Angular2-没有路由的位置？

Question

如何在没有路由的情况下监视和设置URL搜索参数？

'地点'，似乎有我想要的。不过，我得到这个错误：

Error: No provider for Location!

下列要求：

import { Component } from '@angular/core'; 
import { Location, HashLocationStrategy } from "@angular/common"; 

@Component({ 
    selector: 'app-root', 
    templateUrl: 'app.component.html', 
    styleUrls: ['app.component.css'], 
    providers: [HashLocationStrategy] 
}) 

export class AppComponent { 
    constructor(private location: Location){} 
} 

我怎么知道它想要哪个供应商？还有更好的方法来完成这个吗？

我做了一次。要实现HashLocationStrategy你必须实现它一样，在你的MainComponent：

import {bootstrap} from '@angular/platform-browser-dynamic'; 
import { 
    Location, 
    LocationStrategy, 
    HashLocationStrategy, 
    APP_BASE_HREF 
} from '@angular/common'; 
import {provide} from '@angular/core'; 
import {ROUTER_PROVIDERS} from '@angular/router-deprecated' 

import { HTTP_PROVIDERS } from '@angular/http'; 
import {AppComponent} from './app.component'; 

bootstrap(
    AppComponent 
    , [ 
     HTTP_PROVIDERS 
     ,ROUTER_PROVIDERS 
     , provide(APP_BASE_HREF, { useValue: '/' })  
     , provide(LocationStrategy, { useClass: HashLocationStrategy })] 
);
