Question

我正在尝试使用以下代码来推送json数据但是，当我直接发送json数据时，无法获得所需的结果，意味着如果用String input = jsonString替换## line1;

我的json String构造为：

ArrayList <ContactData> documents;
Gson g = new Gson();
String jsonString = g.toJson(documents);

然后将json字符串传递给我的方法

private void pushDataToClientURL(String clientURL, String jsonString)
        {
            try {

                log.debug("starting pushing data to Client URL");

                URL targetUrl = new URL(clientURL);

                HttpURLConnection httpConnection = (HttpURLConnection) targetUrl.openConnection();
                httpConnection.setDoOutput(true);
                httpConnection.setRequestMethod("POST");
                httpConnection.setRequestProperty("Content-Type", "application/json");
                OutputStream outputStream = httpConnection.getOutputStream();
            ##line1 String input ="{\"statusCode\":1,\"type\":\"Liam\",\"age\":22,\"value\":\"Marco\"}";

                outputStream.write(input.getBytes());
                outputStream.flush();

                if (httpConnection.getResponseCode() != 200) {
                    throw new RuntimeException("Failed : HTTP error code : "
                            + httpConnection.getResponseCode());
                }

                BufferedReader responseBuffer = new BufferedReader(new InputStreamReader(
                        (httpConnection.getInputStream())));

                String output;

                log.debug("Output from Server:\n");

                while ((output = responseBuffer.readLine()) != null) {
                    System.out.println(output);
                }

                httpConnection.disconnect();

            } catch (MalformedURLException e) {

                e.printStackTrace();

            } catch (IOException e) {

                e.printStackTrace();

            }

        }

这是我的休息服务的代码

@POST
        @Path("/dataPosting")
        @Consumes(MediaType.APPLICATION_JSON)
        public Response consumeJSON(ContactData bean){

            String result = bean.toString();

            return Response.status(200).entity(result).build();
        }

    Getting error


Exception in thread "Thread-3" java.lang.RuntimeException: Failed : HTTP error code : 400
    at com.rest.test.profiling.ProfilingDataPushJOB.pushDataToClientURL(ProfilingDataPushJOB.java:127)

将您的JSON字符串转换为字符串实体，并将setEntity转换为http post请求。 StringEntity se = new StringEntity（jsonString）;

将json数据发布到URL时出错
