Поскольку мы используем относительный URL, если ваш API расположен по адресу `https://example.com/`, то он будет ссылаться на `https://example.com/token`. А если ваш API расположен по адресу `https://example.com/api/v1/`, то он будет ссылаться на `https://example.com/api/v1/token`.

* `allow_origins` – Eine Liste von Origins, die Cross-Origin-Requests machen dürfen. z. B. `['https://example.org', 'https://www.example.org']`. Sie können `['*']` verwenden, um jedes Origin zuzulassen.
* `allow_origin_regex` – Ein Regex-String zum Abgleichen gegen Origins, die Cross-Origin-Requests machen dürfen. z. B. `'https://.*\.example\.org'`.

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo, e então instalar. Por exemplo:

```console
$ pip install python-multipart

就能以如下方式调用：

```Python
user_dict = user_in.dict()
```

现在，变量 `user_dict`中的就是包含数据的**字典**（变量 `user_dict` 是字典，不是 Pydantic 模型对象）。

以如下方式调用：

```Python
print(user_dict)
```

输出的就是 Python **字典**：

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': 'john.doe@example.com',
    'full_name': None,
}

Você pode estender o esquema do OpenAPI para uma *operação de rota* utilizando o parâmetro `openapi_extra`.

### Extensões do OpenAPI { #openapi-extensions }

Esse parâmetro `openapi_extra` pode ser útil, por exemplo, para declarar [Extensões do OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#specificationExtensions):

{* ../../docs_src/path_operation_advanced_configuration/tutorial005_py39.py hl[6] *}

    `APIRouter` class, used to group *path operations*, for example to structure
    an app in multiple files. It would then be included in the `FastAPI` app, or
    in another `APIRouter` (ultimately included in the app).

    Read more about it in the
    [FastAPI docs for Bigger Applications - Multiple Files](https://fastapi.tiangolo.com/tutorial/bigger-applications/).

    ## Example

    ```python

  /**
   * Returns the {@link InetAddress} having the given string representation.
   *
   * <p>This deliberately avoids all nameservice lookups (e.g. no DNS).
   *
   * <p>This method accepts non-ASCII digits, for example {@code "１９２.１６８.０.１"} (those are fullwidth
   * characters). That is consistent with {@link InetAddress}, but not with various RFCs. If you
   * want to accept ASCII digits only, you can use something like {@code
