Question

我有json文件，我从互联网上下来并保存到我的应用程序。然后我读取此文件并创建json对象。但我无法创建json对象。这是我得到的例外

org.json.JSONException：{\＆＃34; resources \＆＃34;：{..........

的字符3处的预期文字值

下面是我读取输入流和创建json对象的代码

 private JSONObject readFileFromInpputStream(InputStream inst) throws JSONException
    {
        // TODO Auto-generated method stub
        StringBuilder responseStrBuilder=null;
        try { 
            BufferedReader streamReader = new BufferedReader(new InputStreamReader(inst, "UTF-8")); 
            responseStrBuilder = new StringBuilder();

            String inputStr;
            while ((inputStr = streamReader.readLine()) != null){
                responseStrBuilder.append(inputStr);  
            }
        }
        catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        String str = responseStrBuilder.toString();
        String k=str.replace("\"", "\\\"");
       // String m =k.replaceAll("\t", "");
       // String s= m.replaceAll("\n", "");
        //String p = s.replaceAll("\\s", "");
        Log.i(loggerName, loggerName + " str " +str);
        //Log.i(loggerName, loggerName + " k " +p);
        JSONObject obj = new JSONObject(k);
        return obj;
    }

下面是输出字符串

以下是我得到的例外

org.json.JSONException: Expected literal value at character 3 of {  \"resources\": { ..........

我做错了什么？

Answer 1

没有理由逃避引号（＆＃34;）。它们是json对象构造函数如何识别字符串的一部分。

只需使用

JSONObject obj = new JSONObject(str);

应该没问题。

此外，

in＆＃34;组合视图（％s）＆＃34;这两个引号被视为字符串分隔符，应该被转义，但它表明您收到此消息的服务器存在问题。自己逃避这些是不可能的，因为没有确定的方法可以知道哪些引号是真实的，哪些是文本的一部分。

Answer 2

在通过Jlint验证您的JSON输出时，它会给出验证错误，但是在删除输出第2行的空间时（是故意的空间？还是在发布问题时添加了它？）

 "cdata", "value": "Text

]]>" }, { "nam

验证成功。

在任何情况下，空格是否是错误的初始来源，如CurlyCorvus所说，只需将字符串传递给new JSONObject(str);而不转义"。

Answer 3

Thans Mustafa和Curly。

问题是由于标记中的引号原来一个值的前者是 “价值”：“％1 $ s直到假期”

当我将其替换为时，它工作正常 “价值”：“％1 $ s直到假期”

所以我猜当里面有引号时会把它当作新对象。

JSON对象创建失败
