Answer 1

1.Define Function to get Token from server

@function
{

        public string TokenHeaderValue()
        {
            string cookieToken, formToken;
            AntiForgery.GetTokens(null, out cookieToken, out formToken);
            return cookieToken + ":" + formToken;                
        }
}

2.Get token and set header before send to server

var token = '@TokenHeaderValue()';    

       $http({
           method: "POST",
           url: './MainBackend/MessageDelete',
           data: dataSend,
           headers: {
               'RequestVerificationToken': token
           }
       }).success(function (data) {
           alert(data)
       });

3. Onserver Validation on HttpRequestBase on method you handle Post/get

        string cookieToken = "";
        string formToken = "";
        string[] tokens = Request.Headers["RequestVerificationToken"].Split(':');
            if (tokens.Length == 2)
            {
                cookieToken = tokens[0].Trim();
                formToken = tokens[1].Trim();
            }
        AntiForgery.Validate(cookieToken, formToken);
