OpenAPI 中定义的安全模式，包括：

* HTTP 基本认证。
* **OAuth2**（也使用 **JWT tokens**）。在 [使用 JWT 的 OAuth2](tutorial/security/oauth2-jwt.md) 查看教程。
* API 密钥，在:
    * 请求头。
    * 查询参数。
    * Cookies，等等。

加上来自 Starlette（包括 **session cookie**）的所有安全特性。

所有的这些都是可复用的工具和组件，可以轻松与你的系统，数据仓库，关系型以及 NoSQL 数据库等等集成。

### 依赖注入 { #dependency-injection }

都可以作為 **FastAPI** 的相依。

事實上，FastAPI 內部就是使用這兩個裝飾器。

///

## 使用 `yield` 的資料庫相依 { #a-database-dependency-with-yield }

例如，你可以用它建立一個資料庫 session，並在完成後關閉。

只有 `yield` 之前（含 `yield` 本身）的程式碼會在產生回應之前執行：

{* ../../docs_src/dependencies/tutorial007_py310.py hl[2:4] *}

由 `yield` 產生的值會被注入到路徑操作（path operation）與其他相依中：

	}
	type Item struct {
		gorm.Model
		Logo     string        `gorm:"not null;type:varchar(50)"`
		Contents []ItemContent `gorm:"foreignKey:ItemID"`
	}

	tx := DB.Session(&gorm.Session{})
	tx.Migrator().DropTable(&ItemContent{}, &Item{})
	tx.AutoMigrate(&ItemContent{}, &Item{})

	item := Item{
		Logo: "logo",
		Contents: []ItemContent{
			{Name: "name", LanguageCode: "en"},
