将字符串转换成JSONObject的

更新时间：2023-02-03 08:59:21

尝试DIS希望它会为ü工作

 公共类TestObjectToJson {
      公众诠释K1 = 1;
      公共字符串K2 =测试;      公共静态无效的主要（字串[] args）{
          TestObjectToJson的obj =新TestObjectToJson（）;
          GSON GSON =新GSON（）;
    JSON字符串= gson.toJson（OBJ）;          的System.out.println（JSON）;
      }    }

有关引用u能看到这种

I'm just going to get right into it. I get an error in LogCat that says my JSON String can not be converted into a JSONOject and I really don't know how to work my around this error so I was just hoping somebody with better knowledge than me can give me advice on how I can attend to this issue

Logcat:

08-02 00:12:28.485: E/JSON Parser(778): Error parsing data org.json.JSONException: Value <!doctype of type java.lang.String cannot be converted to JSONObject

JSONParser class

 public class JSONParser {

    InputStream is;
    JSONObject jObj;
    String json = "";
    public EditText et;

    public JSONParser () {
    }

    public JSONObject readJSONFeed(String URL) {

        try{
        HttpClient client = new DefaultHttpClient();
        HttpPost request = new HttpPost(URL);
        //request.setURI(website);
        try {
            HttpResponse response = client.execute(request);
        HttpEntity httpEntity = response.getEntity();
        is = httpEntity.getContent();

        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            json = sb.toString();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }

        try {
            jObj = new JSONObject(json);
        } catch (JSONException e) {
           Log.e("JSON Parser", "Error parsing data " + e.toString());
        }

        return jObj;

        }finally{}

    }{
    }}

This is the method that is causing this error to appear:

    try {
        jObj = new JSONObject(json);
    } catch (JSONException e) {
       Log.e("JSON Parser", "Error parsing data " + e.toString());
    }

I've printed my JSON String:

Try dis hope it will work for u

 public class TestObjectToJson {
      public int k1 = 1;
      public String k2 = "Test";

      public static void main(String[] args) {
          TestObjectToJson obj = new TestObjectToJson();
          Gson gson = new Gson();
    String json = gson.toJson(obj);

          System.out.println(json);
      }

    }
