如何创建jabber/XMPP代理/日志记录服务？

Jes*_*Jes 5 java xmpp xml-rpc smack

我正在为一家公司工作,该公司正在使用Google Chatback(与我公司案例中的支持员工进行匿名聊天)作为主要的聊天服务提供商.此服务使用XMPP(以前称为Jabber)协议来发送和接收消息.

我们公司有十个支持员工帐户,可以通过我们在我们网站上使用的聊天服务访问它们.员工同时使用Mac OSX和Windows,以及不同操作系统上的不同客户端.聊天也可以通过Android和iOS上的原生应用程序获得.

我们需要一种用于记录聊天会话的服务,我们一直在寻找专有的解决方案,但这些在移动平台上是不受支持的,而且这基本上就是交易破解者.

我决定的解决方案是在消息链中引入另一个链接,记录所有消息.这个想法是服务器通过这个代理发送,根据它的聊天会话记录消息,然后以适当的方式保存这些日志.目前,他们将所有日志存储在Dropbox文件夹中,这是一个容易出错的活动.

理论上,这将允许我们的支持者使用他们选择的任何操作系统/客户端,并且日志将最终在同一个地方.

在使用Smack API进行了一些测试之后,我得出结论,我的XMPP客户端(Android和Windows上的Trillian)都回复了它上次收到消息的资源.这实际上意味着我实现的非常简单的聊天记录器被忽略了.

使用下面的代码与另一个并行运行的客户端进行了测试.只有一个客户端收到该消息.

ConnectionConfiguration config = new ConnectionConfiguration("talk.google.com", 5222, "googlemail.com");
config.setSecurityMode(ConnectionConfiguration.SecurityMode.required);
config.setSASLAuthenticationEnabled(true);
XMPPConnection connection = new XMPPConnection(config);
connection.connect();

Presence presence = new Presence(Presence.Type.unavailable);
connection.login("android_client_username", "android_client_pass");
Message message = new Message("my_test_email@gmail.com");
message.setBody("Hello World!");
connection.sendPacket(message);
connection.sendPacket(presence);
connection.addPacketListener(new PacketListener() {
          public void processPacket(Packet packet) {
             if (packet instanceof Message) {
                Message message = (Message) packet;
                System.out.println(message.getBody()); 
             }
           }
        }, new MessageTypeFilter(Message.Type.chat));

  • 是否可以使用Google Talk服务创建此类代理,即无需托管我们自己的XMPP服务器？
  • 是否可以远程监听服务器上的所有数据包？
  • 如果没有,那么使用开放协议(如XMPP)的匿名基于Web的聊天客户端有哪些替代方案？

感谢您的时间.

如果您不使用 Google Chatback 服务，那么设置您需要的环境相对容易。为了记录 XMPP 消息，聊天必须通过 MUC（多用户聊天）完成。您需要以下组件：

  • 书籍： http: //professionalxmpp.com/
  • HTTP服务器
  • Jabber/XMPP 服务器（例如 ejabberd）
  • 每个支持席位的聊天室
  • 使用perl和Net::Jabber（不是Net::XMPP，因为它不支持MUC）创建脚本/进程/守护进程，它将登录到XMPP服务器并加入适当的聊天室。聊天室中的其他参与者将是您的支持人员之一，也是寻求支持的人员。脚本必须以这样的方式设置，即它在收到 MUC 消息后执行您想要的任何操作（例如存储在数据库中）。这并不是什么工作，因为当您安装 Net::Jabber 时，有一些示例脚本，您只需在其中添加/修改部分代码。
  • 如果您想通过 Web 浏览器聊天，则必须使用 Strope.js 以便通过正确的代理配置通过 HTTP 服务器与 XMPP 服务器建立 BOSH 连接。

除了使用 Net::Jabber 的 Perl 脚本之外，所有这些内容都可以在书中找到。

我也许帮不了什么忙，但如果你决定走这条路，我会帮忙的。如果 Google Chatback 支持 MUC，那么您只需要 Perl/Net::Jabber 部分。
