So, in the documentation for third-party ASGI middlewares they will probably tell you to do something like:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

因此，有些第三方 ASGI 中间件的文档推荐以如下方式使用中间件：

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

但 FastAPI（实际上是 Starlette）提供了一种更简单的方式，能让内部中间件在处理服务器错误的同时，还能让自定义异常处理器正常运作。

为此，要使用 `app.add_middleware()` （与 CORS 中的示例一样）。

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

しかし FastAPI（正確には Starlette）は、内部ミドルウェアがサーバーエラーを処理し、カスタム例外ハンドラが正しく動作することを保証する、より簡単な方法を提供しています。

そのためには（CORS の例と同様に）`app.add_middleware()` を使います。

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

Então, na documentação de middlewares ASGI de terceiros, eles provavelmente dirão para você fazer algo como:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

Тож у документації до сторонніх middleware ASGI вам, імовірно, порадять зробити приблизно так:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

In der Dokumentation für ASGI-Middlewares von Drittanbietern wird Ihnen wahrscheinlich gesagt, dass Sie etwa Folgendes tun sollen:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

Dolayısıyla üçüncü taraf ASGI middleware'lerinin dokümantasyonunda muhtemelen şöyle bir şey yapmanızı söylerler:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

Entonces, en la documentación de middlewares ASGI de terceros probablemente te indicarán que hagas algo como:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

Ainsi, dans la documentation de middlewares ASGI tiers, on vous indiquera probablement de faire quelque chose comme :

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

하지만 FastAPI(정확히는 Starlette)는 더 간단한 방법을 제공하며, 이를 통해 내부 middleware가 서버 오류를 처리하고 커스텀 예외 핸들러가 올바르게 동작하도록 보장합니다.

이를 위해(그리고 CORS 예제에서처럼) `app.add_middleware()`를 사용합니다.

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()
