如何把历史上的post迁移到本站

THIS POST IS OUTDATED, REFER TO THE LATEST VERSION

1. 添加 front matter。
2. 把源 post 复制到/_posts/，重命名为YYYY-MM-DD-${title}.md的格式。 I may leave title as is knowing that chineses characters are preserved in browser’s address bar and white spaces will be automatically replaced with dashes.
3. 如果有，把*.assets文件夹移到/assets/blog-images。
4. 在源 post 中给所有图片链接 prefix /assets/blog-images。
