Question

How can we make a HTTP request like this in NodeJS? Example or module appreciated.

  -H 'Content-Type: application/json' \
  -d '{"longUrl": "http://www.google.com/"}'

Axios is Lesser and Better:

const data = JSON.stringify({
  message: 'Hello World!'
})

const url = "https://localhost/WeatherAPI";

axios({
    method: 'POST',
    url, 
    data: JSON.stringify(data), 
    headers:{'Content-Type': 'application/json; charset=utf-8'}
}) 
  .then((res) => {
    console.log(`statusCode: ${res.status}`)
    console.log(res)
  })
  .catch((error) => {
    console.error(error)
  })

Mikeal's request module can do this easily:

var request = require('request');

var options = {
  uri: 'https://www.googleapis.com/urlshortener/v1/url',
  method: 'POST',
  json: {
    "longUrl": "http://www.google.com/"
  }
};

request(options, function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body.id) // Print the shortened url.
  }
});

Thank you for this helpful answer. In the end I realize the option is well documented. But lost in the middle of plenty others... – Physical

It didn't worked for me until i added the headers: {'content-type' : 'application/json'}, option. – Sidecar

- the NodeJs 'request' module is deprecated. - how would we do this using 'http' module ? Thank you. – Barozzi

Simple Example

var request = require('request');

//Custom Header pass
var headersOpt = {  
    "content-type": "application/json",
};
request(
        {
        method:'post',
        url:'https://www.googleapis.com/urlshortener/v1/url', 
        form: {name:'hello',age:25}, 
        headers: headersOpt,
        json: true,
    }, function (error, response, body) {  
        //Print the Response
        console.log(body);  
});

As the official documentation says:

body - entity body for PATCH, POST and PUT requests. Must be a Buffer, String or ReadStream. If json is true, then body must be a JSON-serializable object.

When sending JSON you just have to put it in body of the option.

var options = {
    uri: 'https://myurl.com',
    method: 'POST',
    json: true,
    body: {'my_date' : 'json'}
}
request(options, myCallback)

For some reason only this worked for me today. All other variants ended up in bad json error from API.

Besides, yet another variant for creating required POST request with JSON payload.

request.post({
    uri: 'https://www.googleapis.com/urlshortener/v1/url',
    headers: {'Content-Type': 'application/json'},
    body: JSON.stringify({"longUrl": "http://www.google.com/"})
});

Answer 6

Since the request module that other answers use has been deprecated, may I suggest switching to node-fetch:

const fetch = require("node-fetch")

const url = "https://www.googleapis.com/urlshortener/v1/url"
const payload = { longUrl: "http://www.google.com/" }

const res = await fetch(url, {
  method: "post",
  body: JSON.stringify(payload),
  headers: { "Content-Type": "application/json" },
})

const { id } = await res.json()

Using request with headers and post.

var options = {
            headers: {
                  'Authorization': 'AccessKey ' + token,
                  'Content-Type' : 'application/json'
            },
            uri: 'https://myurl.com/param' + value',
            method: 'POST',
            json: {'key':'value'}
 };
      
 request(options, function (err, httpResponse, body) {
    if (err){
         console.log("Hubo un error", JSON.stringify(err));
    }
    //res.status(200).send("Correcto" + JSON.stringify(body));
 })
