在 res.json 响应中循环一个 var 键

Question

所以这是我的代码部分：

var roomid= roomIds[i] 
const Availabilitydata = await AvailResponse.json();
    availableroomsArray.push(Availabilitydata);
    
        app.get("/api/availability", (req, res) => {
            res.json({ indicateur: availableroomsArray});});
    }

所以变量 indicateur 在数组中循环 3 个房间 ID 因此，当您访问 /api/availability 时，它将以这种方式打印 2022-03-20 中 3 个房间的可用性

{"indicateur":[{"20220320":{"i":1,"p1":"74.00","p2":"78.00","p3":"70.3000","p4":"122.4600"},"20220320"{"i":0,"p1":"74.00","p2":"77.00","p3":"70.3000","p4":"120.8900"},"20220320":{"i":0,"p1":"65.00","p2":"68.00","p3":"61.7500","p4":"106.7600"}}]}

它运行良好。

我想要实现的是像这样在可用性前面显示每个房间的 roomId :

{"1212":[{"20220320":{"i":1,"p1":"74.00","p2":"78.00","p3":"70.3000","p4":"122.4600"}]},
{"1213":[{"20220320"{"i":0,"p1":"74.00","p2":"77.00","p3":"70.3000","p4":"120.8900"}]},
{"1214":[{""20220320":{"i":0,"p1":"65.00","p2":"68.00","p3":"61.7500","p4":"106.7600"}}]}

我试图用 roomid 替换 res.json({ indicateur: availableroomsArray});}); 中的 indicateur 但它会按原样打印

解决方案是创建一个对象var obj = {};来存储（键，值）对

   obj[roomIds[i]] = Availabilitydata; // key,value pairs object
    availableroomsArray.push(obj);

        app.get("/api/availability", (req, res) => {
            res.json({ availability : availableroomsArray});});
    }

在 res.json 响应中循环一个 var 键
