Angular中的哈希定位策略2 [英] Hash Location Strategy in Angular 2

问题描述

我正在尝试使用哈希位置策略创建应用程序，但它不会将哈希添加到网址中。例如，当我点击与{path：'/ polls'相关联的按钮，名称：'Polls'，组件：PollsComponent}时，它会使用此url加载页面：localhost：3000 / polls。

I'm trying to create an application with hash location strategy, but it does not add the hash to the url. For instance when I click on a button associated with { path: '/polls', name: 'Polls', component: PollsComponent } it loads the page with this url : localhost:3000/polls.

我需要更改什么才能获得哈希定位策略？
如果我想使用哈希位置策略，为什么我必须设置默认基本网址？

What do I have to change to get the hash location strategy? Why do I have to set the default base url if I want to use hash location strategy?

这是app.component.ts中的路由选择所有路由都已定义：

This is the routing in the app.component.ts where all the routing is defined:

import {Component} from 'angular2/core'

import {HTTP_PROVIDERS, Http} from 'angular2/http';
import 'rxjs/Rx'; // load the full rxjs
import {ROUTER_PROVIDERS, RouteConfig , ROUTER_DIRECTIVES} from  'angular2/router';

import { ResultsComponent } from './results/results.component'
import { VotingCardsComponent } from     './votingcards/votingcards.component'
import { DashBoardComponent } from './dash/dash.component'
import { PollsComponent } from './pollslist/pollslist.component'

@Component({
selector: 'my-app',
templateUrl: 'app/app.component.html',
directives: [ROUTER_DIRECTIVES, ResultsComponent, VotingCardsComponent, DashBoardComponent],
providers: [HTTP_PROVIDERS,
ROUTER_PROVIDERS]
})

@RouteConfig([

    { path: '/vote', name: 'VotePage', component: VotingCardsComponent },
    { path: '/votepoll/:id', name: 'VotePoll', component: VotingCardsComponent },
    { path: '/results', name: 'Results', component: ResultsComponent },
    { path: '/polls', name: 'Polls', component: PollsComponent },
    { path: '/', name: 'DashBoard', component: DashBoardComponent, useAsDefault: true }
])

export class AppComponent { }

这是我的main.ts，我配置基本网址：

And this is my main.ts where I configure the base url:

import {bootstrap}    from 'angular2/platform/browser';
import {AppComponent} from './app.component';

//this is to avoid the href empty issue
import {provide} from 'angular2/core';
import {APP_BASE_HREF, ROUTER_PROVIDERS} from 'angular2/router';

    bootstrap(AppComponent, [
    //this is to avoid the href empty issue
    ROUTER_PROVIDERS,
    provide(LocationStrategy, { useClass: HashLocationStrategy }),
    provide(APP_BASE_HREF, { useValue: '/' })

]);

推荐答案

ROUTER_PROVIDERS 不应添加到子组件，

仅到

providers: [ROUTER_PROVIDERS]

或或仅到

bootstrap(AppComponent, [ROUTER_PROVIDERS]);

HTTP_PROVIDERS 在我看来也更好适合根组件或 bootstrap（）但它不会破坏任何东西以将它们添加到其他地方。

HTTP_PROVIDERS are in my opinion also a better fit for root component or bootstrap() but it doesn't break anything to add them somewhere else.
