Baidu http tile url

[wttttt-wang]

Hi, thanks for this useful project. I am curious about how the baidu https tile urls are found? I have tried to search before, but nothing found. And is this url(https://gss{s}.bdstatic.com/8bo_dTSlRsgBo1vgoIiO_jowehsv/tile/?qt=tile&x={x}&y={y}&z={z}&styles=pl&scaler=1&udt=20170927) reliable?

Thanks for issue.

The url is from official support of baidu map, so I think it should be reliable.
But a fallback backup in production won't be hurt.

Thanks for reply.
What does udt=20170927 means? Is there other available https urls that I can take as a backup?
And you said this is from baidu map official support, but I cannot find relevant documents.
Sorry for so many questions 😂 Appreciate ur help very much👼
