我看到很多关于此的话题，但我找不到适合我的环境的解决方案。我在 z/OS UNIX shell 上运行一个 jar，我正在使用 HttpClient 的 Fluent API 发布到 REST 服务。该代码适用于 HTTP，但是，对于 SSL，它给了我一个证书错误。

如何在服务器上安装证书(我只有 URL，而服务器没有 openssl)。或者有什么办法可以完全绕过这个错误吗？我不太关心 SSL，因为 REST 网络服务也托管在同一台大型机上。
最佳答案
要获取服务器证书，您可以使用开放式 SSL 来这样做:
openssl s_client -showcerts -connect host.host:9999 </dev/null
服务器证书是第一个返回的证书，会被PEM格式。 CA证书是最终返回的证书，也是PEM格式。
然后您可以将它们的 PEM 导入 JKS 并配置 httpclient 以使用该 JKS。有关 PEM 到 JKS 的更多信息 http://www.agentbob.info/agentbob/79-AB.html
