angularjs将java返回的json变换成js所能识别的json

$http({
   method: "GET",//请求方式
   url: "http://localHost:8080/jeewx/activeController.do?cancelTags&userId="+userId+"&relId="+activeId+"&tagsType=2"
}).success(function (result) {
   //if(status==200){
   //如果请求成功就-1
   console.log(angular.fromJson(result));
   if(angular.fromJson(result).msg=="success"){
   }
   //}
}).error(function (data,status,header,config){
   console.log(1);
});
