Pixiv OAuth Token Fetcher

🌍 English | 简体中文

A Python automation tool that simulates Pixiv OAuth login, captures the authorization code, and exchanges it for an access token.

📦 Features

• ✅ Automated Pixiv login (username/password)
• ✅ Headless mode support
• ✅ Visible (non-headless) mode support
• ✅ Console-based authorization code capture via CDP
• ✅ Access token & refresh token retrieval
• ✅ Slow typing to bypass bot detection
• ✅ Auto-skip security prompt pages (Passkeys / 2FA reminders)
• ✅ Multi-selector fallback for Pixiv login form compatibility
• ✅ Token cache + auto refresh (browser login only on first run / when refresh token expires)
• ✅ Multi-account support (one cache file per email under ~/.pixiv-token/)
• ✅ Machine-readable output (--json, --print <field>) — result on stdout, logs on stderr
• ✅ Standard logging integration — library is silent by default; consumers configure their own handlers
• ✅ Installable as a library (pip install .) and CLI (pixiv-token)

🚀 Installation

1. Clone the repository

git clone https://github.com/piglig/pixiv-token.git
cd pixiv-token

2. Install dependencies

Recommended Python version: >=3.8

# As a dev checkout
pip install -r requirements.txt

# Or install as a package (exposes the `pixiv-token` CLI)
pip install .

⚙️ Usage

Command line

# First run for an account — credentials required, browser login performed and token cached
python pixiv_token_fetcher.py -u "your_email" -p "your_password"

# Subsequent runs — cache is used; if expired, refresh_token is used automatically
# (auto-selected when only one account is cached)
python pixiv_token_fetcher.py

# Multiple accounts — select which cached account to use
python pixiv_token_fetcher.py --account "your_email"

# List all cached accounts and their expiry
python pixiv_token_fetcher.py --list-accounts

# Visible browser mode (when login is needed)
python pixiv_token_fetcher.py -u "your_email" -p "your_password" --no-headless

# Force a fresh browser login (ignore cache)
python pixiv_token_fetcher.py -u "your_email" -p "your_password" --force-login

# Custom cache directory
python pixiv_token_fetcher.py --cache-dir ./tokens

# Machine-readable: full record as JSON on stdout (status logs go to stderr)
python pixiv_token_fetcher.py --json

# Pipeline-friendly: print a single field only (no labels, no emoji)
ACCESS_TOKEN=$(python pixiv_token_fetcher.py --print access_token)
REFRESH=$(python pixiv_token_fetcher.py --print refresh_token)

# Verbosity (logs are written to stderr only)
python pixiv_token_fetcher.py --verbose   # debug-level logs
python pixiv_token_fetcher.py --quiet     # warnings/errors only

# If installed via `pip install .`, the same CLI is available as `pixiv-token`
pixiv-token --print access_token

Default cache directory: ~/.pixiv-token/, one file per account (<email>.json). Each file stores username, access_token, refresh_token, and expires_at — treat the directory like a credential store.

As a module

from pixiv_token_fetcher import PixivTokenFetcher

# First login for an account — credentials required
fetcher = PixivTokenFetcher(
    username="your_pixiv_email",
    password="your_pixiv_password",
    headless=True,
)
token = fetcher.get_token()  # cache → refresh → browser login (in that order)
print(token["access_token"])

# Later, reuse the cache without credentials
fetcher = PixivTokenFetcher(account="your_pixiv_email")
token = fetcher.get_token()

# List cached accounts
for acc in PixivTokenFetcher().list_cached_accounts():
    print(acc["username"], acc["expires_at"])

The returned token dict always contains username, access_token, refresh_token, and expires_at (unix seconds).

Logging: the library uses the standard logging module under the logger name pixiv_token_fetcher and ships no handlers by default (silent on import). Wire it into your own setup:

import logging
logging.getLogger("pixiv_token_fetcher").setLevel(logging.INFO)
logging.basicConfig(format="%(asctime)s %(levelname)s %(message)s")

🔧 How It Works

1. Cache Lookup — Resolves the account (explicit --account/--username, or auto-detected if only one is cached) and reads ~/.pixiv-token/<email>.json; if access_token is still valid, returns it immediately
2. Refresh — If the access token has expired, calls Pixiv's grant_type=refresh_token endpoint and updates the cache (no browser involved)
3. PKCE Generation (fallback) — Generates code_verifier and code_challenge for OAuth PKCE flow
4. Browser Launch — Launches a stealth Chromium build to perform the login
5. Auto Login — Fills in email/password with slow typing to mimic human input
6. Code Capture — Intercepts the pixiv://account/login?code=... redirect via CDP (Network.requestWillBeSent)
7. Security Prompt Handling — Automatically clicks "Remind me later" / "Skip" if Pixiv shows a Passkeys/2FA setup page
8. Token Exchange — Exchanges the authorization code for access & refresh tokens and writes them to the cache

📌 Notes

• ⚠️ Do not hardcode credentials in production environments. Use environment variables or a secrets manager.
• ❌ This is not an official Pixiv SDK. Changes to Pixiv's login page may affect functionality.
• 🛡 Please comply with Pixiv's Terms of Service.
• 🔁 The refresh token is long-lived. You typically only need to run this tool once.

🧪 Example Output

[INFO] opening pixiv login page
[INFO] filled username field
[INFO] filled password field
[INFO] submitted login form
[INFO] skipping security prompt via 'Remind me later' button
[INFO] captured authorization code
access_token:  xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
refresh_token: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
expires_at:    2026-05-25 14:32:10

The [INFO] lines are logs (written to stderr); access_token / refresh_token / expires_at are the result (written to stdout). Pipe-friendly.

🧪 Testing

Unit tests cover the non-browser logic (cache I/O, account resolution, token-refresh orchestration, CLI output contracts). Browser flow is mocked, so the suite runs in under a second without needing CloakBrowser/Playwright installed.

pip install -e ".[test]"
