我有两个：本地主机上的 STS 服务器和 Spring Web 应用程序。它奏效了。我已经测试了 OAuth2 授权代码授予流程 - 完全正常工作。

我将 STS 移至其他计算机，Web 应用程序在获取访问令牌时出现问题 - 完整跟踪（从 STS 重定向后停止/错误；就在从以下位置获取令牌的开始：https://sts-machine/authz/oauth2-resource/oauth/token端点；在访问 url 时停止https://localwebapp:7443/swd/webLogin?code=306b88903d394f0b8145b2e8035fd306&state=PtTrt8：）：
