试试这个：

   @Override
        protected void onPostExecute(String s) {
            if (s != null) {
                Log.e("Fetch_frame_response", s);
                try {
                    JSONObject object=new JSONObject(s);
                    String userToken=object.getString("authenticationToken");
                    Log.e("userToken",userToken);
                } catch (JSONException e) {
                    e.printStackTrace();
                }  
                Intent abc = new Intent(MainActivity.this, Orderlist.class);
                startActivity(abc);
                finish();
            } else {
                Intent abc = new Intent(MainActivity.this, MainActivity.class);
                startActivity(abc);
                Toast.makeText(MainActivity.this, "Invalid credentials", Toast.LENGTH_LONG).show();
            }
        }
    }
}

在你发布后

你必须解析你的json不要使用substring

    @Override
    protected void onPostExecute(String s) {
        if (s != null) {

             try {
                        JSONObject responseObject = new JSONObject(s);
                        int status = responseObject.getInt("status");
                        String message =responseObject.getString("message");
                        if(status == 1){
                        String UserToken =   responseObject.getString("userToken");         
 Log.i("userToken",UserToken );    
 Intent abc = new Intent(MainActivity.this, Orderlist.class);
 abc.putExtra("userToken",UserToken);
            startActivity(abc);
            finish();                 
                                 Toast.makeText(context,message,Toast.LENGTH_LONG).show();
                        }else if(status ==2){
                               Toast.makeText(context,message,Toast.LENGTH_LONG).show();
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }


        } else {
            Intent abc = new Intent(MainActivity.this, MainActivity.class);
            startActivity(abc);
            Toast.makeText(MainActivity.this, "Invalid credentials", Toast.LENGTH_LONG).show();
        }
    }
}
}
