python - 尝试连接时出现 SMTP python 跟踪错误

Question

所以我收到此错误:

import smtplib
server = smtplib.SMTP()
server.connect()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/smtplib.py", line 309, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "/usr/lib/python2.7/smtplib.py", line 284, in _get_socket
   return socket.create_connection((port, host), timeout)
  File "/usr/lib/python2.7/socket.py", line 571, in create_connection
    raise err
socket.error: [Errno 111] Connection refused

不完全确定为什么:s有人可以帮我一下吗？

Answer 1

您正在尝试连接“localhost”，端口 25(.connect() 的默认值)，并且没有服务器在监听。因此连接被拒绝。
