【问题描述】：

所以我试图用 python 发送一封带有以下代码的基本电子邮件，但它给了我一个错误，提示我使用浏览器登录。我做到了，它仍然吐出同样的错误。代码：

import smtplib
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login("projtig6@gmail.com", "redacted")

msg = "Your security system has detected an intrusion of some kind please refere to http://projetotig6.orgfree.com/ for an image of the current situation"
server.sendmail("projtig6@gmail.com", "grenskul@gmail.com", msg)
server.quit()

当我运行它时它给了我这个

user@ubuntu:~/Desktop$ python3 tent.py
Traceback (most recent call last):
  File "tent.py", line 5, in <module>
    server.login("projtig6@gmail.com", "redacted")

忘了提到我已经关注了该页面上的所有内容。我激活了 POP 和 IMAP 。可以连接到不发送附件的 SMTP 服务器。我唯一可能导致错误的是 ssl/TSL 的事情，但我不明白，所以我在这里发布。
您确实意识到您正在公开显示您的密码...
这不是实际密码。即使是一次性邮件。

【解决方案1】：

首先，确保您“允许不太安全的应用通过您的 gmail 进行身份验证”：https://support.google.com/accounts/answer/6010255?hl=en

如果这不是问题，请尝试使用我在 python 中发送电子邮件时编写的这个包装器；它使发送电子邮件变得超级简单：https://github.com/krystofl/krystof-utils/blob/master/python/krystof_email_wrapper.py

像这样使用它：

emailer = Krystof_email_wrapper()

email_body = 'Hello, <br /><br />' \
             'This is the body of the email.'

emailer.create_email('sender@example.com', 'Sender Name',
                     ['recipient@example.com'],
                     email_body,
                     'Email subject!',
                     attachments = ['filename.txt'])

cred = { 'email': 'sender@example.com', 'password': 'VERYSECURE' }

emailer.send_email(login_dict = cred, force_send = True)

您还可以查看源代码以了解其工作原理。相关位：

import email
import smtplib   # sending of the emails
from email.mime.multipart   import MIMEMultipart
from email.mime.text        import MIMEText

self.msg = MIMEMultipart()

self.msg.preamble   = "This is a multi-part message in MIME format."

# set the sender
author = email.utils.formataddr((from_name, from_email))
self.msg['From'] = author

# set recipients (from list of email address strings)
self.msg['To' ] = ', '.join(to_emails)
self.msg['Cc' ] = ', '.join(cc_emails)
self.msg['Bcc'] = ', '.join(bcc_emails)

# set the subject
self.msg['Subject'] = subject

# set the body
msg_text = MIMEText(body.encode('utf-8'), 'html', _charset='utf-8')
self.msg.attach(msg_text)

# send the email
session = smtplib.SMTP('smtp.gmail.com', 587)
session.ehlo()
session.starttls()
session.login(login_dict['email'], login_dict['password'])
session.send_message(self.msg)
session.quit()
