Setting the form values in a post https request

I want to perform a request with the certain headers, cookies and form values. Here is how I'm doing that:

  import Network.HTTP.Conduit
  import Network.HTTP.Types
  --.......omitted


  configReq r = r { method = methodPost
  , requestHeaders = (requestHeaders r) ++ [
      (DS.fromString "Referer", DS.fromString "https://server...."),
      (DS.fromString "SomeHeader2", DS.fromString "fdsfdsfds")
    ]
  , requestBody = RequestBodyLBS (Aeson.encode $ Map.fromList [("email", "[email protected]"), ("password", "7890")])
  , secure = True
  , cookieJar = [myCookie]
 }

This seems like it should work. But it doesn't because a server returns 400 --> "X-Response-Body-Start","Invalid input." no matter what the email and the password are. Note that this is not a request which perform something per se, it is an authentication request (the same one you send when you click "login" button) that's why it has email and password form values (the same as on its /login page).

I figure that even so the form values email and password are in the request, they have to be set differently, meaning they have to be not in requestBody but in some different place.

So for now the question is where do I have to put email and password if not in requestBody ?

Most likely, the web server is expected URL encoded form data, not a JSON request body. You can use the aptly-named urlEncodedBody function for that purpose.
