get String Из опционной версии 2.0.0 beta1

Question

Я хотел получить строку json из версии 2, но мне не нужен объект. пожалуйста, помогите получить строку, когда call response.body() из метода onResponse.

public void getLoginResultFromWebservice(int customerID, String user, String pass) { 
    String action = "Login"; 
    long timeMillis = System.currentTimeMillis(); 
    String key = new String(Hex.encodeHex(DigestUtils.md5(G.HASH_KEY + timeMillis))); 
    String customerId = String.valueOf(customerID); 
    String username = user; 
    String password = pass; 
    Retrofit retrofit = new Retrofit.Builder() 
      .baseUrl(G.URL_Webservice_Base) 
      .client(U.getClient()) 
      .build(); 
    Webservice webservice = retrofit.create(Webservice.class); 
    Call<String> call = webservice.getLoginResult(action,key,customerId,username,password); 
    call.enqueue(new Callback<String>() { 
     @Override 
     public void onResponse(Response<String> response) { 
      U.log(" ActivityLogin : OnResponse "); 
      U.log(" ActivityLogin : Result " + response.body().toString()); 
     } 

     @Override 
     public void onFailure(Throwable t) { 
      U.log("ActivityLogin On Failure"); 
     } 
    }); 
} 

EDIT: я нашел решение:

new Retrofit.Builder() 
    .baseUrl(G.URL_Webservice_Base) 
    // add a converter for String 
    .addConverter(String.class, new ToStringConverter()) // add this 
    //.addConverterFactory(GsonConverterFactory.create()) // remove this line 
    .build() 
    .create(Webservice.class); 

ToStringConverter.class

public final class ToStringConverter implements Converter<String> { 

@Override 
public String fromBody(ResponseBody body) throws IOException { 
    return body.string(); 
} 

@Override 
public RequestBody toBody(String value) { 
    return RequestBody.create(MediaType.parse("text/plain"), value); 
} 
}

вы можете попробовать

public ApiService getBase64StrService() { 
    if (retrofit == null) { 
     retrofit = new Retrofit 
       .Builder() 
       .baseUrl(endpoint) 
       .addCallAdapterFactory(RxJavaCallAdapterFactory.create()) 
       .addConverter(String.class, new Base64StringConverter()) 
       .build(); 
    } 
    if (service == null) { 
     service = retrofit.create(ApiService.class); 
    } 

    return service; 
} 



static class Base64StringConverter implements Converter { 

    @Override 
    public Object fromBody(ResponseBody body) throws IOException { 
     InputStream reader = null; 
     try { 
      reader = body.byteStream(); 
      ByteArrayOutputStream writer = new ByteArrayOutputStream(); 
      byte[] buffer = new byte[1024 * 8]; 
      int size = -1; 
      while ((size = reader.read(buffer)) > 0) { 
       writer.write(buffer, 0, size); 
      } 
      String result = new String(writer.toByteArray()); 
      return result; 
     } finally { 
      try { 
       if (reader != null) 
        reader.close(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 

    } 

    @Override 
    public RequestBody toBody(Object value) { 
     return null; 
    } 
}
