XMPP multiple chat
Why is group chat such an awkward thing in XMPP? | Ignite Realtime
7.4 Sending a Message to All OccupantsAn occupant sends a message to all other occupants in the room by sending a message of type "groupchat" to the <room@service> itself (a service MAY ignore or reject messages that do not have a type of "groupchat"). In a moderated room, this privilege is restricted to occupants with a role of participant or higher. Example 44. Occupant Sends a Message to All Occupants <message from=‘[email protected]/pda’ id=‘hysf1v37’ to=‘[email protected]’ type=‘groupchat’> <body>Harpier cries: ’tis time, ’tis time.</body> </message> |
然后发送的内容为：
<message type="groupchat" to="[email protected]"><body>To all</body></message> |
结果出错：
<message from="[email protected]" to="[email protected]/842f0050" type="error" xmlns="jabber:client"> <body>To all users</body> <error code="406" type="modify"><not-acceptable xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error> </message> |
搜：

Entering a Room － XEP-0045: Multi-User Chat
“
Entering a Room
7.2.1 Groupchat 1.0 Protocol
In order to participate in the discussions held in a multi-user chat room, a user MUST first become an occupant by entering the room. In the old groupchat 1.0 protocol, this was done by sending presence with no ‘type’ attribute to <room@service/nick>, where "room" is the room ID, "service" is the hostname of the chat service, and "nick" is the user’s desired nickname within the room:
Example 18. User Seeks to Enter a Room (groupchat 1.0)
<presence<br /> from='[email protected]/pda'<br /> id='ng91xs69'<br /> to='[email protected]/thirdwitch'/><br />
In this example, a user with a full JID of "[email protected]/pda" has requested to enter the room "coven" on the "chat.shakespeare.lit" chat service with a room nickname of "thirdwitch".
If the user does not specify a room nickname (note the bare JID on the ‘from’ address in the following example), the service MUST return a <jid-malformed/> error:
Example 19. No Nickname Specified
<presence<br /> from='[email protected]'<br /> id='273hs51g'<br /> to='[email protected]/pda'<br /> type='error'><br /> <error by='[email protected]' type='modify'><br /> <jid-malformed xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/><br /> </error><br /></presence><br />
Note: The presence stanza used to join a room MUST NOT possess a ‘type’ attribute, i.e., it must be available presence. For further discussion, see the Presence business rules.
7.2.2 Basic MUC Protocol
Compliant multi-user chat services MUST accept the foregoing as a request to enter a room from any client that knows either the groupchat 1.0 protocol or the multi-user chat (MUC) protocol; however, MUC clients SHOULD signal their ability to speak the MUC protocol by including in the initial presence stanza an empty <x/> element qualified by the ‘http://jabber.org/protocol/muc‘ namespace (note the absence of the ‘#user’ fragment):
Example 20. User Seeks to Enter a Room (Multi-User Chat)
<presence<br /> from='[email protected]/pda'<br /> id='n13mt3l'<br /> to='[email protected]/thirdwitch'><br /> <x xmlns='http://jabber.org/protocol/muc'/><br /></presence><br />
Before attempting to enter the room, a MUC-compliant client SHOULD first discover its reserved room nickname (if any) by following the protocol defined in the Discovering Reserved Room Nickname section of this document.

去加入room
所以接着就是：
想办法找到XMPPFramework中如何发送Presence
SwiftXMPP MUC XMPPPresence
Stanzas: Presence · fritzy/SleekXMPP Wiki · GitHub
ios – MUC How-to with XMPPFramework – Stack Overflow
结果去发送Presence，对应的用户用：
[email protected]/测试用户2 print("enterRoomPresence=\(enterRoomPresence)") //<presence from="[email protected]/测试用户2" to="[email protected]"/> |
结果出错：
<presence from="[email protected]" to="[email protected]/de8f83ee" type="error" xmlns="jabber:client"> <error code="400" type="modify"><jid-malformed xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error> </presence> |
很明显是：
nickname有误。
去改为：
let userJidWithNickName = curUserFullJid + "/" + "fakeNickName_TestUser1_OnSwiftXMPP" |
结果：
错误依旧。
后来才知道：
原来是此处的服务器openfire端，在设计的时候，强制了nickname就是userId。。。
【已解决】XMPP出错：code 400 jid-malformed xmlns urn:ietf:params:xml:ns:xmpp-stanzas
但是也只是实现了：
发送presence给group，表示进入房间room了
接着还要去实现群发消息：
［总结］
最后是个人user发送给room＝＝group：
<message from="[email protected]/user-1f4857d8-5ea8-434e-8e7c-3f8d20f1f2cf" to="[email protected]" type="groupchat"><body>Crifan user2 send to group a11838ca</body></message> |
然后即可收到：
发送成功时的didSendMessage，user发送给group的：
<message from="[email protected]/user-1f4857d8-5ea8-434e-8e7c-3f8d20f1f2cf" to="[email protected]" type="groupchat"><body>Crifan user2 send to group a11838ca</body></message> |
然后didReceiveMessage中，group也会发回给自己该消息的：
<message xmlns="jabber:client" from="[email protected]/user-1f4857d8-5ea8-434e-8e7c-3f8d20f1f2cf" to="[email protected]/b9378e86" type="groupchat"><body>Crifan user2 send to group a11838ca</body></message> |
即可成功实现消息发送给聊天室＝＝room＝＝group＝＝组
然后同理，也可以实现，其他XMPP客户端（Mac下的Adium）发送消息到聊天室中时，当前代码（对应的iOS模拟器）中也可以收到
对应的消息是：
didReceiveMessage中收到的：
<message xmlns="jabber:client" type="groupchat" id="purple87418a29" to="[email protected]/b9378e86" from="[email protected]/user-09b740d4-45f9-499a-8c84-0ac707a115f5"><body>从Mac的XMPP客户端Adium中发送给聊天室a11838ca</body><html xmlns="http://jabber.org/protocol/xhtml-im"><body><p><span style="font-family: PingFang SC; font-size: medium;">从</span>Mac的XMPP客户端Adium中发送给聊天室a11838ca</p></body></html></message> |
如此，即可实现，双向的，发送和接收聊天室的消息，实现群组聊天了。
对应的为：
加入群组聊天之前，先要进入房间，表明自己在线：
if newConversationItem.msgTVC.contactItem.type == ContactType.Group { //if room, should enter into room first before chat //send presence to room let enterRoomPresence:XMPPPresence = XMPPPresence() let curUserFullJid = gCurrentLoginedUserId + "@" + StrServerDomain print("curUserFullJid=\(curUserFullJid)") //[email protected] enterRoomPresence.addAttributeWithName("from", stringValue: curUserFullJid) let roomFullJid = newConversationItem.msgTVC.contactItem.id + "@" + StrServerConferenceDomain print("roomFullJid=\(roomFullJid)") //group-7f1ad5cd-8f18-4c5e-9fe4-604c3e5b1ab8@conference.jiandao.im let roomJidWithName = roomFullJid + "/" + gCurrentLoginedUserId print("roomJidWithName=\(roomJidWithName)") enterRoomPresence.addAttributeWithName("to", stringValue: roomJidWithName) //DDXMLElement let xXmlnsElement:DDXMLElement = DDXMLElement(name: "x", xmlns: "http://jabber.org/protocol/muc") print("xXmlnsElement=\(xXmlnsElement)") //<x xmlns="http://jabber.org/protocol/muc"/> enterRoomPresence.addChild(xXmlnsElement) print("enterRoomPresence=\(enterRoomPresence)") /* Mac Adium enter the Room: <presence from="[email protected]/licrifandeMacBook-Pro" to="group-26e98e34-3f49-4914-8acd-34354bf23b03@conference.jiandao.im/user-59e68fc0-39c3-4fb3-afef-7a7244d0e87d"><c hash="sha-1" node="http://pidgin.im/" ver="DdnydQG7RGhP9E3k9Sf+b+bF0zo=" xmlns="http://jabber.org/protocol/caps"/> <x xmlns="http://jabber.org/protocol/muc"><history since="2015-12-04T03:14:47Z"/></x> </presence> */ //<presence from="[email protected]" to="group-a11838ca-a741-4d2d-ad5c-477c87400ad0@conference.jiandao.im/user-1f4857d8-5ea8-434e-8e7c-3f8d20f1f2cf"><x xmlns="http://jabber.org/protocol/muc"/></presence> xmppStream().sendElement(enterRoomPresence) } |
供参考。
之前再去发送消息：
func sendMessage(){ print("sendMessage") let messageStrToSend:String? = inputMessageTextField.text print("messageStrToSend=\(messageStrToSend)") if (messageStrToSend != nil) && (messageStrToSend?.lengthOfBytesUsingEncoding(NSUTF8StringEncoding) > 0) { let messageXmlElement:DDXMLElement = DDXMLElement.elementWithName("message") as! DDXMLElement let bodyXmlElement:DDXMLElement = DDXMLElement.elementWithName("body") as! DDXMLElement bodyXmlElement.setStringValue(messageStrToSend!) messageXmlElement.addChild(bodyXmlElement) let fromJid:String = gCurrentLoginedUserId + "@" + StrServerDomain print("fromJid=\(fromJid)") //[email protected] let fromJidWithNickname:String = fromJid + "/" + gCurrentLoginedUserId //[email protected]/user-1f4857d8-5ea8-434e-8e7c-3f8d20f1f2cf messageXmlElement.addAttributeWithName("from", stringValue: fromJidWithNickname) var chatTypeStr:String = "chat" //id is user/group/topic let sendToId:String = contactItem.id print("sendToId=\(sendToId)") //group-7f1ad5cd-8f18-4c5e-9fe4-604c3e5b1ab8 //TODO: maybe need append resource for full JID? var sentToFullJidStr:String = "" if contactItem.type == ContactType.Person { sentToFullJidStr = sendToId + "@" + StrServerDomain }else if contactItem.type == ContactType.Group { //group-c7b68ce4-bbe1-430d-b736-dd7eec6c4413@conference.jiandao.im sentToFullJidStr = sendToId + "@" + StrServerConferenceDomain chatTypeStr = "groupchat" }else if contactItem.type == ContactType.Topic{ print("TODO: add support topic") } print("sentToFullJidStr=\(sentToFullJidStr)") //group-7f1ad5cd-8f18-4c5e-9fe4-604c3e5b1ab8@conference.jiandao.im messageXmlElement.addAttributeWithName("to", stringValue: sentToFullJidStr) messageXmlElement.addAttributeWithName("type", stringValue: chatTypeStr) xmppStream().sendElement(messageXmlElement) print("messageXmlElement=\(messageXmlElement)") //<message type="chat" to="[email protected]"><body>From 2</body></message> //<message from="[email protected]" to="[email protected]" type="groupchat"><body>To all</body></message> inputMessageTextField.text = "" } } |
服务器会返回给你对应的Presence回应，表明你的身份是参与者：
//when receive friend become online func xmppStream(sender: XMPPStream?, didReceivePresence presence: XMPPPresence?) { print("didReceivePresence") print("presence=\(presence)") //<presence xmlns="jabber:client" from="[email protected]/444cbc62" to="[email protected]/444cbc62"/> //<presence xmlns="jabber:client" from="[email protected]/licrifandeMacBook-Pro" to="[email protected]/444cbc62"><c xmlns="http://jabber.org/protocol/caps" node="http://pidgin.im/" hash="sha-1" ver="DdnydQG7RGhP9E3k9Sf+b+bF0zo="/><x xmlns="vcard-temp:x:update"><photo>aa6e432351442c73d99ca484cd91abc96b1c7bed</photo></x></presence> /* <presence from="[email protected]" to="[email protected]/de8f83ee" type="error" xmlns="jabber:client"> <error code="400" type="modify"><jid-malformed xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error> </presence> */ //<presence xmlns="jabber:client" from="group-a11838ca-a741-4d2d-ad5c-477c87400ad0@conference.jiandao.im/user-1f4857d8-5ea8-434e-8e7c-3f8d20f1f2cf" to="[email protected]/96593ac5"><x xmlns="http://jabber.org/protocol/muc#user"><item jid="[email protected]/96593ac5" affiliation="member" role="participant"/></x></presence> let presenceType:String? = presence?.type() print("presenceType=\(presenceType)") //Optional("available") let prensenceSenderUsername:String? = sender?.myJID.user print("prensenceSenderUsername=\(prensenceSenderUsername)") //Optional("user-7aa7e3c3-bf8f-46e1-8cbe-3a5aad6e9dfb") let presenceFromUsername:String? = presence?.from().user print("presenceFromUsername=\(presenceFromUsername)") //Optional("user-7aa7e3c3-bf8f-46e1-8cbe-3a5aad6e9dfb") //TODO: later add process when use online or offline // if chatDelegate != nil { // if presenceFromUser != myUsername { // if presenceType == "available" { // chatDelegate?.newBuddyOnLine("\(presenceFromUser)" + "@" + "\(loginServer)") // } else if presenceType == "unavailable" { // chatDelegate?.buddyWentOffline("\(presenceFromUser)" + "@" + "\(loginServer)") // } // } // } } |
对应的代理delegate会去处理：
发送了消息时：
//when send new message to friend func xmppStream(sender: XMPPStream!, didSendMessage message: XMPPMessage!) { print("didSendMessage") print("message=\(message)") // if let msgBody: String = message.elementForName("body")?.stringValue() { if let msgTo: String = message.attributeForName("to")?.stringValue() { var sentMessage:Message sentMessage = Message() sentMessage.bubbleMessageType = BubbleMessageType.Sent sentMessage.bubbleMessageMediaType = BubbleMessageMediaType.Text sentMessage.text = msgBody //TODO: update to use real sender header image or optimize to fixed user header image after first init //sentMessage.avatar = UIImage(named:"hdImg_wutao_48x48.jpg")! sentMessage.displayTimestamp = true sentMessage.timestamp = NSDate() // sentMessage.timestampStr = sentMessage.timestamp!.toString("yyyy/MM/dd HH:mm:ss") sentMessage.timestampStr = sentMessage.timestamp.toString("HH:mm:ss") sentMessage.displayUsername = false //TODO: get real display name from here msgFrom==userId //[email protected] let toJidInfo:JidInfo = extarctJidInfoFromFullJid(msgTo) print("toJidInfo=\(toJidInfo)") sentMessage.toJidInfo = toJidInfo if let msgFrom = message.attributeForName("from")?.stringValue() { let fromJidInfo:JidInfo = extarctJidInfoFromFullJid(msgFrom) print("fromJidInfo=\(fromJidInfo)") sentMessage.fromJidInfo = fromJidInfo } if messageDelegate != nil { messageDelegate!.newMessageSent(sentMessage) } } } else { return } } |
接受到了消息时：
