      class HashLocationStrategy extends LocationStrategy {
  onPopState(fn: LocationChangeListener): void
  getBaseHref(): string
  path(includeHash: boolean = false): string
  prepareExternalUrl(internal: string): string
  pushState(state: any, title: string, path: string, queryParams: string)
  replaceState(state: any, title: string, path: string, queryParams: string)
  forward(): void
  back(): void

  // 继承自 common/LocationStrategy
  abstract path(includeHash?: boolean): string
  abstract prepareExternalUrl(internal: string): string
  abstract pushState(state: any, title: string, url: string, queryParams: string): void
  abstract replaceState(state: any, title: string, url: string, queryParams: string): void
  abstract forward(): void
  abstract back(): void
  abstract onPopState(fn: LocationChangeListener): void
  abstract getBaseHref(): string
}
    

说明

For instance, if you call location.go('/foo'), the browser's URL will become example.com#/foo.
