打包发布到 Serverless 后，控制台报以下问题：

Service Worker SUPPORTED. ERROR DOMException: 
Failed to register a ServiceWorker: The origin of the provided scriptURL ('https://aaaa.com') does not match the current origin ('https://bbbb.com').

问题原因

Service Worker 文件在他域名的 CDN 服务器上，跨域注册 Service Worker 不允许

解决方案

  • 新增配置 serviceWorker.publicPath，用以配置 Service Worker 文件访问前缀
    • 该配置默认为 /，即通过本域访问
  • Service Worker 文件也输出到服务器打包结果中
  • 服务器响应到 Service Worker 文件请求时，从服务器端结果中读取文件并返回
  • Workbox 尝试处理跨域请求的静态资源
    • 通过 Client 的 publicPath 判断是否是打包的
