How to make an HTTP POST request in node.js?

Question

How can I make an outbound HTTP POST request, with data, in node.js?

Answer 1

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);
});

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);
});

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(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

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 can you another 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: "[e-mail]",
  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);
})

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();
    });
