Python中的HTML消息[重复]答案

【问题标题】：HTML Message in Python [duplicate]Python中的HTML消息[重复]
【发布时间】：2020-10-12 02:20:02
【问题描述】：

我对 Python 还很陌生，试图帮助自动化工作中的一些事情。我正在尝试使用它在 Excel 电子表格中向过去三个月内与我们一起购买的客户列表发送消息。我有以下内容，但它目前以纯文本形式发送 html 消息。我之前已经设法让它正确发送 html 消息，但无法将使用 pandas 从 excel 中提取数据与发送 html 消息相结合。

非常感谢任何帮助。

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

your_name = "NAME"
your_email = "EMAIL"
your_password = "PASSWORD"


server = smtplib.SMTP('smtp.office365.com', 587)
server.starttls()
server.ehlo()
server.login(your_email, your_password)


email_list = pd.read_excel("python_test.xlsx")


all_names = email_list['Name']
all_emails = email_list['Email']

for idx in range(len(all_emails)):

    name = all_names[idx]
    email = all_emails[idx]
    subject = ‘Subject’


    message = MIMEMultipart('mixed')


    BODY = html = """\
    <html>
     Html message goes here 
    </html>
    """

    HTML_BODY = MIMEText(BODY, 'html')
    message.attach(HTML_BODY)

    full_email = ("From: {0} <{1}>\n"
                  "To: {2} <{3}>\n"
                  "Subject: {4}\n\n"
                  "{5}"
                  .format(your_name, your_email, name, email, subject, message,))

    try:
        server.sendmail(your_email, [email], full_email)
        print('Email to {} successfully sent!\n\n'.format(email))
    except Exception as e:
        print('Email to {} could not be sent :( because {}\n\n'.format(email, str(e)))

server.close()

【问题讨论】：

您没有收到错误消息吗？你有错误的字符 ” 最后 your_password = "PASSWORD”。甚至 Stackoverflow 也无法突出显示/着色代码，因为这个字符是错误的。
Python 应该有特殊的方法来附加 HTML 和纯文本。据我所知，HTML 是作为普通附件发送的，只有邮件客户端/prgrams 将其显示为 HTML。使用format() 放置它不是一个好主意 - 它必须在每个附件之前添加特殊标题，但使用format() 手动创建字符串可能你没有添加它。您可以将错误的邮件和正确创建的邮件保存在 .eml 中，然后比较两个版本中的内容 - 您会看到差异。
顺便说一句：现在您在subject = ‘Subject’ 中遇到了错误字符的问题。这是你的真实代码吗？它给出了错误，因为您再次有错误的字符。

# convert both parts to MIMEText objects and add them to the MIMEMultipart message
part1 = MIMEText(text, "plain")
part2 = MIMEText(html, "html")
message.attach(part1)
message.attach(part2)
# send your email
with smtplib.SMTP("smtp.mailtrap.io", 2525) as server:
    server.login(login, password)
    server.sendmail(
