无法使用特殊字符访问Angular2 Route参数

Question

这是我访问路线list/hg76hjb.hhuh67.878hhuu

的路线参数的组件

import {ActivatedRoute} from '@angular2/router';

export class FooComponent {
constructor(private route: ActivatedRoute) {}
    ngOnInit() {
     this.route.params.subscribe((params:any) => {
     this.token = +params['token'];
    });
  }

}

这是我的app-routing.module.ts

{path: 'list/:token', component: FooComponent}

list/gfhg76.ghfhg6 - 我收到错误Cannot GET list/gfhg76.ghfhg6

list/hgjjhk - this.token正在获得正确的价值，即hgjjhk

请帮我提取整个令牌gfhg76.ghfhg6
