消息接口功能

外部向茶余群组发送消息需要遵循http协议，"GroupId"、"Token"为头部必备字段, Token为该群组的认证码，该接口当前仅支持文字消息，body不宜过大。

协议格式如下:

					
						POST /sendGroupMsg HTTP/1.1
						GroupId:10002083
						Token:eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJncm91cF9pZCI6IjEwMDAyMDgzIiwiaWF0IjoxNjU4OTcxOTU2LCJpc3MiOiJjaGF5dSJ9.Du-QGhCM6v6HW602di2PMBKZnNwmCeXHryLa2Vx0JUE
