为使用hexo搭建的博客加入评论系统gitalk

使用hexo结合github搭建自己的个人博客网站,非常方便,而且免费,对于个人来说是一个不错的选择。不过有一个缺点是没有评论系统。需要自己额外引入评论插件。
现在常用的评论插件有三种:
disqus:已经被墙了,暂时不考虑。
gitment:基于github的一个评论系统,但是作者长时间没有维护,需要使用自己的服务器。
gitalk:也是基于github的一个评论系统,目前可以正常使用。
主题不同添加gitalk的方法也略有区别,有的主题本身带有gitalk评论,打开相应的开关就可以。我使用的主题是beantech,本身没有gitalk评论系统。


1.注册


Register a new OAuth application

Application name:随便写。
Homepage URL:网站主页的地址
Application description:随便写
Authorization callback URL:网站主页地址

会生成Client ID与Client Secret。保存好后面会用到。


2.配置gitalk


创建md5.min.js文件

在主题目录source/js中创建md5.min.js文件,内容如下(代码引用自其他文章,链接在文章下方)

admin: 评论管理员,写自己的用户名就可以。
id: 按我写的不需要修改。一定要使用md5编码,不然会因为文章名字过长报错。
其他保持默认即可。

gitalk初始化

将代码放到文章下方后,需要对gitalk初始化,gitalk不能自动初始化,手动初始化后,会在保存评论的仓库新建一个issue。

使用自己的github登录。会在仓库新建一个issue。


这样就完成啦,比较简单。但是需要在每篇文章后面都加入代码,而且需要手动初始化。
可以在主题中加入gitalk,但是因为主题不同加入的方法也不同。
至于初始化,可以写个脚本自动初始化,正在学习中,后期和大家分享。如果大家有更好的方法,欢迎在评论中交流。
