Hi,

I'm trying to POST to my WebAPI server unsuccessfully. What is wrong with this code? I've tested this Web API using Postman am,d it's ok. Here is my code.

                // Send Fire Event to PMK
                HttpClient client = new HttpClient();
                client.BaseAddress = new Uri("http://192.168.151.100:8080/");
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(
                    new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

                var serialize = JsonConvert.SerializeObject(fireEvent);
                var response = await client.PostAsync("api/FireEvents", 
                    new StringContent(serialize, Encoding.Unicode, "application/json"));

Thank you soo much

Hi jsiahaan,

You can refer the following code.

HttpClient:

            using (var client = new System.Net.Http.HttpClient())
            {
                // HTTP POST
                var baseUrl = Request.Url.GetLeftPart(UriPartial.Authority);
                client.BaseAddress = new Uri(baseUrl);
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
  
                var content = new StringContent(JsonConvert.SerializeObject("Test"), Encoding.UTF8, "application/json");
                var response = client.PostAsync("/api/Values", content).Result;
                string s = await response.Content.ReadAsStringAsync();
            }

Hi all,

Thanks for replies.

It was my IIS setting incorrectly. I did not set ASP.NET 4.6.
