java http请求 返回结果是json ，转成对象使用

 URLConnection connection = null;
        try {
            connection = new URL("地址...").openConnection();
            connection.connect();

 

            InputStream fin = connection.getInputStream();
            BufferedReader br = new BufferedReader(new InputStreamReader(fin));
            StringBuffer buffer = new StringBuffer();
            String temp = null;
            while ((temp = br.readLine()) != null) {
                buffer.append(temp);
            }
            JSONArray ct = new JSONArray(buffer.toString());

 

            for (int i = 0; i < ct.length(); i++) {
                JSONObject obj = ct.getJSONObject(i);
                obj.get("key");//key...
            }

 

        } catch (IOException e) {
            e.printStackTrace();
        } catch (JSONException e) {
            e.printStackTrace();
        }
