ejabberd - ejabberd MUC-Sub 麻烦

问题描述

我正在运行具有以下 mod_muc 配置的 ejabberd (ver 18.3.0) 服务器：

  mod_muc:
    host: "conference.@HOST@"
    ...
    default_room_options:
      allow_subscription: true
      persistent: true
      mam: true

我正在尝试从各种客户端访问此服务器上的 muc 房间（带有 xmppframework 的 ios，带有 node-xmpp-client 的 js - 手动制作 xmpp 命令）。客户端能够接收消息 - 仅当我在连接后发送存在消息时。

但是，如果不发送出席信息，我不会在客户端收到任何消息（即使订阅成功）。我的理解是接收消息不需要存在消息（对于 mucsub）。

非常感谢任何帮助！

针对 Badlop 的回复的其他详细信息

我将客户端/服务器上的 xml 消息与您发布的消息进行了比较。继续您使用的 user1/user2 示例，我看到 user2 的订阅成功：

<iq xmlns="jabber:client" 
lang="en" 
to="rk3@localhost/abcd" 
from="tr21@conference.localhost" 
type="result" id="D7550060-E2AE-4369-878C-261A02BA48A2">
<subscribe xmlns="urn:xmpp:mucsub:0" nick="rk3n">
<event node="urn:xmpp:mucsub:nodes:messages"/>
<event node="urn:xmpp:mucsub:nodes:presence"/>
</subscribe>
</iq>

此外，来自 user2 的 muc 服务查询结果如下：

<iq xmlns="jabber:client" 
lang="en" 
to="rk3@localhost/abcd" 
from="conference.localhost" type="result" id="B28A237A-5D54-4AE2-821A-195272B05A88">
<subscriptions xmlns="urn:xmpp:mucsub:0">
<subscription jid="tr21@conference.localhost"/>
</subscriptions>
</iq>

但是，当我从 user1 发送群聊消息时：

<message 
from="rk1@localhost" to="tr21@conference.localhost"
type="groupchat">
<body> hi there777hi there778</body>
</message>

User2 仍未收到上述消息。

我在 ejabberd 服务器上打开了日志级别 5，可以看到服务器正在尝试将上述消息发送给 User2 (rk3)。但是，我在服务器上看到的这条消息的最后一条日志如下（我没有看到这条消息的任何“Send XML on stream”日志）。

我可能错过了一些非常基本的东西（wrt user / nick / muc room 等），但不知道是什么。

你能给我你用来创建user1/user2的步骤吗，在服务器上注册他们的昵称等（使用ejabberdctl）？

解决方案

我的理解是接收消息不需要存在消息（对于 mucsub）。

你是对的。有什么奇怪的。所以，我自己尝试过，并为您提供发送和接收的确切节，以便您进行比较，也许您会看到相关的内容。

您还可以尝试使用桌面 Jabber 客户端（如 Gajim、Psi 或 Tkabber）的 XML 控制台手动发送这些节，因此您不必为此测试编写代码。

我像你一样配置模块。然后 user1 加入 room2 （因此它被创建）。user2 订阅了房间：

<iq to='room2@conference.localhost'
    type='set'
    id='E6E10350-76CF-40C6-B91B-1EA08C332FC7'>
  <subscribe xmlns='urn:xmpp:mucsub:0'
             nick='mynick'
             password='roompassword'>
    <event node='urn:xmpp:mucsub:nodes:messages' />
    <event node='urn:xmpp:mucsub:nodes:affiliations' />
    <event node='urn:xmpp:mucsub:nodes:subject' />
    <event node='urn:xmpp:mucsub:nodes:config' />
  </subscribe>
</iq>

<iq xml:lang='es'
    to='user2@localhost/tka1'
    from='room2@conference.localhost'
    type='result'
    id='E6E10350-76CF-40C6-B91B-1EA08C332FC7'>
  <subscribe nick='mynick'
    xmlns='urn:xmpp:mucsub:0'>
    <event node='urn:xmpp:mucsub:nodes:messages'/>
    <event node='urn:xmpp:mucsub:nodes:affiliations'/>
    <event node='urn:xmpp:mucsub:nodes:subject'/>
    <event node='urn:xmpp:mucsub:nodes:config'/>
  </subscribe>
</iq>

紧接着，用户 1 向房间发送一条消息，用户 2 接收它，而没有发送任何出席信息节。

<message to='user2@localhost/tka1'
    from='room2@conference.localhost'>
  <event xmlns='http://jabber.org/protocol/pubsub#event'>
    <items node='urn:xmpp:mucsub:nodes:messages'>
      <item id='1625407893684208871'>
        <message xml:lang='es'
    to='user2@localhost'
    from='room2@conference.localhost/user1'
    type='groupchat'
    id='53:939858'
    xmlns='jabber:client'>
          <archived by='room2@conference.localhost'
    id='1526291787755131'
    xmlns='urn:xmpp:mam:tmp'/>
          <stanza-id by='room2@conference.localhost'
    id='1526291787755131'
    xmlns='urn:xmpp:sid:0'/>
          <body>hi allll</body>
        </message>
      </item>
    </items>
  </event>
</message>

可以肯定的是，user2 向 MUC 服务查询了他的订阅列表，MUC 返回了 room2，另一个他也订阅了：

<iq 
    to='conference.localhost'
    type='get'
    id='E6E10350-76CF-40C6-B91B-1EA08C332FC7'>
  <subscriptions xmlns='urn:xmpp:mucsub:0' />
</iq>

<iq xml:lang='es'
    to='user2@localhost/tka1'
    from='conference.localhost'
    type='result'
    id='E6E10350-76CF-40C6-B91B-1EA08C332FC7'>
  <subscriptions xmlns='urn:xmpp:mucsub:0'>
    <subscription jid='room2@conference.localhost'/>
    <subscription jid='room3@conference.localhost'/>
  </subscriptions>
</iq>
