私は自分の問題についてグーグルで検索しましたが、何も見つかりませんでした。アンドロイドフォンからサーバーにファイルをアップロードするためにwin7でサーバーを作成しましたが、ファイルをアップロードできません。サーバーの設定/構成が正しいかわかりません！[server1] [1]

HttpURLConnection connection = null;
        DataOutputStream outputStream = null;
        DataInputStream inputStream = null;

        String pathToOurFile = "/sdcard/test.txt"; //complete path of file from your android device
        String urlServer = "http://www.rar.com/";// complete path of server
        String lineEnd = "\r\n";
        String twoHyphens = "--";
        String boundary = "*****";
        Log.i("*******urlServer**1**", "urlServer ");
        int bytesRead, bytesAvailable, bufferSize;
        byte[] buffer;
        int maxBufferSize = 1 * 1024 * 1024;

        try {
            FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile));
            Log.i("*******fileInputStream******", "sent: ");
            URL url = new URL(urlServer);
            connection = (HttpURLConnection) url.openConnection();
            Log.i("*******HttpURLConnection**1**", "v ");
            // Allow Inputs & Outputs
            connection.setDoInput(true);
            connection.setDoOutput(true);
            connection.setUseCaches(false);

            // Enable POST method
            connection.setRequestMethod("POST");

            connection.setRequestProperty("Connection", "Keep-Alive");
            connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
            Log.i("*******setRequestProperty**1**", "v ");
            outputStream = new DataOutputStream(connection.getOutputStream());
            Log.i("*******DataOutputStream******", "DataOutputStream: ");
            outputStream.writeBytes(twoHyphens + boundary + lineEnd);
            outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile + "\"" + lineEnd);
            outputStream.writeBytes(lineEnd);
            Log.i("*******lineEnd******", "writeBytes: ");
            bytesAvailable = fileInputStream.available();
            bufferSize = Math.min(bytesAvailable, maxBufferSize);
            buffer = new byte[bufferSize];

            // Read file
            bytesRead = fileInputStream.read(buffer, 0, bufferSize);
            Log.i("*******befwhile******", "byteread ");
            Log.i("*******byteread******", String.valueOf(bytesRead));

            while (bytesRead > 0) {
                outputStream.write(buffer, 0, bufferSize);
                bytesAvailable = fileInputStream.available();
                bufferSize = Math.min(bytesAvailable, maxBufferSize);
                bytesRead = fileInputStream.read(buffer, 0, bufferSize);
            }
            Log.i("*******befwhile******", "end while ");
            outputStream.writeBytes(lineEnd);
            outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
            Log.i("*******befwhile******", "twoHyphens ");
            // Responses from the server (code and message)
            int serverResponseCode = 0;
            String serverResponseMessage = "";
            serverResponseCode = connection.getResponseCode();
            Log.i("*******befwhile******", "getResponseCode1 ");
            serverResponseMessage = connection.getResponseMessage();
            Log.i("*******befwhile******", "getResponseMessage2 ");

            fileInputStream.close();
            outputStream.flush();
            outputStream.close();
            Log.i("*******Sending******", "sent: Final***");
        }
        catch (Exception ex) {
            Log.i("*******exception&&" + ex.toString(), ex.getMessage());
            //Exception handling
        }

また、outputStream.writeBytes（ "Content-Disposition：form-data; name = \" uploadedfile \ "; filename = \" "+ pathToOurFile +" \ "" + lineEnd）;の意味もありません。上記のコードを実行すると、Log.i（ " ** befwhile * "、 "twoHyphens"）;まで実行されます。私を助けてください！

ドキュメントから url.openConnection() は HttpURLConnection ではなく URLConnection を返すため、メソッド getResponseCode() は存在しません。HttpURLConnection へのダウンキャストは機能しません。また、すべてのデータはフラッシュ メソッドの後に送信されます。
