This file lets you make post request to any server running https or http with nodejs. You can modify the code send json data. Thank me later.

get_POST_data.js

const https = require('https');
const http = require('http');
const querystring = require('querystring');
const url = require('url');

let get_POST_data = function(urlToPost, formData, headersToSend) {
    return new Promise(function(resolve, reject) {
        let parsed_url = url.parse(urlToPost);
        let post_data = querystring.stringify(formData);
        let secure = false;
        if (parsed_url.protocol === 'https:') {
            secure = true;
        }
        headersToSend["Content-Length"] = post_data.length;
        headersToSend["Host"] = parsed_url.hostname;
        headersToSend["Origin"] = parsed_url.protocol + '//' + parsed_url.hostname;
        headersToSend["Referer"] = parsed_url.protocol + '//' + parsed_url.hostname;
        let options = {
            host: parsed_url.hostname,
            port: parsed_url.port,
            path: parsed_url.path,
            method: 'POST',
            headers: headersToSend
        }
        let protocol = http;
        if (secure) {
            options.rejectUnauthorized = false;
            protocol = https;
        }
        let cbresponse = "";
        let request = protocol.request(options, (response) => {
            response.setEncoding('utf8');
            response.on('data', function(chunk) {
                cbresponse = cbresponse + chunk;
            });
        });
        request.on('error', (e) => {
            reject(e);
        });
        request.on('close', () => {
            resolve(cbresponse);
        });
        request.write(post_data);

        request.end();

    });
