Support for query params array

[thebrownfox]

When I try to use array in query parameters, I get this validation error. I think it's because it doesn't check against "search_fields[index]" (search_fields only).

ValidationError: "search_fields[0]" is not allowed

"search_fields": {
    "name": "search_fields",
    "in": "query",
    "schema": {
        "items": {
            "type": "string"
        },
        "type": "array"
    }
}

value:

{
  search: "",
  "search_fields[0]": "id",
  results: "10",
  page: "1",
  "sort[0]": "id",
  "sort[1]": "asc",
}

Ok, my bad. For anyone who cannot find out why it's not working, you need to parse the params beforehand.

const server = new Hapi.Server({
    query: {
        parser: (query) => qs.parse(query),
    },
});
