type RestClient interface {
	Call(requestBuilder gorequestbuilder.RequestBuilder) (*http.Response, error)
}

type restClientImpl struct {
	baseURL string
	client *http.Client
}

func NewRestClient(baseURL string, client *http.Client) RestClient {
	return &restClientImpl{
		baseURL: baseURL,
		client: client,
	}
}

func (r restClientImpl) Call(requestBuilder gorequestbuilder.RequestBuilder) (*http.Response, error) {
	request, err := requestBuilder.SetBaseURL(r.baseURL).Build()
	if err != nil {
		return nil, errors.New("Build request error: " + err.Error())
	}

	return r.client.Do(request)
}

func main() {
	restClient := NewRestClient("http://0.0.0.0:8080", &http.Client{})

	requestBuilder := gorequestbuilder.NewRequestBuilder().SetMethodGet().SetPath("/v1/foo")

	response, err := restClient.Call(requestBuilder)
	if err != nil {
		fmt.Println("Error while trying to call from rest client: " + err.Error())
		return
	}

	defer response.Body.Close()
	body, err := ioutil.ReadAll(response.Body)

	fmt.Println("[status: " + response.Status + "] - [body: " + string(body) + "]")
