Docker容器跨原点错误

我正在用Microservices在本地构建一个应用程序,然后在docker容器上构建 我现在有Eureka,Zuul和springsecurity,一个使用springboot2的微服务,还有一个angular6客户端

,扩展 WebSecurityConfigurerAdapter 类,重写 configure 在本地它工作得很好。我的委托人( http://localhost:4200 http://localhost:8762/microservice/api/.. ,添加带有选项的基本身份验证标头。

但是对于Docker容器,用Docker Compose构建,情况就不一样了。Chrome抛出一个“未知异常”,而Firefox则指出了一个跨源错误 选项请求。客户端通过Zuul调用API,如下所示: http://gdt-gateway-proxy-service:8762/microservice/api/ ...

这是我生活的一部分 docker-compose.yml
