如何同时获取obj值和键来为POST方法构建数组对象

function buildArrayFromObject(obj) {
  var arr = [];
  for (var key in obj) {
    if (obj.hasOwnProperty(key)) {
      var item = {};
      item.key = key;
      item.value = obj[key];
      arr.push(item);
    }
  }
  return arr;
}

// 示例用法
var obj = { name: 'John', age: 30, city: 'New York' };
var arr = buildArrayFromObject(obj);
console.log(arr);

[
  { key: 'name', value: 'John' },
  { key: 'age', value: 30 },
  { key: 'city', value: 'New York' }
]
