Ramda - 从对象和 return 数组中选取

Question

我有一个 id 数组，我需要用它来从对象中获取扩展信息，所以它看起来像这样：

const arrayOne = [1, 2]

const objectOne =
  {
    "1": {
      "id": 1,
      "reference": "ee",
      "content": {
        "blocks": [
          {
            "type": "plain",
            "data": {
              "text": "Lorem2"
            }
          }
        ]
      }
    },
    "2": {
      "id": 2,
      "reference": "dd",
      "content": {
        "blocks": [
          {
            "type": "plain",
            "data": {
              "text": "Lorem"
            }
          }
        ]
      }
    },
    "3": {
      "id": 3,
      "reference": "dd",
      "content": {
        "blocks": [
          {
            "type": "plain",
            "data": {
              "text": "Lorem"
            }
          }
        ]
      }
    }
  }

然后我使用 Ramda 只从这样的数组中获取 ID：

R.pick(arrayOne)(objectOne)

但后来我得到了对象，我需要的是一个数组。如何转换？

Answer 1

在这种情况下，您可能需要 props：

Acts as multiple prop: array of keys in, array of values out. Preserves order.

props(['1', '2'], {1: "foo", 2: "bar"});
//=>["foo","bar"]
