主要涉及subprocess的使用,简单点,直接上代码吧,只是做一下记录。

  # 功能:文件上传、代码提交、执行代码、停止代码

  #

  # 路由:ip:8000/

  # 演示功能:打开上传文件或者上传文件的浏览器界面,点及上传或者提交代码

  # 路由:ip:8000/upload

  # post上传文件的接口,将所选的文件中的内容转储到服务器中的/tmp/new_code.py文件中

  # 路由:ip:8000/send

  # post提交代码的接口,代码作为字符串形式提交

  # 路由:ip:8000/run/start

  # 启动服务器中文件名为new_code.py的代码文件,新建线程执行

  # 路由:ip:8000/run/stop

  # 停止服务器中文件名为new_code.py所开启的线程

  ##

  # 设置服务的端口

  define("port", default=8000, type=int, help="run server on the given port.")

  # 静态资源配置
