Major When a query parameter has the same value as that in the request body on POST method - the value of that parameter is missing later
Here is an example:
@Path("/my_path") @Produces(MediaType.TEXT_HTML) public interface MyService { @GET Response readAction(@QueryParam("action") String action); @POST Response postReadAction(@FormParam("action") String action) }
$ curl -d "action=test" "http://myserver/my_path" action: test e.g. the action parameter in the body is read and this is the expected answer. $ curl -d "action=test1" "http://myserver/my_path?action=test" action: test1 This is also OK, the verb is POST and the action value is test1 (as it is in the body). $ curl -d "action=test" "http://myserver/my_path?action=test" action: In this case (action parameter appears as form and query parameter and has the same value) the action parameter value is missing.
*********
The problem is in org.jboss.resteasy.plugins.server.servlet.HttpServletInputMessage#getDecodedFormParameters() - there is an explicit check whether the same parameter and value is passed as query param, if yes - the value is ignored.
if (!queryValues.contains(val))
{
decodedFormParameters.add(name, val);
}
I think that issue is similar(if not the same) to this one: https://issues.jboss.org/browse/RESTEASY-760.
