Android POST httpsurlconnection

Question

J'ai un problème avec envoyer une requête POST par HttpsUrlConnection. Tout va bien au moment où je n'utilise pas DataOutputStream. Après cela, l'application n'écrit pas dans le journal. Je suppose que ce problème est dans la création de données pour le POST ou dans les paramètres des propriétés requises pour la connexion ou dans la méthode d'envoi de données. Ma classe ressemble à ceci

public class Connection extends AsyncTask<String, Void, Object> { 

private List<String> cookies = new ArrayList<String>(); 

@Override 
protected Object doInBackground(String... strings) { 
    Log.d("Background", "working in background"); 
    CookieHandler.setDefault(new CookieManager()); 
    String result = ""; 
    String urlParameters = "formname="+FORMNAME+"&default_fun="+DEFAULT_FUN+"&userid="+strings[1]+"&password="+strings[2]; 
    byte[] postData = urlParameters.getBytes(Charset.forName("UTF-8")); 
    try { 
     result = getPageContent(strings[0]); 
     getsid(result); 
     Log.d("sid", sid); 
     Log.d("urlParameters", urlParameters); 
     sendPost(strings[0]+"index.php?"+sid, postData); 
     result = getPageContent(strings[0]+"logged_inc.php?"+sid+"&t=6799847"); 
     Log.d("After post", result); 
    }catch(Exception e) { 

    } 

    return null; 
} 

private String getPageContent(String page) throws Exception{ 
    String result = ""; 
    Log.d("getPageContent ", page); 
    URL url = new URL(page); 
    HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); 

    trustEveryone(); 
    conn.setSSLSocketFactory(sc.getSocketFactory()); 
    Log.d("result", result); 
    conn.setRequestMethod("GET"); 
    conn.setRequestProperty("Connection", CONNECTION); 
    conn.setRequestProperty("Content-Type", CONTENT_TYPE); 
    conn.setRequestProperty("User-Agent",USER_AGENT); 
    conn.connect(); 
    result = readContent(conn.getInputStream()); 


    return result; 
} 
private static void sendPost(String page, byte[] postData) throws Exception { 

    Log.d("postPageContent ", page); 
    URL url; 
    int postLength = postData.length; 
    HttpsURLConnection urlConnection = null; 
    url = new URL(page); 
    urlConnection = (HttpsURLConnection) url.openConnection(); 
    trustEveryone(); 

    urlConnection.setSSLSocketFactory(sc.getSocketFactory()); 
    urlConnection.setUseCaches(false); 
    urlConnection.setRequestMethod("POST"); 
    urlConnection.setRequestProperty("User-agent", "Mozilla/5.0"); 
    urlConnection.setRequestProperty("HOST", "host.com"); 
    urlConnection.setRequestProperty("Connection", "keep-alive"); 
    urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 

    urlConnection.setDoOutput(true); 
    urlConnection.setDoInput(true); 
    urlConnection.connect(); 
    int responseCode = urlConnection.getResponseCode(); 
    Log.d("response code", responseCode+""); 
    // Send post request 
    DataOutputStream wr = new DataOutputStream(urlConnection.getOutputStream()); 
    wr.write(postData); 
    wr.flush(); 
    wr.close(); 
} 

private void getsid(String html) {...} 

private static void trustEveryone() { 

    TrustManager[] trustAllCerts = new TrustManager[]{ 
      new X509TrustManager() { 
       public java.security.cert.X509Certificate[] getAcceptedIssuers() {return null;} 
       public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {}; 
       public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {}; 
      } 
    }; 

    try { 
     sc = SSLContext.getInstance("SSL"); 
     sc.init(null, trustAllCerts, new java.security.SecureRandom()); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 
private static String readContent(InputStream is) throws Exception{...} 

}

Je ne pense pas que vous avez besoin dataOutputStrem. Au lieu de cela, vous devez utiliser OutputStreamWriter pour écrire les données.
Espérons que cela résout votre problème.

URL url = new URL(Url+"ApiController"); 
     HttpURLConnection client = (HttpURLConnection) url.openConnection(); 
     client.setRequestMethod("POST"); 
     client.setRequestProperty("Content-Type", "application/json"); 
     client.setRequestProperty("Authorization", 
       "Basic xxxxxxxx"); 

     client.setDoOutput(true); 
     OutputStreamWriter wr = new OutputStreamWriter(client.getOutputStream()); 
     String data = "2"; 
     wr.write(data); 
     wr.flush(); 

     // Get the server response 

     BufferedReader reader = new BufferedReader(new InputStreamReader(client.getInputStream())); 
     StringBuilder sb = new StringBuilder(); 
     String line = null; 

     // Read Server Response 
     while((line = reader.readLine()) != null) 
     { 
      // Append server response in string 
      sb.append(line + "\n"); 
     } 

     String result = sb.toString(); 
     array = new JSONArray(result);
