Получение нулевого ответа даже в случае успешного запроса в Retrofit 2

Question

Я получаю null в корпусе Response в модификации 2. тогда как в теле у меня есть действительные данные.

//using retrofit 
    HttpLoggingInterceptor logging = new HttpLoggingInterceptor(); 
    logging.setLevel(HttpLoggingInterceptor.Level.BODY); 
    OkHttpClient.Builder httpClient = new OkHttpClient.Builder(); 
    httpClient.addInterceptor(logging); 

    Retrofit adapter = new Retrofit.Builder() 
         .baseUrl(Config.CUSTOMER_URL) 
         .addConverterFactory(GsonConverterFactory.create()) 
         .client(httpClient.build()) 
         .build(); 
    RegisterCustomer api = adapter.create(RegisterCustomer.class); 
    Call<Model> call = api.registerCustomer(custName.getText().toString() , phoneNumber.getText().toString(), address.getText().toString(), "abc"); 
    call.enqueue(new Callback<Model>() { 
     @Override 
     public void onResponse(Call<Model> call, retrofit2.Response<Model> response) { 
      if(response.isSuccessful()) 
      { 
       Log.d("CallBack",response.body().getCustId()+"###"+response.body().getCustUri()+response.code()); 
      } 

     } 

     @Override 
     public void onFailure(Call<Model> call, Throwable t) { 
      Log.d("CallBack","error saving customer"+t.getMessage()); 

     } 
    }); 

Мой интерфейс.

public interface RegisterCustomer 
{ 
    @FormUrlEncoded 
    @POST("customer") 
    Call<Model> registerCustomer(
      @Field("cust_name") String cust_name, 
      @Field("phone") String phone, 
      @Field("address") String address, 
      @Field("apikey") String apikey 
    //  Callback<Response> callback 
    ); 
}

Мой действительный ответ { "cust_id": 18, "cust_uri": "/ клиент/18"} Я получаю нулевой ### null201 также данные успешно сохраняются на сервере.

Answer 1

Можете ли вы проверить ваш Model.java должен быть, как показано ниже.

public class Model { 

@SerializedName("cust_id") 
@Expose 
private Integer custId; 
@SerializedName("cust_uri") 
@Expose 
private String custUri; 

public Integer getCustId() { 
return custId; 
} 

public void setCustId(Integer custId) { 
this.custId = custId; 
} 

public String getCustUri() { 
return custUri; 
} 

public void setCustUri(String custUri) { 
this.custUri = custUri; 
} 

}
