python - socket.gaierror : [Errno 11001] getaddrinfo failed

Question

我尝试使用 python 将文件附加到邮件中。
代码:

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from smtplib import SMTPException


def send_Email():
    file1="abc.txt"
    message = "Test mail"
    msg = MIMEMultipart()

    msg.attach(MIMEText(file(file1).read()))

    try:
        smtpObj = smtplib.SMTP('smtp server name',port)
        smtpObj.sendmail(sender, EmailId, message, msg.as_string() )
        print "Successfully sent email"
    except SMTPException:
        print "Error: unable to send email"

Bt 我收到错误:socket.gaierror: [Errno 11001] getaddrinfo failed

完整的错误信息:

 File "C:\Python27\lib\smtplib.py", line 249, in __init__
    (code, msg) = self.connect(host, port)
  File "C:\Python27\lib\smtplib.py", line 309, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "C:\Python27\lib\smtplib.py", line 284, in _get_socket
    return socket.create_connection((port, host), timeout)
  File "C:\Python27\lib\socket.py", line 553, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno 11001] getaddrinfo failed

我确信当您从代理后面工作时会出现 gaierror。
