我正在尝试重构我获取的 JSON 数据。我的 JSON 响应示例如下:

            "contentType": "image/jpeg"
          }
        }
      }
    ]
  }
};

我想从includes > Asset中获取fields键和属性，并将它们放入正确的item > fields > picture中具有匹配的 ASSETID。然后包含将从整个事物中删除，因为不再需要它。

这就是我想要的最终结果:

我目前拥有的是一个函数，它会迭代 items 中的每个项目，并尝试查看 Assets 数组是否包含来自的 ASSETID该项目。

const items = data.items.slice(0);
const assets = data.includes.Asset.slice(0);

items.forEach(item => {
  if (item.fields.picture !== undefined) {
    const {
      id
    } = item.fields.picture.sys;
    const mappedAssets = assets.map(asset => asset.sys.id);

    if (mappedAssets.includes(id)) {
      console.log('This id matched:', id)
    }
  }
})

const data = {

const items = data.items.slice(0);
const assets = data.includes.Asset.slice(0);

items.forEach(item => {
  if (item.fields.picture !== undefined) {
    const {
      id
    } = item.fields.picture.sys;
    const mappedAssets = assets.map(asset => asset.sys.id);

    if (mappedAssets.includes(id)) {
      console.log('This id matched:', id)
    }
  }
})

我不知道如何按照我想要的方式传播属性。我的方向是正确的还是我的想法有问题？

最终的解决方案是:

    data.items.forEach(item => {
      if (item.fields.picture !== undefined) {
        const { id } = item.fields.picture.sys;
        const foundAssets = data.includes.Asset.find(asset => asset.sys.id === id);
        item.fields.picture = { ...item.fields.picture, fields: {...foundAssets.fields} };
      }
    });
    delete data.includes;

最佳答案

我想可以简单地使用forEach，进行匹配，传播需要的内容并删除不需要的内容。像这样的事情
