Question

我正在尝试在ejabberd中创建一个简单的echo bot。我认为mod_echo工作正常，我相当肯定我有自己的版本在某一点工作（调试已经玩弄了我的头脑）。我收到下面的错误，但我无法弄清楚接下来要做什么来调试它。路由似乎有问题但不太确定原因。有什么提示吗？

似乎在代码示例中（来自我在网上找到的旧样本）https://gist.github.com/stevenlivz/d666200595a23c42b2a662fef87bf281我需要使用＆lt;＆lt;＆＃34; message＆＃34;＆gt;＆gt;在实际匹配的子句中，而我使用的示例代码没有这样做，只使用＆＃34; message＆＃34;等等。另外，还值得注意的是xmlelement现在是xmlel，因此也需要更新子句。 E.g。

route(From, To, {xmlel, <<"message">>, _, _} = Packet) ->
