对于我的 IOS 聊天应用程序，我正在使用 Openfire 服务器，我正在检索特定用户好友列表，但现在我想从 Openfire< 检索所有注册用户/strong=""> 服务器。请帮助我并提前致谢。

最佳答案

最后，我通过使用用户名搜索用户找到了替代答案:

1.对于每个联系人，我都像这样添加 emailid username@domainname。
2.在搜索字符串的地方，如果我们使用域名，那么我们将获得所有注册用户。

//Request
- (void)getDetailsofRegisteredUser {
    
    //To Search Peticular User either by using their name, email or username
    NSString *userBare1  = [[[[self appDelegate] xmppStream] myJID] bare];
    NSXMLElement *query = [NSXMLElement elementWithName:@"query"];
    [query addAttributeWithName:@"xmlns" stringValue:@"jabber:iq:search"];
    
    NSXMLElement *x = [NSXMLElement elementWithName:@"x" xmlns:@"jabber:x:data"];
    [x addAttributeWithName:@"type" stringValue:@"submit"];
    
    NSXMLElement *formType = [NSXMLElement elementWithName:@"field"];
    [formType addAttributeWithName:@"type" stringValue:@"hidden"];
    [formType addAttributeWithName:@"var" stringValue:@"FORM_TYPE"];
    [formType addChild:[NSXMLElement elementWithName:@"value" stringValue:@"jabber:iq:search" ]];
    
    NSXMLElement *userName = [NSXMLElement elementWithName:@"field"];
    [userName addAttributeWithName:@"var" stringValue:@"Username"];
    [userName addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1" ]];
    
    NSXMLElement *name = [NSXMLElement elementWithName:@"field"];
    [name addAttributeWithName:@"var" stringValue:@"Name"];
    [name addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
    
    NSXMLElement *email = [NSXMLElement elementWithName:@"field"];
    [email addAttributeWithName:@"var" stringValue:@"Email"];
    [email addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
    
    //Here in the place of SearchString we have to provide registered user name or emailid or username(if it matches in Server it provide registered user details otherwise Server provides response as empty)
    NSXMLElement *search = [NSXMLElement elementWithName:@"field"];
    [search addAttributeWithName:@"var" stringValue:@"search"];
    [search addChild:[NSXMLElement elementWithName:@"value" stringValue:[NSString stringWithFormat:@"%@", SearchString]]];
    
    [x addChild:formType];
    [x addChild:userName];
    [x addChild:name];
    [x addChild:email];
    [x addChild:search];
    [query addChild:x];
    
    NSXMLElement *iq = [NSXMLElement elementWithName:@"iq"];
    [iq addAttributeWithName:@"type" stringValue:@"set"];
    [iq addAttributeWithName:@"id" stringValue:@"searchByUserName"];
    [iq addAttributeWithName:@"to" stringValue:[NSString stringWithFormat:@"search.%@",DOMAIN_NAME]];
    [iq addAttributeWithName:@"from" stringValue:userBare1];
    [iq addChild:query];
    [[[self appDelegate] xmppStream] sendElement:iq];
    
}

//We will get response here

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
    
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
    NSLog(@"searched format %@", iq);

}

关于带有 Openfire 服务器的 iOS XMPP 框架获取所有注册用户，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20279558/
