Android アプリケーションから、Web サービスを呼び出してデータを取得する必要があります。その Web サービスを呼び出すには、HttpPostエンティティを使用します。

問題は、次のエラーが発生することです。

エラーは、この行の次のメソッドにあります。

response = client.execute(post);


public boolean sendJsonauthRegisterSession(JSONObject json, String url) {

    HttpParams httpParameters = new BasicHttpParams();
    int timeoutConnection = 150000;
    HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection); 
    int timeoutSocket = 150000;
    HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
    DefaultHttpClient client = new DefaultHttpClient(httpParameters);

    HttpResponse response;
    try {
        HttpPost post = new HttpPost(url);
        JSONObject js = new JSONObject();
        js.put("request_object", json);

        StringEntity se = new StringEntity(js.toString());
        se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE,
                "application/json"));
        post.setEntity(se);
        response = client.execute(post);

        /* Checking response */
        if (response != null) {
                    ...
        }
     } 
      catch(UnknownHostException e5){
          e5.printStackTrace();           
          this.callRegister="register_failed";
     } 
      catch(SocketException ex) {
          ex.printStackTrace();
          this.callRegister="register_failed";
     } 
      catch (Exception e) {
          e.printStackTrace();
          this.callRegister="register_failed";
     }

    client.getConnectionManager().shutdown();
    return registersession;
}

メソッドは から呼び出されAsyncTaskます。

私が間違っていることについて何か考えている人はいますか？ありがとうございました！！！

重要サーバーへの接続は 3G、EDGE で行われるため、非常に低速です。

接続を切断しているのはサーバーだけです。

この質問から抽出

それはかなり致命的です。リモート サーバーから RST パケットが送信されました。これは、通常のハンドシェイクではなく、接続がすぐに切断されたことを示しています。これにより、通常のハーフクローズ状態への移行がバイパスされます。私はこの説明が好きです：

「ピアによる接続のリセット」は、TCP/IP で電話をバタンと閉めることに相当します。単に返事をせず、ぶら下げたままにしておくよりも礼儀正しいです。しかし、これは真に礼儀正しい TCP/IP コンバーサーに期待される FIN-ACK ではありません。
