本例中有 3 个查询参数：

* `needy`，必选的 `str` 类型参数
* `skip`，默认值为 `0` 的 `int` 类型参数
* `limit`，可选的 `int` 类型参数

/// tip | "提示"

还可以像在[路径参数](path-params.md#_8){.internal-link target=_blank} 中那样使用 `Enum`。

Viel mehr von all dem werden Sie in praktischer Anwendung im [Tutorial - Benutzerhandbuch](tutorial/index.md){.internal-link target=_blank} sehen.

/// tip | "Tipp"

是否使用冒号 `:` 等符号，或是不是 URL 并不重要。

这些细节只是特定的实现方式。

对 OAuth2 来说，它们都只是字符串而已。

## 全局纵览

首先，快速浏览一下以下代码与**用户指南**中 [OAuth2 实现密码哈希与 Bearer  JWT 令牌验证](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}一章中代码的区别。以下代码使用 OAuth2 作用域：

```Python hl_lines="2  4  8  12  46  64  105  107-115  121-124  128-134  139  153"
{!../../docs_src/security/tutorial005.py!}
```

下面，我们逐步说明修改的代码内容。
