python – socket.gaierror：[Errno 11001] getaddrinfo失败

我试图使用
python将文件附加到邮件.

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失败

完整的错误消息：

 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

最佳答案 问题是“smtp服务器名称”的DNS查找失败 – 如果这是您的确切代码,那么您可以看到原因 – 如果没有,并且您具有SMTP服务器的有效限定名称,那么您可能遇到防火墙问题/互联网连接等,也必须将端口设置为有效值以匹配您的服务器SMTP配置(通常是端口25但不是绝对总是).
