gatsby-config.js配置为从./content目录中获取所有降价文件。
ServicePostBlogPost模板从./src/content/services目录
中获取数据./src/content/blog。
gatsby-node.js./src/content/根据templateKeymarkdown 文件的 frontmatter 中的集合对数据进行排序，并将其传递给createPage生成页面/services/service-name和/blog/blog-article-nameURL。
我遇到的问题是所有/services/service-name和/blog/blog-article-name页面都是使用来自./services/和./blog/目录的第一篇文章的数据生成的。
