- ctType :: String
- ctSubtype :: String
- ctParameters :: [(String, String)]
}
getContentType :: Monad m => Headers -> m ContentType
parseContentType :: Monad m => String -> m ContentType
showContentType :: ContentType -> String
data ContentTransferEncoding = ContentTransferEncoding String
getContentTransferEncoding :: Monad m => Headers -> m ContentTransferEncoding
data ContentDisposition = ContentDisposition String [(String, String)]
getContentDisposition :: Monad m => Headers -> m ContentDisposition
parseM :: Monad m => Parser a -> SourceName -> String -> m a
caseInsensitiveEq :: String -> String -> Bool
caseInsensitiveCompare :: String -> String -> Ordering
lexeme :: Parser a -> Parser a
ws1 :: Parser Char
p_token :: Parser String

Headers

type Headers = [(HeaderName, String)] #

HTTP headers.

newtype HeaderName #

A string with case insensitive equality and comparisons.

Content-type

data ContentType #

A MIME media type value. The Show instance is derived automatically. Use showContentType to obtain the standard string representation. See http://www.ietf.org/rfc/rfc2046.txt for more information about MIME media types.

Constructors

ContentType

Fields

ctType :: String
The top-level media type, the general type of the data. Common examples are "text", "image", "audio", "video", "multipart", and "application".
ctSubtype :: String
The media subtype, the specific data format. Examples include "plain", "html", "jpeg", "form-data", etc.
ctParameters :: [(String, String)]
Media type parameters. On common example is the charset parameter for the "text" top-level type, e.g. ("charset","ISO-8859-1").

getContentType :: Monad m => Headers -> m ContentType #

parseContentType :: Monad m => String -> m ContentType #

Parse the standard representation of a content-type. If the input cannot be parsed, this function calls fail with a (hopefully) informative error message.
