在寻找了很多答案后，这是我最好的解决方案:

const renameKey = (oldKey, newKey) => {
  _.reduce(obj, (newObj, value, key) => {
    newObj[oldKey === key ? newKey : key] = value
    return newObj
  }, {})
}

很明显，它没有替换原来的键，而是构造了一个新对象。 问题中的方法有效，但会改变对象的顺序，因为它将新的键-值添加到最后一个对象上。

使用对象解构和展开运算符的变体:

const old_obj = {
    k1: `111`,
    k2: `222`,
    k3: `333`
};    

// destructuring, with renaming. The variable 'rest' will hold those values not assigned to kA, kB, or kC.
const {
    k1: kA, 
    k2: kB, 
    k3: kC,
    ...rest
} = old_obj;
    

// now create a new object, with the renamed properties kA, kB, kC; 
// spread the remaining original properties in the 'rest' variable
const newObj = {kA, kB, kC, ...rest};

对于一个键，这可以很简单:

const { k1: kA, ...rest } = old_obj;
const new_obj = { kA, ...rest }

你也可能喜欢更“传统”的风格:

const { k1, ...rest } = old_obj
const new_obj = { kA: k1, ...rest}

您可以尝试lodash _mapkeys。

Var用户= { 名称:“安德鲁”, id: 25日 报道:假 }; Var重命名= _。mapKeys(用户，函数(值，键){ 返回键+ "_" + user.id; })； console.log(重命名); < script src = " https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.js " > < /脚本>

在您最喜欢的编辑器中尝试一下

const obj = {1: 'a', 2: 'b', 3: 'c'}

const OLD_KEY = 1
const NEW_KEY = 10

const { [OLD_KEY]: replaceByKey, ...rest } = obj
const new_obj = {
  ...rest,
  [NEW_KEY]: replaceByKey
}

const data = res
const lista = []
let newElement: any

if (data && data.length > 0) {

  data.forEach(element => {
      newElement = element

      Object.entries(newElement).map(([key, value]) =>
        Object.assign(newElement, {
          [key.toLowerCase()]: value
        }, delete newElement[key], delete newElement['_id'])
      )
    lista.push(newElement)
  })
}
return lista

如果有人需要重命名属性列表:

function renameKeys(obj, newKeys) {
  const keyValues = Object.keys(obj).map(key => {
    const newKey = newKeys[key] || key;
    return { [newKey]: obj[key] };
  });
  return Object.assign({}, ...keyValues);
}

用法:

const obj = { a: "1", b: "2" };
const newKeys = { a: "A", c: "C" };
const renamedObj = renameKeys(obj, newKeys);
console.log(renamedObj);
// {A:"1", b:"2"}
