A FormURLEncoded datatype represents an ordered list of key-value pairs with possible duplicates. The encode function allows to transform FormURLEncoded into a Maybe String according to application/x-www-form-urlencoded. The decode function transforms a string into a Maybe FormURLEncoded structure.

Install form-urlencoded with Spago:

spago install form-urlencoded

Use the encode function to properly encode an array of key-value pairs, and the decode function to decode an encoded string.

> import Data.FormURLEncoded (fromArray, encode)
> import Data.Maybe (Maybe(..))
> import Data.Tuple (Tuple(..))

> encode $ fromArray 
>   [ Tuple "hey" Nothing
>   , Tuple "Oh" (Just "Let's go!")
>   ]
Just "hey&Oh=Let's+go!"

> decode "a=aa&b=bb"
Just (FormURLEncoded [(Tuple "a" (Just "aa")),(Tuple "b" (Just "bb"))])
