Facebook Chat difficulty user's JID

I've a problem connecting to Facebook's XMPP to use chat api. In fact the only problem is that I don't know the JID, sometime user doesn't have provided his username and it won't work simply by settings his/her userID as an JID.

I've tried my own JID from facebook that I use in iChat and it worked perfectly.

So, according to the docs I should rather log user to the chat by using access token instead of username/password.

I'm successfuly logged in, the accesss token is in the form: 18112...|f6daa87...-1392...|qE7...-sD6...

Now I use the XMPPFramework with XMPPStreamFacebook by Eric Chamberlain. This is my method starting the chat

-(void)launchService {
    if (xmppStream) {
        [xmppStream release];
        xmppStream = nil;
    }
    xmppStream = [[XMPPStreamFacebook alloc] init];
    xmpReconnect = [[XMPPReconnect alloc] initWithStream:xmppStream];

    if (xmppRosterStorage) {
        [xmppRosterStorage release];
        xmppRosterStorage = nil;
    }

    xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] init];

    if (xmppRoster) {
        [xmppRoster release];
        xmppRoster = nil;
    }
    xmppRoster = [[XMPPRoster alloc] initWithStream:xmppStream rosterStorage:xmppRosterStorage];

    [xmppStream addDelegate:self];
    [xmppRoster addDelegate:self];
    [xmppRoster setAutoRoster:YES];

    [xmppStream setHostName:@"chat.facebook.com"];
    [xmppStream setHostPort:5222];

    [xmppStream setMyJID:[XMPPJID jidWithString:@"test@chat.facebook.com"]];

    // You may need to alter these settings depending on the server you're connecting to
    allowSelfSignedCertificate开发者_如何学JAVAs = NO;
    allowSSLHostNameMismatch = NO;

    // Uncomment me when the proper information has been entered above.
    NSError *error = nil;
    if (![xmppStream connect:&error]) 
        NSLog(@"Error connecting: %@", error);  
}

and

   - (void)xmppStreamDidConnect:(XMPPStream *)sender {
        NSError *error = nil;
    //  [xmppStream authenticateWithAccessToken:[self appDelegate].token error:&error];

        NSLog(@"---------- xmppStreamDidConnect: ----------");

        isOpen = YES;

        if (![[self xmppStream] authenticateWithAccessToken:[self appDelegate].token error:&error])
        {
            NSLog(@"Error authenticating: %@", error);
        }
    }
- (void)xmppStream:(XMPPStream *)sender didNotAuthenticate:(NSXMLElement *)error
{
    NSLog(@"---------- xmppStream:didNotAuthenticate: ---------- %@ desc %@",error,[error description]);
}
...

In the console I get:

2011-01-15 19:41:06.547 Facebookwebsiteziosfbconnect[81160:207] SEND: <?xml version='1.0'?>
2011-01-15 19:41:06.548 Facebookwebsiteziosfbconnect[81160:207] SEND: <stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0' to='chat.facebook.com'>

2011-01-15 19:41:07.829 Facebookwebsiteziosfbconnect[81160:207] ---------- xmppStream:didNotAuthenticate: ---------- (null) desc (null)

I just want to confirm that if I provided the real login (that I use in iChat) instead of test@chat.facebook.com, and my password authentication in didConnect everything the authentication works.

Does anyone see the problem? Thx in advance.

First of all get the uid of the logged in user using the Facebook SDK for iphone and then use this uid instead of username as JID.

FBUID@chat.facebook.com instead of username@chat.facebook.com

I believe the only way you can use a 3rd party client with FB chat is if the user has created a FB user id.

In addition, just to be sure, after your XMPP authentication you should receive the full JID from the server. something like this

<iq id="0" type="result">
  <bind xmlns="urn:ietf:params:xml:ns:xmpp-bind">
    <jid>example@domain.com/resource</jid>
  </bind>
</iq>

that is the JID you use.
