I'm trying to transform CURL request with HTTPoison in Elixir Phoenix. When I run CURL request commend, It work fine.I got "415 Unsupported media type" error when I try with HTTPoison.

Phoenix/Elixir - cURL works, but HTTPoison fails

Here is my CURL request

curl -u "user:password" -i -H "Accept:application/json" -X POST -d

Here is my Httpoison request

url = "myurl"
orderid = "myorderid"
headers = ["Accept", "application/json"]
request_body = '{"type" : "bank", 
         "method" : 0,
         "amount" : #{amount},
                 "receiver" : "CCC"
         "info1" : #{orderid}}'
dicoba = HTTPoison.post(url, headers, request_body, hackney: [basic_auth: {"#{user}", "#password"}]) |> IO.inspect

The curl request is in the content type application/x-www-form-urlencoded, but your HTTPoison request is, well, malformed. You passed a charlist to the request body, where HTTPoison expects a binary, and you didn't specify the request's content type.

To create a application/x-www-form-urlencoded request body, you can use the function URI.encode_query/1.

url = ""
payload = %{
  "amount" => 100,
  "method" => 0,
  "type" => "bank",
  "receiver" => "CCC",
  "info1" => "hello"
request_body = URI.encode_query(payload)
headers = [
  {"Accept", "application/json"}, 
  {"Content-Type", "application/x-www-form-urlencoded; charset=utf-8"}
dicoba = HTTPoison.post(url, headers, request_body, hackney: [basic_auth: {"#{user}", "#password"}])
