Hi Jean,
The JAX-RS has full support for web forms, it should be fairly easy to do
with WebClient for example:
import javax.ws.rs.core.Form;
import javax.ws.rs.core.Response;
final WebClient client = WebClient
.create(address)
.accept("application/json")
.type("application/x-www-form-urlencoded")
.path("/");
final Form form = new Form();
form.param("token", accessToken);
try (Response response = client.post(form)) {
...
}
I hope it answers your question, thank you.
Best Regards,
Andriy Redko
