"""Fetch Douyin profile fields into data/streamers.json.
|
||||
|
||||
Manual seed fields (id / platform / live_url / profile_url / heroes / tagline)
|
||||
are preserved. Profile enrichment (nickname, signature, counts, avatar) is
|
||||
best-effort via Douyin HTML RENDER_DATA + text fallback; failures keep the
|
||||
previous values.
|
||||
|
||||
Preview only — do not merge into relations/heroes or recommend.
|
||||
Part of refresh_web ``daily`` (soft-fail: never aborts the tier).
|
||||
|
||||
Usage:
|
||||
python fetch_streamers.py
|
||||
python fetch_streamers.py --ids xiaowang
|
||||
python fetch_streamers.py --out data/streamers.json
