Description
Some helpers for parsing data out of a raw WAI Request.
- parseHttpAccept :: ByteString -> [ByteString]
- parseRequestBody :: BackEnd y -> Request -> IO ([Param], [File y])
- data RequestBodyType
- getRequestBodyType :: Request -> Maybe RequestBodyType
- sinkRequestBody :: BackEnd y -> RequestBodyType -> IO ByteString -> IO ([Param], [File y])
- type BackEnd a = ByteString -> FileInfo () -> IO ByteString -> IO a
- lbsBackEnd :: Monad m => ignored1 -> ignored2 -> m ByteString -> m ByteString
- tempFileBackEnd :: InternalState -> ignored1 -> ignored2 -> IO ByteString -> IO FilePath
- tempFileBackEndOpts :: IO FilePath -> String -> InternalState -> ignored1 -> ignored2 -> IO ByteString -> IO FilePath
- type Param = (ByteString, ByteString)
- type File y = (ByteString, FileInfo y)
- data FileInfo c = FileInfo {}
- parseContentType :: ByteString -> (ByteString, [(ByteString, ByteString)])
Documentation
parseHttpAccept :: ByteString -> [ByteString] Source
Parse the HTTP accept string to determine supported content types.
data RequestBodyType Source
Constructors
| UrlEncoded | |
| Multipart ByteString |
getRequestBodyType :: Request -> Maybe RequestBodyType Source
sinkRequestBody :: BackEnd y -> RequestBodyType -> IO ByteString -> IO ([Param], [File y]) 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.
Arguments
| :: IO FilePath | get temporary directory |
| -> String | filename pattern |
| -> InternalState | |
| -> ignored1 | |
| -> ignored2 | |
| -> IO ByteString | |
| -> IO FilePath |
Same as tempFileSink, 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.
Information on an uploaded file.
Constructors
| FileInfo | |
Fields

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.
