Question

注意：服务器已安装并正在运行流管理。

这是我的代码：

XMPPStreamManagementMemoryStorage *storage1=[[XMPPStreamManagementMemoryStorage alloc] init];
xmppStreamManagement=[[XMPPStreamManagement alloc] initWithStorage:storage1];
xmppStreamManagement.autoResume = YES;
[xmppStreamManagement enableStreamManagementWithResumption:TRUE maxTimeout:5];
[xmppStreamManagement addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppStreamManagement activate:xmppStream];
 [xmppStreamManagement requestAck];

我也实现了委托方法。但我既没有在委托方法中得到回应，也没有看到流管理工作。

它将如何运作以及我们如何验证它？

在这里，如果我在iOS端成功实现了流管理，那么就会自动丢失离线消息

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message

任何帮助将不胜感激。

Answer 1

在iOS应用中启用XMPPStreamManagement非常容易。

使用XMPPStreamManagement初始化您的XMPPStreamManagementMemoryStorage个实例。

XMPPStreamManagementMemoryStorage *xmppSMMS = [[XMPPStreamManagementMemoryStorage alloc] init];
xmppStreamManagement = [[XMPPStreamManagement alloc] initWithStorage:xmppSMMS];

将您的实现类添加为其委托

[xmppStreamManagement addDelegate:self delegateQueue:dispatch_get_main_queue()];

现在，在连接XMPPStream并进行绑定后启用流管理。

[xmppStreamManagement activate:xmppStream];
xmppStreamManagement.autoResume = YES;
[xmppStreamManagement enableStreamManagementWithResumption:YES maxTimeout:0];
[xmppStreamManagement requestAck];

实施委托方法

- (void)xmppStreamManagement:(XMPPStreamManagement *)sender wasEnabled:(NSXMLElement *)enabled{
}

- (void)xmppStreamManagement:(XMPPStreamManagement *)sender wasNotEnabled:(NSXMLElement *)failed{
}

- (void)xmppStreamManagement:(XMPPStreamManagement *)sender didReceiveAckForStanzaIds:(NSArray *)stanzaIds{
}

Answer 2

身份验证成功后，调用流管理。

也不要忘记调用'sendAck（）'方法。

// Stream Management
let xmppSMMS = XMPPStreamManagementMemoryStorage()
xmppStreamManagement = XMPPStreamManagement(storage: xmppSMMS, dispatchQueue: DispatchQueue.main)
xmppStreamManagement.addDelegate(self, delegateQueue: DispatchQueue.main)
xmppStreamManagement.activate(xmppStream)
xmppStreamManagement.autoResume = true
xmppStreamManagement.ackResponseDelay = 0.2
xmppStreamManagement.requestAck()
xmppStreamManagement.automaticallyRequestAcks(afterStanzaCount: 1, orTimeout: 10)
xmppStreamManagement.automaticallySendAcks(afterStanzaCount: 1, orTimeout: 10)
xmppStreamManagement.enable(withResumption: true, maxTimeout: 0)
xmppStreamManagement.sendAck()
xmppStream.register(xmppStreamManagement)
