在使用 oauth 2.0 资源服务器 jwt 时，有时会遇到权限（授权）问题。这是许多开发人员在开发过程中经常遇到的一个挑战。oauth 2.0 是一种用于授权的开放标准，它允许用户授权第三方应用访问其受保护的资源。jwt（json web token）是一种用于在网络应用之间传递声明的方式。然而，在实践中，可能会出现一些权限问题，比如授权失败、无法获取访问令牌等。本文将针对这些问题进行解析，并提供一些解决方案，帮助开发人员更好地使用 oauth 2.0 资源服务器 jwt。

问题内容

我正在尝试使用 oauth 2.0 资源服务器 jwt 在一个简单的应用程序中使用 jwt 配置访问授权。

整个身份验证部分工作正常，但我在授权方面遇到问题。即使令牌中存在正确的权限，所有受保护的端点也会给出 403 forbidden 错误。

我尝试使用默认范围（scope_）属性并将配置更改为角色（role_），但问题仍然存在。

有谁知道怎么解决吗？
