如果刷新页面，则重置XMPP连接 [英] reset the XMPP connection if the page gets refreshed
问题描述
我试图在我的ejabberd服务器上使用javascript与XMPP建立strophe连接，我能够在页面加载时建立连接，并且在单击断开连接按钮时能够断开连接。
I am trying to create a strophe connection with XMPP using javascript with my ejabberd server , i am able to make a connection when the page loads and able to disconnect when the disconnect button is clicked.
现在的问题是，连接仍然有效，如果用户不小心刷新了页面，则我的JavaScript试图再次建立连接，并对此做出响应。 （仅是因为以前的连接可能仍然存在）
now the problem is , the connection is alive and if a user accidently refresh the page , then my javascript is trying to make the connect again , and in response to that i am getting. (its just because the previous connection might be still alive )
<body xmlns='http://jabber.org/protocol/httpbind'>
<failure xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
<not-authorized/>
</failure>
</body>
过一会儿，如果我再次刷新页面，则连接将成功建立，那么我怎么能如果页面被意外刷新，请重置连接，以便用户获得无缝连接。
and after a while if i refresh the page again then connection will get established successfully, so how can i reset the connection in case if the page is accidently refreshed so that a user get a seamless connection.
推荐答案
该连接在整个页面刷新过程中都有效，请保持 jid ， sid 和 rid 变量，以及您需要的任何其他状态，例如sessionStorage。然后，您可以使用 attach（） 恢复XMPP会话。
If you want to have the connection survive across a page refresh, keep the jid, sid and rid variables, along with any other state you need, in something like sessionStorage. You can then use attach() to resume the XMPP session.
