xmpp协议之type状态码表示属性

2024-12-09 技术教程

简单扼要，主要简单介绍到xmpp中的presence

表示XMPP状态的packet。每一个presence都有一个状态。用枚举类型Presence.Type的值表示:

available --(默认)用户空闲状态

unavailable--用户没空看消息

subscribe--请求加别人为好友

subscribed--确认别人对自己的好友请求

unsubscribe--请求删除好友

unsubscribed--拒绝对方的添加请求

error --当前状态packet有错误

内嵌两个Presence.Mode 和Presence.Type。可以使用setStatus自定义当前的状态

小例子：

加好友

//添加好友#pragma mark 加好友- (void)XMPPAddFriendSubscribe:(NSString *)name{ //XMPPHOST 就是服务器名，主机名 NSXMLElement *mes = [NSXMLElement elementWithName:@"presence"]; [mes addAttributeWithName:@"xmlns" stringValue:@"jabber:client"]; //消息类型 [mes addAttributeWithName:@"type" stringValue:@"subscribe"]; [mes addAttributeWithName:@"to" stringValue:name]; [mes addAttributeWithName:@"from" stringValue:[NSString stringWithFormat:@"%@@%@",[[ShpadDataCenter AppData] loginname],@"ay130415223308469c09"]]; //发送消息 [[[ShpadXMPPService sharedInstance] xmppStream] sendElement:mes]; }

//定义删除好友XMPP
#pragma mark 加好友
- (void)XMPPDeleteFriendSubscribe:(NSUInteger)row
{
//XMPPHOST 就是服务器名，主机名
NSXMLElement *mes = [NSXMLElement elementWithName:@"presence"];

[mes addAttributeWithName:@"xmlns" stringValue:@"jabber:client"];
//消息类型
[mes addAttributeWithName:@"type" stringValue:@"unsubscribe"];
[mes addAttributeWithName:@"to" stringValue:[(BuddyEntity *)[self._allFriends objectAtIndex:row] userId]];
[mes addAttributeWithName:@"from" stringValue:[NSString stringWithFormat:@"%@@%@",[[ShpadDataCenter AppData] loginname],@"ay130415223308469c09"]];

//发送消息
[[[ShpadXMPPService sharedInstance] xmppStream] sendElement:mes];

}

//定义删除好友XMPP#pragma mark 删除好友- (void)XMPPDeleteFriendSubscribe:(NSUInteger)row{ //XMPPHOST 就是服务器名，主机名 NSXMLElement *mes = [NSXMLElement elementWithName:@"presence"]; [mes addAttributeWithName:@"xmlns" stringValue:@"jabber:client"]; //消息类型 [mes addAttributeWithName:@"type" stringValue:@"unsubscribe"]; [mes addAttributeWithName:@"to" stringValue:[(BuddyEntity *)[self._allFriends objectAtIndex:row] userId]]; [mes addAttributeWithName:@"from" stringValue:[NSString stringWithFormat:@"%@@%@",[[ShpadDataCenter AppData] loginname],@"ay130415223308469c09"]]; //发送消息 [[[ShpadXMPPService sharedInstance] xmppStream] sendElement:mes]; }

//拒绝好友请求xmpp#pragma mark 拒绝好友- (void)XMPPRejectFriendSubscribe:(id) sender{ //XMPPHOST 就是服务器名，主机名 NSXMLElement *mes = [NSXMLElement elementWithName:@"presence"]; [mes addAttributeWithName:@"xmlns" stringValue:@"jabber:client"]; //消息类型 [mes addAttributeWithName:@"type" stringValue:@"unsubscribed"]; [mes addAttributeWithName:@"to" stringValue:[self.userInfo objectForKey:@"userName"]]; [mes addAttributeWithName:@"from" stringValue:[NSString stringWithFormat:@"%@@%@",[[ShpadDataCenter AppData] loginname],@"ay130415223308469c09"]]; //发送消息 [[[ShpadXMPPService sharedInstance] xmppStream] sendElement:mes]; }
