Angular2中如何获取GET参数？

通过访问myproject.dev/people?filter%5Bindustry%5D=finance&filter%5BstartWith%5D=a, Angular2将url指向myproject.dev/people

这是我的路线配置：

@RouteConfig([
    {
        path: '/people',
        name: config.route.main,
        component: MainComponent,
        useAsDefault: true
    }
])

在主要组件中：

/// <reference path="../../../typings/angular2.d.ts" />

import {Component, Injector} from 'angular2/core';
import {ROUTER_DIRECTIVES, Router, RouteParams} from 'angular2/router';
import {BaseResourceComponent} from '../../Component/BaseResourceComponent';
import {Status as MainStatus} from '../../reusable/modules/status.svc';

import {Status} from '../../reusable/modules/status.svc';
import {Config} from "./Config";

import URI from 'urijs';

export class MainComponent extends BaseResourceComponent {
    constructor(config: Config, status: Status, mainStatus: MainStatus, private router: Router, private routeParams: RouteParams) {
        super(config, status, mainStatus);
    }

    onInit() {
        var path = new URI(window.location.href);
        path.setQuery('filter[industry]', 'fashion');
        path.setQuery('filter[startWith]', 'a');

        console.log(path);
        console.log(this.router);
        //this.router.root.lastNavigationAttempt = "/people?filter%5Bindustry%5D=finance&filter%5BstartWith%5D=a"

        console.log(this.routeParams);
        // this.routeParams returns {params: Object}
        // this.routeParams.params.get('filter') return null
    }
}

我仍然可以从this.router.root.lastNavigationAttempt，但这只是获取它的一种棘手方法。有更好的方法获取 GET 参数吗？

在根组件中，您可以注入路由器并订阅，然后在路由事件上从路由器获取参数，例如

export class AppComponent {
  constructor(private router:Router) {
    router.subscribe(route => {
      console.debug(this.router.currentInstruction.component.params);
    });
  }
}

在路由器添加的组件上，您可以注入RouteParams直接喜欢

export class Other{
    constructor(private routeParams: RouteParams) {
    console.debug(this.routeParams);
    console.log(this.routeParams.get('filter_industry'));
    console.log(this.routeParams.get('filter_start_with'));
  }
}
