有人可以告诉我为什么我从下面的代码中收到SMTPServerDisconnected(“连接意外关闭”)错误吗?

import smtplib

from string import Template

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

MY_ADDRESS = '---'
PASSWORD = '---'

def get_contacts(filename):
"""
Return two lists names, emails containing names and email 
addresses
read from a file specified by filename.
"""

names = []
emails = []
with open(filename, mode='r', encoding='utf-8') as contacts_file:
    for a_contact in contacts_file:
        names.append(a_contact.split()[0])
        emails.append(a_contact.split()[1])
return names, emails

def read_template(filename):
"""
Returns a Template object comprising the contents of the 
file specified by filename.
"""

with open(filename, 'r', encoding='utf-8') as template_file:
    template_file_content = template_file.read()
return Template(template_file_content)

def main():
names, emails = get_contacts('contacts.txt') # read contacts
message_template = read_template('message.txt')

# set up the SMTP server
s = smtplib.SMTP('smtp.gmail.com', 465)
s.ehlo()
s.starttls()
s.login(MY_ADDRESS, PASSWORD)

# For each contact, send the email:
for name, email in zip(names, emails):
    msg = MIMEMultipart()       # create a message

    # add in the actual person name to the message template
    message = 
message_template.substitute(PERSON_NAME=name.title())

    # Prints out the message body for our sake
    print(message)

    # setup the parameters of the message
    msg['From']=MY_ADDRESS
    msg['To']=email
    msg['Subject']="This is TEST"

    # add in the message body
    msg.attach(MIMEText(message, 'plain'))

    # send the message via the server set up earlier.
    s.send_message(msg)
    del msg

# Terminate the SMTP session and close the connection
s.quit()

if __name__ == '__main__':
main()

很明显,当我运行代码时,我的地址和密码已填写。

在终端中运行时得到的回溯是:

回溯(最近通话最近):   在第71行中输入文件“ emailAlert2.py”     主要()   主文件“ emailAlert2.py”,第40行     s = smtplib.SMTP('smtp.gmail.com',465)    init 中的文件“ /usr/local/Cellar/python/3.7.5/Frameworks/Python.framework/Versions/3.7/lib/python3.7/smtplib.py”,第251行     (代码,信息)= self.connect(主机,端口)   在连接中的文件“ /usr/local/Cellar/python/3.7.5/Frameworks/Python.framework/Versions/3.7/lib/python3.7/smtplib.py”中,行338     (代码,味精)= self.getreply()   在getreply中的文件“ /usr/local/Cellar/python/3.7.5/Frameworks/Python.framework/Versions/3.7/lib/python3.7/smtplib.py”,行394     引发SMTPServerDisconnected(“连接意外关闭”) smtplib.SMTPServerDisconnected:连接意外关闭

谢谢

Google Gmail服务器正在挂断您的电话(放弃连接尝试)。

如果您已启用对Gmail帐户的第三方访问(link),请按以下步骤更改代码:

s = smtplib.SMTP('smtp.gmail.com', 465)
s.ehlo()
s.starttls()
s.login(MY_ADDRESS, PASSWORD)

更改为此:

s = smtplib.SMTP_SSL('smtp.gmail.com', 465)
s.ehlo()
s.login(MY_ADDRESS, PASSWORD)

挂断的原因是您正在使用未加密的方法(smtplib.SMTP())创建连接。 Google希望您使用需要SSL的SMTPS进行连接。

尝试使用端口号 587 代替s = smtplib.SMTP('smtp.gmail.com', 465)

中的端口 465

可能您需要提供应用密码而不是默认密码 - 看看这个 - https://support.google.com/accounts/answer/185833
