Suggest give an api to get url

[lijiarui]

hi
I want to get url in Message, I print message and find url in Message.rawOby.Url. But i can't use m.rawObj.Url to get Url

than I use (m.rawObj as any).Url to get Url

I suggest you can give an api for us to get Url if you have time.

thanks!

there is no plan to create a api for Url now, because this is only for the specific message type. maybe consider it in the future when we create a new message class for it.

detail suggestion and discussion is welcome. thanks.
