Когда вы создаёте зависимость с `yield`, **FastAPI** внутренне создаёт для неё менеджер контекста и сочетает его с некоторыми другими связанными инструментами.

### Использование менеджеров контекста в зависимостях с `yield` { #using-context-managers-in-dependencies-with-yield }

/// warning | Внимание

Это, более или менее, «продвинутая» идея.

Если вы только начинаете работать с **FastAPI**, то лучше пока пропустить этот пункт.

这会在 `./src/client` 生成一个 TypeScript SDK。

你可以在其官网了解如何[安装 `@hey-api/openapi-ts`](https://heyapi.dev/openapi-ts/get-started)，以及阅读[生成结果](https://heyapi.dev/openapi-ts/output)的说明。

### 使用 SDK { #using-the-sdk }

现在你可以导入并使用客户端代码了。它可能是这样，并且你会发现方法有自动补全：

要发送的载荷也会有自动补全：

значение по умолчанию для `q` будет: `["foo", "bar"]`, и ответом будет:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

#### Просто `list` { #using-just-list }

Можно использовать `list` напрямую вместо `list[str]`:
