from fastapi import APIRouter, FastAPI

method_names = ["get", "put", "post", "delete", "options", "head", "patch", "trace"]

#### 操作

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。

#### Operação

"Operação" aqui se refere a um dos "métodos" HTTP.

Um dos:

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

...e os mais exóticos:

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

No protocolo HTTP, você pode se comunicar com cada rota usando um (ou mais) desses "métodos".

---

Ao construir APIs, você normalmente usa esses métodos HTTP para executar uma ação específica.

# OpenAPI Callbacks

You could create an API with a *path operation* that could trigger a request to an *external API* created by someone else (probably the same developer that would be *using* your API).

!!! tip
    Note that we're using async/await with the new `AsyncClient` - the request is asynchronous.

!!! warning
    If your application relies on lifespan events, the `AsyncClient` won't trigger these events. To ensure they are triggered, use `LifespanManager` from <a href="https://github.com/florimondmanca/asgi-lifespan#usage" class="external-link" target="_blank">florimondmanca/asgi-lifespan</a>.
