querystring.parse()

querystring.parse(str[, sep][, eq][, options])

Deserialize a query string to an object. Optionally override the default separator ('&') and assignment ('=') characters.

Options object may contain maxKeys property (equal to 1000 by default), it'll be used to limit processed keys. Set it to 0 to remove key count limitation.

Options object may contain decodeURIComponent property (querystring.unescape by default), it can be used to decode a non-utf8 encoding string if necessary.

Example:

querystring.parse('foo=bar&baz=qux&baz=quux&corge')
// returns { foo: 'bar', baz: ['qux', 'quux'], corge: '' }

// Suppose gbkDecodeURIComponent function already exists,
// it can decode `gbk` encoding string
querystring.parse('w=%D6%D0%CE%C4&foo=bar', null, null,
  { decodeURIComponent: gbkDecodeURIComponent })
// returns { w: '中文', foo: 'bar' }
