您需要向您的浏览器代码提供请求

app.browser.module.ts

...
// the Request object only lives on the server
export function getRequest(): any {
  return { headers: { cookie: document.cookie } };
}
...

 providers: [
    {
      // The server provides these in main.server
      provide: REQUEST,
      useFactory: getRequest,
    },
    { provide: 'ORIGIN_URL', useValue: location.origin },
  ],
