linux设备上的Onvif 实现5:实现Probe命令检测设备

学习Onvif的最关键步骤就是设备发现,一般来说开发的设备都是客户端,只要能被服务端正确发现就大功告成啦!

本文分别实现了客户端和服务端的识别流程,可以配合起来运行测试。

第一部分:实现Probe检测实例

代码目录:

\\192.168.0.234\work\gaoht\gsoap\test

\\192.168.0.234\work\gaoht\gsoap\probe-sample

Gsoap 2.8.15

onviftest 12.06

 

Wsdl 下载地址:http://www.onvif.org/Documents/Specifications.aspx

选择链接另存为wsdl文件即可。

 

1 创建工作目录\\192.168.0.234\work\gaoht\gsoap\probe-sample,把remotediscovery.wsdlsoapcpp2wsdl2hWS-typemap.dat拷贝到此处。

cp /work/gaoht/gsoap/gsoap-2.8/gsoap/bin/linux386/soapcpp2   ./

cp /work/gaoht/gsoap/gsoap-2.8/gsoap/bin/linux386/ wsdl2h   ./

cp /work/gaoht/gsoap/gsoap-2.8/gsoap/WS/WS-typemap.dat  ./

 

Gsoap 2.8.15版本下的WS-typemap.dat是完整的,支持WS-Discovery

Gsoap 2.8.3下的gsoap/typemap.dat需要手工添加命令空间。这个文件不同导致生成的RemoteDiscoveryBinding.nsmap前缀是不同的。

 

2 运行wsdl2h:

./wsdl2h -s -c  -t WS-typemap.dat -o remotediscovery.h  remotediscovery.wsdl

生成结果是remotediscovery.h

 

3 运行soapcpp2

用到了/gsoap-2.8/gsoap/import 中的头文件,必须指定import路径。

./soapcpp2  -c -L -x -I../gsoap-2.8/gsoap/import  remotediscovery.h

 

生成的文件是:

RemoteDiscoveryBinding.nsmapwsdd.nsmap   这两者是相同的

soapC.c

soapH.h

soapClient.c

soapServer.c

soapStub.h

 

4 拷贝工作所需的文件到工作目录

    gsoap/stdsoap2.c

    gsoap/stdsoap2.h

    gsoap/plugin/wsaapi.c

    gsoap/plugin/wsaapi.h

   gsoap/plugin/wsddapi.c

   gsoap/plugin/ wsddapi.h

   gsoap/plugin/threads.h      这个文件被wsddapi.h包含,

   gsoap/plugin/cdatatype.h    这个文件被wsddapi.h包含

 

5 编写server端程序,创建deviceserver.c,内容如下:

INCLUDE = -I$(GSOAP_ROOT)

SERVER_OBJS = soapC.o stdsoap2.o  soapClient.o soapServer.o md5c.o uuid32.o deviceserver.o  wsddapi.o  wsaapi.o

CLIENT_OBJS = soapC.o stdsoap2.o soapClient.o md5c.o uuid32.o deviceprobe.o 

 

all: server client

server: $(SERVER_OBJS)

         $(CC) $(INCLUDE) -o deviceserver $(SERVER_OBJS)

client: $(CLIENT_OBJS)

         $(CC) $(INCLUDE) -o deviceprobe $(CLIENT_OBJS)

 

clean: 

         rm -f *.o deviceprobe  deviceserver

 

9 直接运行make all,生成应用程序deviceprobedeviceserver

10 运行deviceserver

 

使用onviftest 12.06工具测试:发现了服务器192.168.15.234这个设备。

  

11 运行deviceprobe,收到deviceserver、摄像头的应答。

发出probe命令, 收到服务器deviceserver应答:

 

紧接着又收到了摄像头的应答
