Question

I want to post an object using an API call. I’m getting the data using the following code in my codebehind

 HttpClient client = new HttpClient();

 client.BaseAddress = new Uri(ConfigurationManager.AppSettings["JUri"]);
 client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));


 HttpResponseMessage response = client.GetAsync("api/receipt/" + jID).Result;
 if (response.IsSuccessStatusCode)
 {}

I would like to know there is any code equivalent to POST for this.

Answer 1

POST using Form:

HttpClient client = new HttpClient();
client.BaseAddress = new Uri(ConfigurationManager.AppSettings["JUri"]);

var postData = new List<KeyValuePair<string, string>>();

postData.Add(new KeyValuePair<string, string>("Key1", "Value1"));
postData.Add(new KeyValuePair<string, string>("Key2 ", "Value2"));

HttpContent content = new FormUrlEncodedContent(postData);
var response = client.PostAsync("api/receipt/" + jID, content)
if (response.IsSuccessStatusCode)
{}

POST using JSON, assume you have Dto class:

var client = new HttpClient();
var dto = new Dto {Pro1 = "abc"};

var reponse = client.PostAsJsonAsync("api/receipt/" + jID, dto).Result;

if (reponse.IsSuccessStatusCode)
{}
