using System.Net.Http;
using System.Net.Http.Headers;
using Newtonsoft.Json;
using System.Text;

namespace ETransportation.Controllers
{
    public class HomeController : Controller
    {
        string api = "http://api.sparrowsms.com/";
        string token = "Random string";
        string from = "Demo";
        [HttpGet]
        public IActionResult Send()
        {
            return View();
        }
        [HttpPost]
        public async Task<IActionResult> Send(SendInfo sendInfo)
        {
            using (var client = new HttpClient())
            {
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept
                    .Add(new MediaTypeWithQualityHeaderValue("application/json"));
                HttpResponseMessage response;

                var parameters = $"token={token}&from={from}" +
                    $"&to={sendInfo.number}&text={sendInfo.message}";

                response = await client.GetAsync(api+ "v2/sms/?"+ parameters);
                response.Content.ReadAsStringAsync().Result;
                if (response.IsSuccessStatusCode)
                {
                    sendInfo.message = “send succefully”;
                    return View(sendInfo);
                }
                else
                {
                     sendInfo.message = “send succefully”;

                    return View();
                }
            }
            
        }
