完整步骤

1、epel 源安装 python3

准备一台能 24h 运行的服务器，首先安装 epel 源：

yum install -y epel-release

查询yum的python3状况：

Repository epel is listed more than once in the configuration
abrt-addon-python3.noarch                 2.1.11-50.el7                epel     
boost-python36.x86_64                     1.53.0-30.el7                epel     
boost-python36-devel.x86_64               1.53.0-30.el7                epel     
boost-python36-static.x86_64              1.53.0-30.el7                epel     
boost169-mpich-python3.x86_64             1.69.0-2.el7                 epel     
boost169-mpich-python3-devel.x86_64       1.69.0-2.el7                 epel 

我们看到，可以安装 python3，python34，python36。那么我以安装python36为例子，下面是安装python36和其对应pip的脚本：

yum install -y python36 python36-pip

安装好之后就可以直接使用，运行 python3 或者 python36 或者 python3.6 命令即可，库安装则使用的是 pip3 或者 pip3.6 命令。

2、安装依赖的库

pip3 install requests

3、自动打卡代码

根据不同用户，你需要修改的地方包括：

• 你学校的打卡 url
• 你的浏览器 cookie 复制过来（登陆一下打卡页面，然后F12去看cookie）
• new_body 变量对应的请求体，你得抓一下提交打卡信息的时候的 post 请求体，把里面的参数复制过来
• 你的邮箱地址。根据SMTP协议，qq邮箱发送邮件需要授权码，操作方法在网上搜索就行

（已经将代码中包含的定位信息、cookie、邮箱等做了处理，非真实信息）

        ret = False
        print(e)
    return ret


ret = mail()

if ret:
    print("邮件发送成功")
else:
    print("邮件发送失败")

4、设置 cron 定时任务

我把上面这个 main.py 放在 /usr/local/testPy 目录了，然后开一个 cron 定时任务：

# 设置定时任务，vim打开
crontab -e

# 设置每天00：01分执行一次，> /dev/null 2>&1目的在于拒收程序指定时间执行后系统自动寄送的信件
# */1 * * * * python3 /usr/local/testPy/main.py      # 示例，每隔一分钟执行一次
1 0 * * * python3 /usr/local/testPy/main.py -> /dev/null 2>&1

# 几个常用命令
tail -f /var/log/cron # 实时监控 cron 日志输出

改成每分钟执行，测试一下效果

最后提示：请大家遵守防疫管控的各项规定，配合并听从各项措施和要求~
