How to set "Content-type" header in RestEasy Client framework using a proxy interface?

I am using Resteasy client proxy framework to talk to a REST API. I have defined some methods on the proxy interface but unfortunately, I have some issues related to Content-Type not being set properly when sending http requests, which gives me an http 400 (Bad Request) error code since the remote API is expecting the Content-type header param to be application/json.

Here is how it looks like :

@Path("/")
public interface RestAPIClient {

  @POST
  @Path("/send")
  String send(@CookieParam("token") String token, @FormParam("name") String id, @FormParam("message") String message, @FormParam("emails") List<String> emails);

}

is there a way to set the "Content-type" header as "application/json" directly at the proxy interface level ? using some annotations maybe ?

thanks

As well as using:

@Consumes(MediaType.APPLICATION_JSON)

you need to ensure there is actually content in the body of the request (not just params).

If there is no content, then the Content-Type header won't be set.

I you try a 

@Consumes(MediaType.APPLICATION_JSON)

on the POST ?

Take care of many things : you need to have an "entity" object who is send in the method (not @CookieParam, or @FormParam). And in

So your method must be like :

@POST
@Path("/auth")
@Consumes(MediaType.APPLICATION_JSON)
ConnectionInformation auth(@CookieParam("name") String name, @CookieParam("password") String password, MyJSONObject entity);

and "entity" will produce the 

Content-Type: application/json

you need.
