如何扩展或覆盖BeginForm以包含AntiForgeryToken字段

@using (Html.BeginForm("ActionName", "ControllerName"))
{
    @Html.AntiForgeryToken()
    // 其他表单元素
}

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult ActionName(ModelName model)
{
    // 处理表单提交
}

$.ajax({
    url: "/ControllerName/ActionName",
    type: "POST",
    data: {
        // 表单数据
    },
    headers: {
        "RequestVerificationToken": '@Html.AntiForgeryTokenValue()'
    },
    success: function (result) {
        // 处理成功
    },
    error: function (result) {
        // 处理错误
    }
});

public class ValidateAntiForgeryTokenAttribute : FilterAttribute, IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationContext filterContext)
    {
        if (filterContext == null)
        {
            throw new ArgumentNullException("filterContext");
        }

        var httpContext = filterContext.HttpContext;
        var request = httpContext.Request;

        if (request.HttpMethod == WebRequestMethods.Http.Post)
        {
            var antiForgeryCookie = httpContext.Request.Cookies[AntiForgeryConfig.CookieName];
            var antiForgeryCookieValue = antiForgeryCookie != null ? antiForgeryCookie.Value : null;

            try
            {
                AntiForgery.Validate(antiForgeryCookieValue, request.Headers["RequestVerificationToken"]);
            }
            catch (HttpAntiForgeryException e)
            {
                throw new HttpAntiForgeryException("AntiForgeryToken验证失败", e);
            }
        }
    }
}

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new ValidateAntiForgeryTokenAttribute());
}
