How can I do an HTTPS request in Haskell?

Question

For example, I want to obtain a request token via HTTPS POST from Dropbox API

P.S.: I am using Windows 8

If you're doing OAuth, you might want to use the [haskell oauth](http://hackage.haskell.org/package/hoauth-0.3.3) package instead. — Vlad the Impala, Apr 03 '12 at 03:52

Thanks to packages like http-conduit, which is backed by tls, you can use simpleHttp for HTTPS.

> import Network.HTTP.Conduit
> simpleHttp "https://github.com"
...  big ugly bytestring that can be parsed in so many ways...

That is one huge package... or it sure has a lot of dependencies! – Andriy Drozdyuk Apr 03 '12 at 14:14

For less dependencies, use http-client with http-client-tls:

{-# LANGUAGE OverloadedStrings #-}

import qualified Network.HTTP.Client     as H
import qualified Network.HTTP.Client.TLS as H

main :: IO ()
main = do
  httpman <- H.newManager H.tlsManagerSettings
  let req = H.setQueryString [("q", Just "r")] "https://httpbin.org/get"
  response <- H.httpLbs req httpman
  print response

(Those packages were factored out of http-conduit; if you have no need of conduit, sticking with http-client will decrease your dependency footprint.)
