Question

在我的应用程序中，我需要从 OpenFire 获取所有用户名。

我使用下面的代码，但它没有提供nil数据。

我的 didReceiveIQ 方法出了点问题但是首次使用XMPP，所以不能解决实际问题。

我的获取数据的代码是

- (void)getAllRegisteredUsers {

NSError *error = [[NSError alloc] init];
NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns='http://jabber.org/protocol/disco#items' node='all users'/>"
                                                        error:&error];
XMPPIQ *iq = [XMPPIQ iqWithType:@"get"
                             to:[XMPPJID jidWithString:[NSString stringWithFormat:@"Domain Name with jid"]]
                      elementID:[xmppStream generateUUID] child:query];
[xmppStream sendElement:iq];
}

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
NSXMLElement *queryElement = [iq elementForName: @"query" xmlns: @"http://jabber.org/protocol/disco#items"];

NSLog(@"queryelement %@",queryElement);

if (queryElement) {

    NSLog(@"query in if");
    NSArray *itemElements = [queryElement elementsForName: @"item"];
    NSMutableArray *mArray = [[NSMutableArray alloc] init];
    for (int i=0; i<[itemElements count]; i++) {

        NSString *jid=[[[itemElements objectAtIndex:i] attributeForName:@"jid"] stringValue];
        [mArray addObject:jid];

        NSLog(@"User in OpenFire = %@",jid);

    }

    NSLog(@"mArray = %@",mArray);

}

return NO;
}

赞赏任何形式的帮助......

我正在努力让所有注册用户从openfire进入我的应用程序。我尝试了以上所有方法，但没有帮助我！经过多次尝试后，我得到了一个获得所有注册用户的解决方案...... 这是代码：

- (void)getAllRegisteredUsers {

    NSError *error = [[NSError alloc] init];
    NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns='jabber:iq:roster'/>" error:&error];
    XMPPIQ *iq = [DDXMLElement elementWithName:@"iq"];
    [iq addAttributeWithName:@"type" stringValue:@"get"];
    [iq addAttributeWithName:@"none" stringValue:@"ANY_ID_NAME"];
    [iq addAttributeWithName:@"both" stringValue:@"ANY_ID_NAME"];
    [iq addChild:query];
    [xmppStream sendElement:iq];
}

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq{

    NSXMLElement *queryElement = [iq elementForName: @"query" xmlns: @"jabber:iq:roster"];

    if (queryElement) {
        NSArray *itemElements = [queryElement elementsForName: @"item"];
        NSMutableArray *mArray = [[NSMutableArray alloc] init];
        for (int i=0; i<[itemElements count]; i++) {

            NSString *jid=[[[itemElements objectAtIndex:i] attributeForName:@"jid"] stringValue];
            [mArray addObject:jid];
        }
        NSLog(@"%@",mArray);
    }
    return YES;
}

这对我有用，希望它也适用于其他人...... :)

通过此代码，您可以获得名单（来自开放式服务器的朋友列表）。

   NSXMLElement *query = [NSXMLElement elementWithName:@"query" xmlns:@"jabber:iq:roster"];

   NSXMLElement *iq = [NSXMLElement elementWithName:@"iq"];
   [iq addAttributeWithName:@"type" stringValue:@"get"];
   [iq addChild:query];
   [xmppStream sendElement:iq];

响应将与您期望的相同。

Answer 3

尝试这样的事情：

[xmppRoster addDelegate:self delegateQueue:dispatch_get_main_queue() ] ;
[xmppRoster fetchRoster ] ;

你应该在获取名单之前初始化XMPPRoster：

    xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] init];
//  xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] initWithInMemoryStore];

xmppRoster = [[XMPPRoster alloc] initWithRosterStorage:xmppRosterStorage];

在fetchRoster对象上发送XMPPRoster后，您可以从中获取所有用户名 XMPPRosterDelegate的方法：

- (void)xmppRoster:(XMPPRoster *)sender didReceiveRosterItem:(NSXMLElement *)item

希望这可以提供帮助：]

我有同样的问题，我也将queryElement作为nil。我已经更改了响应代码，以便像这样查看XML：

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
    NSXMLElement *queryElement = [iq elementForName:@"query" xmlns: @"jabber:iq:roster"];
    NSLog(@"IQ: %@",iq);
    if (queryElement) {

        NSArray *itemElements = [queryElement elementsForName: @"item"];
        NSMutableArray *mArray = [[NSMutableArray alloc] init];
        for (int i=0; i<[itemElements count]; i++) {

            NSString *jid=[[[itemElements objectAtIndex:i] attributeForName:@"jid"] stringValue];
            NSLog(@"%@",jid);
            [mArray addObject:jid];
        }
    }
    return NO; 
}
