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消息。 我究竟做错了什么？ 该站点的用户指南给出了使用您的电子邮件地址作为密码以“匿名”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

我没有和您一样的错误，但是，FTP不支持URL作为定义远程FTP服务器的一种方式。 相反，它需要一个主机名或IP地址：

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