Mais cela n’autorisera que certains types de communication, en excluant tout ce qui implique des informations d’identification : cookies, en-têtes Authorization comme ceux utilisés avec les Bearer Tokens, etc.

Ainsi, pour que tout fonctionne correctement, il est préférable d’indiquer explicitement les origines autorisées.

## 使用 `Response` 参数 { #use-a-response-parameter }

你可以在你的*路径操作函数*中声明一个`Response`类型的参数（就像你可以为cookies和头部做的那样）。

然后你可以在这个*临时*响应对象中设置`status_code`。

{* ../../docs_src/response_change_status_code/tutorial001_py310.py hl[1,9,12] *}

然后你可以像平常一样返回任何你需要的对象（例如一个`dict`或者一个数据库模型）。

如果你声明了一个`response_model`，它仍然会被用来过滤和转换你返回的对象。

**FastAPI**将使用这个*临时*响应来提取状态码（也包括cookies和头部），并将它们放入包含你返回的值的最终响应中，该响应由任何`response_model`过滤。

# `Response` class

You can declare a parameter in a *path operation function* or dependency to be of type `Response` and then you can set data for the response like headers or cookies.

You can also use it directly to create an instance of it and return it from your *path operations*.

Read more about it in the [FastAPI docs about returning a custom Response](https://fastapi.tiangolo.com/advanced/response-directly/#returning-a-custom-response)

This is "synchronous" work, you are "synchronized" with the cashier/cook 👨‍🍳. You have to wait 🕙 and be there at the exact moment that the cashier/cook 👨‍🍳 finishes the burgers and gives them to you, or otherwise, someone else might take them.

* JSON yerine *Form Data* göndermeniz gerekiyorsa, bunun yerine `data` parametresini kullanın.
* *headers* göndermek için, `headers` parametresine bir `dict` verin.
* *cookies* için, `cookies` parametresine bir `dict` verin.

Backend'e veri geçme hakkında daha fazla bilgi için (`httpx` veya `TestClient` kullanarak) [HTTPX dokümantasyonu](https://www.python-httpx.org)'na bakın.

/// info | Bilgi

* Якщо потрібно надіслати *Form Data* замість JSON, використовуйте параметр `data`.
* Щоб передати заголовки *headers*, використовуйте `dict` у параметрі `headers`.
* Для *cookies* використовуйте `dict` у параметрі `cookies`.

Докладніше про передачу даних у бекенд (за допомогою `httpx` або `TestClient`) можна знайти в [документації HTTPX](https://www.python-httpx.org).

## Curingas { #wildcards }

É possível declarar a lista como `"*"` (um "curinga") para dizer que tudo está permitido.

Mas isso só permitirá certos tipos de comunicação, excluindo tudo que envolva credenciais: cookies, cabeçalhos de autorização como aqueles usados ​​com Bearer Tokens, etc.

Então, para que tudo funcione corretamente, é melhor especificar explicitamente as origens permitidas.

## Usar `CORSMiddleware` { #use-corsmiddleware }

* If you need to send *Form Data* instead of JSON, use the `data` parameter instead.
* To pass *headers*, use a `dict` in the `headers` parameter.
* For *cookies*, a `dict` in the `cookies` parameter.

For more information about how to pass data to the backend (using `httpx` or the `TestClient`) check the [HTTPX documentation](https://www.python-httpx.org).
