Make a HTTP request in your Controller - sails.js

Is it possible to make a request in the controller? I have tried using the node.js http module but didn't have any succes. Is there any other method to do this?

For people coming from the future, request package has fully deprecated since Feb 11th, 2020.

The alternative choices that request has recommended can be found as following.

Ok, I managed to solve this using another module 'request'. What I did:

Install the module in your project:

npm install -S request

And in you code you should have: 

var request = require('request');

request.get({
  url: <your url>
}, function(error, response, body) {
  if (error) {
    sails.log.error(error);
  }
  else {
    sails.log.info(response);
    sails.log.info(body);
  }
});

I wrap node's native https.get (or http.get) in a promise and call from controller like so:

const https = require('https')

// wrap node's https.get stream call as a promise
// note: assumes utf-8 encoded data payload to get.
async function getdata(url) {
  return new Promise((resolve, reject) => {
    https.get(url, (res) => {
      res.setEncoding('utf8');
      let data = '';
      res.on('data', (chunk) => {
        data = data + chunk;
      });
      res.on('end', () => {
        resolve(data);
      })
    }).on('error', (e) => {
      reject(e);
    });
  });
}


// Call from sails controller
module.exports = {
  myaction: async function(req, res) {
    let data;
    try {
      data = await getdata('https://example.com/index.html');
    } catch (e) {
      // handle it
    }    
  ...
  }
}
