Android POST httpsurlconnection

Question

HttpsUrlConnectionによるPOSTリクエストの送信に問題があります。私がDataOutputStreamを使用しないときは、すべてが瞬時にうまくいきます。その後、アプリはログに書き込まれません。私は問題がPOSTのためのデータを作成するか、または接続のために、またはデータを送信するために必要なプロパティの設定にあると思います。私のクラスは、私はあなたがdataOutputStremが必要だと思ういけないこの

のように見えます。代わりに、データの書き込みにOutputStreamWriterを使用する必要があります。
これがあなたの問題を解決することを願っています。

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);
