流程

Appro IPNC使用的web服务器是boa。

请仔细理解下面这段话。

boa这个web服务器是GUI界面和IPNC应用程序之间的通信的桥梁。它的责任是从web GUI中接收HTTP请求,并且在解析请求之后将相应的参数和值传递回去。

通过HTTP抓包工具，我们可以更好的理解这段话..

我们使用wireshark，过滤条件是http && ip.src == 192.168.1.11，其中ip是你本机ip。

如上图所示，这就是我们使用IE打开打开IPNC设备IP，成功进入到登录界面时，捕捉到的包。

按照从上到下，我们可以清楚的看到整个请求的流程。

当然这上面是我修改过显示的结果(为了显示中英文的网页)，和原始的不太一致，不过顺序没变。

首先，当然还是index.htm，这在nfs文件系统里的/var/www路径下可发现。

由于需要判断系统语言而选择加载不同web文件(gz)，所以我用自动跳转glogon.cgi代码代替原有的index.htm中的内容。

加载顺序

loadactivex.htm->gLogon.htm->IPNCWebDlls.CAB->gIPNC-ro.gz

我们直接看body标签下的OBJECT标签。CLASSID和CODEBASE分别指定了IPNCWebDlls.CAB在系统中的位置(dll文件)和在web服务器中的位置。如果当前系统找不到这个插件的话，则从web服务器中下载。有则加载。

PARAM标签则是添加/gIPNC-ro.gz对象，这就是TI IPNC Web的主体文件。而上面的IPNCWebDlls.CAB文件则是网页中播放rtsp的ActiveX插件。

所以关于TI IPNC的Web开发，都是围绕这两个文件来进行的。

在TI IPNC Web网页之GoDB开发环境此文列出的文件列表中，在GUI/docs中有一个文档为

GUI_Keywords_IPNC.xls，一开始看上去你可能有些摸不着头脑。没听说boa服务器下的网页需要什么关键字。原来，IPNC RDK中，boa是修改过，配合GoDB界面来改的，所以这份关键字存在与boa和GoDB工程中的代码中，一一对应的。

我们再次使用wireshark进行抓包，会发现一些东西：

下面这幅图是在登录成功之后抓到包...

先从ini.htm这个url来分析，你不用在文件系统里面寻找了，找不到这个文件的，他是直接在boa代码里面分析处理的。

web浏览器发出请求然后返回(也就是HTTP Reuqst和HTTP Repsonse)。

关于HTTP协议可参考这篇文章HTTP Request header

ini.htm的作用是返回所有关键字的值，然后GoDB将其保存起来，供各个页面读取。

Authorization: Basic YWRtaW46YWRtaW4xMjM=

这里使用的认证方式是：Basic access authentication

这种认证方式，一句话评价，只能防住电脑小白...

接下来是

vb.htm?paratest=keyword

这样的形式查询具体某个关键字的值，有那些关键字，那就得查询GUI_Keywords_IPNC.xls这个文档了...

当然关键字的查询是通过

vb.htm?keyword这样的形式。百思不得其解，从boa代码里面分析的话，原作者一开始采用这样的方式获取各个关键字值，但是后面发现这样需要定义太多重复函数，就采取上面的形式...

总之，通过这样的http请求，GoDB可以获取关键字的值然后填充各个控件。

然后通过

vb.htm?keyword1=xx&keyword2=xxx

这样的形式，进行设置。
