从ejabberd服务器检索XMPP存档消息的问题(聊天记录) [英] Issue on retrieve the XMPP archived message from ejabberd server(Chat history)

问题描述

我使用以下方法检索聊天记录.

I used the following method to retrieve the chat history.

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.

After call this function I received the two delegates. i.e. if give 20 messages in XMPPResultSet I received 20 times xmppStreamDidFilterStanza(_ sender: XMPPStream) method.

func xmppMessageArchiveManagement(_ xmppMessageArchiveManagement: XMPPMessageArchiveManagement, didFinishReceivingMessagesWith resultSet: XMPPResultSet) {
    print("didFinishReceivingMessagesWith", resultSet)
}
    func xmppStreamDidFilterStanza(_ sender: XMPPStream) {
    debugPrint("xmppStreamDidFilterStanza")
}

func xmppMessageArchiveManagement(_ xmppMessageArchiveManagement:XMPPMessageArchiveManagement，didFinishReceivingMessagesWith resultSet:XMPPResultSet)中的响应

Response in func xmppMessageArchiveManagement(_ 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.

But this method is never called.

func xmppMessageArchiveManagement(_ xmppMessageArchiveManagement: XMPPMessageArchiveManagement, didReceiveMAMMessage message: XMPPMessage) {
  if let body = message.mamResult?.forwardedMessage{
    print("didReceiveMAMMessage", body)
  }
    print("didReceiveMAMMessage", message)
}

推荐答案

根据您的代码，我看到您没有在任何地方保存xmppMAM.试试这个:

Based on your code I see that you don't save xmppMAM anywhere. Try this:

private var xmppMAM: XMPPMessageArchiveManagement?

func getArchieveMessages(forUser user:String){
    xmppMAM = XMPPMessageArchiveManagement.init()

    // Your code
}
