OpenAPI визначає, що кожна «операція шляху» потребує опису відповіді.

Тому, якщо ви його не надасте, FastAPI автоматично згенерує «Successful response».

## 檢查 { #check-it }

開啟互動式文件：[http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)。

你會看到類似這樣：

<img src="/img/tutorial/security/image01.png">

/// check | Authorize 按鈕！

你會看到一個新的「Authorize」按鈕。

而你的「路徑操作」右上角也會出現一個小鎖頭可以點擊。

///

點擊後會跳出一個小視窗，讓你輸入 `username` 與 `password`（以及其他可選欄位）：

## 查看 { #check-it }

打开交互式文档：[http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)。

你会看到类似这样的界面：

<img src="/img/tutorial/security/image01.png">

/// check | Authorize 按钮！

页面右上角已经有一个崭新的“Authorize”按钮。

你的*路径操作*右上角还有一个可点击的小锁图标。
