Question

当我手动尝试使用具有相同凭据的ftp时，我可以成功复制文件。但是，当尝试使用任何ftplib FTP命令时，出现连接重置错误...任何人都知道为什么？过程如下。

Python代码：

from ftplib import FTP
ftp = FTP('10.10.10.10')
ftp.set_debuglevel(5)
ftp.set_pasv('false') #false by default
ftp.login('user','pass')
ftp.dir()
ftp.close()

调试级别为5的日志：

python3 ftp.py
*get* '230 Login successful.\n'
*resp* '230 Login successful.'
*cmd* 'TYPE A'
*put* 'TYPE A\r\n'
*get* '200 Switching to ASCII mode.\n'
*resp* '200 Switching to ASCII mode.'
*cmd* 'PASV'
*put* 'PASV\r\n'

下面是Windows ftp输出。
