生成onvif相关的开发代码

一、必备网址
1. Onvif官网：http://www.onvif.org/

2. gsoap官网：http://www.cs.fsu.edu/~engelen/soap.html

二、操作步骤

1. 下载gsoap

在gsoap官网旁边，有sourceforge的链接，去那里下源码。https://sourceforge.net/projects/gsoap2/files/?source=navbar

2、在centos下编译gsoap

编译gsoap需要相关环境：

yum install byacc -y

yum install flex -y

yum install openssl-devel -y
yum install zlib-dev -y
yum install bison-devel -y
yum install zlib-devel -y

然后输入：

./configure --prefix=安装路径

make

make install

至此，安装gsoap完成。

三、生成onvif头文件

进入gsoap的安装目录下的bin中，找到名为wsdl2h的可执行文件。用该可执行文件生成onvif.h头文件有2种方式，在线方式和离线方式。输入：wsdl2h  -h查看帮助

1.在线方式：

 ./wsdl2h -c -s -t typemap.dat -o onvif.h http://www.onvif.org/onvif/ver10/device/wsdl/devicemgmt.wsdl http://www.onvif.org/onvif/ver10/events/wsdl/event.wsdl http://www.onvif.org/onvif/ver10/deviceio.wsdl http://www.onvif.org/onvif/ver20/imaging/wsdl/imaging.wsdl http://www.onvif.org/onvif/ver10/media/wsdl/media.wsdl http://www.onvif.org/onvif/ver10/search.wsdl http://www.onvif.org/onvif/ver10/receiver.wsdl http://www.onvif.org/onvif/ver10/recording.wsdl http://www.onvif.org/onvif/ver10/network/wsdl/remotediscovery.wsdl 

每个链接用空格分隔开。

2.离线方式：

先下载好相关wsdl文件，如remotediscovery.wsdl devicemgmt.wsdl，放到目录下，再执行

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

每个文件同样用空格分隔开。

注：typemap.dat 文件在下载的gsoap解压包内，自己去找。

四、生成开发onvif用原文件

生成onvif.h头文件之后，即可根据soapcpp2命令生成C源文件或者CPP源文件。输入soapcpp2 -h，查看帮助

命令为：

./soapcpp2 -c   onvif.h -x -2 -I gsoap路径:gsoap/import路径 -d 生成后文件存放的路径

如果要生成cpp文件，则为：

./soapcpp2 -cpp onvif.h -x -2 -I gsoap路径:gsoap/import路径 -d 生成后文件存放的路径

注：其中-2参数是选择onvif 1.2 版本, 如果选择-1消息通知就无法被onvif测试工具识别

soapcpp2 的帮助信息见下：

[root@localhost bin]# ./soapcpp2 -h
Usage: soapcpp2 [-0|-1|-2] [-C|-S] [-T] [-L] [-a] [-A] [-b] [-c] [-d path] [-e] [-f N] [-h] [-i] [-I path:path:...] [-k] [-l] [-m] [-n] [-p name] [-s] [-t] [-u] [-v] [-w] [-x] [-y] [-z#] [infile]
