Symptom

In the getResponse function from https://github.com/FederatedAI/FATE-Serving/blob/master/fate-serving-common/src/main/java/com/webank/ai/fate/serving/common/utils/HttpAdapterClientPool.java, private static HttpAdapterResponse getResponse(HttpRequestBase request) { CloseableHttpResponse response = null; try { response = HttpClientPool.getConnection().execute(request, HttpClientContext.create()); HttpEntity entity = response.getEntity(); String result = EntityUtils.toString(entity, Dict.CHARSET_UTF8); return JsonUtil.json2Object(result, HttpAdapterResponse.class); <--will always return null, } ... } JsonUtil.json2Object(result, HttpAdapterResponse.class) will always return null, because the result is not an HttpAdapterResponse object.

solution

1.update getResponse fucntion like this. 2.rename HttpAdapterByHeader class to HttpAdapter, these two classes are duplicated. try { ... String data = EntityUtils.toString(entity, Dict.CHARSET_UTF8); int statusCode = response.getStatusLine().getStatusCode(); HttpAdapterResponse result = new HttpAdapterResponse(); result.setCode(statusCode); result.setData(JsonUtil.json2Object(data,Map.class)); #data is only an Map<String,Object> object in HttpAdapterResponse return result; } catch (IOException ex) { ... } finally { ... }
