问题描述
我使用以下方法检索聊天记录。
func getArchieveMessages(forUser user:String){
let xmppMAM = XMPPMessageArchiveManagement.init()
xmppMAM.addDelegate(self,delegateQueue: .main)
xmppMAM.activate(stream)
let xmppDateString = NSDate().addingTimeInterval(-(3 * 24 * 60 * 60)).xmppDateTimeString
var fields: [XMLElement] = []
let start = XMPPMessageArchiveManagement.field(withVar: "end",type: nil,andValue: xmppDateString)
fields.append(start)
let value = DDXMLElement(name: "value",stringValue: user)
let child = DDXMLElement(name: "field")
child.addChild(value)
child.addAttribute(withName: "var",stringValue: "with")
let set = XMPPResultSet(max: 20,before: "")
fields.append(child)
xmppMAM.retrieveMessageArchive(at: nil,withFields: fields,with: set)
}
调用此函数后，我收到了两个代表。即如果在XMPPResultSet中给出20条消息，我会收到20次 xmppStreamDidFilterStanza（_ sender：XMPPStream）方法。
func xmppMessageArchiveManagement(_ xmppMessageArchiveManagement: XMPPMessageArchiveManagement,didFinishReceivingMessagesWith resultSet: XMPPResultSet) {
print("didFinishReceivingMessagesWith",resultSet)
}
func xmppStreamDidFilterStanza(_ sender: XMPPStream) {
debugPrint("xmppStreamDidFilterStanza")
}
函数xmppMessageArchiveManagement中的响应（_ xmppMessageArchiveManagement：XMPPMessageArchiveManagement，didFinishReceivingMessagesWith resultSet：XMPPResultSet）
didFinishReceivingMessagesWith <set xmlns="http://jabber.org/protocol/rsm"><count>364</count><first>1603801030936227</first><last>1603948285226175</last></set>
但是永远不会调用此方法。
func xmppMessageArchiveManagement(_ xmppMessageArchiveManagement: XMPPMessageArchiveManagement,didReceiveMAMMessage message: XMPPMessage) {
if let body = message.mamResult?.forwardedMessage{
print("didReceiveMAMMessage",body)
}
print("didReceiveMAMMessage",message)
}
