这里的「操作」指的是一种 HTTP「方法」。

下列之一：

* `POST`
* `GET`
* `PUT`
* `DELETE`

...以及更少见的几种：

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

在 HTTP 协议中，你可以使用以上的其中一种（或多种）「方法」与每个路径进行通信。

---

在开发 API 时，你通常使用特定的 HTTP 方法去执行特定的行为。

通常使用：

* `POST`：创建数据。
* `GET`：读取数据。
* `PUT`：更新数据。
* `DELETE`：删除数据。

因此，在 OpenAPI 中，每一个 HTTP 方法都被称为「操作」。

我们也打算称呼它们为「操作」。
