如何从URL（路由）Angular 2获取参数？

Question

I tried to do that in ngOnInit() like:

ngOnInit() {
    this.route.queryParams
      .filter(params => params.type)
      .subscribe(params => {
        this.tab = params.type;
        this.setHeader();
      });
  }

My URL is:

http://localhost:4200/s/6/t/p/create/1

Routing is:

{path: ':Id/t/p/create/:type', component: CalendarComponent},

Answer 1

try that :

this.route.snapshot.params["page"]

the page is the query param so the route must be like that

const routes: Routes = [
  {
    path: 'page/:page',
    component: OrdersComponent,
    data: {
      title: 'Orders'
    }
  }
]

don't forget the add the route into the constructor

constructor(private route: ActivatedRoute) { }

and the import

import {ActivatedRoute} from "@angular/router";

Answer 2

Try

this.route.params.subscribe(params => {
    this.tab = params.type;
    this.setHeader();
  });
