我正在使用以下方法将文件从远程服务器 FTP 到本地机器。如果登录时的服务器没有输入参数，这可以正常工作。但是我有这个服务器，在我登录后我必须输入 1 并输入它才能进入主页。因此，当我在服务器上运行此代码时，默认情况下它会转到主页而不是工作目录。我怎样才能做到这一点？我的方法；：

public void FtpFiles() {
        try {

            //new ftp client
            FTPClient ftp = new FTPClient();
            //try to connect
            ftp.connect("FtpServerName");
            //login to server
            if (!ftp.login("serverusername", "serverpassword")) {
                ftp.logout();
            }
            int reply = ftp.getReplyCode();
            //FTPReply stores a set of constants for FTP reply codes. 
            if (!FTPReply.isPositiveCompletion(reply)) {
                ftp.disconnect();
            }
            //enter passive mode
            ftp.enterLocalPassiveMode();

            //get system name
            System.out.println("Remote system is " + ftp.getSystemType());
            //change current directory
            ftp.changeWorkingDirectory("/ftadm/home/users/Statements/testStatements");
            System.out.println("Current Statement directory is " + ftp.printWorkingDirectory());

            //get list of filenames
            FTPFile[] ftpFiles = ftp.listFiles();
            if (ftpFiles != null && ftpFiles.length > 0) {
                //loop thru files
                for (FTPFile file : ftpFiles) {
                    if (!file.isFile()) {
                        continue;
                    }
                    System.out.println("Moving File File " + file.getName());
                    //get output stream
                    OutputStream output;
                    output = new FileOutputStream(pr.getHomeDirName() + file.getName());
                    //get the file from the remote system
                    ftp.retrieveFile(file.getName(), output);
                    //close output stream
                    output.close();
                    //delete the file
                    if (pr.deleteRemoteFiles() == true) {            
                        ftp.deleteFile(file.getName());
                    }
                }
            }else{
                System.out.println("Remote Directory is Empty");
            }
            ftp.logout();
            ftp.disconnect();
        } catch (Exception asd) {
            System.out.println(asd.getMessage());
        }
    }

我正在使用 Apache FTP 客户端 API
