No tutorial principal você leu como adicionar [Middleware Personalizado](../tutorial/middleware.md){.internal-link target=_blank} à sua aplicação.

E então você também leu como lidar com [CORS com o `CORSMiddleware`](../tutorial/cors.md){.internal-link target=_blank}.

Nesta seção, veremos como usar outros middlewares.

## Adicionando middlewares ASGI { #adding-asgi-middlewares }

# 高级中间件

用户指南介绍了如何为应用添加[自定义中间件](../tutorial/middleware.md){.internal-link target=_blank} 。

以及如何[使用 `CORSMiddleware` 处理 CORS](../tutorial/cors.md){.internal-link target=_blank}。

本章学习如何使用其它中间件。

## 添加 ASGI 中间件

因为 **FastAPI** 基于 Starlette，且执行 <abbr title="Asynchronous Server Gateway Interface，异步服务器网关界面">ASGI</abbr> 规范，所以可以使用任意 ASGI 中间件。

中间件不必是专为 FastAPI 或 Starlette 定制的，只要遵循 ASGI 规范即可。

总之，ASGI 中间件是类，并把 ASGI 应用作为第一个参数。

Ви можете під'єднати дебагер у Вашому редакторі коду, наприклад, у Visual Studio Code або PyCharm.

## Виклик `uvicorn`

У Вашому FastAPI-додатку імпортуйте та запустіть `uvicorn` безпосередньо:

### Про `__name__ == "__main__"`

Головна мета використання `__name__ == "__main__"` — це забезпечення виконання певного коду тільки тоді, коли файл запускається безпосередньо:

		h.ServeHTTP(w, r)

		switch {
		case test.ShouldFail && w.Code == http.StatusOK:
			t.Errorf("Test %d: should fail but status code is HTTP %d", i, w.Code)
		case !test.ShouldFail && w.Code != http.StatusOK:
			t.Errorf("Test %d: should not fail but status code is HTTP %d and not 200 OK", i, w.Code)
		}
	}
