JSONP- Java String kann nicht in JSONObject (Android) umgewandelt werden

Question

Das ist mein Code:

String json = request.excutePost("http://192.168.1.42:3000/login_client",urlParameters); 
JSONObject jsonObj = new JSONObject(json); 

Die Logcat mir den nächsten Fehler angezeigt:

org.json.JSONException: Value {"login_client":"NEW_PASSWORD","token":"2de374f454699aa6fe895c56bc3a111b33f28b72888aec1f5faa77977e232828"} of type java.lang.String cannot be converted to JSONObject

, dass die executePost Funktion ist:

public String excutePost(String targetURL, String urlParameters) { 
    HttpURLConnection connection = null; 
    try { 

     //Create connection 
     URL url = new URL(targetURL); 
     connection = (HttpURLConnection)url.openConnection(); 
     connection.setRequestMethod("POST"); 
     connection.setRequestProperty("Content-Type", 
       "application/x-www-form-urlencoded"); 

     connection.setRequestProperty("Content-Length", 
       Integer.toString(urlParameters.getBytes().length)); 
     connection.setRequestProperty("Content-Language", "en-US"); 

     connection.setUseCaches(false); 
     connection.setDoOutput(true); 

     //Send request 
     DataOutputStream wr = new DataOutputStream (
       connection.getOutputStream()); 
     wr.writeBytes(urlParameters); 
     wr.close(); 
     //Get Response 
     InputStream is = connection.getInputStream(); 
     BufferedReader rd = new BufferedReader(new InputStreamReader(is)); 
     StringBuilder response = new StringBuilder(); // or StringBuffer if not Java 5+ 
     String line; 

     while((line = rd.readLine()) != null) 
     { 
      response.append(line); 
      response.append('\r'); 
     } 
     rd.close(); 
     //respuesta = response.toString().replaceAll("\"",); 
     Log.e("RESPONSE",response.toString()); 
     return response.toString(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
     return null; 
    } finally { 
     if(connection != null) { 
      connection.disconnect(); 
     } 
    } 
} 

Answer 1

Ihr Problem ist, dass Ihre Zeichenfolge h wie nicht gut formatiert um zu konvertieren. es sollte etwas, was so aussehen:

"{\"login_client\":\"NEW_PASSWORD\",\"token\":\"2de374f454699aa6fe895c56bc3a111b33f28b72888aec1f5faa77977e232828\"} " 

den Code versuchen Gebrüll:

import org.json.simple.JSONObject 

String json = request.excutePost("http://192.168.1.42:3000/login_client",urlParameters); 
JSONObject obj = new JSONParser().parse(json).getAsJsonObject();

Answer 2

String json = new String(request.excutePost("http://192.168.1.42:3000/login_client",urlParameters)); 
Log.e("Response",""+json);
