openfire+smack添加好友申请及好友对申请响应监听

来源：互联网发布：男士冬天护肤知乎编辑：程序博客网时间：2024/05/22 06:39

Openfire添加好友申请通过发送Presence包实现，其中Presence包的Type含有七个状态：subscribe订阅、subscribed同意订阅、unsubscribe取消订阅、unsubscribed拒绝订阅、unavailable下线、probe探测、error错误；

PacketFiler过滤器，主要用于过滤出Presence包；

PacketListener监听器，监听服务器发来的消息；

Roster对象，可以理解为保存好友的花名册，接收好友请求的三种模式：Roster.SubscriptionMode.accept_all接受所有、Roster.SubscriptionMode.reject_all拒绝所有、Roster.SubscriptionMode.manual手动处理所有；

Openfire的ofroster表的字段包括sub订阅、ask是否有发送订阅请求、rec是否有接受订阅请求；

sub订阅：

-1 remove 发送删除用户请求

0 none 用户没有建立好友关系

1 to 发送订阅请求且请求被接受

2 from 接受好友订阅请求

3 both 双方互为好友关系

ask是否有发送订阅请求：

-1 null 没有发送好友请求

0 subscribe 发送好友订阅请求但没回复

1 unsubscribe 发送取消订阅好友请求

rec是否有接受订阅请求：

-1 null 没有收到好友订阅请求

1 sub 收到好友订阅请求但没回复

2 unsub 收到好友取消订阅请求

下面可以对照ofroster表看两个例子，好友状态就容易理解了：

openfireuser和ericfantastic这两个用户，ID32：openfireuser对于ericfantastic而言其状态为to，发送订阅请求并且已经被接受，此时ericfantastic可以接收到openfireuser的所有信息包括上线、下线、发送的消息等；ID33：ericfantastic对于openfireuser而且其状态为from，接受好友的订阅请求，对方可以收到你的状态消息，但是你无法收到对方的，必须主动添加才可以。

aaa和hhh这两个用户，sub为3，则已经互为好友，双方都能收到对方的订阅消息。

其他的状态就不一一列举了，对照着字段状态，也是很容易理解的。

贴一个自己做的添加好友及处理请求的Demo，全都在一个AddFriendActivity中实现。
