Post an empty body to REST API via HttpClient

The API I'm trying to call requires that I do a POST but with an empty body. I'm new to using the WCF Web API HttpClient and I can't seem to find out the write code that would do a post with an empty body. I find references to some HttpContent.CreateEmpty() method, but I don't think that is for the Web API HttpClient code since I can't seem to find that method.

Solution 1:

Use StringContent or ObjectContent which derive from HttpContent or you can use null as HttpContent:

var response = await client.PostAsync(requestUri, null);

Solution 2:

Did this before, just keep it simple:

Task<HttpResponseMessage> task = client.PostAsync(url, null);

Solution 3:

Have found that:

Task<HttpResponseMessage> task = client.PostAsync(url, null);

Adds null to the request body, which failed on WSO2. Replaced with:

Task<HttpResponseMessage> task = client.PostAsync(url, new {});

And worked.

Solution 4:

To solve this problem, use this example:

   using (var client = new HttpClient())
            {
                var stringContent = new StringContent(string.Empty);
                stringContent.Headers.ContentType = MediaTypeHeaderValue.Parse("application/x-www-form-urlencoded");
                var response = client.PostAsync(url, stringContent).Result;
                var result = response.Content.ReadAsAsync<model>().Result;
            }
