Description

Implements a data type for constructing and destructing x-www-urlencoded strings. See http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.1

Synopsis

Representation of a URL-encoded string

data URLEncoded Source

A container for URLEncoded data

Instances

Eq URLEncoded
Show URLEncoded
Monoid URLEncoded
URLShow URLEncoded
URLEncode URLEncoded
AddURLEncoded URLEncoded

filter :: ((String, String) -> Bool) -> URLEncoded -> URLEncoded Source

Create a URLEncoded object that represents all pairs from the input that match the supplied predicate

class URLShow a whereSource

Serialize a value into a String for encoding as part of an x-www-urlencoded value

Methods

urlShow :: a -> String Source

Instances

URLShow Bool
URLShow Char
URLShow Int
URLShow Integer
URLShow URI
URLShow URLEncoded
URLShow [Char]

class URLEncode a whereSource

Encode a value as x-www-urlencoded

Methods

urlEncode :: a -> URLEncoded Source

Instances

URLEncode URLEncoded
URLEncode a => URLEncode (Maybe a)
(URLShow a, URLShow b) => URLEncode (a, b)

Generate

empty :: URLEncoded Source

URLEncoded data with no pairs

importString :: MonadError e m => String -> m URLEncoded Source

Parse this string as x-www-urlencoded

importList :: [(String, String)] -> URLEncoded Source

Import this list of pairs as URLEncoded data

importURI :: MonadError e m => URI -> m URLEncoded Source

(%=) :: (URLShow a, URLShow b) => a -> b -> URLEncoded Source

Create singleton URLEncoded data containing the supplied key and value

(%=?)Source

Arguments

:: (URLShow a, URLShow b)
=> a	key
-> Maybe b	value
-> URLEncoded

If the second value is Nothing, return empty URLEncoded data. Otherwise return singleton URLEncoded data that contains the given key and value.

(%&) :: (URLEncode q1, URLEncode q2) => q1 -> q2 -> URLEncoded Source

class AddURLEncoded a whereSource

Methods

(%?) :: URLEncode args => a -> args -> aSource

Instances

AddURLEncoded URI
AddURLEncoded URLEncoded
AddURLEncoded [Char]

Query

null :: URLEncoded -> Bool Source

Is this URLEncoded data empty?

keys :: URLEncoded -> [String]Source

All of the keys from the URLEncoded value, in order, preserving duplicates

lookup :: URLShow a => a -> URLEncoded -> Maybe String Source

lookupAll :: URLShow a => a -> URLEncoded -> [String]Source

Return all values whose keys match the supplied key, in the order they appear in the query. Will return an empty list if no keys match.

lookup1 :: (URLShow a, MonadError e m) => a -> URLEncoded -> m String Source

Return the first value for the given key, or throw an error if the key is not present in the URLEncoded data.

lookupDefault :: URLShow a => String -> a -> URLEncoded -> String Source

pairs :: URLEncoded -> [(String, String)]Source

(%!) :: URLShow a => URLEncoded -> a -> Maybe String Source

Look up a key in a URLEncoded value and return the first matching value, or Nothing if there is no value that matches

Export

addToURI :: URLEncoded -> URI -> URI Source

Add this URL-encoded data to the query part of a URI, after any existing query arguments.

export :: URLEncoded -> String Source

Convert this URLEncoded object into an x-www-urlencoded String (The resulting string is 7-bit clean ASCII, containing only unreserved URI characters and %-encoded values)
