3)test.js  (백엔드 서버 : Node.js  )

node.js로 CORS 방식 허용하기로

# http, express, cors 모듈 설치 후

npm install http express cors

 

 

 

test.js

const express = require('express');
require('express-async-errors');

const app = express();
const cors = require('cors');
app.use(cors());


//인증 처리 미들웨어
app.use(require('../middlewares/verifyToken'));


//const router = express.Router();

/* GET users listing. */
//router.get('/', function (req, res, next) {
  //res.send('respond with a resource  test');
  //res.render("test", { student_id: 'tes1t' });
//});


app.post('/', async (req, res, next) => {  
  res.send("post ok : ");
});


app.get('/', (req, res, next) => {
  res.send("get ok  : " + req.params.id);
});

app.get('/:id', (req, res, next) => {  
  res.send("get ok  - " + req.params.id);
});


app.put('/:id', (req, res, next) => {
  res.send("put ok  - " + req.params.id);
});


app.delete('/:id', (req, res, next) => {
  res.send("delete ok  - " + req.params.id);
});


//에러 처리 미들웨어
app.use(require('../middlewares/error'));

module.exports = app;

 

middlewares/verifyToken.js

module.exports=(req, res, next) => {  
  //console.log(JSON.stringify(req.headers))
  console.log(req.headers);
  console.log("인증 처리hear");  
  next();
};
