Mas isso ainda não é tão útil.

Vamos fazer com que ele nos forneça o usuário atual.

## Criar um modelo de usuário { #create-a-user-model }

Primeiro, vamos criar um modelo de usuário com Pydantic.

Da mesma forma que usamos o Pydantic para declarar corpos, podemos usá-lo em qualquer outro lugar:

can be tested. This section summarizes what one needs to take into consideration so that
tests won't fail when run in fips mode.

=== Muting tests in FIPS 140-2 mode

If the following limitations cannot be observed, or there is a need to actually test some use
case that is not available/allowed in fips mode, the test can be muted. For unit tests or Java
rest tests one can use

# 获取当前用户 { #get-current-user }

上一章中，（基于依赖注入系统的）安全系统向*路径操作函数*传递了 `str` 类型的 `token`：

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

但这并不实用。

接下来，我们学习如何返回当前用户。


## 创建用户模型 { #create-a-user-model }

首先，创建 Pydantic 用户模型。

与使用 Pydantic 声明请求体相同，并且可在任何位置使用：

{* ../../docs_src/security/tutorial002_an_py310.py hl[5,12:6] *}

## 创建 `get_current_user` 依赖项 { #create-a-get-current-user-dependency }

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

Pero eso aún no es tan útil. Vamos a hacer que nos dé el usuario actual.

## Crear un modelo de usuario { #create-a-user-model }

Primero, vamos a crear un modelo de usuario con Pydantic.

De la misma manera que usamos Pydantic para declarar cuerpos, podemos usarlo en cualquier otra parte:

* 對於 Cookie（cookies），在 `cookies` 參數中放一個 `dict`。

關於如何把資料傳給後端（使用 `httpx` 或 `TestClient`），更多資訊請參考 [HTTPX 文件](https://www.python-httpx.org)。

/// info

請注意，`TestClient` 接收的是可轉為 JSON 的資料，而不是 Pydantic models。

如果你的測試裡有一個 Pydantic model，並想在測試時把它的資料送給應用，你可以使用[JSON 相容編碼器](encoder.md)中介紹的 `jsonable_encoder`。

## 執行 { #run-it }

接下來，你只需要安裝 `pytest`。

請先建立並啟用一個[虛擬環境](../virtual-environments.md)，然後安裝，例如：
