API我必须使用sucks,并始终返回HTTP 200.但有时有适当的响应:
[{"blah": "blah"}, {"blah": "blah"}]
有时,有错误:
{"error": "Something went wrong", "code": 123}
我正在使用Retrofit2与Gson转换器和Rx适配器:
final Api api = new Retrofit.Builder()
.baseUrl(URL)
.client(client)
.addCallAdapterFactory(RxJavaCallAdapterFactory.createWithScheduler(Schedulers.io()))
.addConverterFactory(GsonConverterFactory.create())
.build()
.create(Api.class);
现在,当我收到错误响应时,将onError调用处理程序,但会出现以下异常:

我该如何解决？如果我可以在onError处理程序中获得响应,我可以使用适当的错误模型类重新解析它.但似乎我无法得到原始的回应.
