sysproxy.py

'''Sets Windows' proxy configurations easily.
  This script allows user to update Windows proxy settings easily,
  by using predefined values assigned to proxies identified by
  keywords.
  Note that it'll also refresh your system to guarantee that all
  settings take effect.  Although in the tests it seemed unnecessary
  (Windows 8.1), it's considered just a guarantee.
  Of course, you must reload all pages after running this script, but
  the first thing you gotta do before running it is to setup the PROXIES
  variable, creating an ID for each proxy in your environment, so you
  can refer to it by using that ID as a parameter.
  The "default" and "off" words are reserved, one for your proxy default
  settings and the other to disable proxy --remember to set up the 
  "default" keyword properly.  Running this script without parameters
  will print the current proxy settings on screen.
  Usage examples:
  $ python winproxy.py
  $ python winproxy.py off
  $ python winproxy.py proxyid

上述代码中的 my_proxy 是我加入的代理设置。也是该代码唯一需要改动的地方。

在命令行使用 pyinstaller -F sysproxy.py 将这段代码打包为可执行的单个 EXE 程序。

然后在 dist 文件夹下找到 sysproxy.exe

把这个 sysproxy.exe 放到已被配置好环境变量的目录下

使用：

sysproxy.exe off 关闭系统代理。

sysproxy.exe my_proxy 开启代理，并使用配置 my_proxy

可以在 cmd 下，Win+R 下执行。

省去了，开启代理时每次要 系统设置 → 网络 → 代理 → 开启代理 → 点击保存 ，以及关闭代理时要 系统设置 → 网络 → 代理 → 关闭代理 的繁琐步骤。
