parseFormData :: Request -> IO ([Param], [File ByteString]) Source #
Parse form data uploaded with a Content-Type of either
www-form-urlencoded or multipart/form-data to return a
list of parameter names and values and a list of uploaded
files and their information.
contentTypeMatches :: Monad m => [MediaType] -> Webmachine m Bool Source #
Returns True if the request's Content-Type header is one of the
provided media types. If the Content-Type header is not present,
this function will return True.
redirectTemporarily :: Monad m => ByteString -> Webmachine m a Source #
Issue an HTTP 302 (Found) response, with location as the destination.
redirectPermanently :: Monad m => ByteString -> Webmachine m a Source #
Issue an HTTP 301 (Moved Permantently) response,
with location as the destination.
resourceToWai :: AirshipConfig -> RoutingSpec IO () -> ErrorResponses IO -> Application Source #
Given a RoutingSpec, a 404 resource, and a user state s, construct a WAI Application.
resourceToWaiT :: Monad m => AirshipConfig -> (AirshipRequest -> m Response -> IO Response) -> RoutingSpec m () -> ErrorResponses m -> Application Source #
Given a 'AirshipConfig, a function to modify the Response based on the
AirshipRequest and the Response (like WAI middleware), a 'RoutingSpec,
and ErrorResponses construct a WAI Application.
resourceToWaiT' :: Monad m => AirshipConfig -> (AirshipRequest -> m Response -> IO Response) -> Trie (RouteLeaf m) -> ErrorResponses m -> Application Source #
Like resourceToWaiT, but expects the RoutingSpec to have been
evaluated with runRouter. This is more efficient than resourceToWaiT, as
the routes will not be evaluated on every request.
Given routes :: RoutingSpec IO (), resourceToWaiT' can be invoked like so:
resourceToWaiT' cfg (const id) (runRouter routes) errors
appendRequestPath :: Monad m => [Text] -> Webmachine m ByteString Source #
lookupParam :: Monad m => Text -> Webmachine m Text Source #
Lookup routing parameter and return 500 Internal Server Error if not found. Not finding the paramter usually means the route doesn't match what the resource is expecting.
lookupParam' :: Monad m => Text -> Webmachine m (Maybe Text) Source #
Lookup routing parameter.
