Douban Collection Export

Export Douban user collections (books, movies, music, games) to CSV files. Douban has no official data export; the official API shut down in 2018.

What This Skill Can Do

Full export of all book/movie/music/game collections via Frodo API
RSS incremental sync for daily updates (last ~10 items)
CSV output with UTF-8 BOM (Excel-compatible), cross-platform (macOS/Windows/Linux)
No login, no cookies, no browser required
Pre-flight user ID validation (fail fast on wrong ID)

What This Skill Cannot Do

Cannot export reviews (长评), notes (读书笔记), or broadcasts (广播)
Cannot filter by single category in one run (exports all 4 types together)
Cannot access private profiles (returns 0 items silently)

Why Frodo API (Do NOT Use Web Scraping)

Douban uses PoW (Proof of Work) challenges on web pages, blocking all HTTP scraping. We tested 7 approaches — only the Frodo API works. Do NOT attempt web scraping,

curl

with cookies, or Jina Reader.

See references/troubleshooting.md for the complete failure log of all 7 tested approaches and why each failed.

Security & Privacy

The API key and HMAC secret in the script are Douban's public mobile app credentials, extracted from the APK. They are shared by all Douban app users and do not identify you. No personal credentials are used or stored. Data is fetched only from

frodo.douban.com

.

Full Export (Primary Method)

bash

DOUBAN_USER=<user_id> python3 scripts/douban-frodo-export.py

Finding the user ID: Profile URL

douban.com/people/<ID>/

— the ID is after

/people/

. If the user provides a full URL, the script auto-extracts the ID.

Environment variables:

```
DOUBAN_USER
```
(required): Douban user ID (alphanumeric or numeric, or full profile URL)
```
DOUBAN_OUTPUT_DIR
```
(optional): Override output directory

Default output (auto-detected per platform):

macOS:
```
~/Downloads/douban-sync/<user_id>/
```

Windows:

%USERPROFILE%\Downloads\douban-sync\<user_id>\

Linux:
```
~/Downloads/douban-sync/<user_id>/
```

Dependencies: Python 3.6+ standard library only (works with

python3

or

uv run

).

Example console output:

Douban Export for user: your_douban_id
Output directory: /Users/you/Downloads/douban-sync/your_douban_id

=== 读过 (book) ===
  Total: 639
  Fetched 0-50 (50/639)
  Fetched 50-100 (100/639)
  ...
  Fetched 597-639 (639/639)
  Collected: 639

=== 在读 (book) ===
  Total: 75
  ...

--- Writing CSV files ---
  书.csv: 996 rows
  影视.csv: 238 rows
  音乐.csv: 0 rows
  游戏.csv: 0 rows

Done! 1234 total items exported to /Users/you/Downloads/douban-sync/your_douban_id

RSS Incremental Sync (Complementary)

bash

DOUBAN_USER=<user_id> node scripts/douban-rss-sync.mjs

RSS returns only the latest ~10 items (no pagination). Use Full Export first, then RSS for daily updates.

Output Format

Four CSV files per user:

Downloads/douban-sync/<user_id>/
├── 书.csv      (读过 + 在读 + 想读)
├── 影视.csv    (看过 + 在看 + 想看)
├── 音乐.csv    (听过 + 在听 + 想听)
└── 游戏.csv    (玩过 + 在玩 + 想玩)

Columns:

title, url, date, rating, status, comment

```
rating
```
: ★ to ★★★★★ (empty if unrated)
```
date
```
: YYYY-MM-DD (when the user marked it)
Safe to run multiple times (overwrites with fresh data)
Row counts may be slightly below Douban's displayed count due to delisted items

Workflow

Ask for Douban user ID (from profile URL, or accept full URL)

Run:

DOUBAN_USER=<id> python3 scripts/douban-frodo-export.py

Verify: row counts in console output should match, check with
```
wc -l <output_dir>/*.csv
```
(Optional) Set up RSS sync for daily incremental updates
