At present, the callback information of customer group change events is limited, only know which group has changed. As for the operation such as whether there is a new person joining the group or dissolving the group, it is suggested that the callback information be more abundant

收到群回调之后, 可以调用企业微信接口获取群当前的所有成员, 再和数据表已存的成员相比较, 这样就可以知道是哪一个成员入群,哪一个成员退群了, 虽然繁琐了一些,但也是无奈之举.
