Description

Some helpers for parsing data out of a raw WAI Request.

Synopsis

Documentation

parseHttpAccept :: ByteString -> [ByteString] #

Parse the HTTP accept string to determine supported content types.

type BackEnd a #

Arguments

 = ByteString

parameter name

-> FileInfo () 
-> IO ByteString 
-> IO a 

A file uploading backend. Takes the parameter name, file name, and a stream of data.

lbsBackEnd :: Monad m => ignored1 -> ignored2 -> m ByteString -> m ByteString #

Store uploaded files in memory

tempFileBackEnd :: InternalState -> ignored1 -> ignored2 -> IO ByteString -> IO FilePath #

Save uploaded files on disk as temporary files

Note: starting with version 2.0, removal of temp files is registered with the provided InternalState. It is the responsibility of the caller to ensure that this InternalState gets cleaned up.

tempFileBackEndOpts #

Arguments

:: IO FilePath

get temporary directory

-> String

filename pattern

-> InternalState 
-> ignored1 
-> ignored2 
-> IO ByteString 
-> IO FilePath 

Same as tempFileBackEnd, but use configurable temp folders and patterns.

type Param = (ByteString, ByteString) #

Post parameter name and value.

type File y = (ByteString, FileInfo y) #

Post parameter name and associated file information.

data FileInfo c #

Information on an uploaded file.

Instances

Eq c => Eq (FileInfo c) # 

Methods

(==) :: FileInfo c -> FileInfo c -> Bool #

(/=) :: FileInfo c -> FileInfo c -> Bool #

Show c => Show (FileInfo c) # 

Methods

showsPrec :: Int -> FileInfo c -> ShowS #

show :: FileInfo c -> String #

showList :: [FileInfo c] -> ShowS #

parseContentType :: ByteString -> (ByteString, [(ByteString, ByteString)]) #

Parse a content type value, turning a single ByteString into the actual content type and a list of pairs of attributes.
