在Cloud Foundry上使用SAPOfflineTokenServices时，JWT令牌验证出错

Question

我们使用SAP并将服务部署到S4HANA Cloud Platform，Cloud Foundry环境。

该服务绑定到Cloud Foundry UAA。使用@sap/approuter执行身份验证，然后在Authorization头中转发JWT令牌。

它在大多数情况下都工作得很好，但在随机周期之后，令牌验证似乎失败了：

在调用栈中可以看到，我们使用com.sap.xs2.security 0.22.2和com.sap.security.nw.sso.linuxx86_64.opt 1.0.0进行令牌验证。

你知道是什么导致了这个问题吗？

Answer 1

当底层JWT验证库试图加载公钥时，这似乎是一个问题。您可以尝试将com.sap.xs2.security:security-commons更新到最新的可用版本吗？SDK在其物料清单POM的版本2.3.1中引用版本0.28.6。
