【问题描述】：
我正在尝试开始使用 OAuth2 身份验证来保护我的 REST API。
我有一堆不安全的 API，并希望使用 Oauth2 保护它们。我正在逐字关注this tutorial。
当我发送访问令牌的 POST 请求时，我收到以下响应：
{
"error": "unauthorized",
"error_description": "Full authentication is required to access this resource"
}
这是我从 PostMan 发送的请求
POST /gigy/oauth/token HTTP/1.1
Host: localhost:8000
Content-Type: application/x-www-form-urlencoded
Authorization: Basic Z2lneTpzZWNyZXQ=
Cache-Control: no-cache
Postman-Token: 19ef4b4d-380b-2273-5d04-7ada3f7a7c85
grant_type=password&username=peter%40example.com&password=password
这里，Basic Z2lneTpzZWNyZXQ= 实际上是客户端 ID 和密码 (gigy:secret) 的 Base64 编码。
我确定我错过了什么，但不知道是什么。有人可以帮忙吗？
教程中没有评论部分或任何可以向作者寻求帮助的内容。
编辑 正如@dur 所指出的，我为 Spring Security 启用了 DEBUG 日志，日志如下：

虽然不确定这意味着什么，但我很确定我在某个地方犯了错误。请帮忙！
谢谢， 斯里拉姆·斯里达兰。
