Typecho升级之后，提示：Call to undefined method Typecho\Router::getPathInfo()

今天把Typecho的版本升级到了1.2.1，然后出现一系列错误：

经过排查，这个错误是由CateFilter插件导致的，需要修改插件的实现部分，改为下面即可：

    public static function filter($obj, $select){
        $path_info = strtolower($_SERVER['REQUEST_URI']);  // 使用 $_SERVER['REQUEST_URI'] 获取路径信息

        if('/feed' == $path_info || '/feed/' == $path_info) return $select;
        $CateIds = Typecho_Widget::widget('Widget_Options')->plugin('CateFilter')->CateId;
        if(!$CateIds) return $select;       //没有写入值，则直接返回
        $select = $select->select('table.contents.cid', 'table.contents.title', 'table.contents.slug', 'table.contents.created', 'table.contents.authorId','table.contents.modified', 'table.contents.type', 'table.contents.status', 'table.contents.text', 'table.contents.commentsNum', 'table.contents.order','table.contents.template', 'table.contents.password', 'table.contents.allowComment', 'table.contents.allowPing', 'table.contents.allowFeed','table.contents.parent')->join('table.relationships','table.relationships.cid = table.contents.cid','right')->join('table.metas','table.relationships.mid = table.metas.mid','right')->where('table.metas.type=?','category');
        $CateIds = explode(',', $CateIds);
        $CateIds = array_unique($CateIds);  //去除重复值
        foreach ($CateIds as $k => $v) {
            $select = $select->where('table.relationships.mid != '.intval($v))->group('cid');//确保每个值都是数字；排除重复文章
        } 
        return $select;
    }
