用户登录少不了密码，上一篇只用nickname进行验证。这一篇加上使用md5加密的password作为另一个条件进行登录验证。
需求
- 通过nickname和password(md5加密后)进行验证登录，查询数据库user表验证nickname和password
-
- 存在nickname并且password解密后与数据数据对应成功则生成token返回
- 反之返回{code:400,msg:'登录失败'}
- 为了方便操作，加入了一个字符串md5加密的接口（user/getMd5/:data）
-
- 传入字符串返回md5加密的密文字符串
环境
- 数据库（mysql）
-
- 数据库名称（database）：test，用户名（user）：root，密码（password）：123456
- 数据库user表做了一些改变，新加一个password字段
- 依赖包（package.json）
-
- 确保安装以下依赖包

自测
- 花名（nickname）和密码（password）登录
- 为了方便开发，临时加入获取md5数据加密的接口
- 通过id查询user，需要传token
- 查询所有user,不用传token
