1.1. Preface
I wrote a simple automated ticket purchase program for 2023 12306. This part is to solve the problem of sending notifications after successful ticket purchase. The content of the notifications is simple Chinese sentences, so you can just learn to send simple emails without in-depth understanding of the protocols used. The specific process of sending and receiving;

3. Steps
3.1. Open QQ mailbox SMTP
Note: The account that sends emails only needs to enable this service, and the service that receives emails does not need to be enabled.
1) Log in to your QQ mailbox on the computer and click Settings after logging in.
As shown in Figure 1 below:

3) Scroll down to find the service to open and verify according to the prompts.
As shown in Figure 3 below
Tips: After the verification is completed, there will be a key, which needs to be remembered;

4. Code
4.1. Complete source code
What is implemented here is that one of our mailboxes sends a ticket purchase success prompt message to another mailbox (the other mailbox can be any mailbox). Here, the QQ mailbox is used to send it to another QQ mailbox.
import smtplib # 导入协议
from email.mime.text import MIMEText # 导入发送包装
from email.header import Header # 标题包
send_addr = "发送人邮箱"
receive_addr = "接收人邮箱"
key = "验证成功出现的密钥" # 密钥
text = "成功抢到票，请前往购票平台付款！" # 发送信息正文内容
smtp_addr = "smtp.qq.com"
msg = MIMEText(text, 'plain', 'utf-8')
msg["From"] = send_addr # 发送地址
msg["To"] = receive_addr # 接收地址
msg["Subject"] = Header(text, 'utf-8') # 标题
server = smtplib.SMTP_SSL(smtp_addr, 465) # url和端口
server.login(send_addr, key) # 登录邮箱
server.sendmail(send_addr, receive_addr, msg.as_string()) # 发送方、接收方、发送信息格式等
server.quit() # 退出5. Results
