Node.js - Array is converted to object when sent in HTTP GET request query

Question

The following Node.js code:

var request = require(\'request\');

var getLibs = function() {
    var options = { packages: [\'example1\', \'example2\', \'example3         


        

Answer 1

This problem can be solved using Request library itself. Request internally uses qs.stringify. You can pass q option to request which it will use to parse array params.

You don't need to append to url which leaves reader in question why that would have been done.

Reference: https://github.com/request/request#requestoptions-callback

const options = {
  method: 'GET',
  uri: 'http://localhost:3000/package',
  qs: {
    packages: ['example1', 'example2', 'example3'], 
    os: 'linux', 
    pack_type: 'npm' 
  },
  qsStringifyOptions: {
    arrayFormat: 'repeat' // You could use one of indices|brackets|repeat
  },
  json: true
};
