PathLocationStrategy
此 LocationStrategy用来配置 Location服务，以便在浏览器 URL 的 path 中表示其状态。
A LocationStrategyused to configure the Locationservice to represent its state in the path of the browser's URL.
class PathLocationStrategy extends LocationStrategy implements OnDestroy {
ngOnDestroy(): void
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
historyGo(relativePosition: number = 0): 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
historyGo(relativePosition: number)?: void
abstract onPopState(fn: LocationChangeListener): void
abstract getBaseHref(): string
}
说明
如果你使用 PathLocationStrategy ，则必须提供一个 APP_BASE_HREF或在文档中添加 <base href>。
If you're using PathLocationStrategy, you must provide a APP_BASE_HREFor add a <base href> element to the document.
例如，如果你提供的 APP_BASE_HREF 是 '/my/app/'，并调用 location.go('/foo')，则浏览器的 URL 将变为 example.com/my/app/foo。为了确保所有相对 URI 都能正确解析，<base href> 和/或 APP_BASE_HREF 都应该以 / 结尾。
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. To ensure all relative URIs resolve correctly, the <base href> and/or APP_BASE_HREF should end with a /.
同样，如果将 <base href='/my/app/'/> 添加到文档中并调用 location.go('/foo') ，则浏览器的 URL 将变为 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.
请注意，使用 PathLocationStrategy 时，如 RFC 所述，查询和 <base href> 的片段部分都不会保留。
Note that when using PathLocationStrategy, neither the query nor the fragment in the <base href> will be preserved, as outlined by the RFC.

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;
