我如何将数据传递给artifact？

Not to push my luck, but if I could also get the user id and topic id in the artifact, that would open up a lot more applications.

topic id is easy to add, but user id can get a tiny bit more tricky, cause the artifact is heavily cached, we would have to reduce some of the caching to make that happen.
