Angular2 - 带有HashLocationStrategy的APP_BASE_HREF

Question

我有一个角度应用程序使用路由与HashLocationStrategy,我需要在主html文件中设置不同的值和路由不同.

我试过这个解决方案:

@NgModule({
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule,
        MyRouting // with useHash set to true
    ],
    declarations: [
        AppComponent,
    ],
    providers: [
        { provide: APP_BASE_HREF, useValue: '/prefix' }
    ],
    bootstrap: [AppComponent]
})
export class AppModule { }

工作得很好,但值'/ prefix'是在哈希后插入,如下所示:

http://myapp.com/#/prefix/home

我想要的是:

http://myapp.com/prefix/#/home

为清楚起见,我的基本标签是:

<base href="/">

我遇到了同样的问题,用我自己的HashLocationStrategy子类修复了它

import { Injectable } from '@angular/core';
import { HashLocationStrategy } from '@angular/common';

@Injectable()    
export class CustomLocationStrategy extends HashLocationStrategy {
    prepareExternalUrl(internal: string): string {
        return this.getBaseHref() + '#' + internal;
    }
}

然后在我的模块中使用它

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { LocationStrategy } from '@angular/common';
import { APP_BASE_HREF } from '@angular/common';
import { CustomLocationStrategy } from './app.common';

const appRoutes: Routes = [...];

@NgModule({
    imports: [
        RouterModule.forRoot(appRoutes, { useHash: true })
    ],
    providers: [
        { provide: APP_BASE_HREF, useValue: window.location.pathname },
        { provide: LocationStrategy, useClass: CustomLocationStrategy },
    ]
})
export class AppModule {
}
