<a routerLink="/post?id=1">
  Link
</a>

I want to navigate in other links with params using routerLink

Use [queryParams] in adition to routerLink as explained in this post How to pass query parameters with a routerLink

Answer 2

you should use

<a [routerLink]="['/post']" [queryParams]="{ id: 1 }">View post</a>

Answer 3

In your particular example you'd do the following routerLink:

    <a [routerLink]="['/post']" [queryParams]="{id: '1'}" queryParamsHandling="preserve"> Link
</a>

id can be variable as well.
