如何在地图中正确使用 async 和 await 关键字

how to properly use the async and await keywords within a map

我有以下代码片段

export const fetchPosts = () => async dispatch => {
  const res = await axios.get(`${url}/posts`, { headers: { ...headers } });
  console.log(res.data);
  let posts = res.data.map(p => (p.comments = fetchComments(p.id)));
  console.log(posts);
  dispatch({ type: FETCH_POSTS, payload: res.data });
};

export const fetchComments = id => async dispatch => {
  console.log(id)
  const res = await axios.get(`${url}/posts/${id}/comments'`, {
    headers: { ...headers }
  });
  console.log("id", id);
  return res.data;
};

当我在控制台记录帖子时,我得到了 2 个函数 returned。我应该如何调用此函数的提取注释以​​ return 我想要的值的正确方法是什么?

添加这个:

const postsResult = await Promise.all(posts)
