Could not find the controller end point when passing a string as a parameter in Web API 2 put as async

Code for controller

[Authorize]
[HttpPut]
[Route("TopHandler/{studentId}")]
public async Task<HttpResponseMessage> CreateClass(string studentId, String projectId)
{
    var response = await Task.Run(() =>
    {
        //  Some Code here
    });

    return response;
}

Code for Controller call 

 await VML.Client.PutAsJsonAsync("TopHandler/" + studentId, projectId);

Unfortunately this end point cannot be found by the request and it gives 404 I am passing a string as a parameter . What would possibly go wrong here ?

Solution

  • My understanding is when you call PutAsJsonAsync the parameters are converted to JSON and sent in the BODY of the request.

    At a guess you should change your signature to:

    [Route("TopHandler/{studentId}")]
public async Task<HttpResponseMessage> CreateClass([FromBody]string JSON)
