从 libpurple（支撑 Pidgin 的 IM 库）检索另一个用户的状态

Question

我正在尝试在简单网络（Microsoft Office Communicator）上获取另一个人的当前状态。我正在使用 libpurple，围绕 libpurple 构建了一个 C++ 包装器，并且我可以与 SIMPLE 网络上的其他用户发送/接收 IM。我仍然需要获取其他用户的当前状态

这是我当前尝试检索另一个用户的状态。
之前定义并初始化：

PurpleAccount *CommonIM::m_account ->我可以使用此帐户发送消息

// the username of the person I want to get the status of, e.g. 
username = "sip:[email protected]";

//TEST instance 1
PurpleBuddy* newbody1 = purple_buddy_new(m_account, username.c_str(), NULL);
sleep(5);
PurplePresence *p1 = purple_buddy_get_presence(newbody1);

PurpleStatus *status1 = purple_presence_get_active_status(p1);
PurpleStatusType *statusType1 = purple_status_get_type(status1);
PurpleStatusPrimitive prim1 = purple_status_type_get_primitive(statusType1);

switch(prim1)
{
case PURPLE_STATUS_UNSET:
{
    status = "unset";
}
break;
case PURPLE_STATUS_OFFLINE:
{
    status = "offline";
}
break;
case PURPLE_STATUS_AVAILABLE:
{
    status = "available";
}
break;
case PURPLE_STATUS_UNAVAILABLE:
{
    status = "unavailable";
}
break;
case PURPLE_STATUS_INVISIBLE:
{
    status = "invisible";
}
break;
case PURPLE_STATUS_AWAY:
{
    status = "away";
}
break;
case PURPLE_STATUS_EXTENDED_AWAY:
{
    status = "extended away";
}
break;
case PURPLE_STATUS_MOBILE:
{
    status = "mobile";
}
break;
case PURPLE_STATUS_TUNE:
{
    status = "tune";
}
break;
case PURPLE_STATUS_NUM_PRIMITIVES:
default:
{
    status = "unknown";
}
break;
}

//TEST instance 1 complete
cout << _TAG << "Test instance 1: Status for " << username << " is reported as " << status << endl;

此代码始终返回离线状态。就好像紫色在创建新实例后不会刷新好友，它始终保持“离线”状态。在过去的几天里，我深入研究了 libpurple 和 pidgin，试图找到它，但找不到检索状态的“正确”方法。

由于某种原因，从 signed-on 信号调用此函数不起作用。

从 buddy-signed-on 信号调用它对我来说很有效。当然，在这种情况下，将为每个登录好友调用一次...

从“好友登录”信号调用的示例函数：

static void buddy_signed_on(PurpleBuddy *buddy) {
GSList *buddies = purple_blist_get_buddies();
for(; buddies; buddies = buddies->next) {
    PurpleBuddy *b = (PurpleBuddy *) buddies->data;
    PurplePresence *presence = purple_buddy_get_presence(b);
    PurpleStatus *status = purple_presence_get_active_status(presence);
    printf("%s is now %s\n", b->name, purple_status_get_id(status));
    }
}

连接信号：

purple_signal_connect(purple_blist_get_handle(), "buddy-signed-on", &handle,
          PURPLE_CALLBACK(buddy_signed_on), NULL);
