java - Proftpd - 上传后的 0kb 文件

Question

我找了很久也没找到解决办法。 我正在尝试将文件从我的计算机上传到我的 ftp 服务器。但每次我尝试时，我都只创建一个 0kb 文件。

我已经尝试过

1. 关闭防火墙
2. 在文件夹上执行 chmod -R 775
3. 20 个不同版本的客户端
4. 被动传输模式
5. 二进制文件类型
6. 二进制类型传输模式
7. 使用最新的 commons-net 库 (3.3)

FTP a file to server, but it the result arrives with zero byte size

public static void goforIt(){
    FTPClient ftpClient = new FTPClient();
    ftpClient.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out)));
    try {

        ftpClient.connect("xxx.xxx.xxx.xx");

        ftpClient.login("xx", "xx");
        ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
        //ftpClient.setFileTransferMode(FTP.BINARY_FILE_TYPE);
        ftpClient.enterLocalPassiveMode();
        boolean w = ftpClient.changeWorkingDirectory("/var/www/xx");


        if (ftpClient.getReplyString().contains("250")) {
            InputStream in = null;
            try{
                in = new FileInputStream(new File("xx.mp4"));
            }catch (Exception e){
                e.printStackTrace();
                return;
            }

            ftpClient.sendCommand("PWD");


            boolean result = ftpClient.storeFile("/var/www/public_videos/xx.mp4", in);
            System.out.println(ftpClient.getReplyString() + result);

            in.close();
            ftpClient.logout();
            ftpClient.disconnect();
        }

    } catch (SocketException e) {
        e.printStackTrace();
    } catch (UnknownHostException e) {
         e.printStackTrace();
    } catch (IOException e) {
         e.printStackTrace();
    }
}

日志:

USER xx
331 Password required for xx
PASS xx
230 User xx logged in

250 CWD command successful
