java - 将 InputStream 转换为 JSONObject

Question

我正在使用以下代码将 InputStream 转换为 JSONObject。我的问题是，有什么简单的方法可以将 InputStream 转换为 JSONObject。不做 InputStream -> BufferedReader -> StringBuilder -> 循环 -> JSONObject.toString()。

    InputStream inputStreamObject = PositionKeeperRequestTest.class.getResourceAsStream(jsonFileName);
    BufferedReader streamReader = new BufferedReader(new InputStreamReader(inputStreamObject, "UTF-8"));
    StringBuilder responseStrBuilder = new StringBuilder();

    String inputStr;
    while ((inputStr = streamReader.readLine()) != null)
        responseStrBuilder.append(inputStr);

    JSONObject jsonObject = new JSONObject(responseStrBuilder.toString());

由于您已经在使用 Google 的 Json-Simple 库，您可以像这样从 InputStream 解析 json:

InputStream inputStream = ... //Read from a file, or a HttpRequest, or whatever.
JSONParser jsonParser = new JSONParser();
JSONObject jsonObject = (JSONObject)jsonParser.parse(
      new InputStreamReader(inputStream, "UTF-8"));
