需求分析
groupUsers
---- get : 获取指定组下的user列表
-----create：网用户组添加用户
-----delete：从组中删除用户GET: /api/groupUser/1
POST: r = request.post(“http://192.168.33.10:8080/groupUsers/”,data=json) 【data={‘uid’:1,’gid’:1}】
DELETE: r = request.delete(“http://192.168.33.10:8080/groupUsers/”,data=json) 【data={‘uid’:1,’gid’:1}】 #走界面不行
