angular - ng build --prod 允许缺少原点(404 禁止)

Question

我在我的应用程序之外调用 REST APIS 并且我总是得到

Allow-Origin' header is present on the requested resource (403 Forbidden).

我将我的 tomcat 服务器配置为允许来源。

与

ng serve --proxy-config proxy.conf.json

它工作正常但是之后

ng build --prod

我遇到了这个问题。那么为什么它使用 ng serve 而不是 ng build？这在我的服务器端不是问题，否则它不能与 ng 服务器或 http 请求等一起工作。我可以在这里做什么？
