**FastAPI** 內建一套強大且直覺的 **<dfn title="也稱為：元件、資源、提供者、服務、可注入項">依賴注入</dfn>** 系統。

它被設計為易於使用，使任何開發者都能輕鬆將其他元件與 **FastAPI** 整合。

## 什麼是「依賴注入」 { #what-is-dependency-injection }

在程式設計中，「依賴注入」的意思是：你的程式碼（此處指你的「路徑操作函式 (path operation functions)」）可以宣告它為了正常運作所需要的各種東西：也就是「依賴」。

接著，這個系統（此處是 **FastAPI**）會負責做任何必要的事，將這些所需的依賴提供給你的程式碼（「注入」依賴）。

當你需要以下情境時，這特別有用：

* 共享邏輯（相同的邏輯一次又一次地使用）。
* 共用資料庫連線。
* 強制套用安全性、驗證、角色要求等。
* 以及許多其他事情...

同時把重複的程式碼降到最低。
