Webpack在生产构建中无法找到公共文件夹。

Question

我的当前文件夹结构

- app
- build
- public
  - simulation
    - index.html
- server

我在 public > simulation 文件夹中有一个 .html 文件。

我正在一个 React 组件内的 iFrame 中打开这个 HTML 文件。

export default function B2BSalesSimulation(props) {
    return (<>
        <iframe title='mytitle' src={`${props.baseURl}/simulation/index.html`} width='100%' height='800px'>
            Your browser does not support simulation
        </iframe>
    </>)
}

当我本地运行代码时，我能够在iFRAME内查看索引文件。没有提供特殊路由。

但是当我将其部署到服务器上[构建在nginx服务器上运行]。它在iFRAME内显示未找到页面。

无论哪种情况下，iframe的URL都是相同的，只有主机不同。

你能检查构建资产吗？它们是否包含你的公共文件夹？如果没有，这可能会有所帮助：https://dev59.com/cFcO5IYBdhLWcg3wkij2 - David

看来我只需要使用 Copy-Webpack-Plugin。

首先安装了这个包。

npm i copy-webpack-plugin

要将所有位于'app/public/simulation'的资源复制到'dist/simulation'中，我只需要在我的webpack配置文件中添加以下内容：

  plugins: [
    new CopyWebpackPlugin([
      { from: 'app/public/simulation', to: 'simulation' }
    ])
  ]
