The Douyin creator center UI (https://creator.douyin.com/creator-micro/) has been refactored and breaks the existing login flow in three independent ways. This commit fixes all of them.
1. QR code selector no longer matches
The previous selector chain assumed the QR sat in a sibling div with an aria-label of 二维码. After the refactor, the QR is rendered as a base64 PNG inside div#animate_qrcode_container and has no aria-label. The new chain is a 4-tier fallback (id -> class partial -> container partial -> aria-label) preceded by a networkidle wait so the SPA is fully hydrated before we look.
2. cookie_auth() race condition
page.goto + wait_for_url(5000) + immediate get_by_text count() was racy: the SPA had not finished hydrating, so count() could return 0 even when the page actually shows the login card, leading to false-positive 'cookie valid' results. Replaced with a 10s polling loop that returns invalid if neither the login-card text nor the upload-page text is observed.
3. _wait_for_douyin_login() only waited for sessionid cookie (120s)
During 2FA the cookie is not yet set; the page is still on the verification screen and the URL has already changed. The new loop detects 2FA input fields, logs a warning so the user knows to type the SMS code, and keeps polling. Timeout raised to 200s to accommodate the slower human-in-the-loop flow.
Verified the selector chain against the live creator.douyin.com page: returns a 2.9 KB base64 PNG that decodes into a valid douyin scan_login URL.
- Wait until the upload progress reaches 100% before clicking publish. The
browser-based upload only progresses while the page is open, so publishing
(and closing the browser) mid-upload cut it off and left the video stuck
partway (e.g. 76%).
- Add optional YT_PROXY (conf.py): where youtube.com is blocked, direct
connections time out and the chromium does not use the system proxy, so
allow pointing it at a local proxy explicitly.
Add a YouTube uploader that follows the existing cookie-based browser
automation pattern (uploader/youtube_uploader + sau youtube CLI:
login/check/upload-video). Supports title/description/tags, thumbnail,
adding to a playlist (for series), and visibility (public/unlisted/private).
Browser automation is used instead of the official Data API on purpose:
videos uploaded by an unaudited API project are force-locked to private
and cannot be made public without Google's compliance audit, which is
impractical for personal/single-channel use. Browser automation has no
such restriction and matches how every other platform here works.
- Add tag count validation (max 10) in both CLI and uploader layers
- CLI: exit with error if tags > 10, prompt user to reduce
- Uploader: truncate to first 10 with warning as fallback
- Prevents infinite loop when XHS UI rejects excess tags
- Add check_original_declaration() to auto-check original content
declaration before publishing (video and note modes)
- Gracefully skips if the option is not present on the page
Move newline normalization out of the f-string expression so the CLI can import and run under Python 3.11+ without syntax errors.
