POST with no data doesn't work

[DanielSundberg]

I have the following API-method:

[Route("api/xyz")]
[HttpPost]
public IHttpActionResult PostAPIXYZ() {
    return Ok("ok");
}

Then calling it with:

using PainlessHttp.Http;

var config = new Configuration {
     BaseUrl = "http://localhost:81",
};

HttpClient = new HttpClient(config);    
var result = HttpClient.PostAsync<MyResult>("api/xyz", null).Result;

Result: Http status: LengthRequired (411)

In powershell it works ok:

> (Invoke-WebRequest http://localhost:81/api/xyz -Method POST).StatusDescription
OK

Using Http client from System.Net.Http works ok:

using System.Net.Http;

HttpClient HttpClient = new HttpClient {
    BaseAddress = new Uri(http://localhost:81), 
};
var result = HttpClient.PostAsync("api/xyz", new StringContent(""))

Hi @DanielSundberg, Thanks for reporting this. PainlessHttp has not been updated for some time, one reason is that it's based on HttpRequester, which is discontinued in dotnet core.

Anyways, I believe that the problem is that you're in fact sending a POST body, the (empty) StringContent. It will eventually get serialized. You could try string.Empty or try the method PerformRaw that does not require you to specify any body.

Hope this helps!

string.Empty doesn't work.

HttpClient.PerformRawAsync(HttpMethod.Post, "api/xyz") with no data still gives me Http status LengthRequired.

Using System.Net.Http.HttpClient for now.
