[nodejs] POST 데이터 받기 express 사용 / 미사용 비교

1. http/ querystring만 사용

1. var http = require('http')
2. ,qs = require('querystring');
3. http.createServer(function (req, res) {
4. if( req.url == '/' && req.method == 'POST'){
5. var postBody = '';
6. req.on('data', function (data) {
7. postBody += data;
8. });
9. req.on('end', function () {
10. var post = qs.parse(postBody);
11. //post데이터확인
12. console.log(post['postname']);
13. });
14. res.end('true');
15. }else{
16. res.writeHead(404, {'Content-Type': 'text/plain'});
17. res.end('404 ERROR');
18. }
19. }).listen(8001);

2. http / express  / body-parser 사용

1. var express = require('express')
2. ,http = require('http')
3. ,bodyParser = require('body-parser');
4. var app = express();
5. app.use(bodyParser.urlencoded({extended: true}));
6. //app.use(bodyParser.json());
7. app.post("/", function( req, res){
8. res.writeHead(200,{"Content-Type" : "text/plain"});
9. //post데이터확인
10. console.log(req.param('postname',null));
11. res.end('test');
12. });
13. app.use(function( req, res){
14. res.writeHead(404,{"Content-Type" : "text/plain"});
15. res.end('404 ERROR');
16. });
17. http.createServer(app).listen(8001);
