如何在我的Angular2应用程序中@Routes中列出/输出所有路由 [英] How to list / output all routes in @Routes in my Angular2 App

问题描述

我有一个简短的问题.我目前正在通过 https://angular.io/docs/ts/latest/api/router/Router-class.html ，但我想知道，在Angular2的main.ts中，我的路由定义如下:

I have a quick question. I'm currently looking through https://angular.io/docs/ts/latest/api/router/Router-class.html but I was wondering, in my Angular2's main.ts I have my routes defined thus:

@Routes([
    { path: '/', component: HomeComponent },
    { path: '/about-me', component: AboutMeComponent },
    { path: '/food', component: FoodComponent },
    { path: '/photos', component: PhotosComponent },
    { path: '/technology', component: TechnologyComponent },
    { path: '/blog', component:Blogomponent },
])

现在在其他位置的组件中，我导入Router类.在我的组件(或组件模板)中，我想遍历所有定义的路由，或者只是能够访问它们.有内置的方法可以做到这一点吗?像一些返回对象数组的函数一样?这是我想要的一个粗略想法...

Now in a component elsewhere I import the Router class. In my component (or the component template) I would like to loop through all my routes defined or just be able to access them. Is there a built in way to do this? Like some function that returns an object array? Here is a crude idea of what I want...

@Component({
    selector: 'ms-navigation',
    templateUrl: 'src/navigation/navigation.template.html',
    directives: [ ROUTER_DIRECTIVES ]
})

export class NavigationComponent {
    constructor(private router:Router) {   
        // what can I do here to get an array of all my routes?
        console.log(router.routes); ????
    }
}

推荐答案

以下是更好的版本，它将列出所有可能的路线(根据评论进行了固定):

Here is a better version which will list all possible routes (fixed according to comments):

import { Router, Route } from "@angular/router";

constructor(private router: Router) { }

ngOnInit() {
  this.printpath('', this.router.config);
}

printpath(parent: String, config: Route[]) {
  for (let i = 0; i < config.length; i++) {
    const route = config[i];
    console.log(parent + '/' + route.path);
    if (route.children) {
      const currentPath = route.path ? parent + '/' + route.path : parent;
      this.printpath(currentPath, route.children);
    }
  }
}
