如何在安卓工作室中使用 u0423 代码解析 json 对象

Question

我不知道如何解析它。

{

  "code": 1000,

  "result_msg": "Successful",

  "result": "{\"birthDateAsText\":\"1999-12-3100:00:00.0\",\"birthPlace\":\"\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423,\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\",\"civilId\":\"123\",\"firstname\":\"\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\",\"gender\":\"\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\",\"lastname\":\"\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\\u0423\",\"nationality\":\"\\u0423\\u0423\\u0423\\u0423\"}"

}

我试过这个

 if (resultObject.getInt("code") == 1000) {

   JSONParse jsonParse = new JSONParse();

   JSONObject object = resultObject.getJSONObject("result");

   event.onSuccess(jsonParse.convertJson(object));

   }

实际上，我不知道如何解析和解码 json 对象。请帮帮我

试试这个：private static String decodeUnicode(String theString) {&nbsp; &nbsp; char aChar;&nbsp; &nbsp; int len = theString.length();&nbsp; &nbsp; StringBuffer outBuffer = new StringBuffer(len);&nbsp; &nbsp; for (int x = 0; x < len;) {&nbsp; &nbsp; &nbsp; &nbsp; aChar = theString.charAt(x++);&nbsp; &nbsp; &nbsp; &nbsp; if (aChar == '\\') {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; aChar = theString.charAt(x++);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (aChar == 'u') {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Read the xxxx&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; int value = 0;&nbsp;

使用 UTF-8 解码您的响应&nbsp;try {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;resp = new String(Base64.decode(response.getBytes("UTF-8"), Base64.NO_WRAP), "UTF-8");&nbsp; &nbsp; &nbsp; &nbsp; } catch (UnsupportedEncodingException e) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Suppress exception (unlikely to happen in prod)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; PbLogger.e("Encoding exception", "");&nbsp; &nbsp; &nbsp; &nbsp; }
