### 依賴注入（Dependency Injection）

FastAPI 有一個使用簡單，但是非常強大的<abbr title='也叫做 "components", "resources", "services", "providers"'><strong>依賴注入</strong></abbr>系統。

* 依賴項甚至可以有自己的依賴，從而形成一個層級或**依賴圖**的結構。
* 所有**自動化處理**都由框架完成。
* 依賴項不僅能從請求中提取資料，還能**對 API 的路徑操作進行強化**，並自動生成文檔。
* 即使是依賴項中定義的*路徑操作參數*，也會**自動進行驗證**。

### Dependency Injection { #dependency-injection }

FastAPI enthält ein extrem einfach zu verwendendes, aber extrem mächtiges <abbr title='auch bekannt als „Komponenten“, „Resourcen“, „Dienste“, „Dienstanbieter“'><strong>Dependency Injection</strong></abbr> System.

* Selbst Abhängigkeiten können Abhängigkeiten haben, woraus eine Hierarchie oder ein **„Graph“ von Abhängigkeiten** entsteht.

You could need to tell the client that:

* The client doesn't have enough privileges for that operation.
* The client doesn't have access to that resource.
* The item the client was trying to access doesn't exist.
* etc.

In these cases, you would normally return an **HTTP status code** in the range of **400** (from 400 to 499).
