I am using eJabberd server (MAM enabled) with client library Strophe.js. Client app is storing fixed amount of the messages in local storage.
All the messages, that I receive from the server include elements <archived/>
and <stanza-id/>
, which provide server-side generated IDs:
<message
xmlns="jabber:client" to="[email protected]/8667085700924567016834" from="[email protected]">
<result
xmlns="urn:xmpp:mam:2" id="1520510373346685">
<forwarded
xmlns="urn:xmpp:forward:0">
<message
xmlns="jabber:client" xml:lang="en" to="[email protected]" from="[email protected]/60965696931000870402419" type="chat">
<archived
xmlns="urn:xmpp:mam:tmp" by="[email protected]" id="1520510373346685"/>
<stanza-id
xmlns="urn:xmpp:sid:0" by="[email protected]" id="1520510373346685"/>
<body>asdf</body>
</message>
<delay
xmlns="urn:xmpp:delay" from="example.net" stamp="2018-03-08T11:59:33.346685Z"/>
</forwarded>
</result>
</message>
I use these IDs to get fixed amount of messages on each MAM call (using RSM paging - before/after/max attributes). For example:
params = {
"before": "1520510373346685",
"max": 10,
onMessage: <some handler>,
onComplete: <some handler>,
}
this.connection.mam.query(Strophe.getBareJidFromJid(this.myJid), params);
This gets me 10 messages before the message with stanza-id 1520510373346685
.
However, the messages I send inherently do not have this ID, until I send them and retrieve from MAM.
I did not find any examples on getting the currently sent message ID from the server, and the Strophe does not provide any callbacks after the message was sent from the client and received by the server.
So, the question - is there any way to get the server-generated message ID (stanza-id/archived) for the currently sent message?
Maybe my own approach is wrong - should I generate my own IDs and add it to each message from the client?
