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。
