requests登录网易云音乐并签到

登录主要参考https://www.cnblogs.com/zhuchunyu/p/10978093.html以及https://www.zhihu.com/question/36081767

通过观察发现网易云音乐不同的请求其参数加密方法是不变的，只是加密的内容不同

登录页的加密内容是

{"phone": username,
"password": password,
"rememberLogin": "true",
"checkToken": "",
"csrf_token": ""}

而签到页的加密内容是 {"type":1} 

如果要每天自动签到的话可以创建一个任务来运行脚本，不同的操作系统创建方法不同，这里不做讨论
