使用Python发送邮件
之前写了一个小工具从远程服务器下载文件，然后通过附件方式发送给自己的邮箱，中间用到了Python里跟邮件相关的两个标准库email和smtp，使用也并不复杂。
import smtplib
import ssl
from email import encoders
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from typing import List, Tuple
from app.settings import config
context = ssl.create_default_context() # 初始化ssl上下文
def make_message(sender_email: str, receiver_email: str, subject: str,
content: str,
attachments: List[Tuple[str, bytes]]) -> MIMEBase:
message = MIMEMultipart() # 创建一个Message对象并设置邮件的基本信息
message['From'] = sender_email
message['To'] = receiver_email
message['Subject'] = subject
message['Bcc'] = receiver_email
message.attach(MIMEText(content, 'plain'))
for name, binary_content in attachments: # 添加附件
attachment = MIMEBase("application", "octet-stream")
attachment.set_payload(binary_content)
encoders.encode_base64(attachment)
attachment.add_header(
"Content-Disposition",
f"attachment; filename= {name}",
)
message.attach(attachment)
return message
def send_email(receiver_email: str, subject: str, content: str,
attachments: List[Tuple[str, bytes]]):
with smtplib.SMTP_SSL(config.host, config.port, context=context) as server: # 配置smtp发送服务器
sender_email, password = config.email, config.password
server.login(sender_email, password) # 登录邮箱账户
message = make_message(sender_email, receiver_email, subject, content,
attachments)
server.send_message(message, sender_email, receiver_email)
