HaXR — the Haskell XML-RPC library
Christopher Milton came up with the HaXR name, thanks!
Example are available in the examples/ folder in the darcs repository. Here we talk about a couple of them.
This is a simple CGI-based server with only one method that takes two integers and returns their sum.
import Network.XmlRpc.Server add :: Int -> Int -> IO Int add x y = return (x + y) main = cgiXmlRpcServer [("examples.add", fun add)]
Note: the argument to fun can be a function that takes any number of arguments.
This is a client that calls the method implemented by the server above and prints the result.
import Network.XmlRpc.Client server = "http://localhost/~bjorn/cgi-bin/simple_server" add :: String -> Int -> Int -> IO Int add url = remote url "examples.add" main = do let x = 4 y = 7 z <- add server x y putStrLn (show x ++ " + " ++ show y ++ " = " ++ show z)
Note: the function returned by remote can be a function that takes any number of arguments.
Use the online copy of the API documentation.
There used to be a separate haxr-th, now everything is available in haxr.
