onvif开发之设备发现功能的实现
忙了一个多月，onvif总算告一段落了。这几个星期忙着其他的项目，也没有好好整理一下onvif的东西。接下来得好好整理一下自己的项目思路和项目经验，同时将自己的一些心得写出来，希望对人有所帮助。
相信大多数兄弟和我一样，onvif开发，最开始做的就是发现功能。这两天登录onvif的官网看才发现，onvif版本在八月份有更新，已经更新到V2.4了，于是下载最新的版本来进行。代码的生成可以详见我的前一篇文章。V2.4版本新增了一个wsdl文件，现在用于生成源码的文件一共有18个。为了保证全功能，最好一次性生成包含所有功能的源码。然后根据最新生成的源码来实现onvif客户端和服务端的发现功能。
1. 创建onvif_test目录。以下这些源码由最新的gsoap（2.8.16）和最新的onvif的wsdl文件（2.4）生成。（截止2013.09.16）
onvif.h
soapClientLib.c
soapServerLib.c
soapC.c
soapClient.c
soapH.h
soapServer.c
soapStub.h
2.以下文件来自gsoap_2.8.16\gsoap-2.8\gsoap
stdsoap2.c
stdsoap2.h
3.以下文件来自gsoap_2.8.16\gsoap-2.8\gsoap\custom
duration.c
4.生成的soapClientLib.c和soapServerLib.c无实际作用，可直接删除。
5.增加自定义文件：
onvif_server.c onvif服务端实现代码
onvif_client.c onvif客户端实现代码
onvif_server_interface.c onvif服务端接口实现
onvif_function.c onvif实现函数，公用
onvif_function.h onvif实现函数，公用
onvif_server.c为服务端的实现代码，主要是定义main函数，服务端主要是监听，并处理和应答消息。
Main函数定义如下：
- int main(int argc,char ** argv)
- {
- printf("[%s][%d][%s][%s] start \n", __FILE__, __LINE__, __TIME__, __func__);
- int count = 0;
- struct soap ServerSoap;
- struct ip_mreq mcast;
- soap_init1(&ServerSoap, SOAP_IO_UDP | SOAP_XML_IGNORENS);
- soap_set_namespaces(&ServerSoap, namespaces);
- printf("[%s][%d][%s][%s] ServerSoap.version = %d \n", __FILE__, __LINE__, __TIME__, __func__, ServerSoap.version);
- if(!soap_valid_socket(soap_bind(&ServerSoap, NULL, ONVIF_LISTEN_PORT, 10)))
- {
- soap_print_fault(&ServerSoap, stderr);
- exit(1);
- }
- mcast.imr_multiaddr.s_addr = inet_addr("239.255.255.250");
- mcast.imr_interface.s_addr = htonl(INADDR_ANY);
- if(setsockopt(ServerSoap.master, IPPROTO_IP, IP_ADD_MEMBERSHIP, (char*)&mcast, sizeof(mcast)) < 0)
- {
- printf("setsockopt error! error code = %d,err string = %s\n",errno,strerror(errno));
- return 0;
- }
- for(;;)
- {
- if(soap_serve(&ServerSoap))
- {
- soap_print_fault(&ServerSoap, stderr);
- }
- soap_destroy(&ServerSoap);
- soap_end(&ServerSoap);
- //客户端的IP地址
- printf("RECEIVE count %d, connection from IP = %lu.%lu.%lu.%lu socket = %d \r\n", count, ((ServerSoap.ip)>>24)&0xFF, ((ServerSoap.ip)>>16)&0xFF, ((ServerSoap.ip)>>8)&0xFF,(ServerSoap.ip)&0xFF, (ServerSoap.socket));
- count++;
- }
- //分离运行时的环境
- soap_done(&ServerSoap);
- return 0;
- }
- int main(int argc,char ** argv)
- {
- printf("[%s][%d][%s][%s] start \n", __FILE__, __LINE__, __TIME__, __func__);
- int count = 0;
- struct soap ServerSoap;
- struct ip_mreq mcast;
- soap_init1(&ServerSoap, SOAP_IO_UDP | SOAP_XML_IGNORENS);
- soap_set_namespaces(&ServerSoap, namespaces);
- printf("[%s][%d][%s][%s] ServerSoap.version = %d \n", __FILE__, __LINE__, __TIME__, __func__, ServerSoap.version);
- if(!soap_valid_socket(soap_bind(&ServerSoap, NULL, ONVIF_LISTEN_PORT, 10)))
- {
- soap_print_fault(&ServerSoap, stderr);
- exit(1);
- }
- mcast.imr_multiaddr.s_addr = inet_addr("239.255.255.250");
- mcast.imr_interface.s_addr = htonl(INADDR_ANY);
- if(setsockopt(ServerSoap.master, IPPROTO_IP, IP_ADD_MEMBERSHIP, (char*)&mcast, sizeof(mcast)) < 0)
- {
- printf("setsockopt error! error code = %d,err string = %s\n",errno,strerror(errno));
- return 0;
- }
- for(;;)
- {
- if(soap_serve(&ServerSoap))
- {
- soap_print_fault(&ServerSoap, stderr);
- }
- soap_destroy(&ServerSoap);
- soap_end(&ServerSoap);
- //客户端的IP地址
- printf("RECEIVE count %d, connection from IP = %lu.%lu.%lu.%lu socket = %d \r\n", count, ((ServerSoap.ip)>>24)&0xFF, ((ServerSoap.ip)>>16)&0xFF, ((ServerSoap.ip)>>8)&0xFF,(ServerSoap.ip)&0xFF, (ServerSoap.socket));
- count++;
- }
- //分离运行时的环境
- soap_done(&ServerSoap);
- return 0;
- }
onvif_server_interface.c 此文件用来定义所有服务端需要填充的接口。这里我们填充__wsdd__Probe接口即可，其他赞不支持的接口可以用宏统一处理。
__wsdd__Probe的填充如下：

6.将wsdd.nsmap改为nsmap.h，并删除其余的*.nsmap(都一样)
7.编写makefile文件。注意在makefile中打开开关DEBUG，以便跟踪日志。
8.tcpdump为gcc环境的抓包工具，调试的时候用。
make编译通过，运行，客户端发现功能ok；
但是服务端的发现功能却不行；别急，这是由于SOAP的版本问题；soap的版本是根据命名空间来自动确定的；在soap结构体的version字段表示soap版本；
以下命名空间表示SOAP1.1版本：
{"SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/", "http://www.w3.org/*/soap-envelope", NULL},
{"SOAP-ENC", "http://schemas.xmlsoap.org/soap/encoding/", "http://www.w3.org/*/soap-encoding", NULL}, //1.1
以下命名空间表示SOAP1.2版本：
{"SOAP-ENV", "http://www.w3.org/2003/05/soap-envelope", "http://schemas.xmlsoap.org/soap/envelope/", NULL},
{"SOAP-ENC", "http://www.w3.org/2003/05/soap-encoding", "http://schemas.xmlsoap.org/soap/encoding/", NULL}, //1.2
注意确定自己当前的命名空间。我们用SOAP1.2版本才能被测试工具发现(ONVIF Device Test Tool version 13.06)。
不清楚可以查看soap_set_namespaces接口和soap_set_local_namespaces接口；
于是将nsmap.h中的命名空间前两行改为：
{"SOAP-ENV", "http://www.w3.org/2003/05/soap-envelope", "http://schemas.xmlsoap.org/soap/envelope/", NULL},
{"SOAP-ENC", "http://www.w3.org/2003/05/soap-encoding", "http://schemas.xmlsoap.org/soap/encoding/", NULL}, //1.2
再编译运行，发现功能ok。
最后，将所用的工具和源码提供给大家，大家根据需要下载。
