Why I am getting a 415 response here?

Question

I created the default Web API project using ASP.NET Core. That gave me following controller

[Route("api/[controller]")]
    public class ValuesController : Controller
    {
        // GET api/values
        [HttpGet]
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }

        // GET api/values/5
        [HttpGet("{id}")]
        public string Get(int id)
        {
            return "value";
        }

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

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

        // DELETE api/values/5
        [HttpDelete("{id}")]
        public void Delete(int id)
        {
        }
    }

I am using fiddler to test the api.

When I submit a GET request http://localhost:21674/api/values I get a JSON object with value1 and value2 values

When I try a post to same URL, I get an unsupported media type 415 response as shown below. Click here to see the image

What am I doing wrong?

Answer 1

Your request is forged wrong. There is no application\json mime-type.

The correct mime-type for JSON is application/json (notice the forward slash).

Update

Also you're not allowed to have quotes in it. The final header needs to be: Content-Type: application/json
