それぞれのオプションの意味を見てみましょう：

* `main:app`： `main`は"`main`"という名前のPythonモジュール、つまりファイル`main.py`を意味します。そして `app` は **FastAPI** アプリケーションの変数名です。
    * main:app`はPythonの`import`文と同じようなものだと想像できます：

        ```Python
        from main import app
        ```

    * つまり、`main:app`のコロンは、`from main import app`のPythonの`import`の部分と同じになります。

* `--workers`： 使用するワーカー・プロセスの数で、それぞれがUvicornのワーカーを実行します。

You can also use it directly to create an instance of it and return it from your *path operations*.

You can import it directly from `fastapi`:

```python
from fastapi import Response
```

* déclarer le paramètre de chemin `item_id` en utilisant `Path`
* les avoir dans un ordre différent
* ne pas utiliser `Annotated`

...Python a une petite syntaxe spéciale pour cela.

Passez `*`, comme premier paramètre de la fonction.

中间件参数接收如下参数:

* `request`.
* 一个函数 `call_next` 它将接收 `request` 作为参数.
    * 这个函数将 `request` 传递给相应的 *路径操作*.
    * 然后它将返回由相应的*路径操作*生成的 `response`.
* 然后你可以在返回 `response` 前进一步修改它.

In general, ASGI middlewares are classes that expect to receive an ASGI app as the first argument.

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")
```
