在我看来，您似乎只需要解构iddoFeed对象即可。您的问题尚不清楚，但我认为这是您要尝试做的事情。

let feeds = []

    snapshot.forEach((childItem) => {
        feeds.push({
            key: childItem.key,
            id: childItem.val().iddoFeed.id_user,
            id_user: childItem.val().iddoFeed.id_user,
            url: childItem.val().iddoFeed.url,
            date_posted: childItem.val().iddoFeed.date_posted,
            name: childItem.val().iddoFeed.name,
            avatar:childItem.val().iddoFeed.avatar,
            like_count: childItem.val().iddoFeed.like_count,
            is_liked: childItem.val().iddoFeed.is_liked,

        })
    })
