无法将此字符串转换为JSON

Question

我正在尝试将以下字符串转换为JSONArray。

 try {
        BufferedReader inputReader = new BufferedReader(new InputStreamReader(
                openFileInput(mFileName), "UTF-8"));
        String inputString;
        StringBuffer stringBuffer = new StringBuffer();
        while ((inputString = inputReader.readLine()) != null) {
            stringBuffer.append(inputString + "\n");
        }

        JSONArray JArray = new JSONArray(stringBuffer.toString());
        for(int i = 0; i < JArray.length() + 1; i++) {
            JSONObject obj = JArray.getJSONObject(i);
            mWrite = mWrite + obj.toString() + ",";

        }

问题是我收到此错误：

有人知道这里会发生什么吗？ 我是JSON的新手。

Answer 1

JSON的根是对象，而不是数组。 尝试这个：

JSONArray JArray = new JSONObject(stringBuffer.toString()).getJSONArray("friends");

Answer 2

我在Google Play中可用的查看器（JOE-JSON对象资源管理器）中打开了字符串。 它显示了包含数组的根对象好友。 如果您不熟悉JSON，JOE可能会帮助您更好地理解。
