ruby-on-rails - MP4 文件未在 React / Rails 应用程序上加载

问题描述

我收到这个错误。据我所知，它需要配置 webpack 文件，但在这个 rails 应用程序中，它是一个 webpacker.yml 文件。使用通常的标签时，CRA 看起来工作正常。任何帮助，将不胜感激。

./app/javascript/components/User/cover.mp4 1:0 Module parse failed: Unexpected character '' (1:0) 您可能需要适当的加载程序来处理此文件类型，目前没有配置加载程序来处理此文件. 请参阅https://webpack.js.org/concepts#loaders（此二进制文件省略了源代码）

解决方案

在下添加config/webpacker.yml_static_assets_extensions.mp4

static_assets_extensions
  - .mp4
  ...

新建一个文件夹app/javascripts/static

然后

const file = require('static/file.mp4')

render() {
  return (
    <div>
      <video controls>
        <source src={file} />
      </video>
  ...

注意：您应该使用 CDN 传送视频
