如何解决尝试使用RSS Feed从博客恢复帖子到我的Gatsby网站，有人知道什么是好的插件以及如何解析查询？
GatsbyJS的新功能，我需要帮助来检查RSS Feed，但我迷路了！
我想将另一个博客的RSS Feed检查到我的gatsby站点，我想将该博客的帖子找回我的gatsby站点。
有人可以告诉我是否需要安装： “ gatsby源RSS提要”（我认为），“ gatsby源RSS”或“ gatsby RSS提要”（我认为不是，是将他的gatsby帖子推送到另一个博客的，我需要相反的意思）？
如果有人还可以向我展示如何声明RSS的查询？在女巫文件夹中？

还是在我模板的文件夹中？
非常感谢。
解决方法
此插件 gatsby-plugin-parse-rss 将解析来自 RSS 提要页面的信息并自动创建查询。
在您的 gatsby-config.js
plugins: [
{
resolve: "gatsby-plugin-parse-rss",options: {
rss: [
{
urlToFetch:
"https://lydra.fr/tag/froggit/feed/rss.xml",selectors: ["media:title"],name: "lydraRSS",},],];
使用 gatsby 的 useStaticQuery 检索数据
{
allLydraRss {
nodes {
media_title
}
}
}
