Query String

Query String#

This module provides utilities for dealing with query strings. It provides the following methods:

querystring.stringify(obj[, sep][, eq][, options])#

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

Options object may contain encodeURIComponent property (querystring.escape by default), it can be used to encode string with non-utf8 encoding if necessary.

Example:

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

querystring.stringify({foo: 'bar', baz: 'qux'}, ';', ':')
// returns
'foo:bar;baz:qux'

// Suppose gbkEncodeURIComponent function already exists,
// it can encode string with `gbk` encoding
querystring.stringify({ w: '中文', foo: 'bar' }, null, null,
  { encodeURIComponent: gbkEncodeURIComponent })
// returns
'w=%D6%D0%CE%C4&foo=bar'

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' }

querystring.urlencode(str)#

Escapes special characters in a url

querystring.urlencode('https://github.com/luvit/luvit/blob/master/deps/querystring.lua')

Returns

'https%3A%2F%2Fgithub%2Ecom%2Fluvit%2Fluvit%2Fblob%2Fmaster%2Fdeps%2Fquerystring%2Elua'

querystring.urldecode(str)#

Un-escapes special characters in a url

querystring.urldecode('https%3A%2F%2Fgithub%2Ecom%2Fluvit%2Fluvit%2Fblob%2Fmaster%2Fdeps%2Fquerystring%2Elua')
