如何获得当前路线
问题描述：
当前文档仅讨论获取路径参数，而不是实际的路径段.
The current docs only talk about getting route params, not the actual route segments.
例如，如果我想找到当前路线的父级，那怎么可能?
For example, if i want to find the parent of current route, how is that possible?
答
角度RC4:
您可以从@angular/router
然后注入:
constructor(private router: Router ) {
}
然后将其称为URL参数:
Then call it's URL parameter:
console.log(this.router.url); // /routename
