Neste caso, o **FastAPI** nunca tocará ou se importará com o `__init__`, nós vamos utilizar diretamente em nosso código.

## Crie uma instância { #create-an-instance }

Nós poderíamos criar uma instância desta classe com:

你希望前端能用使用者名稱與密碼向後端進行身分驗證。

我們可以用 OAuth2 搭配 FastAPI 來實作。

但不必通讀整份冗長規格只為了找出你需要的幾個重點。

就用 FastAPI 提供的工具處理安全性。

## 看起來如何 { #how-it-looks }

先直接跑範例看效果，再回頭理解其原理。

## 建立 `main.py` { #create-main-py }

將範例複製到檔案 `main.py`：

{* ../../docs_src/security/tutorial001_an_py310.py *}

## 執行 { #run-it }

/// info

我们可以用 **OAuth2** 在 **FastAPI** 中实现它。

但为了节省你的时间，不必为获取少量信息而通读冗长的规范。

我们直接使用 **FastAPI** 提供的安全工具。

## 效果预览 { #how-it-looks }

先直接运行代码看看效果，之后再回过头理解其背后的原理。

## 创建 `main.py` { #create-main-py }

把下面的示例代码复制到 `main.py`：

{* ../../docs_src/security/tutorial001_an_py310.py *}

## 运行 { #run-it }
