## Readiness probe

    这种命名方式是因为要使用与 OpenAPI 规范中相同的名字。以便在深入校验安全方案时，能通过复制粘贴查找更多相关信息。

`oauth2_scheme` 变量是 `OAuth2PasswordBearer` 的实例，也是**可调用项**。

以如下方式调用：

```Python
oauth2_scheme(some, parameters)
```

因此，`Depends` 可以调用 `oauth2_scheme` 变量。

### 使用

接下来，使用 `Depends` 把 `oauth2_scheme` 传入依赖项。

```Python hl_lines="10"
