使用 Python 访问 FTP 服务器失败并显示“getaddrinfo"；错误

I am trying to access the open DLP Test FTP server as a practice. I keep getting a getaddrinfo error but I am unsure of where I'm going wrong. I am using Python 2 on a Windows 10, and have already checked that I am not behind a proxy.

代码:

from ftplib import FTP
ftp = FTP('ftp://ftp.dlptest.com/')
...

错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:Python27libftplib.py", line 120, in __init__
    self.connect(host)
  File "C:Python27libftplib.py", line 135, in connect
    self.sock = socket.create_connection((self.host, self.port), self.timeout)
  File "C:Python27libsocket.py", line 553, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno 11001] getaddrinfo failed

感谢任何帮助！

解决方案

使用

ftp = FTP('ftp.dlptest.com')

改为.

FTP 构造函数的第一个参数 是 host - 主机名 或 IP 地址 - 不是 URL.
