Python ftplib - specify port
提问by
I would like to specify the port with Python's ftplib client (instead of default port 21).
我想用 Python 的 ftplib 客户端指定端口（而不是默认端口 21）。
Here is the code:
这是代码：
from ftplib import FTP
ftp = FTP('localhost') # connect to host, default port
Is there an easy way to specify an alternative port?
有没有一种简单的方法来指定替代端口？

>>> from ftplib import FTP
>>> HOST = "localhost"
>>> PORT = 12345 # Set your desired port number
>>> ftp = FTP()
>>> ftp.connect(HOST, PORT)

Found the answer. Instantiate the FTP object and then run connect on it like so:
找到了答案。实例化 FTP 对象，然后像这样在其上运行连接：
from ftplib import FTP
ftp = FTP()
ftp.connect('localhost', 2121)

After searching numerous solutions, a combination of the docs.python.organd the connectcommand solved my issue.
在搜索了许多解决方案后，docs.python.org和connect命令的组合解决了我的问题。
from ftplib import FTP_TLS
host = 'host'
port = 12345
usr = 'user'
pwd = 'password'
ftps = FTP_TLS()
ftps.connect(host, port)
# Output: '220 Server ready for new user.'
ftps.login(usr, pwd)
# Output: '230 User usr logged in.'
ftps.prot_p()
# Output: '200 PROT command successful.'
ftp.nlst()
# Output: ['mysubdirectory', 'mydoc']
If you're using plain FTP instead of FTPS, just use ftplib.FTPinstead.
如果您使用的是普通 FTP 而不是 FTPS，请ftplib.FTP改用。
