You can do in this if you want read parameters from URL.

1. First import ActivatedRoute from ‘@angular/router’
2. Inject ActivatedRoute class in constructor.
3. Access queryParams property of ActivatedRoute class which returns an observable of the query parameters that are available in the current URL route.

Example:
import { ActivatedRoute } from '@angular/router';

@Component({ ... })
export class BookComponent implements OnInit {

  orderby: string;

  constructor(private route: ActivatedRoute) { }

  ngOnInit() {
    this.route.queryParams
      .subscribe(params => {
        console.log(params);
        this.claim_doc_code = params.cl_doc_code;
       this.claim_doc_year = params.cl_doc_year;
        this.claim_doc_no = params.cl_doc_no;
      }
    );
  }
}

1. ngOnInit() {
2. combineLatest(
3. this.route.params,
4. this.route.data,
5. (params: Params, data: Data) => ({
6. params,
7. data,
8. })
9. ).subscribe((res: { params: Params; data: Data }) => {
10. const { params, data} = res;
12. this.claim_doc_code = params.cl_doc_code;
15. this.claim_doc_year = params.cl_doc_year;
17. this.claim_doc_no = params.cl_doc_no;
18. });
19. }
let me know if it works.
