Expected output

api.FirewallRules and api.Filters calling the public API only once with required params for paginations.

Actual output

They submit at least two requests:

/zones/b1fbb152bbde3bd28919a7f4bdca841f/firewall/rules
/zones/b1fbb152bbde3bd28919a7f4bdca841f/firewall/rules?page=1&per_page=50

Code demonstrating the issue

I've modified cloudflare-go a bit to present the problem I'm seeing. A simple printing out the uri we are calling in cloudflare.go makeRequestContext

func (api *API) makeRequestContext(ctx context.Context, method, uri string, params interface{}) ([]byte, error) {
    fmt.Println(uri)
    return api.makeRequestWithAuthType(ctx, method, uri, params, api.authType)
}

Then when I called in my example code:

fwRules, _, err := api.FirewallRules(context.Background(), cloudflare.ZoneIdentifier("b1fbb152bbde3bd28919a7f4bdca841f"), cloudflare.FirewallRuleListParams{})

stdout follows:

/zones/b1fbb152bbde3bd28919a7f4bdca841f/firewall/rules
/zones/b1fbb152bbde3bd28919a7f4bdca841f/firewall/rules?page=1&per_page=50

References

I found this while I was upgrading cf-terraforming to use the latest cloudflare-go. My tests were not passing, because they needed an additional interaction:
