У меня есть приложение Java, использующее Apache Commons Net для загрузки mp3 на мой FTP-сервер.
Однако, если это новый файл, он выдаст MalformedServerReplyException. Если это существующий файл, он будет отлично загружен и перезаписан.
Исключение уже выдано в строке:
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
Однако я проверил в Wireshark, и команда TYPE I работает нормально.
Может ли кто-нибудь помочь мне с этим?
Вот изображение Wireshark вплоть до исключения:
public static void transferFile(File file, boolean OverwriteAllowed) {
FtpLogin();
try {
System.out.println('\n');
System.out.println("DEBUG: "+ file.toString());
boolean isNewFile = false;
String filePath = getFtpPathToMusic() + file.getName();
ftpClient.sendNoOp();
showServerReply();
if (ftpClient.listFiles(filePath).length > 0) {
System.out.println("File exists, and overwrite allowed is: " + OverwriteAllowed);
} else {
isNewFile = true;
// System.out.println("File does not exist yet on server");
}
if (OverwriteAllowed || isNewFile) {
ftpClient.setStrictReplyParsing(false);
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
showServerReply();
InputStream inputStream = new FileInputStream(file);
OutputStream outputStream = ftpClient.storeFileStream(filePath);
byte[] bytesIn = new byte[4096];
int read;
long remaining = file.length();
long transferred = 0;
System.out.println("Transfering data...");
while ((read = inputStream.read(bytesIn)) != -1) {
outputStream.write(bytesIn, 0, read);
remaining -= read;
transferred += read;
System.out.print('\r');
System.out.print("Remaining: " + remaining/1024 + "kb | Transferred: " + transferred/1024 + "kb");
}
System.out.println();
inputStream.close();
outputStream.close();
boolean completed = ftpClient.completePendingCommand();
if (completed) {
showServerReply();
System.out.println("File " + filePath + " uploaded succesfully");
}
} else {
System.out.println("File is skipped");
}
} catch (IOException e) {
e.printStackTrace();
showServerReply();
}
}
Ожидается: успешная загрузка
