POST to ASP.NET Web API from Fiddler

I have an ASP.NET Web API. I am trying to POST a string to an endpoint. My ASP.NET Web API endpoint looks like the following:

[HttpPost]
public async Task<IHttpActionResult> Test(string name)
{
  int i = 0;
  i = i + 1;
  return Ok();
}

In Fiddler, I execute the following request from the composer:

POST http://localhost:8089/api/MyApiController/test

If I remove "string name" as the parameter, I can successfully execute my API endpoint. When string name is there, I get a 405 error. So, I added the following in the "Request Body" section in Fiddler:

John

Unfortunately, that still causes a 405 to be thrown. I can't tell if I'm setting up my Web API endpoint wrong if I'm setting up my request in fiddler incorrectly. My full request looks like this:

POST http://localhost:8089/api/MyApiController/test HTTP/1.1
User-Agent: Fiddler
Host: localhost:8089
Content-Length: 26
Content-Type: application/json; charset=utf-8        

{ "name" : "John"}

The response looks like this:

HTTP/1.1 405 Method Not Allowed
Cache-Control: no-cache
Pragma: no-cache
Allow: GET
Content-Type: application/json; charset=utf-8
Expires: -1
Server: Microsoft-IIS/8.0
X-SourceFiles: =?UTF-8?B?QzpcRWNvZmljXFNvbGlkUVxKTExcamxsLW1hcmtldHNwaGVyZVxXZWJzaXRlXGFwaVxTZWFyY2hBcGlcaW5kZXg=?=
X-Powered-By: ASP.NET
Date: Fri, 12 Dec 2014 15:51:50 GMT
Content-Length: 73

{"Message":"The requested resource does not support http method 'POST'."}

I don't understand why POST is allowed when I do not have a parameter. Yet, when I add a parameter, POST does not work.

[Update] I added the following in my C# code:

var content = await Request.Content.ReadAsStringAsync();

I figured the JSON would be in the content. However, content is just an empty string.

Under the "Composer" tab:

enter image description hereI suggest you should try with following url

http://localhost:8089/api/MyApi/test

I think that problem is with route.

You should have some route like following as default route just have controller/id. This route comes before default route.

config.Routes.MapHttpRoute(
                name: "DefaultApi1",
                routeTemplate: "api/{controller}/{action}",
                defaults: new { action="test" }
            );

Also you action should look like this.

[HttpPost]
public async Task<IHttpActionResult> Test([Frombody]string name)
{
  int i = 0;
  i = i + 1;
  return Ok();
}

Below, I modified the datatype of the parameter from string to object, and had success.

public async Task<IHttpActionResult> Post( [ FromBody ] **object** items )
{
    Console.WriteLine( items );
    return Ok();
}

In the body you need to add Json or XML syntax, not just then name for The Asp.Net Deserialiser to do its thing. Json would be:

{ "name" : "John" }

EDIT: Your url route also seems incorrect, if you are using the default routes. By default it will be picked up as: POST http://localhost:8089/api/MyApiController/ the "test" part is omitted as it recognises this as a POST method. Your action should also specify that the parameter you take in ("name") is expected from the body public async Task<IHttpActionResult> Test([FromBody]string name). Now your url will match if you do something like:

`POST http://localhost:8089/api/MyApiController/`
User-Agent: Fiddler
Host: localhost:8089
Content-Length: 26

{ "name" : "John" }
