//example code
//var lst = await service.ConnectHttpClient<User, List<User>>("api/User/GetUserInfoByUserId", new User() { UserId = 1 });
//var lst = await service.ConnectRestClient<User, List<User>>("api/User/GetUserInfoByUserId", new User() { UserId = 1 });
public async Task<M> ConnectHttpClient<R, M>(string apiUrl, R reqModel)
{
M model = default(M);
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(baseUrl);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await client.PostAsJsonAsync(apiUrl, reqModel);
if (response.IsSuccessStatusCode)
{
var res = response.Content.ReadAsStringAsync().Result;
model = JsonConvert.DeserializeObject<M>(res);
}
return model;
}
public async Task<M> ConnectRestClient<R, M>(string apiUrl, R reqModel)
{
M model = default(M);
RestClient restClient = new RestClient(baseUrl);
RestRequest restRequest = new RestRequest(apiUrl, Method.POST, DataFormat.Json);
restRequest.AddJsonBody(reqModel);
IRestResponse restResponse = await restClient.ExecuteAsync(restRequest);
if (restResponse.IsSuccessful)
