# request 사용법
var request = require("request");
request.get('/books', function(error, response, body) {
});
request.post('/books', { body: { key: value } }, function(error, response, body) {
});
request.put('/books', { body: { key: value } }, function(error, response, body) {
});
request.delete('/books', function(error, response, body) {
});
app.post('/send', function(req, res) {
var message = {
sender: req.body.sender,
ko: req.body.ko,
en: req.body.en
};
console.log(message);
messages.push(message);
res.status(200).send({ message: "Success" });
});
