class HasHeaders x where

HasHeaders is a type class for types containing HTTP headers, allowing you to write overloaded header manipulation functions for both Request and Response data types, for instance.

Methods

getHeaders :: x -> [Header]

setHeaders :: x -> [Header] -> x

Instances

HasHeaders (Request a)

HasHeaders (Response a)

type T = Header

data Header

The Header data type pairs header names & values.

Constructors

Header HeaderName String

Instances

Show Header

cons :: Name -> String -> T

type Name = HeaderName

data HeaderName

HTTP HeaderName type, a Haskell data constructor for each specification-defined header, prefixed with Hdr and CamelCased, (i.e., eliding the - in the process.) Should you require using a custom header, there's the HdrCustom constructor which takes a String argument.

Encoding HTTP header names differently, as Strings perhaps, is an equally fine choice..no decidedly clear winner, but let's stick with data constructors here.

consName :: String -> Name

getName :: T -> Name

getValue :: T -> String

setMany :: HasHeaders x => x -> [T] -> x

getMany :: HasHeaders x => x -> [T]

modifyMany :: HasHeaders x => ([T] -> [T]) -> x -> x

insert :: HasHeaders a => Name -> String -> a -> a

Inserts a header with the given name and value. Allows duplicate header names.

insertMany :: HasHeaders a => [T] -> a -> a

Inserts multiple headers.

insertIfMissing :: HasHeaders a => Name -> String -> a -> a

Adds the new header only if no previous header shares the same name.

retrieveMany :: HasHeaders a => Name -> a -> [T]

Gets a list of headers with a particular Name.

replace :: HasHeaders a => Name -> String -> a -> a

Removes old headers with duplicate name.

find :: HasHeaders a => Name -> a -> Maybe String

Lookup presence of specific Name in a list of Headers Returns the value from the first matching header.

findMany :: HasHeaders a => Name -> a -> [String]

lookup :: Name -> [T] -> Maybe String

Deprecated: Call find using the [Header] instance of HasHeaders
