为你的博客添加版权

自己做自建博客也有一段时间了，有转载别人的博客，也有自己动手写博客。在没做独立博客之前，对版权意识并不是那么重视，也没了解过自己文章的收录情况。最近为了提高网站的收录量，开始将一些自己原创的博客放到oschina 等博客平台上去。但是发现自己的文章很快就被收录了，然后被别的权重较高的网站转载。结果就是自己辛辛苦苦写的文章为他人做了嫁衣，还没有自己的署名新。于是开始研究为自己文章加上版权信息。人家的hexo博客主题都要自带的版权申明，奈何我的没有，于是只能自己写咯，谁让我要选择这个博客主题呢，谁让我要自己搞独立博客呢。因为之前有过自己在博客主题里面添加信息的经历，所以此次添加就比较简单了。因为我的博客主题页面用的是Ejs模板写的，所以需要先写一个Ejs模板，模板主要写的就是版权的布局内容。 copyright.ejs <% if (!index || !post.excerpt) { %> <div class="post-copyright"> <div class="author"> <b>本文作者： </b> post.author </div> <div class="link"> <b>本文链接： </b> <a href=" <%= post.permalink %>" target="_blank"> <%= post.permalink %> </a> <
