I'm getting a 404 error when trying to use an HttpClient to connect to a WebApi service using GET. However, POST works without any problem. In the code below, I have a CreditCard class that I use throughout.
Here's my routing configuration:
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
Here's my code that calls the async operation:
Task task1 = RegisterCard(card, false);
Task task2 = FetchCard(cardid, false);
Here's my code that contains the the async operations:
private async Task RegisterCard(CreditCard card, bool runAsync)
{
try
{
using (HttpClient client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:63801/");
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = runAsync
? await client.PostAsJsonAsync("api/card", card)
: client.PostAsJsonAsync("api/card", card).Result;
response.EnsureSuccessStatusCode();
}
}
catch (HttpRequestException ex)
{
throw new HttpRequestException(ex.Message, ex.InnerException);
}
}
private async Task FetchCard(int cardid, bool runAsync)
{
CreditCard card = new CreditCard();
try
{
using (HttpClient client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:63801/");
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = runAsync
? await client.GetAsync("api/card/" + cardid)
: client.GetAsync("api/card/" + cardid).Result;
response.EnsureSuccessStatusCode();
}
}
}
catch (HttpRequestException ex)
{
throw new HttpRequestException(ex.Message, ex.InnerException);
}
}
Here's my code for the apiController:
[HttpPost]
public HttpResponseMessage Register(CreditCard card)
{
HttpResponseMessage result;
try
{
RegisterResponse response = _cardRepository.Register(card);
result = Request.CreateResponse(HttpStatusCode.Created, response);
}
catch (Exception ex)
{
// TODO: add logging
result = Request.CreateErrorResponse(HttpStatusCode.BadRequest, "failed to register card");
}
finally
{
// TODO: add audit logging of what attempted and who attempted it
}
return result;
}
[HttpGet]
public CreditCard Fetch(int cardid)
{
CreditCard card = new CreditCard();
try
{
card = _cardRepository.Fetch(cardid);
}
catch (Exception ex)
{
// TODO: add logging
}
finally
{
// TODO: add audit logging of what attempted and who attempted it
}
return card;
}
And my code for the CardRepository:
public RegisterResponse Register(Models.CreditCard card)
{
using (CreditCardContext ccContext = new CreditCardContext())
{
card.MaskedNumber = "XXXXXXXXXXXX" + card.Number.Substring(card.Number.Length - 4, 4);
card.Number = Crypto.EncryptData_Aes(card.Number, KeyType.CardNumberKey);
card.CardGuid = Guid.NewGuid().ToString();
ccContext.CreditCards.Add(card);
ccContext.SaveChanges();
}
card.ResetSensitive();
RegisterResponse response = new RegisterResponse
{
IsSuccess = true,
Message = "successfully registered card",
CreditCard = card
};
return response;
}
public CreditCard Fetch(int cardid) // , bool masked
{
CreditCard card;
using (CreditCardContext ccContext = new CreditCardContext())
{
card = ccContext.CreditCards.SingleOrDefault(x => x.Card_ID == cardid);
}
return card;
}
QUESTION: Why am I getting a 404 error when using an HttpClient object to connect to my WebApi service using HttpGet, but when I use HttpPost, it works correctly?
