Methods with body should get encode argument

[hadley]

Which can be json, xml, mutlipart or form. Need to preserve existing multipart behaviour (or at least warn)

Is this issue the reason why I can't POST with JSON in the body, but I can with a list?

require(httr)

dst_url <- "http://api.statbank.dk/v1/data"
final_request <- list("table" = "folk1",
                      "lang" = "en",
                      "format" = "CSV",
                      "valuePresentation" = "Default")

## This works
POST(url=dst_url, body=final_request, multipart=FALSE)

## But this doesn't
final_request <- jsonlite::toJSON(x=final_request)
POST(url=dst_url, body=final_request, multipart=FALSE)
POST(url=dst_url, body=final_request, multipart=TRUE)
POST(url=dst_url, body=final_request, multipart=FALSE, add_headers("Content-Type" = "application/json"))
POST(url=dst_url, body=final_request, multipart=TRUE, add_headers("Content-Type" = "application/json"))

Are you sure that API accepts json? The fact that the first one works suggests that it doesn't.

The API recommends that you POST the requests as JSON, but you can also url encode the requests. It can answer in XML or JSON except for "data" requests (others are table, tableinfo and subject). I thought that I was posting a JSON request in the first POST, but I just found the verbose() function and now see that I don't. I think I'll try to work with the url encoding instead. Thanks!
