這大致算是一個「進階」概念。

如果你剛開始學習 **FastAPI**，此處可以先跳過。

在 Python 中，你可以透過[建立一個擁有 `__enter__()` 與 `__exit__()` 兩個方法的類別](https://docs.python.org/3/reference/datamodel.html#context-managers)來建立情境管理器。

你也可以在 **FastAPI** 的含 `yield` 相依中，於相依函式內使用 `with` 或 `async with` 陳述式來使用它們：

	for i := range totalParts {
		// hard coding hash and algo value for the checksum, Since we are benchmarking the parsing of xl.meta the magnitude doesn't affect the test,
		// The magnitude doesn't make a difference, only the size does.

/// warning | 警告

务必**始终**使用 `CMD` 指令的**exec 形式**，如下所述。

///

#### 使用 `CMD` - Exec 形式 { #use-cmd-exec-form }

[`CMD`](https://docs.docker.com/reference/dockerfile/#cmd) 指令有两种写法：

✅ **Exec** 形式：

```Dockerfile
# ✅ 推荐
CMD ["fastapi", "run", "app/main.py", "--port", "80"]
```

⛔️ **Shell** 形式：

```Dockerfile
# ⛔️ 不要这样

   *
   * <p>To avoid having this type, we could use {@code FlatMapSpliterator} directly. The main
   * advantages to having the type are the ability to use its constructor reference below and the
   * parallelism with the primitive version. In short, it makes its caller ({@code flatMap})
   * simpler.
   *
   * @param <InElementT> the element type of the input spliterator

Asegúrate de **siempre** usar la **forma exec** de la instrucción `CMD`, como se explica a continuación.

///

#### Usar `CMD` - Forma Exec { #use-cmd-exec-form }

La instrucción Docker [`CMD`](https://docs.docker.com/reference/dockerfile/#cmd) se puede escribir usando dos formas:

✅ **Forma Exec**:

```Dockerfile
# ✅ Haz esto
CMD ["fastapi", "run", "app/main.py", "--port", "80"]
```

⛔️ **Forma Shell**:

Stellen Sie sicher, dass Sie **immer** die **exec form** der Anweisung `CMD` verwenden, wie unten erläutert.

///

#### `CMD` – Exec Form verwenden { #use-cmd-exec-form }

Die [`CMD`](https://docs.docker.com/reference/dockerfile/#cmd) Docker-Anweisung kann in zwei Formen geschrieben werden:

✅ **Exec** form:

```Dockerfile
# ✅ Tun Sie das
CMD ["fastapi", "run", "app/main.py", "--port", "80"]
```
