使用python从档案发送HTMLbody-编程知识-白鹭情

我可以发送纯文本，但无法发送 html 格式的 html 文本。

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

body = """
this is first mail by using python
"""
port_email = 587
smtp_server = "smtp.gmail.com"
password = "your password"


subject = "An email with attachment from Python"
sender_email = "sender@gmail.example.com"
receiver_email = "receiver@example.net"

# Create a multipart message and set headers
message = MIMEMultipart()
message["From"] = sender_email
message["To"] = receiver_email
message["Subject"] = subject
message["Bcc"] = receiver_email  # Recommended for mass emails

# Add body to email
message.attach(MIMEText(body, "plain"))
filename = "file name"  # In same directory as script

with open(filename.html, 'r', encoding="utf-8") as attachment:
    part1 = attachment.read()

part2 = MIMEText(part1, "html")
message.attach(part2)
text = message.as_string()

context = ssl.create_default_context()
with smtplib.SMTP_SSL(smtp_server, 465 , context=context) as server:
    server.login(sender_email, password)
    server.sendmail(sender_email, receiver_email, text)

这将发送附件，但我想在电子邮件正文中查看 html 文本。文件名是内容 html 表，因此代码应发送 html 文本，该文本将自动在带有 html 表的 html 正文中可用。

Mime 有多种格式。默认情况下MIMEMultipart构建多部分/混合讯息，这意味着一个简单的文本正文和一堆附件。

当您想要正文的 HTML 表示时，您需要多部分/替代讯息：

...
message = MIMEMultipart('alternative')
...

但是您使用的是旧的 compat32 API。从 Python 3.6 开始，您最好使用email.message.EmailMessage...

如果这不是你想要的，你为什么要传递一个假的身体？

您的代码似乎是为 Python 3.5 或更早版本撰写的。该email库在 3.6 中进行了大修，现在更加通用和合乎逻辑。可能会扔掉你所拥有的，然后从档案中的示例重新开始。email

这是一个简短的尝试。

from email.message import EmailMessage

... 
message = EmailMessage()
message["From"] = sender_email
message["To"] = receiver_email
message["Subject"] = subject
# No point in using Bcc if the recipient is already in To:

with open(filename) as fp:
    message.set_content(fp.read(), 'html')

# no need for a context if you are just using the default SSL
with smtplib.SMTP_SSL(smtp_server, 465) as server:
    server.login(sender_email, password)
    # Prefer the modern send_message method
    server.send_message(message)
