XMPP框架的使用及原理简介

来源：互联网发布：程序员的美剧编辑：程序博客网时间：2024/04/29 13:53

XMPP是基于XML协议的分散型通讯网络,只要服务器的协议相同,服务器就可以和服务器通信;

XMPP的核心就是XML流传传输协议;

XMPP是C/S 架构;

XMPP中对应的模块会吧数据从服务器拿出来,然后放到本地数据库,我们开发只需要获取本地服务器的数据.

XMPP----------可扩展通讯和标示协议

==================

连接服务器,登录,注册

// 1. 初始化XMPPStream

-(void)setupXMPPStream;

// 2.连接到服务器

-(void)connectToHost;

// 3.连接到服务成功后，再发送密码授权

-(void)sendPwdToHost;

// 4.授权成功后，发送"在线"消息

-(void)sendOnlineToHost;

======================

xmpp的一般开发步骤:

1.导入指定模块的头文件

2.创建导入的指定模块的对象

3.设置参数

4.设置代理 (需要代理才设置)

5.激活模块

=================================

0054电子明片(个人资料)的设置:

个人资料功能模块------XMPPVcardTempModule.h

个人资料的存储集合----------XMPPvCardTemp *myvCardTemp,是XMPPVcardTempModule的一个属性;

个人资料的数据库存储-------XMPPvCardCoreDataStorage.h

个人资料数据库对象-----------XMPPvCardTempCoreDataStorageObject.h

头像功能模块-----XMPPvCardAVatarModule.h

头像数据存储对象-----XMPPvCardAvatarCoreDataStorageObject.h

@property (nonatomic, strong)XMPPvCardCoreDataStorage *vCardStorage;//电子名片的数据存储

@property (nonatomic, strong)XMPPvCardAvatarModule *avatar;//头像模块

@property (nonatomic, strong)XMPPvCardTempModule *vCard;//电子名片模块

_xmppStream = [[XMPPStreamalloc]init];

#warning 每一个模块添加后都要激活

//添加电子名片模块

_vCardStorage = [XMPPvCardCoreDataStoragesharedInstance];

_vCard = [[XMPPvCardTempModulealloc]initWithvCardStorage:_vCardStorage];

//激活

[_vCard activate:_xmppStream];

//添加头像模块

_avatar = [[XMPPvCardAvatarModulealloc]initWithvCardTempModule:_vCard];

[_avatar activate:_xmppStream];

//xmpp提供了一个方法，直接获取个人信息(电子面片的功能模块有一个个人信息的集合属性:XMPPvCardTemp *myvCardTemp)

XMPPvCardTemp *myVCard =vCard.myvCardTemp;

// 设置头像

if(myVCard.photo){

self.headerView.image = [UIImageimageWithData:myVCard.photo];

}

// 设置昵称

self.nickNameLabel.text = myVCard.nickname;

// 设置微信号[用户名]

NSString *user = [WCUserInfosharedWCUserInfo].user;

self.weixinNumLabel.text = [NSStringstringWithFormat:@"微信号:%@",user];

//更新这个方法内部会实现数据上传到服务器，无需程序自己操作

[vCardupdateMyvCardTemp:myvCard];

================

心跳检测模块-----XMPPAutoPing.h

自动重连模块--------XMPPReconnect.h;

@property (nonatomic, strong)

XMPPReconnect *reconnect;// 自动连接模块

//添加自动连接模块

_reconnect = [[XMPPReconnectalloc]init];

[_reconnect activate:_xmppStream];

===================================

花名册模块--------XMPPRoster.h

好友实体数据库存储--------XMPPRosterCoreDataStorage.h

好友实体对象-----XMPPUserCoreDataStorageObject.h

@property (nonatomic, strong)XMPPRosterCoreDataStorage *rosterStorage;//花名册数据存储

@property (nonatomic, strong)XMPPRoster *roster;//花名册模块

//添加花名册模块【获取好友列表】

_rosterStorage = [[XMPPRosterCoreDataStoragealloc]init];

_roster = [[XMPPRosteralloc]initWithRosterStorage:_rosterStorage];

[_roster activate:_xmppStream];

//方法一: 通过上下文获取好友数据

// 1.获取对象管理上下文【关联到数据库XMPPRoster.sqlite】

NSManagedObjectContext *context =rosterStorage.mainThreadManagedObjectContext;

// 2.FetchRequest【查哪张表】通过实体(相当于表)查找

NSFetchRequest *request = [NSFetchRequestfetchRequestWithEntityName:@"XMPPUserCoreDataStorageObject"];

// 3.设置过滤和排序

// 过滤当前登录用户的好友

NSString *jid = [WCUserInfosharedWCUserInfo].jid;

NSPredicate *pre = [NSPredicatepredicateWithFormat:@"streamBareJidStr = %@",jid];

request.predicate = pre;

//排序

NSSortDescriptor *sort = [NSSortDescriptorsortDescriptorWithKey:@"displayName"ascending:YES];

request.sortDescriptors = @[sort];

// 4.执行请求获取数据集合(集合里面的元素都是XMPPUserCoreDataStorageObject类型)

self.friends = [contextexecuteFetchRequest:requesterror:nil];

NSLog(@"%@",self.friends);

方法二:通过查询控制器查询获取

<NSFetchedResultsControllerDelegate>协议

{

NSFetchedResultsController *_resultsContrl;

}

// 1.上下文【关联到数据库XMPPRoster.sqlite】

NSManagedObjectContext *context =rosterStorage.mainThreadManagedObjectContext;

// 2.FetchRequest【查哪张表】

NSFetchRequest *request = [NSFetchRequestfetchRequestWithEntityName:@"XMPPUserCoreDataStorageObject"];

// 3.设置过滤和排序

// 过滤当前登录用户的好友

NSString *jid = [WCUserInfosharedWCUserInfo].jid;

NSPredicate *pre = [NSPredicatepredicateWithFormat:@"streamBareJidStr = %@",jid];

request.predicate = pre;

//排序

NSSortDescriptor *sort = [NSSortDescriptorsortDescriptorWithKey:@"displayName"ascending:YES];

request.sortDescriptors = @[sort];

// 4.执行请求获取数据,获取好友集合(集合里面的元素都是XMPPUserCoreDataStorageObject类型)

_resultsContrl = [[NSFetchedResultsControlleralloc]initWithFetchRequest:requestmanagedObjectContext:contextsectionNameKeyPath:nilcacheName:nil];

_resultsContrl.delegate =self;

NSError *err = nil;

[_resultsContrlperformFetch:&err];

#pragma mark 当数据的内容发生改变后，会调用这个方法

-(void)controllerDidChangeContent:(NSFetchedResultsController *)controller{

WCLog(@"数据发生改变");

//刷新表格

[self.tableViewreloadData];

}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

return_resultsContrl.fetchedObjects.count;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

staticNSString *ID =@"ContactCell";

UITableViewCell *cell = [tableViewdequeueReusableCellWithIdentifier:ID];

// 获取对应好友

//XMPPUserCoreDataStorageObject *friend =self.friends[indexPath.row];

XMPPUserCoreDataStorageObject *friend = _resultsContrl.fetchedObjects[indexPath.row];//通过传控制器获取的好友实体对象

// sectionNum

// “0”- 在线

// “1”- 离开

// “2”- 离线

switch ([friend.sectionNumintValue]) {//好友对象的状态

case 0:

cell.detailTextLabel.text =@"在线";

break;

case 1:

cell.detailTextLabel.text =@"离开";

break;

case 2:

cell.detailTextLabel.text =@"离线";

break;

default:

break;

}

cell.textLabel.text = friend.jidStr;//jid的类型是xxx@aaa.com

return cell;

}

openfire服务器删除好友后,下面这个方法会接收到删除好友的消息后,花名册模块就会吧数据库roster.sqlite相应的好友删除

-(void)controllerDidChangeContent:(NSFetchedResultsController *)controller,

// 删除好友, 实现这个方法，cell往左滑就会有个delete

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{

if (editingStyle ==UITableViewCellEditingStyleDelete) {

WCLog(@"删除好友");

XMPPUserCoreDataStorageObject *friend =_resultsContrl.fetchedObjects[indexPath.row];

XMPPJID *freindJid = friend.jid;

[[WCXMPPTool sharedWCXMPPTool].roster removeUser:freindJid];

}

=============================

在textfield代理方法中

-(BOOL)textFieldShouldReturn:(UITextField *)textField{

// 添加好友

// 1.获取好友账号

NSString *user = textField.text;

WCLog(@"%@",user);

// 判断这个账号是否为手机号码

if(![textField isTelphoneNum]){

//提示

[self showAlert:@"请输入正确的手机号码"];

return YES;

}

//判断是否添加自己

if([user isEqualToString:[WCUserInfosharedWCUserInfo].user]){

[self showAlert:@"不能添加自己为好友"];

return YES;

}

NSString *jidStr = [NSStringstringWithFormat:@"%@@%@",user,domain];

XMPPJID *friendJid = [XMPPJIDjidWithString:jidStr];

//判断好友是否已经存在

if([[WCXMPPToolsharedWCXMPPTool].rosterStorageuserExistsWithJID:friendJidxmppStream:[WCXMPPToolsharedWCXMPPTool].xmppStream]){

[self showAlert:@"当前好友已经存在"];

return YES;

}

// 2.发送好友添加的请求

// 添加好友,xmpp有个叫订阅

[[WCXMPPToolsharedWCXMPPTool].rostersubscribePresenceToUser:friendJid];

return YES;

}

-(void)showAlert:(NSString *)msg{

UIAlertView *alert = [[UIAlertViewalloc]initWithTitle:@"温馨提示"message:msgdelegate:nilcancelButtonTitle:@"谢谢"otherButtonTitles:nil,nil];

[alert show];

}
