curl-aeson

A library for communicating with JSON over HTTP connection. Supports rich set of HTTP connectivity features provided by libcurl combined to the performance and elegancy of aeson. All HTTP methods are supported. Instances of ToJSON and FromJSON typeclasses can be transferred via this library. Session cookies and other HTTP options may be passed to libcurl if needed. This library is at its best when communicating with simple, non-standardized JSON interfaces. If you are implementing JSON-RPC compliant client or server, take a look at http://hackage.haskell.org/package/jmacro-rpc.
