我在20.07版本中安装并使用了mod_offline_http_post模块，能够为单个用户获取推送通知。但是这个模块不支持MUC房间。我想为订阅了MUC房间并且目前处于离线状态的用户获得推送通知。我发现mod_offline_post模块可以做到这一点。但我无法配置[mod_offline_post]与ejabberd 20.07版本。对于编译和安装，我遵循了以下说明https://docs.ejabberd.im/developer/extending-ejabberd/modules/.
完成此操作后，当我尝试在ejabberd.yml中配置mod_offline_post时，它会给我一个错误mod_offline_post不是ejabberd模块。
好吧，该模块已有两年的历史，并且不符合ejabberd模块API的最新要求，所以它不是ejabber模块。
我已经更新了它的源代码，以便使用最新的ejabberd进行正确编译。我还没有检查它是否真的有效。
这些步骤允许下载、修复和安装模块：
mkdir -p $HOME/.ejabberd-modules/sources/
cd $HOME/.ejabberd-modules/sources/
git clone https://github.com/k9428/mod_offline_post.git
cd mod_offline_post
然后在这里放一个名为update.patch的文件，其中包含以下内容：
