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

If the array need to be received as it is, you can set useQuerystring as true:

UPDATE: list key in the following code example has been changed to 'list[]', so that OP's ruby backend can successfully parse the array.

Here is example code:

const request = require('request');

let data = {
  'name': 'John',
  'list[]': ['XXX', 'YYY', 'ZZZ']
};

request({
  url: 'https://requestb.in/1fg1v0i1',
  qs: data,
  useQuerystring: true
}, function(err, res, body) {
  // ...
});

In this way, when the HTTP GET request is sent, the query parameters would be:

?name=John&list[]=XXX&list[]=YYY&list[]=ZZZ

and the list field would be parsed as ['XXX', 'YYY', 'ZZZ']

Without useQuerystring (default value as false), the query parameters would be:

?name=John&list[][0]=XXX&list[][1]=YYY&list[][2]=ZZZ
