登録ページデータストアがJSONエンコードが受信されていません

Question

私はそれがちょっとした問題だと確信していますが、変更が必要なのはわかりません：私のアプリには登録ページがあります。ユーザーがデータを挿入すると、データはPHPスクリプトに渡され、MYSQLデータベースに保存されます。接続はdbで新しいユーザーを取得するときに機能しますが、json $の成功は機能しません。ユーザーを登録できる場合はToastを作成して新しいアクティビティに変更したいが、ボタン。

は、ここに私のJavaコードです：

        return; 
       } 
      } 

      class AsyncDataClass extends AsyncTask<String, Void, String> { 
       @Override 
       protected String doInBackground(String... params) {

         httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
         HttpResponse response = httpClient.execute(httpPost); 
         jsonResult = inputStreamToString(response.getEntity().getContent()).toString(); 
        } catch (ClientProtocolException e) { 
         e.printStackTrace(); 
        } catch (IOException e) { 
         e.printStackTrace(); 
        } 
        return jsonResult; 
       } 

       @Override 
       protected void onPreExecute() { 
        super.onPreExecute(); 
       } 

       @Override 
       protected void onPostExecute(String result) { 
        super.onPostExecute(result); 

        int jsonResult = returnParsedJsonObject(result); 
        if (jsonResult == 0) { 
         Toast.makeText(JetztRegistrieren.this, "Passwörter stimmen nicht überein", Toast.LENGTH_LONG).show(); 
         return; 
        } 
        if (jsonResult == 1) { 
         Intent intent = new Intent(JetztRegistrieren.this, Startseite.class); 
         Toast.makeText(JetztRegistrieren.this, "Willkommen bei Stage Driver! Jetzt loslegen.", Toast.LENGTH_LONG).show(); 
         startActivity(intent); 
         return; 
        } 
        System.out.println("Resulted Value: " + result); 
       } 

       private StringBuilder inputStreamToString(InputStream is) { 
        String rLine = ""; 
        StringBuilder answer = new StringBuilder(); 
        BufferedReader br = new BufferedReader(new InputStreamReader(is)); 
        try { 
         while ((rLine = br.readLine()) != null) { 
          answer.append(rLine); 
         } 
        } catch (IOException e) { 
         e.printStackTrace(); 
        }

       private int returnParsedJsonObject(String result) { 
        JSONObject resultObject = null; 
        int returnedResult = 2; 
        try { 
         resultObject = new JSONObject(result); 
         returnedResult = resultObject.getInt("success"); 
        } catch (JSONException e) { 
         e.printStackTrace(); 
        } 
        return returnedResult; 
       } 
      }); 
     } 
    } 

そして、これはPHPのファイルです：事前に

<?php 
include('config.php'); 
session_start(); 

$name = $_POST["enteredname"]; 
$pass = $_POST["enteredpassword"]; 
$pass2 = $_POST["enteredpassword2"]; 
$email = $_POST["enteredemail"]; 
$tel = $_POST["enteredTelnr"]; 
$geb = $_POST["enteredGeb"]; 
$gender = $_POST["userGender"]; 

if($pass != $pass2) { 
    $success = 0; 
} 
else { 
    $hash = md5($pass); 
    $speichern = "INSERT INTO user (user_name, user_pw, user_mail, user_tel, user_geb, user_geschl) 
        VALUES('$name', '$hash', '$email', '$tel', '$geb', '$gender');"; 
    mysql_query($speichern) or die(mysql_error()); 
    if($speichern) { 
     $success = 1; 
    } 
} 
echo json_encode($success); 
?> 

ありがとう！

Answer 1

問題は、返すコンテンツタイプにHTTPヘッダーを返さないことです。

PHPスクリプトの先頭にこれを追加します。

header("Content-Type: application/json;charset=utf-8"); 

Answer 2

だから私はそれをするJsonResultは、PHPスクリプトに私は$成功を書いたので、それはだ、変換できないと言うログに、私は、エラーを見つけたと思います= 0;代わりに$ response ["success"] = 0のようなものでなければならないと思います。
