而且你可以為安全需求使用任意模型或資料（本例中是 Pydantic 模型 `User`）。

但你不受限於某個特定的資料模型、類別或型別。

想在模型中只有 `id` 與 `email` 而沒有任何 `username`？當然可以。你可以用同樣的工具達成。

想只用一個 `str`？或只用一個 `dict`？或直接使用資料庫類別的模型實例？都可以，一樣運作。

你的應用其實沒有真人使用者登入，而是機器人、bot，或其他系統，只持有 access token？同樣沒有問題。

只要用任何你的應用需要的模型、類別或資料庫即可。**FastAPI** 的依賴注入系統都支援。

## 程式碼大小 { #code-size }

這個範例看起來可能有點冗長。記住我們把安全、資料模型、工具函式與*路徑操作*混在同一個檔案中。

但重點在這裡。

安全與依賴注入相關的內容只需要寫一次。
