数组 – 当forEach循环全部完成时迭代数组

我试图迭代我在angular.forEach()内的多个http调用构造的数组

功能

$scope.ticket_stats = function(){
    //cleaning variables
    $scope.data_set = [];
    $scope.closed_tickets = [];

    //fetching time stamps (epoch)
    $scope.time_frame = time_period.days(7);

              //calling data using time stamps
              angular.forEach($scope.time_frame,function(item) {
                  //debug
                  console.log(item);

                  var promise = tickets.status("closed",item);

                  promise.success(function(data){
                      console.log(data);
                      $scope.closed_tickets.push(data[0].datapoints[0][0]); // returns a numerical value
                  });

              });
              //SEE messaGE BELOW
              $scope.data_set.push($scope.closed_tickets);

}

$scope.data_set.push()的最后一行正在工作,但一旦调用返回数据就会随着时间的推移自行递增.我想在for Each循环中的所有内容都完成之后执行此行.我需要迭代$scope.closed_tickets数组,然后在其中播放(添加)数据并构建第二个数组.

以下是此功能中使用的服务：

// CALL TICKETS STATS
app.service('tickets',function($http){

    this.status = function(status,datE){
        var one_snap = date - 100;
        var url = "/url/render?format=json&target=sum(stats.tickets."+status+")&from="+one_snap+"&until="+date+"";
        return $http.get(url);
    };            
});

// TIME STAMPS MATHS
app.service('time_period',function(){
    var currentDate = parseInt((new DatE).getTime()/1000);

    this.days = function(number){
        var pending = [];
        for (var i = number; i > 0; i--) {
            pending.push(currentDate - (87677*i));
        }
        return pending;
    }; 
});

我搜索信息并发现有关$q.all()服务的信息,但没有设法以我想要的方式完成这项工作.

任何建议都会受到欢迎！
谢谢！

$scope.ticket_stats = function() {
    // list of all promises
    var promises = [];

    //cleaning variables
    $scope.data_set = [];
    $scope.closed_tickets = [];

    //fetching time stamps (epoch)
    $scope.time_frame = time_period.days(7);

    //calling data using time stamps
    angular.forEach($scope.time_frame,function(item) {
        // create a $q deferred promise
        var deferred = $q.defer();
        //debug
        console.log(item);

        tickets.status("closed",item).success(function(data) {
            console.log(data);
            $scope.closed_tickets.push(data[0].datapoints[0][0]);

            // promise successfully resolved
            deferred.resolve(data);
        });

        // add to the list of promises
        promises.push(deferred.promisE);
    });

    // execute all the promises and do something with the results
    $q.all(promises).then(
        // success
        // results: an array of data objects from each deferred.resolve(data) call
        function(results) {
            $scope.data_set.push($scope.closed_tickets);
        },// error
        function(responsE) {
        }
    );
}
