Tigase输出从客户端和服务器的请求应答日志

Tigase改装目标

把Tigase迁移到DAF是我们的目标。DAF（Datou Application Framework）是手机大头的服务器集群应用开发框架，它使用Zeroc ICE作为服务器节点和节点之间的通讯中间件，使用Google Protocol Buffers作为通讯内容格式。

第一日 – 从客户端和服务器之间的通讯开始

在开始的前几天，思路是模糊的，因为对tigase还有太多不了解，所以日记中的一些结论是基于猜测和经验产生的，很可能在继续深入的时候被推翻。所以各位看官发现有重大问题时不必惊慌，以后我会自己发现的。

可以想像，迁移工作分为以下几个重要部分：

XMPP要求entity与entity之间使用xml进行通讯，但DAF要求entity与entity之间使用PB进行通讯。所以在服务端，我们需要把entity和entity（这里的两个entity特指tigase的内部组件或服务）之间的xml通讯修改为pb通讯，或者采用简单一些的方法：干脆不对tigase进行任何拆解，整个一个服务作为DAF中的一个节点。
不管最终方案是否对Tigase进行拆解，都必须对XMPP协议进行转换，转换为大头私有协议，这需要一个协议转换器。
因为大头IM客户端和服务器之间的通讯基于http1.0，所以如果要让老版本客户端兼容，必须借助并修改Tigase 的BOSH实现；或者我们自己为每一个已连接的老客户端实现一个消息栈。
将Tigase的配置框架修改为DAF的配置框架，这个工作应该不难做
将Tigase的启动迁移到DAF的节点启动框架中，这个工作也不难

从上述已想到的工作大项上看，最具挑战性的工作是第一项，工作量无法预估，工作时间更无法预估。

为了顺利得启动第一项工作，首先要了解XMPP协议内容（英文原版和中文翻译版），在阅读中文版的时候发现了一个严重的错误，所以之后开始中英文参照阅读。之后为了实际考察Tigase和XMPP客户端之间的通讯，我使用Pidgin作为XMPP客户端，连接Tigase服务器进行了登录测试。

如何通过日志查看Tigase服务器和Pidgin客户端的通讯日志

添加打印通讯日志代码的最佳位置

打印日志的最佳位置在tigase.net.IOService，IOService中有两个重要方法：

         protectedvoidwriteData(finalString data) { 
       
             // 这个方法里面的代码需要极小调整： 
       
             // 修改前： 
       
             if(data.length() <256) { 
       
                 log.log(Level.FINEST,"Socket: {0}, Writing data ({1}): {2}",newObject[]{socketIO, 
       
                         data.length(), data}); 
       
             }else{ 
       
                 log.log(Level.FINEST,"Socket: {0}, Writing data: {1}",newObject[]{socketIO, 
       
                         data.length()}); 
       
             } 
       
             // 修改后： 
       
             log.log(Level.FINEST,"Socket: {0}, Writing data ({1}): {2}",newObject[]{socketIO, 
       
                     data.length(), data}); 
       
         } 
       
         protectedchar[] readData()throwsIOException { 
       
             // 这个方法里面的代码需要极小调整，： 
       
             if(log.isLoggable(Level.FINEST)) { 
       
             // 修改前： 
       
             log.log(Level.FINEST, 
       
                     "Socket: "+ socketIO +", Decoded character data: "+ cb.array().length); 
       
             // 修改后 
       
             log.log(Level.FINEST, 
       
                         "Socket: "+ socketIO +", Decoded character data: "+ cb.toString()); 
       
             } 
       
         }

修改完代码之后，再编辑Tigase_Home/etc/init.properties文件：

         # 修改前 
       
         --debug = server 
       
         # 修改后 
       
         --debug = net

好了，现在可以用Pidgin进行登录了，在日志里面可以方便得看到通讯内容：
