Typecho网站了的服务器环境 Debian 12 + Nginx 1.28 + PHP8.2 + Mysql 8.4 + Typecho 1.3.0
网站主题使用Typecho-Butterfly
网站开启了以下插件 AutoSaveImage、Keywords、Paste Image、ShortLinks
其中缩短链接插件关的作用：可以将外链转换成内链，减少链接损失；另外也可以直到缩短链接的作用；
问题说明：
打开网站首页时，页面上有以下错误提示信息：
Deprecated: unserialize(): Passing null to parameter #1 ($data) of type string is deprecated in /www/wwwroot/xqbn.com/usr/plugins/ShortLinks/Plugin.php on line 181其中缩短链接插件的代码如下：

}报错问题分析
这个警告的出现，是因为在 PHP 8.1+ 版本中，unserialize() 函数要求传入的参数必须是字符串，而 $widget->fields 在某些情况下可能为 null，从而触发了弃用通知。
🔧 修复 ShortLinks 插件警告
要修复第181行的警告，需要修改 /www/wwwroot/xqbn.com/usr/plugins/ShortLinks/Plugin.php 文件。
定位代码：找到
replace函数中的第181行，原代码如下：$fields = unserialize($widget->fields);修改代码：将其修改为以下内容，增加对
$widget->fields的判断：// 修复：在反序列化前检查字段是否存在且为字符串 $fields = (!empty($widget->fields) && is_string($widget->fields)) ? unserialize($widget->fields) : false;修改后的完整上下文（第180-184行） 应类似于：
if ($pluginOption->convert == 1) { $fields = (!empty($widget->fields) && is_string($widget->fields)) ? unserialize($widget->fields) : false; if (is_array($fields) && array_key_exists("noshort", $fields)) { // 部分文章不转换 return $text; }
修改完成后，Typecho缩短链接插件 ShortLinks 完整的代码如下：
