How can I make an outbound HTTP POST request, with data, in node.js?
request is now deprecated. It is recommended you use an alternative
In no particular order and dreadfully incomplete:
native HTTP/S, const https = require('https');
node-fetch
axios
got
superagent
bent
make-fetch-happen
unfetch
tiny-json-http
needle
urllib

Some code examples
Original answer:
This gets a lot easier if you use the request library.
var request = require('request');
request.post(
'http://www.yoursite.com/formpage',
{ json: { key: 'value' } },
function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);
}
}
);
Aside from providing a nice syntax it makes json requests easy, handles oauth signing (for twitter, etc.), can do multi-part forms (e.g. for uploading files) and streaming.
To install request use command npm install request
Here's an example of using node.js to make a POST request to the Google Compiler API:
// We need this to build our post string
var querystring = require('querystring');
var http = require('http');
var fs = require('fs');
function PostCode(codestring) {
// Build the post string from an object
var post_data = querystring.stringify({
'compilation_level' : 'ADVANCED_OPTIMIZATIONS',
'output_format': 'json',
'output_info': 'compiled_code',
'warning_level' : 'QUIET',
'js_code' : codestring
});
// An object of options to indicate where to post to
var post_options = {
host: 'closure-compiler.appspot.com',
port: '80',
path: '/compile',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': Buffer.byteLength(post_data)
}
};
// Set up the request
var post_req = http.request(post_options, function(res) {
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('Response: ' + chunk);
});
});
// post the data
post_req.write(post_data);
post_req.end();
}
// This is an async file read
fs.readFile('LinkedList.js', 'utf-8', function (err, data) {
if (err) {
// If this were just a small part of the application, you would
// want to handle this differently, maybe throwing an exception
// for the caller to handle. Since the file is absolutely essential
// to the program's functionality, we're going to exit with a fatal
// error instead.
console.log("FATAL An error occurred trying to read in the file: " + err);
process.exit(-2);
}
// Make sure there's data before we post it
if(data) {
PostCode(data);
}
else {
console.log("No data to post");
process.exit(-1);
}
});
I've updated the code to show how to post data from a file, instead of the hardcoded string. It uses the async fs.readFile command to achieve this, posting the actual code after a successful read. If there's an error, it is thrown, and if there's no data the process exits with a negative value to indicate failure.
You can use request library. https://www.npmjs.com/package/request
var request = require('request');
To post JSON data:
var myJSONObject = { ... };
request({
url: "http://josiahchoi.com/myjson",
method: "POST",
json: true, // <--Very important!!!
body: myJSONObject
}, function (error, response, body){
console.log(response);
});
To post xml data:
var myXMLText = '<xml>...........</xml>'
request({
url: "http://josiahchoi.com/myjson",
method: "POST",
headers: {
"content-type": "application/xml", // <--Very important!!!
},
body: myXMLText
}, function (error, response, body){
console.log(response);
});
EDIT: As of February 2020 request has been deprecated.
Simple and dependency-free. Uses a Promise so that you can await the result. It returns the response body and does not check the response status code.
const https = require('https');
function httpsPost({body, ...options}) {
return new Promise((resolve,reject) => {
const req = https.request({
method: 'POST',
...options,
}, res => {
const chunks = [];
res.on('data', data => chunks.push(data))
res.on('end', () => {
let resBody = Buffer.concat(chunks);
switch(res.headers['content-type']) {
case 'application/json':
resBody = JSON.parse(resBody);
break;
}
resolve(resBody)
})
})
req.on('error',reject);
if(body) {
req.write(body);
}
req.end();
})
}
Usage:
async function main() {
const res = await httpsPost({
hostname: 'sentry.io',
path: `/api/0/organizations/org/releases/${changesetId}/deploys/`,
headers: {
'Authorization': `Bearer ${process.env.SENTRY_AUTH_TOKEN}`,
'Content-Type': 'application/json',
},
body: JSON.stringify({
environment: isLive ? 'production' : 'demo',
})
})
}
main().catch(err => {
console.log(err)
})
There are dozens of open-source libraries available that you can use to making an HTTP POST request in Node.
1. Axios (Recommended)
const axios = require('axios');
const data = {
name: 'John Doe',
job: 'Content Writer'
};
axios.post('https://reqres.in/api/users', data)
.then((res) => {
console.log(`Status: ${res.status}`);
console.log('Body: ', res.data);
}).catch((err) => {
console.error(err);
});
2. Needle
const needle = require('needle');
const data = {
name: 'John Doe',
job: 'Content Writer'
};
needle('post', 'https://reqres.in/api/users', data, {json: true})
.then((res) => {
console.log(`Status: ${res.statusCode}`);
console.log('Body: ', res.body);
}).catch((err) => {
console.error(err);
});
3. Request
const request = require('request');
const options = {
url: 'https://reqres.in/api/users',
json: true,
body: {
name: 'John Doe',
job: 'Content Writer'
}
};
request.post(options, (err, res, body) => {
if (err) {
return console.log(err);
}
console.log(`Status: ${res.statusCode}`);
console.log(body);
});
4. Native HTTPS Module
const https = require('https');
const data = JSON.stringify({
name: 'John Doe',
job: 'Content Writer'
});
const options = {
hostname: 'reqres.in',
path: '/api/users',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': data.length
}
};
const req = https.request(options, (res) => {
let data = '';
console.log('Status Code:', res.statusCode);
res.on('data', (chunk) => {
data += chunk;
});
res.on('end', () => {
console.log('Body: ', JSON.parse(data));
});
}).on("error", (err) => {
console.log("Error: ", err.message);
});
req.write(data);
req.end();
For details, check out this article.
I use Restler and Needle for production purposes.
They are both much more powerful than native httprequest. It is possible to request with basic authentication, special header entry or even upload/download files.
As for post/get operation, they also are much simpler to use than raw ajax calls using httprequest.
needle.post('https://my.app.com/endpoint', {foo:'bar'},
function(err, resp, body){
console.log(body);
});
Update 2020:
I've been really enjoying phin - The ultra-lightweight Node.js HTTP client
It can be used in two different ways. One with Promises (Async/Await) and the other with traditional callback styles.
Install via: npm i phin
Straight from it's README with await:
const p = require('phin')
await p({
url: 'https://ethanent.me',
method: 'POST',
data: {
hey: 'hi'
}
})
Unpromisifed (callback) style:
const p = require('phin').unpromisified
p('https://ethanent.me', (err, res) => {
if (!err) console.log(res.body)
})
As of 2015 there are now a wide variety of different libraries that can accomplish this with minimal coding. I much prefer elegant light weight libraries for HTTP requests unless you absolutely need control of the low level HTTP stuff.
One such library is Unirest
To install it, use npm.
$ npm install unirest
And onto the Hello, World! example that everyone is accustomed to.
var unirest = require('unirest');
unirest.post('http://example.com/helloworld')
.header('Accept', 'application/json')
.send({ "Hello": "World!" })
.end(function (response) {
console.log(response.body);
});
Extra:
A lot of people are also suggesting the use of request [ 2 ]
It should be worth noting that behind the scenes Unirest uses the request library.
Unirest provides methods for accessing the request object directly.
Example:
var Request = unirest.get('http://mockbin.com/request');
You can also use Requestify, a really cool and simple HTTP client I wrote for nodeJS + it supports caching.
Just do the following:
var requestify = require('requestify');
requestify.post('http://example.com', {
hello: 'world'
})
.then(function(response) {
// Get the response body (JSON parsed or jQuery object for XMLs)
response.getBody();
});
var https = require('https');
/**
* HOW TO Make an HTTP Call - POST
*/
// do a POST request
// create the JSON object
jsonObject = JSON.stringify({
"message" : "The web of things is approaching, let do some tests to be ready!",
"name" : "Test message posted with node.js",
"caption" : "Some tests with node.js",
"link" : "http://www.youscada.com",
"description" : "this is a description",
"picture" : "http://youscada.com/wp-content/uploads/2012/05/logo2.png",
"actions" : [ {
"name" : "youSCADA",
"link" : "http://www.youscada.com"
} ]
});
// prepare the header
var postheaders = {
'Content-Type' : 'application/json',
'Content-Length' : Buffer.byteLength(jsonObject, 'utf8')
};
// the post options
var optionspost = {
host : 'graph.facebook.com',
port : 443,
path : '/youscada/feed?access_token=your_api_key',
method : 'POST',
headers : postheaders
};
console.info('Options prepared:');
console.info(optionspost);
console.info('Do the POST call');
// do the POST call
var reqPost = https.request(optionspost, function(res) {
console.log("statusCode: ", res.statusCode);
// uncomment it for header details
// console.log("headers: ", res.headers);
res.on('data', function(d) {
console.info('POST result:\n');
process.stdout.write(d);
console.info('\n\nPOST completed');
});
});
// write the json data
reqPost.write(jsonObject);
reqPost.end();
reqPost.on('error', function(e) {
console.error(e);
});
This is the simplest way I use to make request: using 'request' module.
Command to install 'request' module :
$ npm install request
Example code:
var request = require('request')
var options = {
method: 'post',
body: postData, // Javascript object
json: true, // Use,If you are sending JSON data
url: url,
headers: {
// Specify headers, If any
}
}
request(options, function (err, res, body) {
if (err) {
console.log('Error :', err)
return
}
console.log(' Body :', body)
});
You can also use Node.js's built-in 'http' module to make request.
I like the simplicity of superagent (https://github.com/visionmedia/superagent). Same API on both node and browser.
;(async function() {
var response = await superagent.post('http://127.0.0.1:8125/', {age: 2})
console.log(response)
})
There is also node-fetch (https://www.npmjs.com/package/node-fetch), which has an API that matches fetch from the browsers - however this requires manual query string encoding, does not automatically handle content types, or so any of the other work superagent does.
In Node.js 18
Fetch
The fetch() method in JavaScript is used to request data from a
server. The request can be of any type of API that returns the data in
JSON or XML.
Say goodbye to the node-fetch package ,axios and request ,... now the fetch API is available on the global scope by default.
app.get('/', (req, res, next) => {
// Make a post Request.
fetch('https://jsonplaceholder.typicode.com/posts', {
method: 'POST',
body: JSON.stringify({
title: 'foo',
body: 'bar',
userId: 1,
}),
headers: {
'Content-type': 'application/json; charset=UTF-8',
},
})
.then((response) => response.json())
.then((json) => console.log(json))
.catch(error => {
console.log(error)
})
res.send('Fetch API is available on the global scope by default')
})
We can make requests as we do in browsers.
For More Information
If you are looking for promise based HTTP requests, axios does its job nicely.
const axios = require('axios');
axios.post('/user', {firstName: 'Fred',lastName: 'Flintstone'})
.then((response) => console.log(response))
.catch((error) => console.log(error));
OR
await axios.post('/user', {firstName: 'Fred',lastName: 'Flintstone'})
To Post Rest/JSON Request
We can simply use request package and save the values we have to send in Json variable.
First install the require package in your console by
npm install request --save
var request = require('request');
var options={
'key':'28',
'key1':'value',
'key2':'value'
}
request({
url:"http://dev.api.ean.com/ean-services/rs/hotel/v3/ping?
minorRev="+options.key+
"&cid="+options.key1+
"&apiKey="+options.key2,
method:"POST",
json:true},function(error,response,body){
console.log(body)
}
);
This my solution for POST and GET.
About the Post method:
If the body is a JSON object, so it's important to deserialize it with JSON.stringify and possibly set the Content-Lenght header accordingly:
var bodyString=JSON.stringify(body)
var _headers = {
'Content-Length': Buffer.byteLength(bodyString)
};
before writing it to the request:
request.write( bodyString );
About both Get and Post methods:
The timeout can occur as a socket disconnect, so you must register its handler like:
request.on('socket', function (socket) {
socket.setTimeout( self.timeout );
socket.on('timeout', function() {
request.abort();
if(timeout) return timeout( new Error('request timed out') );
});
});
while the request handler is
request.on('timeout', function () {
// Timeout happend. Server received request, but not handled it
// (i.e. doesn't send any response or it took to long).
// You don't know what happend.
// It will emit 'error' message as well (with ECONNRESET code).
req.abort();
if(timeout) return timeout( new Error('request timed out') );
});
I strongly suggest to register both the handlers.
The response body is chunked, so you must concat chunks at the data handler:
var body = '';
response.on('data', function(d) {
body += d;
});
At the end the body will contain the whole response body:
response.on('end', function() {
try {
var jsonResponse=JSON.parse(body);
if(success) return success( jsonResponse );
} catch(ex) { // bad json
if(error) return error(ex.toString());
}
});
It is safe to wrap with a try...catchtheJSON.parse` since you cannot be sure that it is a well-formatted json actually and there is no way to be sure of it at the time you do the request.

I found a video which explains on how to achieve this: https://www.youtube.com/watch?v=nuw48-u3Yrg
It uses default "http" module together with "querystring" and "stringbuilder" modules. The application takes two numbers (using two textboxes) from a web page and upon submit, returns sum of those two (along with persisting the values in the textboxes). This is the best example I could find anywhere else.
var http = require("http");
var qs = require("querystring");
var StringBuilder = require("stringbuilder");
var port = 9000;
function getCalcHtml(req, resp, data) {
var sb = new StringBuilder({ newline: "\r\n" });
sb.appendLine("<html>");
sb.appendLine(" <body>");
sb.appendLine(" <form method='post'>");
sb.appendLine(" <table>");
sb.appendLine(" <tr>");
sb.appendLine(" <td>Enter First No: </td>");
if (data && data.txtFirstNo) {
sb.appendLine(" <td><input type='text' id='txtFirstNo' name='txtFirstNo' value='{0}'/></td>", data.txtFirstNo);
}
else {

sb.appendLine(" </tr>");
}

resp.end();

After struggling a lot while creating a low level utility to handle the post and get requests for my project, I decided to post my effort here. Much on the lines of accepted answer, here is a snippet for making http and https POST requests for sending JSON data.
const http = require("http")

Axios is a promise based HTTP client for the browser and Node.js. Axios makes it easy to send asynchronous HTTP requests to REST endpoints and perform CRUD operations. It can be used in plain JavaScript or with a library such as Vue or React.
const axios = require('axios');
var dataToPost = {
email: "your email",
password: "your password"
};
let axiosConfiguration = {
headers: {
'Content-Type': 'application/json;charset=UTF-8',
"Access-Control-Allow-Origin": "*",
}
};
axios.post('endpoint or url', dataToPost, axiosConfiguration)
.then((res) => {
console.log("Response: ", res);
})
.catch((err) => {
console.log("error: ", err);
})
let request = require('request');
let jsonObj = {};
request({
url: "https://myapii.com/sendJsonData",
method: "POST",
json: true,
body: jsonObj
}, function (error, resp, body){
console.log(resp);
});
Or you could use this library:
let axios = require("axios");
let jsonObj = {};
const myJsonAPI = axios.create({
baseURL: 'https://myapii.com',
timeout: 120*1000
});
let response = await myJsonAPI.post("sendJsonData",jsonobj).catch(e=>{
res.json(e);
});
console.log(response);
Posting another axios example of an axios.post request that uses additional configuration options and custom headers.
var postData = {
email: "test#test.com",
password: "password"
};
let axiosConfig = {
headers: {
'Content-Type': 'application/json;charset=UTF-8',
"Access-Control-Allow-Origin": "*",
}
};
axios.post('http://<host>:<port>/<path>', postData, axiosConfig)
.then((res) => {
console.log("RESPONSE RECEIVED: ", res);
})
.catch((err) => {
console.log("AXIOS ERROR: ", err);
})
By using request dependency.
Simple solution :
import request from 'request'
var data = {
"host":"127.1.1.1",
"port":9008
}
request.post( baseUrl + '/peers/connect',
{
json: data, // your payload data placed here
headers: {
'X-Api-Key': 'dajzmj6gfuzmbfnhamsbuxivc', // if authentication needed
'Content-Type': 'application/json'
}
}, function (error, response, body) {
if (error) {
callback(error, null)
} else {
callback(error, response.body)
}
});
Request-Promise Provides promise based response.
http response codes other than 2xx will cause the promise to be rejected. This can be overwritten by setting options.simple = false
var options = {
method: 'POST',
uri: 'http://api.posttestserver.com/post',
body: {
some: 'payload'
},
json: true // Automatically stringifies the body to JSON
};
rp(options)
.then(function (parsedBody) {
// POST succeeded...
})
.catch(function (err) {
// POST failed...
});
In case you need an XML request I'll share my codes with axios library.
const {default: axios} = require('axios');
let xmlString = '<XML>...</XML>';
axios.post('yourURL', xmlString)
.then((res) => {
console.log("Status: ", res.status);
console.log("Body: ", res.data);
})
.catch((err) => {
console.error("Error: ", err);
});
Make arbitrary HTTP requests with the Node.js http library.
Don't use third-party packages that don't provide any new functionality.
Use the Node.js built-ins.
https://nodejs.org/api/http.html#httprequesturl-options-callback
The example from the documentation for http.request shows you how to make a "hello world" POST request.
Here is the example. Ask questions in the comments, e.g., if you are learning Node.js and want more resources.
const http = require('node:http');
const postData = JSON.stringify({
'msg': 'Hello World!',
});
const options = {
hostname: 'www.google.com',
port: 80,
path: '/upload',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': Buffer.byteLength(postData),
},
};
const req = http.request(options, (res) => {
console.log(`STATUS: ${res.statusCode}`);
console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
res.setEncoding('utf8');
res.on('data', (chunk) => {
console.log(`BODY: ${chunk}`);
});
res.on('end', () => {
console.log('No more data in response.');
});
});
req.on('error', (e) => {
console.error(`problem with request: ${e.message}`);
});
// Write data to request body
req.write(postData);
req.end();
