Description

This part of the library provides you with utilities to create WebSockets clients (in addition to servers).

Synopsis

runClientWith :: String -> Int -> String -> ConnectionOptions -> Headers -> ClientApp a -> IO a
runClientWithSocket :: Socket -> String -> String -> ConnectionOptions -> Headers -> ClientApp a -> IO a
runClientWithStream :: Stream -> String -> String -> ConnectionOptions -> Headers -> ClientApp a -> IO a
newClientConnection :: Stream -> String -> String -> ConnectionOptions -> Headers -> IO Connection
createRequest :: Protocol -> ByteString -> ByteString -> Bool -> Headers -> IO RequestHead
data Protocol = Hybi13
defaultProtocol :: Protocol
checkServerResponse :: Stream -> RequestHead -> IO ()
streamToClientConnection :: Stream -> ConnectionOptions -> IO Connection

Documentation

type ClientApp a = Connection -> IO a #

A client application interacting with a single server. Once this IO action finished, the underlying socket is closed automatically.

runClient #

Arguments

:: String	Host
-> Int	Port
-> String	Path
-> ClientApp a	Client application
-> IO a

runClientWith #

Arguments

:: String	Host
-> Int	Port
-> String	Path
-> ConnectionOptions	Options
-> Headers	Custom headers to send
-> ClientApp a	Client application
-> IO a

runClientWithSocket #

Arguments

:: Socket	Socket
-> String	Host
-> String	Path
-> ConnectionOptions	Options
-> Headers	Custom headers to send
-> ClientApp a	Client application
-> IO a

runClientWithStream #

Arguments

:: Stream	Stream
-> String	Host
-> String	Path
-> ConnectionOptions	Connection options
-> Headers	Custom headers to send
-> ClientApp a	Client application
-> IO a

newClientConnection #

Arguments

:: Stream	Stream that will be used by the new `Connection`.
-> String	Host
-> String	Path
-> ConnectionOptions	Connection options
-> Headers	Custom headers to send
-> IO Connection

Build a new Connection from the client's point of view.

WARNING: Be sure to call close on the given Stream after you are done using the Connection in order to properly close the communication channel. runClientWithStream handles this for you, prefer to use it when possible.

Instance details Defined in Network.WebSockets.Protocol Methods showsPrec :: Int -> Protocol -> ShowS # show :: Protocol -> String # showList :: [Protocol] -> ShowS #

defaultProtocol :: Protocol #

checkServerResponse :: Stream -> RequestHead -> IO () #

Check the response from the server. Throws OtherHandshakeException on failure

streamToClientConnection :: Stream -> ConnectionOptions -> IO Connection #

Build a Connection from a pre-established stream with already finished handshake.

NB: this will not perform any handshaking.
