Question

在AOL AIM 7中，在“C：\ Users \ Prakash \ AppData \ Roaming \ acccore \ caches \ users \ UserA”路径下，有一个文件“feedbag”。

该文件不是文本格式。在Notepad ++中打开时，其格式如下图所示。

我们如何解码这些信息？

Feedbag文件可以从以下链接下载： https://drive.google.com/file/d/0B6cirpFZgAoZXzNMR0llenFua00/view?usp=sharing

------------------ update1 ：8月18日----------------- ------------------------

只有当AIM用户在AIM Instant Messenger中唱歌时，才会发现文件feedbag已创建（或在该文件已存在时更新）。如果任何联系人（好友）离线或在线，文件不会更新 - 这将是我们的代码中找到每个Blast Group的确切在线成员的一个很大的限制。

我使用qaninjazz帐户登录AIM IM（显示名称为qaninjazz3）。有一个爆炸组PTGrp，它有四个成员。目前，只有两名成员（qaninjazz和presenqa）在线。

（在我登录AIM IM之前，presenqa用户已在网络浏览器iwantim.com中登录）

我针对创建的neweset feedbag文件运行代码，但它没有列出PTGrp的任何成员。我在这里附上了这个测试的输出： https://drive.google.com/file/d/0B6cirpFZgAoZdV9PekxwdTJjQkk/view?usp=sharing

代码应列出PTGrp的在线成员，但事实并非如此。可能是，AIM本身并没有将最新数据放在文件本身中。

但是，在输出截图中，我们可以看到Group的成员为“age”和“NewAIMUsers”。

但是mr_parker现在不在线 - 这将是一个很大的问题，因为我们只需要在线会员。

“年龄”是在AIM中创建的组，因此它不是爆炸组。

根据所有这些信息，我认为我们不能依靠文件feedbag获取爆炸组的在线成员。

我的基本要求是在用户与该群组聊天时了解AIM Blast Group的参与者（在线会员）。

我想知道是否有任何AOL API或第三方API或oscar API来实时查找blast组的成员。

如果您想了解更多信息，请与我们联系。

Answer 1

AOL Feedbag文件通常包含有关AIM好友列表的信息。

以下文件提供了有关wireformat文件的一些见解，也提供了有关feedbag数据的有线格式的文档 - 并且可能有助于解码名称后面的数据（请参阅有关未知数据的注释）

https://web.archive.org/web/20081224015759/http://dev.aol.com/aim/oscar/#FEEDBAG

我能够弄清楚如何转储好友和群组的名称，好友跟随一个群组，匹配groupdId，groupId == 0不是真正的群组，它包含有关好友的其他元数据或好友列表应用。

对不起，代码在C中，我没有C＃环境。另请注意，FEEDBAG文件是按网络顺序排列的，因此您必须交换＆＃39;如果你在英特尔盒子上，那么整数的字节顺序
