在python中发送电子邮件（MIMEmultipart）

问题描述 投票：1回答：2

我应该如何在同一个机构中发送包含文本格式和html格式的电子邮件？ MIMEmultipart有什么用？

MIMEMultipart([MIMEText(msg, 'text'),MIMEtext(html,'html')])

我能够收到一封电子邮件，但身体空白

PS：我正在尝试发送文本并在同一个正文中附上一张桌子。我不想把表作为附件发送。

html = """
  <html>
   <head>
    <style> 
     table, th, td {{ border: 1px solid black; border-collapse: collapse; }} th, td {{ padding: 5px; }}
    </style>
   </head>
   <body><p>Hello, Friend This data is from a data frame.</p>
    <p>Here is your data:</p>
    {table}
    <p>Regards,</p>
    <p>Me</p>
   </body>
  </html> """

text = """
Hello, Friend.

Here is your data:

{table}

您需要将消息创建为

MIMEMultiPart('alternative')

然后附上两个MIMEText部分。

>>> text = 'Hello World'
>>> html = '<p>Hello World</p>'

>>> msg = MIMEMultipart('alternative')
>>> msg['Subject'] = 'Hello'
>>> msg['To'] = '[email protected]'
>>> msg['From'] = '[email protected]'

>>> msg.attach(MIMEText(text, 'plain'))
>>> msg.attach(MIMEText(html, 'html'))

>>> s.sendmail('[email protected]', '[email protected]', msg.as_string())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 's' is not defined
>>> s = smtplib.SMTP('localhost:1025')
>>> s.sendmail('[email protected]', '[email protected]', msg.as_string())

重新设计的电子邮件包（Python 3.6+）可用于发送相同的消息，如下所示：

>>> from email.message import EmailMessage
>>> msg = EmailMessage()
>>> msg['Subject'] = 'Hello'
>>> msg['To'] = '[email protected]'
>>> msg['From'] = '[email protected]'
>>> msg.set_content(text)
>>> msg.add_alternative(html, subtype='html')
>>> s.send_message(msg)

输出：

在'与'：

def temp_message(filename): 
   with open(filename,'r') as fl1:
      l2=fl1.read()

将其更改为：

def temp_message(filename):
   filename = temp_message('temp1.txt') #changed tmp1 to filename
   with open(filename, 'w+', encoding='utf-8') as fl1:
      fl1.write(text)
      fl1.write(html)
      fl1.write(regards)

您可以拆分文本变量的“问候”部分，以便您的html（表格）可以在两者之间。我很困惑你的问题是什么（很多编辑）但是如果我没弄错你的fl1（tempt1.txt）没有任何数据你只是'读'（r）文本文件但是没有什么都写不出来。我还建议您将'tmp1 = temp_message（'temp1.txt'）'放在'def temp_message（filename）'中以避免混淆。
