推荐答案

您应注入 ActivatedRoute 以获得 route params ，如下所示，

You should inject ActivatedRoute to get route params as shown below,

constructor(private router: Router,
    private userService: UserService,
    private route: ActivatedRoute,) {  //<----- here

    this.route.params.subscribe(params => {
            this.id = +params['id'];   //<----- + sign converts string value to number
});
