Python v3.4.3 ftp 连接被拒绝

Question

我正在尝试从 ftp 服务器下载文件，但无法连接。这是代码框架和错误信息。我究竟做错了什么？该站点的用户指南提供了使用您的电子邮件地址作为密码以 "anonymous" 身份登录的说明。

server = "ftp://ftp.sec.gov/"
directory = "edgar/data/"
filename = "nameoffile.txt"

from ftplib import FTP
ftp = FTP(server, 'anonymous', 'myemail@gmail.com') #Set server address

然后弹出：

Traceback (most recent call last):
  File "<pyshell#19>", line 1, in <module>
ftp = FTP(server)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/ftplib.py", line 118, in __init__
self.connect(host)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/ftplib.py", line 153, in connect
source_address=self.source_address)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/socket.py", line 512, in create_connection
raise err
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/socket.py", line 503, in create_connection
sock.connect(sa)
ConnectionRefusedError: [Errno 61] Connection refused

我没有遇到与您相同的错误，但是，FTP 不支持将 URL 作为定义远程 FTP 服务器的方式。相反，它需要主机名或 IP 地址：

>>> from ftplib import FTP
>>> ftp = FTP('ftp.sec.gov', 'anonymous', 'myemail@gmail.com')
>>> ftp.dir()
