Python ftplib 在 FTP 期间失败

Question

问题：我需要打开从 python 脚本到 android ftp-服务器的 ftp 连接.我收到以下错误：

ConnectionResetError: [Errno 104] Connection reset by peer

错误堆栈跟踪在底部给出。

这是我的 Python 脚本：

import ftplib
try:
      logger.info(ftp_ip+ftp_port)
      FTP=ftplib.FTP()
      ftp_msg=FTP.connect(host=ftp_ip, port=2221)
      logger.info("Message: "+ftp_msg)
      ftp_msg=FTP.login(user=ftp_username, passwd=ftp_pwd)
      logger.info("Message: "+ftp_msg)
      ftp_msg=FTP.pwd()
      logger.info("Current dir: "+ftp_msg)
      filename = '/....xml'
      with open(filename, 'rb') as fp:
       res = FTP.storbinary("STOR " + filename, fp)
except ftplib.all_errors as e:
      logger.error('FTP error:', e)

我正在为 python FTP 使用 "ftplib" 库。

堆栈跟踪和日志：

  File "/usr/lib/python3.5/ftplib.py", line 508, in storbinary
    conn.sendall(buf)
ConnectionResetError: [Errno 104] Connection reset by peer

During handling of the above exception, another exception occurred:

  File "/usr/lib/python3.5/logging/__init__.py", line 981, in emit
    msg = self.format(record)

    return fmt.format(record)

    record.message = record.getMessage()

Message: 'FTP error:'
Arguments: (ConnectionResetError(104, 'Connection reset by peer'),)

所以当它建立连接时，打印当前目录但无法上传文件。失败的原因是什么？

Answer 1

可能是因为本地目录路径错误。我用了

 os.chdir("/home/pi/../.../.../")

在 FTP 转移之前，它就像一个魅力。给出 full/absolute 路径不是解决方案。
