如何将数组转换为 MongoDB 中的对象？

例如，我想转换这个文档：

{
"_id" : NumberLong(279),
"userAddressList" : [ 
    {
        "street" : "Street",
        "house" : "House",
        "building" : "Building",
        "flat" : NumberLong(0),
        "entrance" : NumberLong(0),
        "floor" : NumberLong(0),
        "intercom" : "Intercome"
    }
        ],
}

对此：

{
"_id" : NumberLong(279),
"userAddressList" :
    {
        "street" : "Street",
        "house" : "House",
        "building" : "Building",
        "flat" : NumberLong(0),
        "entrance" : NumberLong(0),
        "floor" : NumberLong(0),
        "intercom" : "Intercome"
    },
}

所以我需要转换""userAddressList" : [{..}]"为""userAddressList" : {..}".

当对象的类型发生变化时，我陷入了困境。

我该如何转换：

{ 
"_id" : NumberLong(257),
"address" : "street  Street, house 50, appartment 508, floor 5"
}

对此：

{ 
"_id" : NumberLong(257),
 "userAddressList" : [{
        "street" : "Street",
        "house" : "50",
        "building" : "",
        "appartment " : NumberLong(508),
        "entrance" : NumberLong(0),
        "floor" : NumberLong(5),
        "intercom" : ""
    }]
}

使用 mongo 外壳？

我需要转换大约 350 个条目，希望可以通过脚本来完成。
