用angular.js和websocket通过MtGox的Streaming API获取比特币实时行情

代码如下：

 var w = new window.WebSocket("wss://websocket.mtgox.com/mtgox"); w.onmessage = function(d) {     var data = angular.fromJson(d.data);     if (data.channel_name === 'trade.BTC' && data.trade.price_currency === 'USD') {         $scope.$apply(function() {                 $scope.price = data.trade.price;                 });     } };
