Controller

$scope.downloadExport = function (id,filename,frmdata) {
         frmdata = {};
        var data = tdioServices.downloadexport(id,filename,frmdata);
         data.success(function(success) {
                var blob = new Blob([success], { type:"arraybuffer" });           
                var downloadLink = angular.element('');
                downloadLink.attr('href',window.URL.createObjectURL(blob));
                downloadLink.attr('download', filename);
                downloadLink[0].click();
                $COMMON_ACCEPT = "Download Successfully";
                $COMMON_ACCEPT_TEXT = "Success";
                toastr.success($COMMON_ACCEPT, $COMMON_ACCEPT_TEXT);

        });
    };

Services

 this.downloadexport = function(id,filename,frmdata){
       var request = $http({method:'get', url:APP_URL+'/exports/'+id+'/download/'+filename, data:frmdata,responseType:'arraybuffer'});
       return request;        
    }
