sending array as a query param in angular post request

I have the following angular post request :

this._http.post(
        RESOURCE_URL, // my query URL
        {
          params : {
            houses: ids
          }
        }
      );

the variable ids is an array of numbers that I send to the back end, with ids = [1,2] for instance.
my issue is, as I send my request, it is sent as the following RESOURCE_URL?houses=1&houses=2, which is not what I want.

I’m trying to have it more like this : RESOURCE_URL?houses=[1,2].

Now one may suggest why I don’t just pass it on to the request body. Problem is, for prject-specific reasons, I cannot. Too much work would be required and I do not have power to decide whether I should dive into it or not.

is there anyway this can be done ? because haveing looked at this topic and also this one, and it seems like it’s just not possible.

>Solution :

It’s possible, it’s just not the way Angular does this. So, just do it manually.

this._http.post('my_url', {
  params: {
    houses: `[${ids.join(',')}]`
  }
})
