How to add token to request header in ASP.NET Core-CodePudding

I have an API secured by a bearer token. The API has two controllers, one is the default WeatherForecast and the second one is for handling CRUD operations for player model. I decided to get my token from WeatherForecast and use it to call player in my MVC project.

But when I start debugging, it shows Unauthorized for response in every MVC action. It's ok on using postman though.

Here are the controller methods for HttpGet and HttpPost:

namespace MyMVCProject.Controllers
{
    public class HomeController : Controller
    {
        private readonly ILogger<HomeController> _logger;
        private readonly IHttpClientFactory _clientFactory;
        
        public HomeController(ILogger<HomeController> logger, IHttpClientFactory clientFactory)
        {
            _logger = logger;
            _clientFactory = clientFactory;
        }
        
        public async Task<IActionResult> Index()
        {
            var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost:42045/weatherforecast/");
            var client = _clientFactory.CreateClient();
            HttpResponseMessage response = await client.SendAsync(request);

            if (response.StatusCode == System.Net.HttpStatusCode.OK)
            {
                string token = await response.Content.ReadAsStringAsync();
                HttpContext.Session.SetString("JwtToken", token);
            }
        
            return View();
        }

        public async Task<IActionResult> GetAllPlayers()
        {
            var accessToken = HttpContext.Session.GetString("JwtToken");
            List<Player> players = new List<Player>();
            var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost:42045/api/player");

            var client = _clientFactory.CreateClient();

            request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
            HttpResponseMessage response = await client.SendAsync(request, HttpCompletionOption.ResponseHeadersRead);

            if (response.StatusCode == System.Net.HttpStatusCode.OK)
            {
                var apiString = await response.Content.ReadAsStringAsync();
                players = JsonConvert.DeserializeObject<List<Player>>(apiString);
            }

            return View(players);
        }

        [HttpPost]
        public async Task<IActionResult> AddPlayer(Player player)
        {
            var accessToken = HttpContext.Session.GetString("JwtToken");
            var request = new HttpRequestMessage(HttpMethod.Post, "http://localhost:42045/api/player/");

            if (player != null)
            {
                request.Content = new StringContent(JsonConvert.SerializeObject(player), System.Text.Encoding.UTF8, "application/json");
                request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
            }
            else
            {
                return BadRequest();
            }

            var client = _clientFactory.CreateClient();

            HttpResponseMessage response = await client.SendAsync(request, HttpCompletionOption.ResponseHeadersRead);

            if (response.StatusCode == System.Net.HttpStatusCode.Created)
            {
                var apiString = await response.Content.ReadAsStringAsync();
                player = JsonConvert.DeserializeObject<Player>(apiString);
                TempData["success"] = "Player Added Successfully!";
            }
            else if (response.StatusCode == System.Net.HttpStatusCode.BadRequest)
            {
                TempData["badrequest"] = "Player with the same name already exists";
            }

            return View(player);
        }
    }
}

CodePudding user response：

HttpRequestMessage has a Headers property of type HttpRequestHeaders. This class has two Add methods you can use.

You can add headers like this:

request.Headers.Add("Authorization", "Bearer "   YourToken);

CodePudding user response：

I am using this syntax

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
