从输出中隐藏属性名称

Question

我有一个返回数据的函数。此数据来自具有属性名称的接口。输出具有属性名称。如果可能的话，我想避免这种情况。

我该怎么做呢？

接口：

export interface DataNode {
    id?: number,
    type?: string,
    parentId?: number,
    data?: any,
    children?: DataNode[],
    buildings?: DataNode[],
    areas?: DataNode[],
    rooms?: DataNode[],
    flags?: DataNode[],
    details?: DataNode[]
};

创建输出的代码：

export const fromCity = async (
    city: entities.City,
    depth: "none" | "immediate" | "full"
): Promise<DataNode> => {
    return {
        id: city.id,
        type: "City",
        data: {
            name: city.name,
            title: city.title,
            // created: city.created,
            // updatedAt: city.updatedAt
        },
        buildings: depth !== "none" ?
            await mapChildren((building: entities.Building): Promise<DataNode> => {
                building.city = building.city || Promise.resolve(city);
                return fromBuilding(
                    building,
                    depth === "immediate" ? "none" : depth
                );
            })(await (city.buildings || Promise.resolve([]))) : []
    };
};

我从API得到的实际输出：

            "id": 1,
                "type": "Building",
                "parentId": 1,
                "data": {
                    "name": "data-center",
                    "title": "Data Center",
                    "subtitle": "Secure Data Center and Cloud NOC",
                    "x": "11.30",
                    "y": "41.50"

我想从API中得到什么：

            "id": 1,
                "type": "Building",
                "parentId": 1,
                {
                    "name": "data-center",
                    "title": "Data Center",
                    "subtitle": "Secure Data Center and Cloud NOC",
                    "x": "11.30",
                    "y": "41.50"

注意"data":的消失。这就是我想隐藏的。

有没有一种简单的方法来告诉你“不返回这个属性名，只返回它的值”？

Answer 1

对象的键必须是字符串。因此，最接近所需输出的方法是将"data"键命名为空字符串""

Answer 2

Javascript不允许这样做。如果没有键来访问它，就不能有一个值，否则数据将无法通过对象访问。你能做的就是让它输出一个数组：

[
  {
    "id": 1,
    "type": "Building"
    "parentId": 1
  },
  {
    "name": "data-center",
    "title": "Data Center",
    "subtitle": "Secure Data Center and Cloud NOC",
    "x": "11.30",
    "y": "41.50",
  }
]

然后，您可以从访问数据

JSON.parse(JSONresponse[1]);
