Question

I’m using a custom filter to validate the content type, like:

        public override void OnActionExecuting(HttpActionContext httpActionContext)
        {
            List<String> errors = new List<String>();

            // a
            if (httpActionContext.Request.Content.Headers.ContentType.MediaType == "application/json")
            {
            }
            else
            {
                errors.Add("Invalid content type.");
            }

                // more checks
        }

The above code is working fine, but the validation should check the request http verb, because it should validate the content type only for put or post. I don’t want to remove the custom filter from httpget actions because I have more checks inside it, and I don’t want to split the filter in two parts, meaning I have to check the http verb inside the filter, but I can’t find how.

Any tips?

You can get the method type (post or put) from this:

public override void OnActionExecuting(HttpActionContext actionContext)
{
    string methodType = actionContext.Request.Method.Method;
    if (methodType.ToUpper().Equals("POST") 
            || methodType.ToUpper().Equals("PUT"))
    {
         // Your errors
    }
}
