X-www-form-urlencoded request bodies parsing

tapir

I’ve already created an github issue for this,
just bringing it here, might be useful

Guys, I’m not sure if tapir is able to parse x-www-form-urlencoded request bodies

I use .in(formBody[A]) and Codec.formCaseClassCodec for type A.

for instance, my endpoint looks like this:

ztapir
    .endpoint
    .post
    .in(formBody[UpdatePoliciesForm])

where UpdatePoliciesForm is the following:

import sttp.tapir.generic.auto._

final case class UpdatePasswordForm(
    login: Login,
    password: Password
) extends Serializable

object UpdatePasswordForm {
  implicit val formBodyCodec: Codec[String, UpdatePasswordForm, CodecFormat.XWwwFormUrlencoded] =
    Codec.formCaseClassCodec
}

So requests like

--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'login=dmedser' \
--data-urlencode 'password=p@ssw0rd' \

lead to an error, while only the following request could be parsed successfully

--header 'Content-Type: text/plain' \
--data-raw 'login=dmedser&password=p@ssw0rd'

but Content-Type and data format aren’t what I expect

If you take a look at formBody you may notice that it seems the same as raw string body

def formBody[T: Codec[String, *, CodecFormat.XWwwFormUrlencoded]]: EndpointIO.Body[String, T] =
  stringBodyUtf8AnyFormat[T, CodecFormat.XWwwFormUrlencoded](implicitly)

I’m not sure if that’s the reason, just FYI

Take a look at github issue I mentioned in post above, the solution is there
