在Xmpp/Openfire中从名册中删除一个朋友 [英] Delete a Friend from Roster in Xmpp/Openfire
问题描述
在我的聊天应用程序中.我正在使用smack库，在订阅管理"的帮助下，我已完成了将朋友添加到特定人员花名册的过程.
In my chat application. I am using smack library , with the help of Subscription Management I have done the part of adding a friend to the Roster of a particular person.
现在，我希望当某人拒绝好友请求时，我向另一个用户发送UNSUBSCRIBE PACKET的请求，而不会从另一个用户的花名册中删除该好友.它只是显示NONE订阅.
Now I want that when some person denies the friend request, I send a UNSUBSCRIBE PACKET to the other user for the same, the friend is not deleted from the roster of the other user. It simply shows NONE subscription.
代码:
Presence unsubscribe = new Presence(Presence.Type.unsubscribe);
unsubscribe.setTo(ABC@ABC.COM);
connection.sendPacket(unsubscribe);
如何从朋友名册中删除该用户.我可以从openfire门户网站上做到这一点，但不知道如何从代码中做到这一点.
How can I delete the user from the Roster of the friend. I can do it from openfire portal but don't know how to do it from code.
推荐答案
在 Smack论坛中，此代码可能有效:
From the Smack forum, this code might work:
RosterPacket packet = new RosterPacket();
packet.setType(IQ.Type.SET);
RosterPacket.Item item = new RosterPacket.Item("ABC@ABC.COM", null);
item.setItemType(RosterPacket.ItemType.REMOVE);
packet.addRosterItem(item);
connection.sendPacket(packet);
