Ejabberd 在可用后关闭 BOSH 会话
Ejabberd Closes BOSH session after available presence
我不知道为什么Ejabberd（14.07和14.12）在收到同一会话的"可用"节后关闭BOSH会话。
我正在使用 JsJac 作为 Web 客户端库，会话正在预绑定服务器端，JsJac 在第一页加载时执行"继承"，在重新启动时执行 als。发生这种情况的情况是在成功连接和聊天后，我使用 chrome 开发人员工具禁用网络连接。
Ejabberd 每 15 秒 ping 一次，并在超时时设置为"杀死"。ejabberd.yml 中 BOSH 的Inactivity_timeout设置为 480。
然后，用户可以单击链接以尝试重新连接。这是调用与初始预绑定+客户端继承完全相同的函数。在看似成功的重新连接之后，几秒钟后，这个：
Close session for
anonymous.c6502a950667fc79c3e1534559cc02e0@localhost/7f317c7fcbb9fb1b79c414c2d8afe05c
出现在 ejabberd 日志中，并在聊天中向对方发送不可用的节。
问题：有人知道为什么BOSH会议可能会关闭吗？
这是Ejabberd日志的相关部分

我解决了自己的问题。
-
我已经将mod_ping设置为杀死会话，我相信 BOSH 连接管理器和mod_ping都在杀死会话。我现在将mod_ping更改为"timeout_action"到"无"，并让 BOSH 连接管理器处理断开连接检测。
-
继承连接必须"预加载"BOSH客户端通常从初始bosh响应接收的参数。在我的例子中，依靠遗留代码，当 BOSH 连接管理器响应 2 时，"轮询"参数设置为 5。
JsJac 在 2 秒的"请求"时间段内响应了多达 5 个新请求。
所以我的逻辑是这样的：mod_ping每 15 秒发送一次 ping，BOSH 连接管理器将检查 ping 或任何其他节是否在 4 秒内得到响应。
以下是 Ejabberd BOSH 连接管理器的初始响应：
<body xmlns="http://jabber.org/protocol/httpbind" xmlns:xmpp="urn:xmpp:xbosh" xmlns:stream="http://etherx.jabber.org/streams" sid="42e11a86ecba387ef5f53f5b86d38a8c7dc9ef5a" wait="300" requests="2" inactivity="480" maxpause="120" polling="2" ver="1.8" from="localhost" secure="true" authid="3627063868" xmpp:version="1.0"><stream:features xmlns:stream="http://etherx.jabber.org/streams"><bind xmlns="urn:ietf:params:xml:ns:xmpp-bind"/><session xmlns="urn:ietf:params:xml:ns:xmpp-session"/><sm xmlns="urn:xmpp:sm:2"/><sm xmlns="urn:xmpp:sm:3"/><c xmlns="http://jabber.org/protocol/caps" hash="sha-1" node="http://www.process-one.net/en/ejabberd/" ver="/nWL9StXSXhEsL2wg0+s4xo/UdA="/><register xmlns="http://jabber.org/features/iq-register"/></stream:features></body>
和我的，现在工作，JS代码：
args.polling = 2;
args.inactivity = 4;
args.requests = 2;
args.wait = 300;
self.connection.inherit(args);
附言阅读 http://xmpp.org/extensions/xep-0124.html 后，我将不活动设置为 4 秒，以便更快地检测断开连接。
