我有一个将一个JSON设置到Cloud Firestore数据库的函数：

app.post('/api/add/collection/:collection_id/permission/:permission_id',(req,res) => {
(async () => {
    try {
        await db.collection(req.params.collection_id)
            .doc(req.params.permission_id)
            .set({
                [req.body.id]: {
                    name: req.body.name,email: req.body.email,phone_number: req.body.phone_number
                }
            },{ merge: true}
            );

        return res.status(200).send('OK');
    } catch (error) {
        console.log(error);
        return res.status(500).send('ERROR' + error);
    }
})();
});

要调用此函数，我将JSON正文传递给POST请求：

https://.../app/api/add/collection/USER_ID/permission/PERMISSION_id

{
    "id": 45,"name": "Stack","email": "stack@overflow.com","phone_number": "+48 111 222 333"
}

一切正常，该请求将此JSON设置为一个映射，以id为键，值分别为name，email和phone_number。但是我想在一个请求中传递几个JSON，以将多个地图对象添加到我的NoSQL文档中，例如：

[
    {
        "id": 45,"phone_number": "+48 111 222 333"
    },{
        "id": 46,"name": "Stack2","email": "stack2@overflow.com","phone_number": "+48 222 222 333"
    },{
        "id": 47,"name": "Stack3","email": "stack3@overflow.com","phone_number": "+48 333 222 333"
    }
]

如何修改我的firebase函数以实现此目的？
