Question

出于某种原因，我的FTP服务器代码只允许我传输小文件。有谁知道我的代码可能出错？ Part of Server Code Here

private void Retr(String filename) {

    OutputStream output = null;

    sendOut("150 Preparando-se para tranferir arquivo");

    try {

        output = this.dataSocket.getOutputStream();
        File file = new File(this.fileManager.getPath() + File.separator
                + filename);

        System.out.println(file.getAbsolutePath());
        RandomAccessFile reader = new RandomAccessFile(file, "rw");
        byte[] fileBytes = new byte[1024];
        System.out.println(file.getAbsolutePath());
        while (reader.getFilePointer() < reader.length())
            output.write(fileBytes, 0, reader.read(fileBytes));

        output.flush();
        output.close();

        sendOut("226 transferencia de " + filename + " concluída");

    } catch (IOException e) {

        e.printStackTrace();
    }
}
