FLURL: HTTP POST request in C#

using Flurl;
using Flurl.Http;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        try
        {
            string apiUrl = "https://jsonplaceholder.typicode.com/posts"; // Replace with your API endpoint

            var postContent = new
            {
                userId = 1,
                id = 101, // Replace with the desired ID
                title = "Flurl POST Example",
                body = "This is a simple example of making a POST request using Flurl."
            };

            // Make a POST request using Flurl
            var response = await apiUrl
                .WithHeader("Content-Type", "application/json") // Optional: Set the request header
                .PostJsonAsync(postContent);

            // Check if the request was successful
            if (response.IsSuccessStatusCode)
            {
                var responseBody = await response.Content.ReadAsStringAsync();
                Console.WriteLine("POST request successful. Response:");
                Console.WriteLine(responseBody);
            }
            else
            {
                Console.WriteLine($"POST request failed with status code: {response.StatusCode}");
            }
        }
        catch (FlurlHttpTimeoutException ex)
        {
            Console.WriteLine($"Timeout error: {ex.Message}");
        }
        catch (FlurlHttpException ex)
        {
            Console.WriteLine($"HTTP error: {ex.Message}");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"An error occurred: {ex.Message}");
        }
    }
}        

In this example, we use Flurl to make a POST request to the "https://jsonplaceholder.typicode.com/posts" endpoint (you can replace this URL with your own API endpoint). We provide JSON data in the postContent object, set the "Content-Type" header to "application/json," and use the PostJsonAsync method to send the POST request. We then handle the response, checking for success and printing the response content or any error messages.
