1） 当我在没有minikube的情况下运行应用程序时，应用程序运行良好。
2） 当我用minikube运行应用程序并点击时 前端很好。
3） 只要我尝试点击登录按钮，应用程序尝试连接到 后端，我得到上述错误。
4） 由于某些原因，在上运行时无法连接到后端 minikube和我一直在获取未找到的资源错误

192.168.99.111是minikube ip

我是kubernetes的新手，非常感谢您在调试过程中提供的任何帮助

更新

我认为入口控制器有问题 当我在入口控制器日志中看到它时

192.168.99.1-[192.168.99.1]-[10/Jun/2019:00:07:58+0000]“POST/api/auth/login HTTP/1.1”40419http://192.168.99.116/auth/login?redirect=/“”Mozilla/5.0（Macintosh；英特尔Mac OS X 10_14_5）AppleWebKit/537.36（KHTML，类似Gecko）Chrome/74.0.3729.131 Safari/537.36“520 0.001[默认值-server-cluster-ip-service-8080]172.17.0.8:8080 19 0.002 404 702298110b92307929f9817bb50c47ff

相反，它应该是

为什么
/api
会被删除？

这就是
nginx.ingres.kubernetes.io/rewrite-target://
为您所做的。它会删除入口配置中的前缀。您可以删除此注释以在路径中保留
/api/

请参阅：

入口配置没有问题。
您的后端应用程序具有将自身重定向到
/auth/login
路径的规则，如果要添加前缀，则无法通过入口控制器解决此问题。您必须配置后端API，以通过应用程序代码处理这些URL。

我发现了问题。我不想重写
