I am trying to implement web sockets in my application that currently implements a RESTful web API. I want certain pieces of information to be able to be exposed by a web socket connection so I am trying to figure out how to upgrade a normal HTTP request to a web socket connection.
I am trying to follow this tutorial
The problem I am having is my controller that handles the Get request inherits from ApiController and I am trying to do this:
if (HttpContext.Current.IsWebSocketRequest)
{
HttpContext.Current.AcceptWebSocketRequest(SomeFunction);
}
return new HttpResponseMessage(HttpStatusCode.SwitchingProtocols);
The problem is my HttpContext.Current is always null and I do not know why. It seems like there is no such thing as a HttpContext. I do see however from the request that comes in that their is a HttpRequestContext that comes in with the request. Are these two objects related at all and is there any way I can get access to the .IsWebSocketRequest method so I can try and upgrade the request to a web socket connection?
My controller and what I am trying to do:
[HttpGet]
public HttpResponseMessage GetSomething()
{
if (HttpContext.Current.IsWebSocketRequest()){
Console.WriteLine("web socket request..");
}
}
^ HttpContext.Current is always null. My controller inherits solely from ApiController
To access the Httpcontext in an MVC ApiController, use this code.
if (Request.Properties.ContainsKey("MS_HttpContext")) { HttpContextWrapper HttpContext = (HttpContextWrapper)Request.Properties["MS_HttpContext"]; if (HttpContext != null) { if (HttpContext.IsWebSocketRequest) { HttpContext.AcceptWebSocketRequest(SomeFunction); } } }This will remove the HttpContext from the request if provided.
