採用 Bottle 實作簡易的 API-based login service。
開發環境：Ubuntu 12.04
$ apt-get install python-paste
$ python app.py

依據 client User-agent 與 IP，支援多個裝置使用不一樣的 token ，但同一裝置登入時可以沿用之前有效的 token
$ sqlite3 token.db ".schema"
CREATE TABLE Admin (
id TEXT PRIMARY KEY,
name TEXT UNIQUE NOT NULL,
password TEXT NOT NULL,
profile TEXT DEFAULT '{}'
);
$ sqlite3 token.db "SELECT * FROM Admin"
|admin|aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d|{"token": {"5d3cf7f3a070d914b23fa197b263caa5831b909e": {"pattern": "48a5df88e6b16f7a8f49d3146744f8dae41fadb7", "expired": "2013-11-15T23:46:17.374856"}, "2e52d3eb834e09f30509fcf4837478f207e71f59": {"pattern": "651294308142d18b74de84a732c000e49a0b7442", "expired": "2013-11-15T23:46:02.716752"}, "9fab7541a28253f2e70c2b43caae58e6740781fd": {"pattern": "d82b1d6b570d161d7d7e487b987d91843c11d713", "expired": "2013-11-15T23:55:32.803806"}}}
