如何更改通过Keycloak令牌交换创建的访问令牌的内容

Question

我的目标是获得两个资源服务器特定的访问令牌，其中只包含各自资源服务器特定的数据。

我有以下设置：一个公共客户端使用2个资源服务器。

在配置客户机、用户、领域角色、客户机作用域并使用scope参数之后，我能够创建2个不同的资源服务器特定的访问令牌：

      "uma_authorization"
    ]
  },
  "scope": "email profile",
  "email_verified": false,
  "preferred_username": "bill"
}

我的问题是，如何将Keycloak配置为第二个访问令牌不包含角色“offline_access”和“uma_authorization”以及AUD：“other_resource_server”、“fitness-client”、“other_client”和“account”？

Answer 1

我找到了解决办法：-）

我必须将资源服务器2的设置-访问类型配置从只承载改为机密，禁用所有流/授权，通过这一更改，我也可以在资源服务器2中配置客户端范围和范围。

即使我不需要机密（流/授权、凭据等），我也必须从只承载更改为机密，这不是很好，但这使得更改访问令牌输出成为可能。
