Problemas para crear la habitación xmpp muc: Código 503(servicio no disponible) (1)
Mi código para crear una habitación:
XMPPRoomCoreDataStorage *rosterstorage = [[XMPPRoomCoreDataStorage alloc] init];
XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:rosterstorage jid:[XMPPJID jidWithString:@"[email protected]/groupchat"] dispatchQueue:dispatch_get_main_queue()];
[xmppRoom activate:[[self appDelegate] xmppStream]];
if ([xmppRoom preJoinWithNickname:@"nameToCreateRoom"])
{
NSLog(@"room created");
[xmppRoom joinRoomUsingNickname:self.userName history:nil];
}
[xmppRoom fetchConfigurationForm];
[xmppRoom configureRoomUsingOptions:nil];
[xmppRoom addDelegate:[self appDelegate] delegateQueue:dispatch_get_main_queue()];

Veo que está creando / uniendo [email protected] y no [email protected]/groupchat como lo especifiqué. Leí que este es probablemente el problema. Sin embargo, he especificado para el jid completo, entonces estoy perdido.
Gracias de antemano a todos los que ayudan.
Primero, mira aquí XEP-0045: Chat multiusuario .
Como puede ver, primero debe descubrir qué capacidades tiene su usuario (XMPPJID) en el servidor Jabber.
Para hacer esto, envíe el siguiente comando a su Servidor Jabber:
<iq from=''[email protected]/resource'' id=''some_expression'' to=''jabber.server.com'' type=''get''>
<query xmlns=''http://jabber.org/protocol/disco#items''/>
</iq>
o escrito en objetivo-c usando las funciones de la biblioteca XMPP:
NSError *error = nil;
NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns=''http://jabber.org/protocol/disco#items''/>"
error:&error];
XMPPIQ *iq = [XMPPIQ iqWithType:@"get"
to:[XMPPJID jidWithString:@"jabber.server.com"]
elementID:[xmppStream generateUUID] child:query];
[xmppStream sendElement:iq];
Ahora escucha la respuesta del servidor en el delegado XMPPStream - (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq y la respuesta del servidor debería ser algo como esto:
<iq from=''jabber.server.com'' id=''some_expression'' to=''[email protected]/resource'' type=''result''>
<query xmlns=''http://jabber.org/protocol/disco#items''>
<item jid=''im.jabber.server.com'' name=''Instant Message Service''/>
<item jid=''conference.jabber.server.com'' name=''Chatroom Service''/>
</query>
</iq>
o objetivo c:
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
if([iq isResultIQ])
{
if([iq elementForName:@"query" xmlns:@"http://jabber.org/protocol/disco#items"])
{
NSLog(@"Jabber Server''s Capabilities: %@", [iq XMLString]);
}
}
}
Ahora, para cada artículo devuelto, envíe IQ a su servidor por sus propiedades y descubra cuál es el tipo de conferencia , algo como esto:
<iq from=''[email protected]/resource'' id=''some_expression'' to=''conference.jabber.server.com'' type=''get''>
<query xmlns=''http://jabber.org/protocol/disco#info''/>
</iq>
o en el objetivo c:
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
if([iq isResultIQ])
{
if([iq elementForName:@"query" xmlns:@"http://jabber.org/protocol/disco#items"])
{
NSXMLElement *query = [iq childElement];
NSArray *items = [query children];
for(NSXMLElement *item in items)
{
NSError *error = nil;
NSXMLElement *sendQuery = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns=''http://jabber.org/protocol/disco#info''/>"
error:&error];
XMPPIQ *sendIQ = [XMPPIQ iqWithType:@"get"
to:[XMPPJID jidWithString:[item attributeStringValueForName:@"jid"]]
elementID:[xmppStream generateUUID]
child:sendQuery];
[xmppStream sendElement:sendIQ];
}
}
}
}
Escuche las respuestas del servidor:
<iq from=''conference.jabber.server.com'' id=''some_expression'' to=''[email protected]/resource'' type=''result''>
<query xmlns=''http://jabber.org/protocol/disco#info''>
<identity category=''conference'' name=''Server Group Chat Service'' type=''text''/>
<feature var=''http://jabber.org/protocol/muc''/>
</query>
</iq>
y tomar el dominio de chat grupal de la identidad con category:conference
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
if([iq isResultIQ])
{
if([iq elementForName:@"query" xmlns:@"http://jabber.org/protocol/disco#items"])
{
...
}
else if([iq elementForName:@"query" xmlns:@"http://jabber.org/protocol/disco#info"])
{
NSXMLElement *query = [iq childElement];
NSXMLElement *identity = [query elementForName:@"identity"];
if([[identity attributeStringValueForName:@"category"] isEqualToString:@"conference"])
{
groupChatDomain = [iq fromStr];
}
}
}
}
Finalmente, cuando tenemos el dominio de chat grupal, podemos crear una sala de chat como esta:
XMPPJID *chatRoomJID = [XMPPJID jidWithUser:@"chat_room"
domain:groupChatDomain
resource:@"user"];
XMPPRoomMemoryStorage *roomMemoryStorage = [[XMPPRoomMemoryStorage alloc] init];
XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomMemoryStorage
jid:roomChatJID
dispatchQueue:dispatch_get_main_queue()];
[xmppRoom activate:xmppStream];
[xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppRoom joinRoomUsingNickname:user history:nil];
y agregue el protocolo <XMPPRoomDelegate> en su controlador de vista y sus delegados:
- (void)xmppRoomDidCreate:(XMPPRoom *)sender
- (void)xmppRoomDidDestroy:(XMPPRoom *)sender
- (void)xmppRoom:(XMPPRoom *)sender didConfigure:(XMPPIQ *)iqResult
- (void)xmppRoom:(XMPPRoom *)sender didNotConfigure:(XMPPIQ *)iqResult
- (void)xmppRoomDidJoin:(XMPPRoom *)sender
- (void)xmppRoomDidLeave:(XMPPRoom *)sender
- (void)xmppRoom:(XMPPRoom *)sender occupantDidJoin:(XMPPJID *)occupantJID withPresence:(XMPPPresence *)presence
- (void)xmppRoom:(XMPPRoom *)sender occupantDidLeave:(XMPPJID *)occupantJID withPresence:(XMPPPresence *)presence
- (void)xmppRoom:(XMPPRoom *)sender didReceiveMessage:(XMPPMessage *)message fromOccupant:(XMPPJID *)occupantJID
Nota: antes de invitar a otros usuarios a la sala de chat, debe enviar y confirmar las configuraciones de la sala (se puede invitar a otros usuarios pero no se pueden enviar mensajes).
Entonces puede hacer esto después de que se crea Room (delegate - (void)xmppRoomDidCreate:(XMPPRoom *)sender se llama al - (void)xmppRoomDidCreate:(XMPPRoom *)sender ) o su usuario se ha unido (delegate - (void)xmppRoomDidJoin:(XMPPRoom *)sender se llama al - (void)xmppRoomDidJoin:(XMPPRoom *)sender ) a Chat Room.
Para enviar y confirmar la configuración de la sala, realice una de las siguientes acciones:
- (void)xmppRoomDidCreate:(XMPPRoom *)sender
{
[sender configureRoomUsingOptions:nil];
}
o
- (void)xmppRoomDidJoin:(XMPPRoom *)sender
{
[sender configureRoomUsingOptions:nil];
}
Envíe nil para aceptar opciones predeterminadas o puede enviar IQ con sintaxis de la siguiente manera a su servidor:
<iq type=''set'' from=''[email protected]/resource'' id=''some_expression'' to=''[email protected]''>
<query xmlns=''http://jabber.org/protocol/muc#owner''>
<x xmlns=''jabber:x:data'' type=''submit''>
<field var=''FORM_TYPE''>
<value>http://jabber.org/protocol/muc#roomconfig</value>
</field>
<field var=''muc#roomconfig_roomname''>
<value>My Chat Room</value>
</field>
.
.
.
<x>
</query>
</iq>
o codigo objetivo c:
NSError *error = nil;
NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns=''http://jabber.org/protocol/muc#owner''/>"
error:&error];
NSXMLElement *x = [NSXMLElement elementWithName:@"x"
xmlns:@"jabber:x:data"];
[x addAttributeWithName:@"type" stringValue:@"submit"];
NSXMLElement *field1 = [NSXMLElement elementWithName:@"field"];
[field1 addAttributeWithName:@"var" stringValue:@"FORM_TYPE"];
NSXMLElement *value1 = [NSXMLElement elementWithName:@"value"
stringValue:@"http://jabber.org/protocol/muc#roomconfig"];
[field1 addChild:value1];
NSXMLElement *field2 = [NSXMLElement elementWithName:@"field"];
[field2 addAttributeWithName:@"var" stringValue:@"muc#roomconfig_roomname"];
NSXMLElement *value2 = [NSXMLElement elementWithName:@"value"
stringValue:@"My Chat Room"];
[field2 addChild:value2];
//Add other fields you need, just like field1 and field2
[x addChild:field1];
[x addChild:field2];
[query addChild:x];
NSXMLElement *roomOptions = [NSXMLElement elementWithName:@"iq"];
[roomOptions addAttributeWithName:@"type" stringValue:@"set"];
[roomOptions addAttributeWithName:@"id" stringValue:[xmppStream generateUUID];
[roomOptions addAttributeWithName:@"to" stringValue:@"[email protected]"];
[roomOptions addChild:query];
[sender configureRoomUsingOptions:roomOptions];
