path = require('path');

 
 app.engine('html', require('express-art-template'));
 //添加解析参数模块,能够解析POST方式提交的参数
 const bodyParser = require('body-parser');
 app.use(bodyParser.urlencoded({extended:true}));
  app.use(bodyParser.json());
  
app.get('/list', function (req, res) {
   fs.readFile( __dirname + "/" + "./db/sdata.json", 'utf8', function (err, data) {
       // console.log( data );
       res.end( data );
   });
})
 // app.use(routes); //挂载路由到app服务中
 
app.listen(3000, () => { //创建监听
	console.log(`server is running at http://${hostname}:${port}/`);
    console.log('服务器启动成功...')
})

配置文件 package.json 复制下来 ,运行 npm i 或npm install

{
  "name": "vue-test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "node index.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.20.2",
    "express": "^4.18.2",
    "express-art-template": "^1.0.1"
  }
}

再运行Node.js Express

命令:npm start

Vue项目 打包 后也可用:

npm i serve (npm install -g serve)

serve dist (运行打包dist目录)

React 项目 打包:

yarn build (打包React项目)

serve build (运行打包build目录) 或 express 里 app.use(express.static('build'))
