数据阵列总是处理与Angular.fromjson一起字符串而不是数组

Question

我有问题，我确实将字段表格设置为数组。示例：响应中的字段dfp_interest为[]。因此，我必须将数据设置为阵列吗？我做到了，并在console.log中取得了成功。结果像 -> ["5","6"]，但是当我在angular.fromJson中处理并使用$http发送时，我的params dfp_interest是字符串而不是数组。我错了吗 ？给我解决方案还是我犯了一些错误？

这是我在api

中发送参数的过程

var a = angular.fromJson({
            "data" : "{"username": "newshubid", "data":{"_id": ""+ $scope.id +"","label": ""+ $scope.label +"","active": ""+ $scope.active +"","parent_id": ""+ $scope.parent_id +"","level": ""+ $scope.level +"","meta_title": ""+ $scope.meta_title +"","meta_description": ""+ $scope.meta_description +"", "meta_keyword": ""+ $scope.meta_keyword +"", "dfp_interest": ""+ $scope.tes +""}}"
        });
        var param = $.param(a);
        HttpService("POST", url, param, function(response){
            alert(response.message);
        });

这是我的数据阵列dfp_interest

$scope.tes = [5, 6];
$scope.testarray = $scope.tes.join("");

angular.fromJson接受字符串参数，然后说您的代码应为;

var data = {username: 'newshubid', 
            data: { id: $scope.id, 
                    label: $scope.label, 
                    active: $scope.active,
                    parent_id: $scope.parent_id,
                    level: $scope.level,
                    meta_title: $scope.meta_title,
                    meta_description: $scope.meta_description,
                    meta_keyword: $scope.meta_keyword,
                    dfp_interest: $scope.tes }
           };
    var a = angular.fromJson(JSON.stringify(data));
