Nodejs: url.parse issue with arrays inside query

Question

http://domain.com/action?params[]=1&params[]=2&params[]=3

returns:

query: { 'params[]': [ '1', '2', '3' ] }

params[] as name instead of params?

After PHP it's kinda surprise.

jQuery serialization is adding [] on parameters btw.

Are you guys wrote a helper for this or I'm just doing it wrong?

This seems like expected behavior to me; I would be more surprised if the querystring parser removed part of the name. That is, the module is doing exactly what I would expect from a parser which simply splits name/value pairs by '&' and name/value by '=' (and unescapes special characters).

var qs = require('querystring');

qs.parse('params=1&params=2&params=3'); // Name should be "params"
// => { 'params': ['1', '2', '3'] }

qs.parse('params[]=1&params[]=2&params[]=3'); // Name should be "params[]"
// => { 'params[]': ['1', '2', '3'] }

Mate i'm using jQuery and params serialization is taken by it. It's sending this params[]=1&params[]=2&params[]=3 type of query.

I have found a module for this. Question is closed. :)

A little observation is that, naturally, if you pass only one parameter using params=1 it will not be parsed as an array.

This module does parsing as required:

https://github.com/visionmedia/node-querystring

There is another one for complex arrays if this doesn't work:

https://github.com/jazzychad/querystring.node.js

Both found here: https://github.com/joyent/node/wiki/modules

Yes indeed. The default Node.js decided not to implement the feature for params with multiple values, but TJ's module solves that.

Guess Ry shouldn't be bothered with such misc issues atm.

Yeah probably it's ok to leave this out of the core and into a separate module.
