Nodejs: url.parse issue with arrays inside query

问题

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?

回答1:

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'] }

This module does parsing as required:

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

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