请问有办法取得个人和群的唯一标识吗？或者有没有办法自己构建？

如题，应用场景比如需要保存聊天记录。

You can get the unique ID for a contact/room by contact.id and room.id. However, this id will not keep consistent across Web Sessions.

If you want to identify the same contact across web sessions, you need to set a remark for the contact, like: contact.remark('1'), then you can expect to get 1 for the same contact by call contact.remark().

For a room, I still have no idea of how to identify it right now, because web wechat has no "remark for the room" feature yet. If anyone has any good idea or suggestion, please let me know, will appreciate it.

One more thing, there's looks have a way to get the Uin for a contact & a room from this issue: #90 . But we still did not have time to figure out how it works. If you could help us to figure it out, we can add this feature to Wechaty.
