PathLocationStrategy
A LocationStrategyused to configure the Locationservice to represent its state in the path of the browser's URL.
class PathLocationStrategy extends LocationStrategy {
onPopState(fn: LocationChangeListener): void
getBaseHref(): string
prepareExternalUrl(internal: string): string
path(includeHash: boolean = false): string
pushState(state: any, title: string, url: string, queryParams: string)
replaceState(state: any, title: string, url: 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
If you're using PathLocationStrategy, you must provide a APP_BASE_HREFor add a base element to the document. This URL prefix that will be preserved when generating and recognizing URLs.
For instance, if you provide an APP_BASE_HREF of '/my/app' and call location.go('/foo'), the browser's URL will become example.com/my/app/foo.
Similarly, if you add <base href='/my/app'/> to the document and call location.go('/foo'), the browser's URL will become example.com/my/app/foo.

template: `
<h1>PathLocationStrategy</h1>
Current URL is: <code>{{location.path()}}</code><br>
Normalize: <code>/foo/bar/</code> is: <code>{{location.normalize('foo/bar')}}</code><br>
