Retrofit 2.0 how to get deserialised error response.body

Question

I\'m using Retrofit 2.0.0-beta1.

In tests i have an alternate scenario and expect error HTTP 400

I would like to have retrofit.Respons

Answer 1

In Retrofit 2.0 beta2 this is the way that I'm getting error responses:

1. Synchronous

   try {
      Call call = backendServiceApi.register(data.in.account, data.in.password,
              data.in.email);
      Response response = call.execute();
      if (response != null && !response.isSuccess() && response.errorBody() != null) {
          Converter errorConverter =
                  MyApplication.getRestClient().getRetrofitInstance().responseConverter(BasicResponse.class, new Annotation[0]);
          BasicResponse error = errorConverter.convert(response.errorBody());
          //DO ERROR HANDLING HERE
          return;
      }
      RegistrationResponse registrationResponse = response.body();
      //DO SUCCESS HANDLING HERE
   } catch (IOException e) {
      //DO NETWORK ERROR HANDLING HERE
   }
   

2. Asynchronous

   Call call = service.loadRepo();
   call.enqueue(new Callback() {
       @Override
       public void onResponse(Response response, Retrofit retrofit) {
           if (response != null && !response.isSuccess() && response.errorBody() != null) {
               Converter errorConverter =
                   retrofit.responseConverter(BasicResponse.class, new Annotation[0]);
               BasicResponse error = errorConverter.convert(response.errorBody());
               //DO ERROR HANDLING HERE
               return;
           }
           RegistrationResponse registrationResponse = response.body();
           //DO SUCCESS HANDLING HERE
       }
   
       @Override
       public void onFailure(Throwable t) {
           //DO NETWORK ERROR HANDLING HERE
       }
   });
   

Update for Retrofit 2 beta3:

1. Synchronous - not changed

2. Asynchronous - Retrofit parameter was removed from onResponse

   Call call = service.loadRepo();
   call.enqueue(new Callback() {
       @Override
       public void onResponse(Response response) {
           if (response != null && !response.isSuccess() && response.errorBody() != null) {
               Converter errorConverter =
                   MyApplication.getRestClient().getRetrofitInstance().responseConverter(BasicResponse.class, new Annotation[0]);
               BasicResponse error = errorConverter.convert(response.errorBody());
               //DO ERROR HANDLING HERE
               return;
           }
           RegistrationResponse registrationResponse = response.body();
           //DO SUCCESS HANDLING HERE
       }
   
       @Override
       public void onFailure(Throwable t) {
           //DO NETWORK ERROR HANDLING HERE
       }
   });
