node.js - Angular 无法使用直接 url 打开页面，在 Node.js Express 服务器上运行

问题描述

我有一个 Angular 9 应用程序，它在 Node.js 服务器上运行。从 IntelliJ 在本地运行时，路由工作正常。我可以通过更改 url 直接转到任何页面，例如：

mywebsite.com/page

但是，如果我部署应用程序，路由会刹车。如果我打开网站

mywebsite.com

如果我使用网站上的菜单，我可以访问所有页面，但如果我直接访问任何 url，例如

mywebsite.com/page

我明白了

Cannot GET /page

为什么加载不出来？

更新：

    const server = app.listen(8080, () => {

该应用程序在 Docker 容器中运行

Dockerfile

FROM node:lts-alpine

WORKDIR /app

COPY node_modules node_modules/
COPY app.js ./
COPY dist/ public/

EXPOSE 8080
CMD ["node", "app.js"]
