Python Email 模块使用指南：发送、接收和解析电子邮件

在 Python 中，可以使用'email'模块来处理电子邮件。以下是一些'email'模块的常用方法和示例：

1. 创建一个简单的文本邮件：

import smtplib
from email.mime.text import MIMEText

msg = MIMEText('This is a test email.')
msg['Subject'] = 'Test Email'
msg['From'] = 'sender@example.com'
msg['To'] = 'recipient@example.com'

# 发送邮件
s = smtplib.SMTP('localhost')
s.send_message(msg)
s.quit()

2. 创建一个带附件的邮件：

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

msg = MIMEMultipart()
msg['Subject'] = 'Test Email with Attachment'
msg['From'] = 'sender@example.com'
msg['To'] = 'recipient@example.com'

# 添加文本内容
text = MIMEText('This is a test email with attachment.')
msg.attach(text)

# 添加图片附件
with open('image.jpg', 'rb') as f:
    image = MIMEImage(f.read())
    image.add_header('Content-Disposition', 'attachment', filename='image.jpg')
    msg.attach(image)

# 发送邮件
s = smtplib.SMTP('localhost')
s.send_message(msg)
s.quit()

3. 解析收到的邮件：

import imaplib
import email

# 连接到IMAP服务器
imap_server = imaplib.IMAP4('imap.example.com')
imap_server.login('username', 'password')
imap_server.select('INBOX')

# 搜索邮件
status, email_ids = imap_server.search(None, 'ALL')

# 获取邮件内容
for email_id in email_ids[0].split():
    status, email_data = imap_server.fetch(email_id, '(RFC822)')
    raw_email = email_data[0][1]
    email_message = email.message_from_bytes(raw_email)

    print(email_message['From'])
    print(email_message['Subject'])
    print(email_message.get_payload())

# 关闭IMAP连接
imap_server.close()
imap_server.logout()

这些示例只是'email'模块的一部分功能。要了解更多关于'email'模块的信息，可以查阅官方文档：https://docs.python.org/3/library/email.html
