POST yöntemi ve HttpURLConnection

Question

ile Android'den PHP sunucusuna bir JSON Nesnesi gönder Benim Android uygulaması ve yerel ağdaki WampServer'ım arasında iletişim kurmaya çalışıyorum.

Sunucudan veri okumak istediğimde başarı elde ettim, ancak sunucuya veri göndermeye çalışırken sorun yaşıyorum.

public class SynchronisationService extends Service { 
@Override 
public IBinder onBind(Intent intent) { 
    return null; 
} 

@Override 
public int onStartCommand(Intent intent, int flags, int startId) { 
    super.onStartCommand(intent, flags, startId); 

    new Thread(new Runnable() { 
     @Override 
     public void run() { 
      try { 
       URL url = new URL("http://192.168.37.23/happiness_barometer/php_input.php"); 
       HttpURLConnection connection = (HttpURLConnection) url.openConnection(); 
       connection.setDoOutput(true); 
       connection.setDoInput(false); 
       connection.setRequestMethod("POST"); 
       connection.connect(); 
       OutputStream outputStream = connection.getOutputStream(); 
       OutputStreamWriter writer = new OutputStreamWriter(outputStream); 
       JSONObject jsonObject = new JSONObject(); 
       jsonObject.put("rate", 1); 
       writer.write(URLEncoder.encode(jsonObject.toString(), "UTF-8")); 
       writer.flush(); 
       writer.close(); 

      } catch (Exception e) { 
       Log.v("EXCEPTION", e.getMessage()); 
      } 
     } 
    }).start(); 


    stopSelf(); 

    return flags; 
} 

}

Ve php dosyası::

Ben kurulan iletişimin bir hizmeti kullanıyorum Uygulamamı çalıştırdığınızda

<?php 

    try 
    { 
     $bdd = new PDO('mysql:host=localhost;dbname=happiness_barometer;charset=utf8', 'utilisateur', ''); 
    } catch (Exception $e) 
    { 
     die('Erreur : '.$e->getMessage()); 
    } 

    $sql = $bdd->prepare(
    'INSERT INTO rates (rate, comment, category, day, month, year, hour, minute, day_of_week, week, rate_number) 
    VALUES (:rate, :comment, :category, :day, :month, :year, :hour, :minute, :day_of_week, :week, :rate_number)'); 
    if (!empty($_POST['rate'])) { 
     $sql->execute(array(
      'rate' => $_POST['rate'], 
      'comment' => '', 
      'category' => 'pro', 
      'day' => 19, 
      'month' => 8, 
      'year' => 2015, 
      'hour' => 18, 
      'minute' => 3, 
      'day_of_week' =>3, 
      'week' => 33, 
      'rate_number' => 2)); 
    } 
?> 

, hiçbir şey eklenir benim veri tabanı. Sanırım $_POST['rate']'da hiçbir şey yok.

Lütfen kodumda neyin yanlış olduğunu söyle? Bu kod ile

Son olarak, başarı benim sunucuya JSONObject nesnesi göndermek için.

new Thread(new Runnable() { 
     @Override 
     public void run() { 
      OutputStream os = null; 
      InputStream is = null; 
      HttpURLConnection conn = null; 
      try { 
       //constants 
       URL url = new URL("http://192.168.43.64/happiness_barometer/php_input.php"); 
       JSONObject jsonObject = new JSONObject(); 
       jsonObject.put("rate", "1"); 
       jsonObject.put("comment", "OK"); 
       jsonObject.put("category", "pro"); 
       jsonObject.put("day", "19"); 
       jsonObject.put("month", "8"); 
       jsonObject.put("year", "2015"); 
       jsonObject.put("hour", "16"); 
       jsonObject.put("minute", "41"); 
       jsonObject.put("day_of_week", "3"); 
       jsonObject.put("week", "34"); 
       jsonObject.put("rate_number", "1"); 
       String message = jsonObject.toString(); 

       conn = (HttpURLConnection) url.openConnection(); 
       conn.setReadTimeout(10000 /*milliseconds*/); 
       conn.setConnectTimeout(15000 /* milliseconds */); 
       conn.setRequestMethod("POST"); 
       conn.setDoInput(true); 
       conn.setDoOutput(true); 
       conn.setFixedLengthStreamingMode(message.getBytes().length); 

       //make some HTTP header nicety 
       conn.setRequestProperty("Content-Type", "application/json;charset=utf-8"); 
       conn.setRequestProperty("X-Requested-With", "XMLHttpRequest"); 

       //open 
       conn.connect(); 

       //setup send 
       os = new BufferedOutputStream(conn.getOutputStream()); 
       os.write(message.getBytes()); 
       //clean up 
       os.flush(); 

       //do somehting with response 
       is = conn.getInputStream(); 
       //String contentAsString = readIt(is,len); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } finally { 
       //clean up 
       try { 
        os.close(); 
        is.close(); 
       } catch (IOException e) { 
        e.printStackTrace(); 
       } 

       conn.disconnect(); 
      } 
     } 
    }).start(); 

ve php kısmında bu bir:

Ben robot kısmı için bu kodu kullanılan

$json = file_get_contents('php://input'); 
$obj = json_decode($json); 
$rate = $obj->{'rate'}; 
$comment = $obj->{'comment'}; 
$category = $obj->{'category'}; 
$day = $obj->{'day'}; 
$month = $obj->{'month'}; 
$year = $obj->{'year'}; 
$hour = $obj->{'hour'}; 
$minute = $obj->{'minute'}; 
$day_of_week = $obj->{'day_of_week'}; 
$week = $obj->{'week'}; 
$rate_number = $obj->{'rate_number'}; 

try 
{ 
    $bdd = new PDO('mysql:host=localhost;dbname=happiness_barometer;charset=utf8', 'utilisateur', ''); 
} catch (Exception $e) 
{ 
    die('Erreur : '.$e->getMessage()); 
} 

$sql = $bdd->prepare(
'INSERT INTO rates (rate, comment, category, day, month, year, hour, minute, day_of_week, week, rate_number) 
VALUES (:rate, :comment, :category, :day, :month, :year, :hour, :minute, :day_of_week, :week, :rate_number)'); 
if (!empty($rate)) { 
    $sql->execute(array(
     'rate' => $rate, 
     'comment' => $comment, 
     'category' => $category, 
     'day' => $day, 
     'month' => $month, 
     'year' => $year, 
     'hour' => $hour, 
     'minute' => $minute, 
     'day_of_week' => $day_of_week, 
     'week' => $week, 
     'rate_number' => $rate_number)); 
}

Kontrol: PHP Side

public class UniversalNetworkConnection { 

    public static String postJSONObject(String myurl, JSONObject parameters) { 
     HttpURLConnection conn = null; 
     try { 
      StringBuffer response = null; 
      URL url = new URL(myurl); 
      conn = (HttpURLConnection) url.openConnection(); 
      conn.setReadTimeout(10000); 
      conn.setConnectTimeout(15000); 
      conn.setRequestProperty("Content-Type", "application/json"); 
      conn.setDoOutput(true); 
      conn.setRequestMethod("POST"); 
      OutputStream out = new BufferedOutputStream(conn.getOutputStream()); 
      BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, "UTF-8")); 
      writer.write(parameters.toString()); 
      writer.close(); 
      out.close(); 
      int responseCode = conn.getResponseCode(); 
      System.out.println("responseCode" + responseCode); 
      switch (responseCode) { 
       case 200: 
        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream())); 
        String inputLine; 
        response = new StringBuffer(); 
        while ((inputLine = in.readLine()) != null) { 
         response.append(inputLine); 
        } 
        in.close(); 
        return response.toString(); 
      } 
     } catch (IOException ex) { 
      ex.printStackTrace(); 
     } finally { 
      if (conn != null) { 
       try { 
        conn.disconnect(); 
       } catch (Exception ex) { 
        ex.printStackTrace(); 
       } 
      } 
     } 
     return null; 
    } 

} 

:

<?php 
    $json = file_get_contents('php://input'); 
    $obj = json_decode($json); 
    print_r($obj); 
    print_r("this is a test"); 
?>
