404 (Invalid SID) in Strophe when using attach ()
I've searched google and some similar questions about Stack Overflow. But I am not getting any solution.
Basically, I want to keep the connection across web pages in my application. I use cookies for this. I store the SID and RID in cookies and use them to reconnect the session.
Below is my code.
this.openConnection = function(){
if (chatObj.connection != null) return;
var jid = chatObj.userName + '@' + chatObj.openfireDomainURL; // Bare JID
var sid = Cookies.get(chatObj.userName + '_sid'); // Session Identifier
var rid = Cookies.get(chatObj.userName + '_rid'); // Request Identifier
var connection = new Strophe.Connection(chatObj.xmppHttpBindURL);
chatObj.connection = connection;
if(chatObj.isEmpty(sid) && chatObj.isEmpty(rid)){
connection.connect(jid, chatObj.password, chatObj.onConnection);
} else {
// parseInt(rid,10) + 1
var rid = parseInt(rid) + parseInt(1);
connection.attach(jid, sid, rid, chatObj.onConnection);
}
};
this.onConnection = function(status) {
if (status === Strophe.Status.CONNECTED) {
chatObj.log("CONNECTED ");
//Cookies.set(chatObj.userName + '_sid', chatObj.connection.sid);
//Cookies.set(chatObj.userName + '_rid', chatObj.connection.rid);
jQuery(document).trigger('connected');
} else if (status === Strophe.Status.DISCONNECTED) {
jQuery(document).trigger('disconnected');
chatObj.log("DISCONNECTED ");
} else if (status === Strophe.Status.CONNFAIL) {
chatObj.log("CONNFAIL ");
} else if (status === Strophe.Status.AUTHENTICATING) {
chatObj.log("AUTHENTICATING ");
} else if (status === Strophe.Status.AUTHFAIL) {
chatObj.log("AUTHFAIL ");
} else if (status === Strophe.Status.ERROR) {
chatObj.log("ERROR ");
} else if (status === Strophe.Status.ATTACHED){
chatObj.log("ATTACHED ");
jQuery(document).trigger('connected');
} else if (status === Strophe.Status.CONNFAIL){
chatObj.log("CONNFAIL ");
}
};
$(window).unload(function() {
console.log("widows unload ");
if( chatObj.connection != null ){
console.log("set cookies ");
Cookies.set(chatObj.userName + '_sid', chatObj.connection.sid);
Cookies.set(chatObj.userName + '_rid', chatObj.connection.rid);
} else {
// Cookies.remove(chatObj.userName + '_sid');
// Cookies.remove(chatObj.userName + '_rid');
}
});
404 Invalid SID value in Strophe when using attach ()
I tried to use Windows unload but it didn't work. I still get the same error.

Instead of using a method, attach()
there is also a function restore
combined with an option keepalive
:
var connection = new Strophe.Connection(chatObj.xmppHttpBindURL, {'keepalive': true});
...
try {
connection.restore(jid, onConnect);
} catch(e) {
if (e.name !== "StropheSessionError") { throw(e); }
}
See: http://strophe.im/strophejs/doc/1.2.14/files/strophe-js.html#Strophe.Connection.restore
and
https://github.com/strophe/strophejs/blob/master/examples/restore.js
For some strange reason sid
and rid
properties are undefined, so you can get them like this:
var sid = chatObj.connection._proto.sid;
var rid = chatObj.connection._proto.rid;
Another way is to get them directly from every XML message sent to the connection by overriding xmlOutput :
connection.xmlOutput = function (e) {
rid = $(e).attr('rid');
sid = $(e).attr('sid');
};
