spring-boot - CAS 服务重定向到 http

Question

我想在使用 CAS 登录时重定向到一个 http 地址:

https://localhost:10000/cas/login?service=http%3A%2F%2Flocalhost%3A2401%2Fpath

我已经设置了

cas.server.prefix=http://localhost:10000/cas

到一个 http 地址，如 CAS login/redirect not working because of http/https conflict 中所述, 但在开始认证时出现以下错误:

2018-09-10 08:18:58.160 ERROR 25581 --- [io-10000-exec-3] o.a.c.c.C.[.[.[.[dispatcherServlet]      : Servlet.service() for servlet [dispatcherServlet] in context with path [/cas] threw exception [Request processing failed; nested exception is org.springframework.webflow.execution.ActionExecutionException: Exception thrown executing org.apereo.cas.web.flow.actions.RedirectToServiceAction@4f451c5a in state 'redirect' of flow 'login' -- action execution attributes were 'map[[empty]]'] with root cause

...

当切换到 https 重定向时一切正常。那么，这是根本不起作用还是我错过了配置？

顺便说一句:当我将 cas.server.prefix 更改为 https 时，错误更改为

Answer 1

好的伙计们，问题是 cas.server.prefix 定义末尾的空格字符
