从SignalR Hub类中重定向用户

Question

我有一个按钮,用户可以点击以对某些内容出价.每次出价都会向每个其他客户广播最新出价.这就是我使用SignalR的原因.

现在,用户需要有积极的积分,如果他没有积分我想在某个地方重定向他.

更明显的方法让我失望,所以任何建议都是受欢迎的.

//Does the user have credits to spend?
if (user.LanceCreditBalance >= 1)
{
    //populate the "ar" object and send it out to everybody.
    var result = Json.Encode(ar);
    Clients.addMessage(result);
}
else
{
    //And this isn't working as expected. Doesn't redirect
    //And causes a 302 error when viewing the Firebug console in Firefox.
    HttpContext.Current.Response.Redirect(@"http://www.google.com");
}

上面的代码都在Chat类中,它继承自SignalR.Hub类.

服务器:

if(user.LanceCreditBalance >= 1)
{
    var result = Json.Encode(ar);
    // send Message to all clients
    Clients.addMessage(result);
}
else
{
    // Invoke a js-Function only on the current client
    Caller.redirectMe("http://www.google.com");
}

客户:

$(function () {
    var chat = $.connection.chat;

    chat.addMessage = function(message) {
        // do something
    };

    // function the server can invoke
    chat.redirectMe = function(target) {
        window.location = target;
    };

    $.connection.hub.start();
});
