java ResponseBuilder toString（）以字符串形式返回对象类，而不仅仅是原始响应字符串

Question

我目前正在从Java ASK-SDK v1迁移到Java ASK SDK v2

我试图使用我建立的ResponseBuilder类返回webhook调用，并且数据是正确的，但是当我试图用JSON文本填充HTTP正文时，ResponseBuilder.toString()值不仅仅用字符串填充数据，我得到以下结果：

Optional[class Response {
    outputSpeech: class SsmlOutputSpeech {
        class OutputSpeech {
            type: SSML
            playBehavior: null
        }
        ssml: <speak>Some of the things you can say are What would you like to do?</speak>
    }
    card: null
    reprompt: class Reprompt {
        outputSpeech: class SsmlOutputSpeech {
            class OutputSpeech {
                type: SSML
                playBehavior: null
            }
            ssml: <speak>You can say ..., is that what you want?</speak>
        }
    }
    directives: []
    shouldEndSession: false
    canFulfillIntent: null
}]

有没有其他方法可以获取响应主体的字符串？BaseSkillResponse有一个getResponse()调用，但是，我不知道如何使用该类生成字符串响应输出

Answer 1

通过执行以下操作解决此问题：

        public String toJsonString(Response response)throws IOException 
        {
          JacksonSerializer jacksonSerializer = new JacksonSerializer();
          constructedResponse = jacksonSerializer.serialize(response);

          JSONObject jsonObject = new JSONObject();

          jsonObject.put("response",constructedResponse);
        }

在我的课堂上，我能够通过以下方式获得字符串：

 private static final ObjectMapper OBJECT_MAPPER = new ObjectMapper();

 myFunction(){
     try{
         return toJsonString(responseBuilder.build().get());
     } catch(IOException e) {
         e.printStackTrace();
     }
 }

 public String toJsonString(Response response)throws IOException {
     return OBJECT_MAPPER.writeValueAsString(response);
 }
