Quark Anonymous Download

Quark Anonymous Download

Use scripts/quark_anonymous_download.py. It uses only Python 3 standard library modules, an in-memory anonymous cookie jar, and Quark's public-share endpoints. Never add account cookies, browser profiles, saved credentials, or login steps.

Workflow

1. List before downloading unless the requested file name is exact and unambiguous:

   python3 scripts/quark_anonymous_download.py list 'https://pan.quark.cn/s/SHARE_ID'
   

2. Download one exact file, a uniquely matching name fragment, or all files:

   python3 scripts/quark_anonymous_download.py download URL --name 'exact-file.zip' --output-dir OUTPUT
   python3 scripts/quark_anonymous_download.py download URL --contains '关键词' --output-dir OUTPUT
   python3 scripts/quark_anonymous_download.py download URL --all --output-dir OUTPUT
   

   If --contains matches several files, stop and use the listed path with --name, or pass --latest only when the user explicitly wants the newest updated_at version.

3. Add --incremental when the user wants version history. It appends the remote updated_at timestamp in Beijing time, preserves older files, and skips an existing matching dated file.

4. Report each completed file with its remote path, byte size, and SHA-256. Do not extract, execute, install, or inspect executable payloads unless the user separately asks.

Limits and failures

• Reissue a fresh temporary direct URL when a request fails with HTTP 412, then use a Range request with Referer: https://pan.quark.cn/.
• Treat API errors such as download file size limit, require login, or a missing direct URL as a server-side anonymous-download restriction. Report the affected files; do not claim success and do not attempt a login bypass.
• The script validates response ranges, final byte size, SHA-256, and writes with a temporary file followed by atomic replacement.
• Share IDs, file IDs, tokens, direct URLs, timestamps, availability, and hashes are remote and time-specific. Obtain them anew for every share.
