How to use arrays in routes with Angular?

The getAll() method returns duplicate parameters as an array.

Example:

http://www.example.com/?query=a&query=b&query=c

The value would be:

console.log(params.getAll('query')); // prints ["a","b","c"]

All query parameters in the HTTP specification are strings.

It works if use routerLink.

But, it's not currently working with your approach.

A bug in Angular's git is already open at https://github.com/angular/angular/issues/19179 for the same. You can track this issue there.
