I am calling the web API methods from my client project and returning the value from response header to client:
[HttpPost]
[AllowAnonymous]
[Route("login")]
public IActionResult Login(Users user)
{
string s = _repository.Users.ValidateUser(user);
if (s == "success")
{
Users u = _repository.Users.FindByUserName(user.UserName);
int pid = u.PersonId;
string role = "";
if (u != null)
{
role = _repository.RoleManager.GetRole(u.Id);
}
Response.Headers.Add("Role", role);
return Ok(pid.ToString());
}
}
And I tried the code below for getting header value in the client application:
[HttpPost]
public IActionResult Login(Users user)
{
string pid = "";
HttpClient client = service.GetService();
HttpResponseMessage response = client.PostAsJsonAsync("api/mymethod", user).Result;
Task<string> tokenResult = response.Content.ReadAsAsync<string>();
pid = tokenResult.Result.ToString();
var headers = response.Headers;
string role = "";
if (headers.TryGetValues("Role", out IEnumerable<string> headerValues))
{
role = headerValues.ToString();
}
return RedirectToAction("Profile");
}
But it returns System.String[]
.
Please show me the right way for fetching data from the response header.
I found the solution:
var headers = response.Headers;
string role = "";
if (headers.TryGetValues("Role", out IEnumerable<string> headerValues))
{
role = headerValues.FirstOrDefault();
}
Don't forget to add a reference to System.Linq
.
