用Json響應獲取請求？

Question

我有以下類從json響應中返回一個spefic字段。 這裏要求的方法是在帖子後面。我如何使用get方法做​​到這一點？ 此外，我想用頭

CloseableHttpClient httpClient = HttpClients.createDefault(); 
    HttpPost post = new HttpPost(
      ""); 
    post.addHeader("Auth-Token", authenticationValues.getAuthToken()); 
    post.addHeader("device-id", authenticationValues.getDeviceId()); 

    List<NameValuePair> params = new ArrayList<>(); 
    params.add(new BasicNameValuePair("task", "savemodel")); 
    String generatedJSONString = null; 
    params.add(new BasicNameValuePair("code", generatedJSONString)); 
    CloseableHttpResponse response = null; 
    Scanner in = null; 

    try { 
     post.setEntity(new UrlEncodedFormEntity(params)); 
     response = httpClient.execute(post); 
     HttpEntity entity = response.getEntity(); 
     in = new Scanner(entity.getContent()); 

     while (in.hasNext()) { 
      JsonString += in.next(); 

     } 

     EntityUtils.consume(entity); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
// System.out.println(JsonString); 

    JSONObject jsonObject = new JSONObject(JsonString); 
    JSONObject myResponse = jsonObject.getJSONObject("login"); 
    Object myResponse2 = myResponse.get("loginStatus"); 

的System.out.println（myResponse2）GET請求;

嘗試......

URL url = new URL("http://"...); 
HttpURLConnection http = (HttpURLConnection) 
url.openConnection(); 
http.setRequestMethod("GET"); 
http.setDoOutput(true); 
http.connect(); 

OutputStream out = http.getOutputStream(); 
OutputStreamWriter writer = new OutputStreamWriter(out); 
writer.write(FOO); 
writer.flush(); 
writer.close(); 

InputStreamReader in = new InputStreamReader(http.getInputStream()); 
BufferedReader br = new BufferedReader(in); 

char[] chars = new char[BUF_SIZE]; 
int size = br.read(chars); 

String response = new String(chars).substring(0, size); 

在try-catch塊全封閉式。
