        .queryParams
        .subscribe(params => {

        });

Answer 1

您应该注入ActivatedRoute来获取路由参数,如下所示,

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
});
