잊어 버린 암호를 구현할 때 오류가 발생했습니다. ANDROID

Question

비밀번호를 잊어 버린 기능을 PHP 응용 프로그램에 구현하려고 시도했지만 오류가 발생했습니다. 나는 나의 PHP 파일이 전자 우편을 움켜 잡고 그 (것)들에게 보내도록 그 (것)들을 params에서 저장하는 그들의 전자 우편 aftermath를 위해 사용자를 요구한다. 다음은

내 코드입니다 :

여기

btnPasswordSubmit.setOnClickListener(new View.OnClickListener() { 

     public void onClick(View v) { 
      // new ForgotPassword().execute(); 
      String recoveryPassword = txtRecoveryPassword.getText() 
        .toString(); 

      // Building Parameters 
      List<NameValuePair> params = new ArrayList<NameValuePair>(); 
      params.add(new BasicNameValuePair("email", recoveryPassword)); 
      // getting JSON Object 
      // Note that create event URL accepts POST method 
      JSONObject json = jsonParser.makeHttpRequest(
        forgotPassword_url, "POST", params); 

      // check log cat for response 
      Log.d("Create Response", json.toString()); 

      // check for success tag 
      try { 
       int success = json.getInt(TAG_SUCCESS); 

       if (success == 1) { 
        // successfully email sent 
        Intent intent = new Intent(getApplicationContext(), 
          ForgotPasswordSuccessActivity.class); 
        startActivity(intent); 
        finish(); 
       } else { 
        // failed to create event 
       } 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 
     } 
    }); 

내 로그 캣입니다 :

Answer 1

당신이 빈 문자열이 테스트를하고 있습니까? logcat의이 줄을 기반으로합니다 :

08-22 16:32:58.904: E/JSON Parser(271): Error parsing data org.json.JSONException: End of input at character 0 of 

빈 문자열을 구문 분석하려고 시도하는 것 같습니다.
