python - 如何在 Python 中连接到 FTP 服务器？

Question

当我尝试连接到 ftp 服务器时遇到问题，我使用的是带有 BigSur 和 Python3 的 Mac。

这是我的代码：

import ftplib

FTP_HOST = "ftp://myserver"
FTP_USER = "user"
FTP_PASS = "pass"

# connect to the FTP server
ftp = ftplib.FTP(FTP_HOST, FTP_USER, FTP_PASS)

它返回的内容如下：

Traceback (most recent call last):
  File "/Users/adrianrodriguezgalisteo/jonsuGo/test_upload.py", line 8, in <module>
    ftp = ftplib.FTP(FTP_HOST, FTP_USER, FTP_PASS)
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/ftplib.py", line 119, in __init__
    self.connect(host)
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/ftplib.py", line 156, in connect
    self.sock = socket.create_connection((self.host, self.port), self.timeout,
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/socket.py", line 822, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/socket.py", line 953, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 8] nodename nor servname provided, or not known

我只想连接到服务器并上传文件。

谢谢你。

https://docs.python.org/3/library/ftplib.html 主机只能是 myserver

FTP_HOST = "myserver"

您可能需要服务器名称的 FQDN
