Typecho 使用 CommentToDingtalk (评论推送至钉钉)插件遇到的问题
CommentToDingtalk 项目地址：https://github.com/MoLeft/CommentToDingtalk
运行报以下错误
Using $this when not in object context
Error: Using $this when not in object context in //nowtime.cc/usr/plugins/CommentToDingtalk/Plugin.php:123

#6 {main}原因
在静态方法中调用非静态方法，导致其报错
解决方法
将 静态方法 中调用 非静态方法 $this-> 改成 (new self())-> 即可
以下是修改后的 Plugin.php，你可以直接复制以下代码进行替换：
<?php
if (!defined('__TYPECHO_ROOT_DIR__')) {
exit;
}
