由于文件 `app/routers/users.py` 和 `app/routers/items.py` 是同一 Python 包 `app` 一个部分的子模块，因此我们可以使用单个点 ` .` 通过「相对导入」来导入它们。

### 导入是如何工作的 { #how-the-importing-works }

这段代码：

```Python
from .routers import items, users
```

表示：

* 从该模块（`app/main.py` 文件）所在的同一个包（`app/` 目录）开始...
* 寻找 `routers` 子包（位于 `app/routers/` 的目录）...

Its possible that some downloads will fail and it'll be impossible to restart
them. This is a bug in vagrant. See the instructions here for how to work
around it:
https://github.com/mitchellh/vagrant/issues/4479

Some vagrant commands will work on all VMs at once:

------------------
vagrant halt
vagrant destroy -f

XML içeriğinizi bir string içine koyabilir, onu bir `Response` içine yerleştirip döndürebilirsiniz:

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}

## Bir Response Model Nasıl Çalışır { #how-a-response-model-works }

Bir path operation içinde [Response Model - Dönüş Tipi](../tutorial/response-model.md) deklare ettiğinizde, **FastAPI** veriyi Pydantic kullanarak JSON'a serialize etmek için bunu kullanır.

Вы можете поместить ваш XML-контент в строку, поместить её в `Response` и вернуть:

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}

## Как работает модель ответа { #how-a-response-model-works }

Когда вы объявляете [Модель ответа - возвращаемый тип](../tutorial/response-model.md) в операции пути, **FastAPI** будет использовать её для сериализации данных в JSON с помощью Pydantic.

Sie könnten Ihren XML-Inhalt als String in eine `Response` einfügen und sie zurückgeben:

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}

## Funktionsweise eines Responsemodells { #how-a-response-model-works }

Wenn Sie in einer Pfadoperation ein [Responsemodell - Rückgabetyp](../tutorial/response-model.md) deklarieren, wird **FastAPI** es verwenden, um die Daten mithilfe von Pydantic nach JSON zu serialisieren.

Podrías poner tu contenido XML en un string, poner eso en un `Response`, y devolverlo:

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}

## Cómo funciona un Response Model { #how-a-response-model-works }

Cuando declaras un [Response Model - Return Type](../tutorial/response-model.md) en una *path operation*, **FastAPI** lo usará para serializar los datos a JSON, usando Pydantic.

Você pode colocar o seu conteúdo XML em uma string, colocar em uma `Response`, e retorná-lo:

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}

## Como funciona um Modelo de resposta { #how-a-response-model-works }

Quando você declara um [Modelo de resposta - Tipo de retorno](../tutorial/response-model.md) em uma operação de rota, o **FastAPI** irá usá-lo para serializar os dados para JSON, usando o Pydantic.

	// we wrap the underlying error, make sure when you
	// are modifying this code that you do so, if and when
	// you want to add extra context to your error. This
	// ensures top level retry works accordingly.

	// Initialize config system.
	if err := globalConfigSys.Init(newObject); err != nil {
		if configRetriableErrors(err) {
			return fmt.Errorf("Unable to initialize config system: %w", err)
		}

 * underlying map and {@link #createCollection()} method return threadsafe classes. Concurrent read
 * operations will work correctly. To allow concurrent update operations, wrap your multimap with a
 * call to {@link Multimaps#synchronizedMultimap}.
 *
 * <p>For serialization to work, the subclass must specify explicit {@code readObject} and {@code
 * writeObject} methods.

 *  Fix: Change how `H2_PRIOR_KNOWLEDGE` works with HTTP proxies. Previously OkHttp assumed the
    proxy itself was a prior knowledge HTTP/2 server. With this update, OkHttp attempts a `CONNECT`
