Description

When you download a TikTok user profile and use --write-info-json it write some info about the user in a json file.
Is it possible to add more data to it like follower count, following count, total likes, Bio and maybe also download the profile image?

Profile pic could be added as thumbnail. We don't currently have any standard fields for follower/following count. I think subscriber_count (follower count) makes sense to add, but not "following" count.

I dont understand what you mean by "bio"

Also, idk if these fields are easily extractable in the first place. @MinePlayersPE @Ashish0804 any idea

[Ashish0804]

the web api version (which i worked on) doesn't have these...the current implementation is using the mobile api which I have no idea about.

I meant the short text on someone's profile. I think it's called a bio.

Hey, I can add more profile data to my recent PR to fix user extraction.

[redraskal]

The short text is called a "signature" according to the api

Fixed in #4996 as well
