How is the data received from the form?

Question

Node.js

Hello! I came across a series of articles: Easy Node Authentication: Setup and Local . I can not understand how the data is received from the form?

Answer 1

If the data goes by the GET method, then the data is received from the address bar, if POST, then requestan event is hung on the object Like datathis

http.createServer(function (req, res) {
 if (req.method == "POST" && req.url == "example") {
 req.on("data", function (chunk) {
 // и здесь все парсится
})
}
}).listen(3000)

and express does it all for you, and stores the data transmitted by the POST method in a property, bodyi.e. req.body
