public async Task<int> PostServiceint(string UR, object obj)
{
int bln = 0;
try
{
foreach (var prop in obj.GetType().GetProperties())
{
Console.WriteLine($"{prop.Name}: {prop.GetValue(obj)}");
}
HttpClientHandler handler = new HttpClientHandler
{
// ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator
ServerCertificateCustomValidationCallback = (message, cert, chain, errors) => true
};
using (var client = new HttpClient(handler))
{
client.Timeout = TimeSpan.FromMinutes(10);
Console.WriteLine(obj.ToString());
var response = client.PostAsJsonAsync(UR, obj).Result;
var data = response.Content.ReadAsStringAsync().Result;
Console.WriteLine(response);
if (response.IsSuccessStatusCode)
{
string JsonString = response.Content.ReadAsStringAsync().Result;
bln = Convert.ToInt32(JsonString);
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
return bln;
}
