angular - 通过docker容器调用rest API

问题描述

我已经使用spring boot和frontEnd使用angular 8开发了后端Rest API 我的问题是我已经通过docker-compose在同一台服务器中部署了后端和前端我需要一种方法来通过docker容器和网络进行角度调用rest API而不暴露我的后端休息API我试图用它的容器名称以角度调用后端，但它不起作用来自角度http://shop_soofybackendservice/api/departments的API链接示例

    deploy:
      mode: replicated

解决方案

服务之间通信的正确 URL（例如tomcatsoofyfrontend调用soofybackendservice）是 docker-compose 中服务的名称。在你的情况下它是soofybackendservice，因此端点是http://soofybackendservice:8080/api/departments

如果您的应用程序正在从远程浏览器/主机调用端点，那么您需要调用http://<<ip or the domain name of docker host>>:81/api/departments.
