你也讀過如何處理 [使用 `CORSMiddleware` 的 CORS](../tutorial/cors.md)。

本節將示範如何使用其他中介軟體。

## 新增 ASGI 中介軟體 { #adding-asgi-middlewares }

由於 **FastAPI** 建立在 Starlette 上並實作了 <abbr title="Asynchronous Server Gateway Interface - 非同步伺服器閘道介面">ASGI</abbr> 規範，你可以使用任何 ASGI 中介軟體。

中介軟體不一定要為 FastAPI 或 Starlette 專門撰寫，只要遵循 ASGI 規範即可運作。

一般來說，ASGI 中介軟體是類別，預期第一個參數接收一個 ASGI 應用程式。

因此，在第三方 ASGI 中介軟體的文件中，通常會指示你這樣做：

```Python

Elbette bu optimal değil ve production için kullanmazsınız.

Production'da yukarıdaki seçeneklerden birini kullanırsınız.

Ama WebSockets'in server tarafına odaklanmak ve çalışan bir örnek görmek için en basit yol bu:

## Bir `websocket` Oluşturun { #create-a-websocket }

	//
	// TODO(aead): refactor this API call. It does not account
	// for multiple endpoints.
	Version(context.Context) (string, error)

	// APIs returns a list of APIs supported by the KMS server.
	//
	// TODO(aead): remove this API call. It's hardly useful.
	APIs(context.Context) ([]madmin.KMSAPI, error)

	// Stat returns the current KMS status.
	Status(context.Context) (map[string]madmin.ItemState, error)

	if target.closeErr {
		return errors.New("close error")
	}

	return nil
}

func (target ExampleTarget) IsActive() (bool, error) {
	return false, errors.New("not connected to target server/service")
}

// FlushQueueStore - No-Op. Added for interface compatibility
func (target ExampleTarget) FlushQueueStore() error {
	return nil
}

func TestTargetListAdd(t *testing.T) {

В этом случае клиент получит *HTTP 500 Internal Server Error*, как и должно быть, поскольку мы не вызываем `HTTPException` или что-то подобное, но на сервере **не будет никаких логов** или других указаний на то, какая была ошибка. 😱
