Java实现CURL，与把字符串结果写到json文件

@Override

            e.printStackTrace();
        }
        //
        assert pro != null;
        BufferedReader br = new BufferedReader(new InputStreamReader(pro.getInputStream()), 4096);
        String line = null;
        int i = 0;
        //先读取每行的数据
        while (true) {
            try {
                if (!((line = br.readLine()) != null)) break;
            } catch (IOException e) {
                e.printStackTrace();
            }
            if (0 != i)
                sb.append("\r\n");
            i++;
            sb.append(line);
        }
//        System.out.println(sb.toString());
//       return JSON.parseObject(sb.toString());
        //调用接口，然后写到文件里

        } catch (IOException e) {
            e.printStackTrace();
        }
        return sb.toString();
    }
