Как динамически изменить ключ JSON (включая его дочерние ключи) в Javascript?

Question

Я получаю JSON с конечной точки и хотел бы вставить его в базу данных mongoDB.Проблема в том, что некоторые ключи, которые приходят из JSON, имеют "."внутри него и mongoDB выдает ошибку, когда он предполагает вставить ключ такого типа, например:

object: {
"DR.No": 1
}

Это фактическая конечная точка, которую я получаю: https://api.opensea.io/api/v1/asset_contracts/ Это массив объектову некоторых из них есть объект «черты», который иногда имеет такие значения ключа (Ctrl + F и поиск «DR.», чтобы понять, что я имею в виду).

Когда я удалил этот раздел, все работалоЧто ж.

app.post("/something", (req, res, next) => {
   fetch("https://api.opensea.io/api/v1/asset_contracts/")
  .then(r => r.json())
  .then(data => {
    for (let i = 0; i < data.length; i++) {
      delete  data[i].traits; //works when deleted, I need it though
      ...

Мне нужен раздел черт.Я хотел бы заменить все точки запятыми.Поэтому мне нужно динамически менять имя ключа и его дочерних ключей.

Подобные вопросы сосредоточены больше на том, как включить.участвовать в mongoDB, чем динамически менять ключ (это решение, которое я хочу)

Answer 1

Один из возможных способов сделать это - переписать ключи в новый объект, например, так:

let obj = {};
let o = { "DR.No":1, "foo": 2 };
let keys = Object.keys(o);
for(let i = 0;i < keys.length;i++) {  
    let key = keys[i];
    obj[key.replace(".",",")] = o[key] 
}
JSON.stringify(obj,null,2)

"{
  "DR,No": 1,
  "foo": 2
}"

Или, если точек много:

let obj = {};
let o = { "DR.No.Blah.Dots.ToMany":1, "Weird.Dots.In.Keys": 2 };
let keys = Object.keys(o);
for(let i = 0;i < keys.length;i++) {  
    let key = keys[i];
    let originalKey = key;
    key = key.split(".").join(",");
    obj[key] = o[originalKey] 
}
JSON.stringify(obj,null,2)
"{
  "DR,No,Blah,Dots,ToMany": 1,
  "Weird,Dots,In,Keys": 2
}"

Если вы хотитеключи, которые не имеют пунктуации в них, избавляют от запятых ....

.... В ответ на ваш комментарий здесь один из возможных способов сделать это.Взяв образец из данных JSON в вашем вопросе:

Answer 2

возможно

data[i].traits = Object.entries(data[i].traits).reduce((memo, [key, value]) => {
  memo[key.replace(/./g, ',')] = value;
  return memo;
}, {});
