You can do this like that

import {ActivatedRoute} from '@angular/router';
...

constructor(private route:ActivatedRoute){}
dicountCode:string;

ngOnInit(){
    this.dicountCode = this.route.snapshot.params['dicountCode'];
}

If you want to access query params you can do it in the following way

this.route.snapshot.queryParamMap.get('dicountCode');
