Retrofit/RxJava - 獲取http響應代碼

Question

Android，Retrofit，RxJava。請看這個例子調用：

mcityService.signOut(signOutRequest) 
       .subscribeOn(Schedulers.io()) 
       .observeOn(AndroidSchedulers.mainThread()) 
       .subscribe(resp -> 
       { 
        busyIndicator.dismiss(); 
        finish(); 
       }, throwable -> 
       { 
        Log.d(tag, throwable.toString()); 
        busyIndicator.dismiss(); 
        Toast.makeText(this,throwable.getMessage(),Toast.LENGTH_LONG).show(); 
        finish(); 
       }); 

有沒有人知道如何從throwable中獲取錯誤代碼（如錯誤號）？我能夠獲得完整的堆棧跟蹤或消息（如上所示）。如何捕獲錯誤代碼？從拋出

錯誤代碼：這裏

Answer 1

只要使用鑄造??

mcityService.signOut(signOutRequest) 
       .subscribeOn(Schedulers.io()) 
       .observeOn(AndroidSchedulers.mainThread()) 
       .subscribe(resp -> 
       { 
        busyIndicator.dismiss(); 
        finish(); 
       }, throwable -> 
       { 
        Log.d(tag, throwable.toString()); 
        Log.d(code, ((HttpException)throwable).code()); 

        busyIndicator.dismiss(); 
        Toast.makeText(this,throwable.getMessage(),Toast.LENGTH_LONG).show(); 
        finish(); 
       });

Retrofit 2 + Rxjava handling error是你的答案

   @Override 
      public void onError(Throwable e) { 
       if (e instanceof HttpException) { 
        ResponseBody body = ((HttpException) e).response().errorBody(); 

        Converter<ResponseBody, Error> errorConverter = 
         application.getRetrofit().responseBodyConverter(Error.class, new Annotation[0]); 
       // Convert the error body into our Error type. 
        try { 
         Error error = errorConverter.convert(body); 
         Log.i("","ERROR: " + error.message); 
         mLoginView.errorText(error.message); 
        } catch (IOException e1) { 
        e1.printStackTrace(); 
        } 
       } 



      static class Error{ 
      String message; 
      }
