HttpClient Returns 404 not found - xamarin

Question

I have a xamarin app that pull data from a webAPI. I check api address so many times and i am sure it is correct. When i debug my code i have 404 not found error from server. However when i copy and paste the URL to browser i have expected result. I couldn't figure out why my app return 404.
My Method:
public async Task<ICustomerType> GetById(int id)
{
string _token;
if (App.Current.Properties.ContainsKey("token"))
{
_token = (string)App.Current.Properties["token"];
}
else
{ _token = null; }
var webApiResponse =
_connector.PostAsync(
"api/Customer/get/id/" + id,
string.Empty, _token).Result;
var response = webApiResponse.Result.ToString();
var jObjectResponse = JObject.Parse(response);
ICustomerType customerTypeObj = null;
return customerTypeObj;
}
My bridge method to HttpClient's PostAsync method:
private async Task<TResponse> PostAsync(string requestPath, string
jsonContent, bool getToken, string token)
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(_apiUrl);
client.DefaultRequestHeaders.Accept.Clear();
var contentType = new MediaTypeWithQualityHeaderValue("application/json");
client.DefaultRequestHeaders.Accept.Add(contentType);
if (getToken)
{
token = GetApiTokenAsync().Result;
}
if (!string.IsNullOrEmpty(token))
{
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + token);
}
var httpContent = new StringContent(jsonContent, Encoding.UTF8, "application/json");
var response = client.PostAsync(requestPath, httpContent).Result;
var jsonData = await response.Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject<TResponse>(jsonData);
}
Token: Correct
API Url: Correct(I check "/" signs from debug output.They are well placed. My Api like:
https://MyApi.net/api/Personel/get/id/1)
My Error:
response {StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.StreamContent, Headers: { Request-Context:
appId=cid-v1:Some_String Server: Kestrel

Answer 1

your method verb in API is "GET" but you used "POST" in the client So in browser works because browser call "GET", but in the client doesn't work.
instead of :
var webApiResponse =
_connector.PostAsync(
"api/Customer/get/id/" + id,
string.Empty, _token).Result;
use :
var webApiResponse =
_connector.GetAsync(
"api/Customer/get/id/" + id,
string.Empty, _token).Result;
