在 HTML 电子邮件中使用变量？

Question

我正在使用在此 post Sending Email Using Python

上找到的信息

到目前为止，说明是完美的。我还有两件事想做：

在正文中调用一个变量
添加附件

变量将是今天的日期。就是这样：

today = datetime.datetime.today ()
tday = today.strftime ("%m-%d-%Y")

我知道使用 mailx，您可以使用 -a 选项附加。

Answer 1

对于您的第一个问题：有很多方法可以创建使用变量的字符串。

部分方式为：

body = "blablabla " + tday + " bloo bloo bloo"
body = "Today's date is {}, in case you wondered".format(tday)

对于你的第二个问题，你必须告诉我们你正在使用哪个库/模块，然后你可以转到该模块的文档页面，看看是否有添加附件的东西。

Answer 2

要调用html体内的变量，只需将它们转换为字符串以在体内连接它们

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

today = datetime.today ()
tday = today.strftime ("%m-%d-%Y")

# email subject, from , to will be defined here
msg = MIMEMultipart()

html = """\
<html>
  <head></head>
  <body>
    <p>Hi!<br>
       How are you?<br>
       """ +str(today)+ """ and """ +str(tday)+ """
    </p>
  </body>
</html>
"""
msg.attach(MIMEText(html, 'html'))

编辑： 上面提供的 link 似乎不可用，因此通过电子邮件（特别是来自 gmail）发送附件的代码片段如下

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders

msg = MIMEMultipart()

msg['From'] = "from email address"
msg['To'] = "to email address" 
msg['Subject'] = "Subject line" 
body = """Body 
          content"""

msg.attach(MIMEText(body, 'plain'))
attachment = open("/path/to/file", "rb") 
p = MIMEBase('application', 'octet-stream') 

# To change the payload into encoded form 
p.set_payload((attachment).read()) 

# encode into base64 
encoders.encode_base64(p) 

p.add_header('Content-Disposition', "attachment; filename= %s" % filename) 

# attach the instance 'p' to instance 'msg' 
msg.attach(p) 

s = smtplib.SMTP('smtp.gmail.com', 587) 
s.starttls() # for security
s.login("from email address", "your password") 

text = msg.as_string() 

# sending the mail 
s.sendmail("from email address", "to email address" , text)
s.quit()

注意：Google 有时会阻止来自其他应用程序（安全性较低的应用程序）的登录，因此需要在您的 Google 帐户设置中允许此访问 https://myaccount.google.com/u/1/lesssecureapps?pli=1&pageId=none

感谢大家发帖提示。

为了后代，这是工作脚本。

唯一剩下的项目是我需要能够将同一封电子邮件发送给多个人。

我尝试将所有电子邮件地址添加到变量中，中间用逗号分隔，但他们没有收到。当我查看收到的电子邮件时，它们似乎在“收件人”行中。是否可能只发送到列出的第一个电子邮件地址？

#!/usr/bin/python
import smtplib
import time
import datetime
from datetime import date
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEBase import MIMEBase
from email import encoders

fromaddr = "NOREPLY@test.com"
toaddr = ['me@test.com', 'thatguy@test.com']

#   Date
today = datetime.datetime.today ()
tday = today.strftime ("%m-%d-%Y")

msg = MIMEMultipart()

msg['From'] = fromaddr
msg['To'] = ", ".join(toaddr)
msg['Subject'] = "My Subject Goes Here"

body = """\
<html>
  <head></head>
  <body>
<p>DO NOT REPLY TO THIS EMAIL!!<br>
<br>
Script run for data as of """ + tday + """.<br>
<br>
See attachment for items to discuss<br>
<br>
The files have also been uploaded to <a href="http://testing.com/getit">SharePoint</a><br>
<br>
If you have any issues, email admin@test.com<br>
<br>
    </p>
  </body>
</html>
"""

msg.attach(MIMEText(body, 'html'))

filename = "discuss.csv"
attachment = open("discuss.csv", "rb")

part = MIMEBase('application', 'octet-stream')
part.set_payload((attachment).read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', "attachment; filename= %s" % filename)

msg.attach(part)

server = smtplib.SMTP('localhost')
text = msg.as_string()
server.sendmail(fromaddr, toaddr, text)
server.quit()
