Access rest api using nodejs - node.js

Question

I am trying to access opencorporates.com and using their REST API.
I got this code from How to make remote REST call inside Node.js? any CURL?. But it is not fetching any data. I tried wget on the url and it worked perfectly fine.
app.js
var https = require('http');
var optionsget = {
host : 'opencorporates.com',
port : 8080,
path : '/v0.2/companies/search?q=barclays+bank&jurisdiction_code=gb',
method : 'GET'
};
console.info('Options prepared:');
console.info(optionsget);
console.info('Do the GET call');
var reqGET = https.get(optionsget, function(res) {
console.log("statusCode: ", res.statusCode);
console.log("headers: ", res.headers);
res.on('data', function(d) {
console.info('GET result:\n');
process.stdout.write(d);
console.info('\n\nCall completed');
});
});
reqGet.end();
reqGet.on('error', function(e) {
console.error(e);
});

Answer 1

Because Node runs asynchronously, the returned data is broken into chunks.
The .on('data') event returns a portion of the data, which you then need to stitch/append back to a variable. You can then capture the complete output with .on('end').
See this example for more info: Why is node.js breaking incoming data into chunks? (#vossad01's answer)
That said, #SilviuBurcea's suggestion to use request is a much simpler way of handling http requests so you don't have to write and handle all of this yourself.

Answer 2

Try using request module. https://github.com/mikeal/request It's the http module on steroids.

Answer 3

Tried running the code locally, and first there is a capitalization error
var reqGET = https.get(optionsget, function(res) {
reqGet.end();
Second, the web address was not working at the address, nor with secure
var optionsget = {
host : 'api.opencorporates.com',
port : 80,
path : '/v0.2/companies/search?q=barclays+bank&jurisdiction_code=gb',
method : 'GET'
};
Its worth noting that if you wanted to actually use https, you would need to change the require line
var https = require('https');

This is fully functional version for your reference:
var http = require('http');
var optionsget = {
host : 'api.opencorporates.com',
port : 80,
path : '/v0.2/companies/search?q=barclays+bank&jurisdiction_code=gb',
method : 'GET'
};
console.info('Options prepared:');
console.info(optionsget);
console.info('Do the GET call');
var reqGet = http.get(optionsget, function(res) {
console.log("statusCode: ", res.statusCode);
console.log("headers: ", res.headers);
buffer='';
res.on('data', function(d) {
//console.info('GET result:\n');
//process.stdout.write(d);
buffer += d.toString();
//console.info('\n\nCall completed');
});
res.on('end', function() {
console.info('GET result:\n');
console.log(buffer);
console.info('\n\nCall completed');
});
});
reqGet.on('error', function(e) {
console.error(e);
});
reqGet.end();
