I worked up a little application for Etrade's API, which is at least the same basic idea. This was some time ago and memory is pretty fuzzy, but ... I see that for some reason I modified hoauth Consumer.hs, replacing showURL with a path-to-text function I wrote myself, and I use my own version of the signRq function from that module that returns an unpacked request value. I'm sure it would be much more helpful to say what problems I was to solving there, sorry! Authentication was the hard part, naturally. Donn
... I see that for some reason I modified hoauth Consumer.hs, replacing showURL with a path-to-text function I wrote myself, and I use my own version of the signRq function from that module that returns an unpacked request value.
On further examination, I see I'm using my own version of CurlHttpClient, where - in runClient, if result is not a success code, return (respBody rsp) instead of (show errno) - add CurlPartialFile to successCodes - added (CurlIPResolve 1) to opts to avoid platform IPv6 bug Then authentication re-evaluates runClient success/error, parsing the results and potentially turning success into error, and for all errors makes up a reasonably detailed text rendition.
