LocationStrategy
LocationStrategy is responsible for representing and reading route state from the browser's URL. Angular provides two strategies: HashLocationStrategyand PathLocationStrategy.
abstract class 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
This is used under the hood of the Locationservice.
Applications should use the Routeror Locationservices to interact with application route state.
For instance, HashLocationStrategyproduces URLs like http://example.com#/foo, and PathLocationStrategyproduces http://example.com/foo as an equivalent URL.
See these two classes for more.
