Description

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

Synopsis

Documentation

parseHttpAccept :: ByteString -> [ByteString] Source #

Parse the HTTP accept string to determine supported content types.

type BackEnd a Source #

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 Source #

Store uploaded files in memory

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

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 Source #

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) Source #

Post parameter name and value.

type File y = (ByteString, FileInfo y) Source #

Post parameter name and associated file information.

data FileInfo c Source #

Information on an uploaded file.

Instances

Eq c => Eq (FileInfo c) Source # 

Methods

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

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

Show c => Show (FileInfo c) Source # 

Methods

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

show :: FileInfo c -> String #

showList :: [FileInfo c] -> ShowS #

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

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