NodeJS POST Request body string doesn't match

I have a server.js in my Droplet(server), I have a POST method here, I'm trying to check if the coming string matches with a spesific string.

server.js

const http = require('http')

const server = http.createServer(function(request, response) {

    var body = '';

    if (request.method === 'POST') {


        request.on('data', function (data) {
            body = data;
        })

        if (body.includes("token") === true){
            request.on('end', function () {

                response.writeHead(200,body);
                response.write(body);
                response.end('success');
            });

        }

        if (body.includes("token") === false){
            request.on('end', function () {

                response.writeHead(200);
                response.write(body);
                response.end('Not Auth. ')
            });
        }


}})

server.listen(3000)

And here is the file I sent requests.

request.js

const axios = require('axios')

axios
    .post('SERVERIP', "token"
    )
    .then(res => {
        console.log(`statusCode: ${res.statusCode}`)
        console.log(res.data)
    })
    .catch(error => {
        console.error(error)
    })

The problem is, it always goes to the second IF statement, I can see the incoming string in second IF statement (the part response.write) and it always matches in the first one "token". I did even check the types of the strings, but somehow it always goes to the second IF statement.

Am I missing something here? Why it doesn't match the string even though the strings are the same and the first IF statement doesn't work?

You need to place your body.includes checks inside your request.on callback. JavaScript is asynchronous, so your callback will be executed aftyer your if statements are evaluated.
