python实现每天定时发送邮件的流程步骤

目录

• 步骤 1: 安装所需的库
• 步骤 2: 编写发送电子邮件的 Python 脚本
• 步骤 3: 配置电子邮件发送服务
• 步骤 4: 运行脚本
• 进一步扩展
• 补充知识：Python定时自动发送邮件
• 1、Python代码
• 2、定时调度-使用Linux中的crontab
• (1) 进入编辑页面
• (2) 编写定时调度语句
• (3) 重启crontab 使调度配置生效
• (4) 观察调度进度
• (5) 查看调度执行日志

    # 邮件正文内容
    body = "这是您的每日报告。"
    msg.attach(MIMEText(body, 'plain'))

    # 登录到邮件服务器并发送邮件
    try:

        server.sendmail(sender_email, receiver_email, text)
        print("邮件发送成功")
    except Exception as e:
        print(f"邮件发送失败: {e}")
    finally:
        server.quit()

# 设置每天固定时间发送邮件
schedule.every().day.at("08:00").do(send_email)

# 保持脚本运行，检查任务调度
while True:
    schedule.run_pending()
    time.sleep(60)  # 每隔一分钟检查一次任务
