Question

I have MVC-4 Web-API server, and I need to create HTTP client “by hand” (via TCP) to talk with it.

public class UpdateUnitDetailsController : ApiController
{
    // GET api/updateunitdetails
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }

    // GET api/updateunitdetails/5
    public string Get(int id)
    {
        return "value";
    }

    // POST api/updateunitdetails
    public void Post([FromBody]string value)
    {
    }

    // POST api/updateunitdetails
    public void Post()
    {
    }

    // PUT api/updateunitdetails/5
    public void Put(int id, [FromBody]string value)
    {
    }

    // DELETE api/updateunitdetails/5
    public void Delete(int id)
    {
    }
}

I made a simple client and set breakpoints in the server’s controller’s methods. In the client, I send this:

GET /api/updateunitdetails HTTP/1.1
Host: localhost:58743

Content-Type: */*
Content-Length: 10

And it works (the debugger stops in the Get method). But if I change GET to POST, it doesn’t. Moreover, whenever I issue a POST request, I see in the Visual Studio Console this message:

A first chance exception of type 'System.InvalidOperationException' occurred in System.Web.Http.dll

What do I miss ?

Answer 1

Use this instead:

POST /api/updateunitdetails HTTP/1.1
Host: localhost:58743

Content-Type: application/x-www-form-urlencoded
