using Newtonsoft.Json;
using WebApiApp.Models;

namespace WebApiApp;

public class UserFacade : IUserFacade
{
    private readonly IHttpClientFactory _httpClientFactory;

    public UserFacade(IHttpClientFactory httpClientFactory)
    {
        _httpClientFactory = httpClientFactory;
    }

    public async Task<IEnumerable<User>> GetAll()
    {
        var httpClient = GetHttpClient();
        var response = await httpClient.GetAsync("users");
        var body = await response.Content.ReadAsStringAsync();

        return JsonConvert.DeserializeObject<List<User>>(body);
    }

    private HttpClient GetHttpClient()
    {
        return _httpClientFactory.CreateClient("UsersService");
    }
}
