How to receive image file to api server(Node.js) - node.js

Question

I want to build api server by node.js.
and I want to post image file to my api server.
I was able to write GET method logic in my code
but, I have no idea write POST method logic.
plase help me
↓my code (node.js)
// preprocessing
// import library
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var fs = require('fs');
// post setting
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
// port setting
var port = process.env.PORT || 3000;
// express setting
var router = express.Router();
router.use(function(req, res, next) {
console.log('Something is happening.');
next();
});
// main
// GET method
router.get('/', function(req, res) {
res.json({ message: 'Hello World' });
});
// POST method
router.route('/image')
.post(function(req1, res1) {
res1.json({image : req1.body});
});
// routing
app.use('/api/v1', router);
// start server
app.listen(port);
console.log('listen on port ' + port);
↓ tes curl command(GET)
curl -k -x GET "http://XXX/api/v1"
↓ curl result(GET)
"message" :"Hello World"
↓ test curl command(POST)
curl -k -X POST -F "images_file=#test01.jpg" "http://XXXX/api/v1/image"
↓ curl result(POST)
"image" :""

Answer 1

client side
<form action="/pictures/upload" method="POST" enctype="multipart/form-data">
Select an image to upload:
<input type="file" name="image">
<input type="submit" value="Upload Image">
</form>
server side use multer package and write post route as following
var express = require('express')
, router = express.Router()
, multer = require('multer')
var uploading = multer({
dest: __dirname + '../public/uploads/',
})
router.post('/upload', uploading, function(req, res) {
})
module.exports = router
