本文详细介绍了如何使用Python的smtplib库通过SMTP协议发送纯文本、HTML格式邮件，并附带图片和文件附件。涵盖了登录邮箱、设置邮件内容、发送附件的基本步骤。

邮件自动发送的基本流程

# smtplib  - 登录邮箱；发送邮件
import smtplib
from email.mime.multipart import MIMEMultipart
from email.header import Header
from email.mime.text import MIMEText


# 第一步：登录邮箱
# 1. 连接邮箱服务器
# smtplib.SMTP_SSL(服务器地址, 邮箱服务端口)    -   连接邮箱服务器并且返回一个连接对象
connect = smtplib.SMTP_SSL('smtp.qq.com', 465)

# 2.登录邮箱
# 连接对象.login(账号, 密码)
connect.login('840792269@qq.com', '----------')

# 第二步：准备邮件
# 1. 创建邮件对象
email = MIMEMultipart()

# 2. 设置邮件主题
# Header(邮件标题, 编码方式)
email['Subject'] = Header('第一次发送邮件', 'utf-8').encode()

# 3. 设置邮件接受者信息（收件人）
email['To'] = '840792269dr@qq.com'

# 4. 设置邮件发件人
email['From'] = '840792269@qq.com <840792269@qq.com>'

# 5. 添加正文
"""
MIMEText(文字内容, 类型, 编码方式)
类型 - plain(普通文字)、html(超文本)
"""
text = MIMEText('你好吗？吃饭了吗?', 'plain', 'utf-8')
email.attach(text)

# 第三步：通过连接发送邮件
# 连接对象.sendmail(发件人, 收件人, 邮件对象.as_string())
connect.sendmail('840792269@qq.com', 'dr840792269', email.as_string())
connect.quit()    # 关闭连接

发送附件

import smtplib
from email.mime.multipart import MIMEMultipart
from email.header import Header
from email.mime.text import MIMEText
from email.mime.image import MIMEImage

# 1. 登录
connect = smtplib.SMTP_SSL('smtp.qq.com', 465)
connect.login('840792269@qq.com', '-----------------')

# 2. 准备邮件
email = MIMEMultipart()

email['Subject'] = Header('发送附件', 'utf-8').encode()
email['To'] = '840792269dr@163.com'
email['From'] = '840792269@qq.com <840792269@qq.com>'

text = MIMEText('文件在附件中，请注意查收!', 'plain', 'utf-8')
email.attach(text)

# ===================1. 图片附件=====================
# 1）打开图片读取图片二进制数据
image_data = open('files/luffy4.jpg', 'rb').read()
# 2）创建图片对象
image = MIMEImage(image_data)
# 3）设置图片为附件
image['Content-Disposition'] = 'attachment; filename="luffy.jpg"'
# 4）将图片附件添加到邮件对象中
email.attach(image)

# ==================2.其他文件附件====================
file_data1 = open('files/a.zip', 'rb').read()
file1 = MIMEText(file_data1, 'base64', 'utf-8')
file1['Content-Disposition'] = 'attachment; filename="a.zip"'
email.attach(file1)

file_data2 = open('files/服务能力提供规范.xlsx', 'rb').read()
file2 = MIMEText(file_data2, 'base64', 'utf-8')
file2['Content-Disposition'] = 'attachment; filename="data.xlsx"'
email.attach(file2)

# 3. 发送邮件
connect.sendmail('840792269@qq.com', 'dr840792269@163.com', email.as_string())
connect.quit()

超文本邮件内容

import smtplib
from email.mime.multipart import MIMEMultipart
from email.header import Header
from email.mime.text import MIMEText
from email.mime.image import MIMEImage

connect = smtplib.SMTP_SSL('smtp.qq.com', 465)
connect.login('840792269@qq.com', '----------------')

email = MIMEMultipart()
email['Subject'] = Header('HTML邮件', 'utf-8').encode()
email['To'] = 'dr840792269@163.com'
email['From'] = '840792269@qq.com <840792269@qq.com>'

# ========================邮件正文=====================
content = open('files/send.html', encoding='utf-8').read()
text = MIMEText(content, 'html', 'utf-8')
email.attach(text)


image_data = open('files/luffy4.jpg', 'rb').read()
image = MIMEImage(image_data)
image.add_header('Content-ID', '<image1>')	#  本地图片放在正文的必要步骤
email.attach(image)


connect.sendmail('840792269@qq.com', 'dr840792269@163.com', email.as_string())
connect.quit()

print('=============================================================')
