Angular 7 - Service Worker 未注册 [英] Angular 7 - service worker not registered

问题描述

我按照https://angular.io/guide/service-worker-getting-started" 使我的应用程序成为 PWA.

I did everything as written in "https://angular.io/guide/service-worker-getting-started" to make my application PWA.

正是使用了这个命令:

ng add @angular/pwa

npm install http-server -g

ng build --prod

http-server -p 8080 -c-1 dist

然后我在 Chrome 上打开了这个网址(隐身)

Then I opened this url on Chrome (in incognito)

http://127.0.0.1:8080

当我打开面向开发人员的工具 (f12) > 应用程序 > Service Workers 时，没有可用的 Service Worker，当我在那里设置离线时，网站也无法工作.

When I open tools for developers (f12) > Applications > Service Workers there is no service worker available and website don't work when I set offline there.

有关我的 Angular 应用的其他信息:

推荐答案

@angular/cli@7.1.4 的 service worker 设置似乎已损坏:

It seems the service worker setup is broken for the @angular/cli@7.1.4:

作为临时解决方案，您可以通过修改文件 src/main.ts 自行手动注册(一旦修复，您可以删除手动 Service Worker 注册.):

As a temporary solution you can register it manually yourself by modifying the file src/main.ts (Once fixed you can remove the manual service worker registration.):

.....

platformBrowserDynamic().bootstrapModule(AppModule).then(() => {
  if ('serviceWorker' in navigator && environment.production) {
    navigator.serviceWorker.register('/ngsw-worker.js');
  }
}).catch(err => console.log(err));
