Javascript 使用webpack脱机插件从服务工作者中排除URL
我目前正在使用AWS Cloudfront在同一个域上设置2个应用程序,以管理应用程序之间的路由。这两个应用程序中的一个是React应用程序,它基于React样板文件,使用离线插件设置服务人员。默认情况下,react应用程序的路由在Cloudfront中被列为白名单,回退路由是其他应用程序的路由(例如/blog) 问题来自React应用程序的服务人员,他们在调用另一个应用程序的路由时返回默认404 我猜我的url应该重定向到另一个应用程序,基于Cloudfront重定向(例如/blog,它是wordpress)被服务人员截取,然后从主应用程序返回404 我尝试了webpack离线插件提供的一些选项,但我对服务人员的理解不是最佳的。。。 我尝试过使用Javascript 使用webpack脱机插件从服务工作者中排除URL,javascript,reactjs,webpack,service-worker,react-boilerplate,Javascript,Reactjs,Webpack,Service Worker,React Boilerplate,我目前正在使用AWS Cloudfront在同一个域上设置2个应用程序,以管理应用程序之间的路由。这两个应用程序中的一个是React应用程序,它基于React样板文件,使用离线插件设置服务人员。默认情况下,react应用程序的路由在Cloudfront中被列为白名单,回退路由是其他应用程序的路由(例如/blog) 问题来自React应用程序的服务人员,他们在调用另一个应用程序的路由时返回默认404 我猜我的url应该重定向到另一个应用程序,基于Cloudfront重定向(例如/blog,它是wo
