Hug 啟發了 APIStar 的部分設計，也是我覺得最有前景的工具之一，與 APIStar 並列。

Hug 啟發 **FastAPI** 使用 Python 型別提示宣告參數，並自動產生定義 API 的結構。

Hug 啟發 **FastAPI** 在函式中宣告 `response` 參數以設定標頭與 Cookie。

### [APIStar](https://github.com/encode/apistar) (<= 0.5) { #apistar-0-5 }

在決定打造 **FastAPI** 之前，我找到了 **APIStar** 伺服器。它幾乎具備我所尋找的一切，而且設計很出色。

它是我見過最早使用 Python 型別提示來宣告參數與請求的框架實作之一（早於 NestJS 與 Molten）。我與 Hug 幾乎在同時間發現它。不過 APIStar 使用的是 OpenAPI 標準。

Bunu yönetmek için önce `username` ve `password` değerlerini UTF-8 ile encode ederek `bytes`’a dönüştürürüz.

Sonra `secrets.compare_digest()` kullanarak `credentials.username`’in `"stanleyjobson"` ve `credentials.password`’ün `"swordfish"` olduğundan emin olabiliriz.
