我已经设置了 openfire 服务器，我的 android 客户端可以很好地使用它，除了我无法发布头像，问题是服务器只是忽略了发布头像 iq 数据包，没有错误，日志文件中没有任何内容。我正在使用标准的 XMPP pep avatar stanza，请支持

谢谢大家的回复，我发现问题出在 openfire server 3.10，它不能很好地解析标准 XEP 0084 节，事实上我发现日志和服务器崩溃了，所以我将 IQ 修改为，例如这应该是标准发布头像的智商

<iq type='set' from='juliet@capulet.lit/chamber' id='publish1'>
  <pubsub xmlns='http://jabber.org/protocol/pubsub'>
    <publish node='urn:xmpp:avatar:data'>
      <item id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'>
        <data xmlns='urn:xmpp:avatar:data'>
          qANQR1DBwU4DX7jmYZnncm...
        </data>
      </item>
    </publish>
  </pubsub>
</iq>

但是正如您所看到的，标准 IQ 中没有“to”地址，openfire 服务器会在 DB 中创建 pubsub 节点并崩溃，并且不会回复要求用户现在发布元数据的结果，所以我必须做的是发送此数据包，然后是标准元数据数据包，然后再次发送带有“to”地址的元数据数据包，该地址将由服务器回复，结果元数据通知成功作为标准元数据首次发送到服务器，

<iq type='set' from='juliet@capulet.lit/chamber' id='publish2'>
      <pubsub xmlns='http://jabber.org/protocol/pubsub'>
        <publish node='urn:xmpp:avatar:metadata'>
          <item id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'>
            <metadata xmlns='urn:xmpp:avatar:metadata'>
              <info bytes='12345'
                    id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'
                    height='64'
                    type='image/png'
                    width='64'/>
            </metadata>
          </item>
        </publish>
      </pubsub>
    </iq>

然后再次像这样添加“到”地址

<iq type='set' from='juliet@capulet.lit/chamber' to="mydomain.com" id='publish2'>
  <pubsub xmlns='http://jabber.org/protocol/pubsub'>
    <publish node='urn:xmpp:avatar:metadata'>
      <item id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'>
        <metadata xmlns='urn:xmpp:avatar:metadata'>
          <info bytes='12345'
                id='111f4b3c50d7b0df729d299bc6f8e9ef9066971f'
                height='64'
                type='image/png'
                width='64'/>
        </metadata>
      </item>
    </publish>
  </pubsub>
</iq>

以上述方式头像发布正在工作，我也成功向其他用户发出通知

这是服务器崩溃日志以防万一
