Http.Header

Documentation

data Header

An HTTP header. This type does not enforce a restricted character set. If, for example, the user creates a header whose key has a colon character, the resulting request will be malformed.

Methods

(==) :: Header -> Header -> Bool

(/=) :: Header -> Header -> Bool

decodeMany :: Int -> Bytes -> Maybe (SmallArray Header)

Parse headers. Expects two CRLF sequences in a row at the end. Fails if leftovers are encountered.

parser :: Parser () s Header

Parse a single HTTP header including the trailing CRLF sequence. From RFC 7230:

token          = 1*tchar
tchar          = "!" / "#" / "$" / "%" / "&" / "'" / "*"
               / "+" / "-" / "." / "^" / "_" / "`" / "|" / "~" 
               / DIGIT / ALPHA

header-field   = field-name ":" OWS field-value OWS
field-name     = token
field-value    = *( field-content / obs-fold )
field-content  = field-vchar [ 1*( SP / HTAB ) field-vchar ]
field-vchar    = VCHAR / obs-text
