There are two servers, how to send a request from the second server to the first server:

const http = require('http');
    http.createServer((req, res)=>{
      
    }).listen(1337);

const http = require("http");
const request = http.request({
    'host': 'localhost',
    'port': 1337,
    'path': '/',
    'method': 'POST'
});

request.on('response', function (res) {
    res.on('data', function(data){
        console.log(data);
    });
})
request.end();
