A LocationStrategy
used to configure the Location
service 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_HREF
or 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
.
Example
import {Location, LocationStrategy, PathLocationStrategy} from '@angular/common'; import {Component} from '@angular/core'; @Component({ selector: 'path-location', providers: [Location, {provide: LocationStrategy, useClass: PathLocationStrategy}], 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> ` }) export class PathLocationComponent { location: Location; constructor(location: Location) { this.location = location; } }方法
