A lib to deal with URL encode / decode things.
npm install liburl"urllib" is a very good lib to deal with things about URL. I wrote this lib just like urllib's style.
More detail information please see https://docs.python.org/2/library/urllib.html
``js
var liburl = require('liburl');
liburl.quote('/!connolly/'); // /%21connolly/
`
`js
var liburl = require('liburl');
liburl.quote_plus('/!connolly go/'); // %2F%21connolly+go%2F
`
`js
var liburl = require('liburl');
liburl.unquote('/%21connolly/'); // /!connolly/
`
`js
var liburl = require('liburl');
liburl.quote_plus('%2F%21connolly+go%2F'); // /!connolly go/
