Question

Given a new Asp.Net MVC 4 Web Api application, which has the method

public class ValuesController : ApiController
{
    // PUT api/values/5
    public void Put(int id, [FromBody]string value)
    {
        lastval = "b " + value;
    }
}

How do we call this method via httpie? I tried

http PUT localhost:20780/api/values/3 value="test"

which calls the web api method passing the correct id 3, but the value “test” does not arrive, it is null in the call.

Answer 1

Does the controller expect form-encoded data? If yes, then you need to use the --form, -f option. It’s because HTTPie sends JSON by default:

http --form PUT localhost:20780/api/values/3 value="test"
