### 3. Example

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

### `response` の前後

*path operation* が `request` を受け取る前に、 `request` とともに実行されるコードを追加できます。

また `response` が生成された後、それを返す前にも追加できます。

例えば、リクエストの処理とレスポンスの生成にかかった秒数を含むカスタムヘッダー `X-Process-Time` を追加できます:

```Python hl_lines="10  12-13"
{!../../docs_src/middleware/tutorial001.py!}
```

如果您的远程服务器或虚拟机只有 3 GB RAM，尝试加载超过 4 GB RAM 将导致问题。 🚨


### 多进程 - 一个例子

在此示例中，有一个 **Manager Process** 启动并控制两个 **Worker Processes**。

该管理器进程可能是监听 IP 中的 **端口** 的进程。 它将所有通信传输到工作进程。

这些工作进程将是运行您的应用程序的进程，它们将执行主要计算以接收 **请求** 并返回 **响应**，并且它们将加载您放入 RAM 中的变量中的任何内容。

当然，除了您的应用程序之外，同一台机器可能还运行**其他进程**。
