onvif规范的实现：server端Discovery实现，通过OnvifTestTool12.06测试

说明：网上关于ONVIF开发的文章并不多，也更找不到具体的实例来入门学习。只能靠翻阅各种Specification摸索中前进，下面是最近几天的成果。调通了服务端（或者说设备端）的Discovery，使用OnvifTestTool12.06能够搜到我的设备。【来自http://blog.csdn.net/ghostyu】

1、在使用wsdl2h产生头文件前需要修改typemap.dat，

修改的依据在这里：http://www.cs.fsu.edu/~engelen/soap.html，在FAQ页面下的How do I use gSOAP for the ONVIF specifications?

2、根据onvif官网提供的remotediscovery.wsdl产生onvif.h头文件

关于onvif所有的wsdl都在这里：http://www.onvif.org/Documents/Specifications.aspx中的ONVIF WSDL and XML Schemas Specifications一节，虽然可以全部下载为wsdl文件，但是wsdl文件中存在相互依赖的关系，并且是带有存储的依赖，所以最好直接使用url来产生头文件，不要下载下来。

 

 

[html] view plaincopyprint?
  1. wsdl2h -o onvif.h -c -s -t ./typemap.dat http://www.onvif.org/onvif/ver10/network/wsdl/remotediscovery.wsdl  
wsdl2h -o onvif.h -c -s -t ./typemap.dat http://www.onvif.org/onvif/ver10/network/wsdl/remotediscovery.wsdl

 

3、使用onvif.h来产生骨架代码

 

 

[html] view plaincopyprint?
  1. soapcpp2 -c onvif.h -x -I /root/onvif/gsoap-2.8/gsoap/import -I /root/onvif/gsoap-2.8/gsoap/  
soapcpp2 -c onvif.h -x -I /root/onvif/gsoap-2.8/gsoap/import -I /root/onvif/gsoap-2.8/gsoap/

 

4、ProbeMatches代码

这样就创建了基本的服务端和客户端的代码了，下面需要添加具体的代码了。

 

其中包括：

(1)创建组播用的udp socket，绑定组播地址为239.255.255.250，端口为3702，因为ws-discovery的组播地址和端口就是为239.255.255.250和3702

(2)在产生的Probe函数中添加ProbeMatches代码
首先是udp socket

 

[cpp] view plaincopyprint?
  1. int bind_server_udp1(int server_s)  
  2. {  
  3.     struct sockaddr_in local_addr;  
  4.     memset(&local_addr,0,sizeof(local_addr));  
  5.     local_addr.sin_family = AF_INET;  
  6.     local_addr.sin_addr.s_addr = htonl(INADDR_ANY);  
  7.     local_addr.sin_port = htons(3702);  
  8.     return bind(server_s,(struct sockaddr*)&local_addr,sizeof(local_addr));  
  9.   
  10. }  
  11. static int create_server_socket_udp(void)  
  12. {  
  13.     int server_udp;  
  14.     unsigned char one = 1;  
  15.     int sock_opt = 1;  
  16.       
  17.     //server_udp = socket(PF_INET, SOCK_DGRAM, 0);   
  18.     server_udp = socket(PF_INET, SOCK_DGRAM, IPPROTO_UDP);  
  19.     if (server_udp == -1) {  
  20.         printf("unable to create socket\n");  
  21.     }  
  22.   
  23.     /* reuse socket addr */  
  24.     if ((setsockopt(server_udp, SOL_SOCKET, SO_REUSEADDR, (void *) &sock_opt,  
  25.                     sizeof (sock_opt))) == -1) {  
  26.         printf("setsockopt\n");  
  27.     }  
  28.     if ((setsockopt(server_udp, IPPROTO_IP, IP_MULTICAST_LOOP,  
  29.                        &one, sizeof (unsigned char))) == -1) {  
  30.         printf("setsockopt\n");  
  31.     }  
  32.   
  33.     struct ip_mreq mreq;  
  34.     mreq.imr_multiaddr.s_addr = inet_addr("239.255.255.250");  
  35.     mreq.imr_interface.s_addr = htonl(INADDR_ANY);  
  36.   
  37.     if(setsockopt(server_udp,IPPROTO_IP,IP_ADD_MEMBERSHIP,&mreq,sizeof(mreq))==-1){  
  38.         perror("memberchip error\n");  
  39.     }  
  40.   
  41.     return server_udp;  
  42. }  
int bind_server_udp1(int server_s)
{
	struct sockaddr_in local_addr;
	memset(&local_addr,0,sizeof(local_addr));
	local_addr.sin_family = AF_INET;
	local_addr.sin_addr.s_addr = htonl(INADDR_ANY);
	local_addr.sin_port = htons(3702);
	return bind(server_s,(struct sockaddr*)&local_addr,sizeof(local_addr));

}
static int create_server_socket_udp(void)
{
    int server_udp;
	unsigned char one = 1;
	int sock_opt = 1;
	
	//server_udp = socket(PF_INET, SOCK_DGRAM, 0);
    server_udp = socket(PF_INET, SOCK_DGRAM, IPPROTO_UDP);
    if (server_udp == -1) {
        printf("unable to create socket\n");
    }

    /* reuse socket addr */
    if ((setsockopt(server_udp, SOL_SOCKET, SO_REUSEADDR, (void *) &sock_opt,
                    sizeof (sock_opt))) == -1) {
        printf("setsockopt\n");
    }
    if ((setsockopt(server_udp, IPPROTO_IP, IP_MULTICAST_LOOP,
                       &one, sizeof (unsigned char))) == -1) {
        printf("setsockopt\n");
    }

	struct ip_mreq mreq;
	mreq.imr_multiaddr.s_addr = inet_addr("239.255.255.250");
	mreq.imr_interface.s_addr = htonl(INADDR_ANY);

	if(setsockopt(server_udp,IPPROTO_IP,IP_ADD_MEMBERSHIP,&mreq,sizeof(mreq))==-1){
		perror("memberchip error\n");
	}

    return server_udp;
}

需要注意几点：1/设置socket属性SO_REUSEADDR，2、设置socket属性IP_ADD_MEMBERSHIP，目的是让3702的端口能够重复绑定，一家加入组播组。

 

其次是添加ProbeMatches代码
(1)首先复制client的soap_send___wsdd__ProbeMatches函数到服务端来，因为soap_send___wsdd__ProbeMatches已经写好了用于响应Probe消息的框架了，不用白不用啊。
(2)编写__wsdd__Probe函数，添加如下内容

 

[cpp] view plaincopyprint?
  1. int  __wsdd__Probe(struct soap* soap, struct wsdd__ProbeType *wsdd__Probe)  
  2. {  
  3.     DBG("__wsdd__Probe\n");

	soap->header->wsa__RelatesTo->RelationshipType = NULL;
	soap->header->wsa__RelatesTo->__anyAttribute = NULL;

	soap->header->wsa__MessageID =(char *)soap_malloc(soap, sizeof(char) * INFO_LENGTH);
	strcpy(soap->header->wsa__MessageID,_HwId+4);

    /* send over current socket as HTTP OK response: */
	/*测试过，第二参数必须http，action随意*/
    soap_send___wsdd__ProbeMatches(soap, "http://", NULL, &ProbeMatches);
	return SOAP_OK;

}

想要写出上述代码，是一定要了解SOAP格式的，在WS-Discovery中描述了discovery所用的soap格式

 

1首先是了解消息头header和ProbeMatches中的内容，非常重要，可以参考这里http://www.w3.org/Submission/ws-addressing/  最好详细的学习一下，里面的内容非常重要。

2其次需要理解的是，其实当你看完ws-addressing后你会发现，骨架代码中的结构体和SOAP消息中的内容是一一对应的，例如：

结构体osap->header对应SOAP消息的<SOAP-ENV:Header></SOAP-ENV:Header>中的内容，包含在header里的内容当然会包含在SOAP的header内。例如：

结构体soap->header->wsa__RelatesTo对应的是<wsa:RelatesTo></wsa:RelatesTo>。

3最后需要理解的是，在代码中的"__"双下划线一般对应xml中的命名空间的":"，下划线前是命名空间，后是具体内容。

4最后的最后是要详细的阅读ONVIF Core Specification

下图为响应OnvifTestTool的Probe命令的SOAP消息


结合上图再分析代码就亲切多了。在ONVIF Core Specification的7.3.2.2  Scopes 一节描述了onvif需要的Scopes，这个是需要在程序里填充，具体填充什么，文档里说的很明确：


注意点是在太多，随便漏掉一个都可能会导致搜不到设备，下图是非常重要的一个：

SOAP1.1和SOAP1.2所使用的SOAP-ENV是不同的，ONVIF使用的是SOAP1.1，如果soapcpp2产生的nsmap文件中的SOAP-ENV是SOAP1.2版本的话，那么OnvifTestTool是不会识别设备发出的SOAP消息的。

5、该main函数登场了

 

[cpp] view plaincopyprint?
  1. int main()  
  2. {  
  3.     int server_udp;  
  4.       
  5.     int retval=0;  
  6.     struct soap *soap_udp;  
  7.     int fault_flag = 0;  
  8.       
  9.     server_udp = create_server_socket_udp();  
  10.     bind_server_udp1(server_udp);  
  11.     while(1){  
  12.         soap_udp=soap_new();  
  13.         soap_init1(soap_udp, SOAP_IO_UDP);  
  14.         soap_udp->master = server_udp;  
  15.         soap_udp->socket = server_udp;  
  16.         soap_udp->errmode = 0;  
  17.         soap_udp->bind_flags = 1;  
  18.         if (!soap_valid_socket(soap_bind(soap_udp, NULL, 3702, 100)))  
  19.         {      
  20.             soap_print_fault(soap_udp, stderr);  
  21.         }  
  22.         fprintf(stderr,"soap_serve starting..\n");  
  23.         retval = soap_serve(soap_udp); //阻塞在这里   
  24.         fprintf(stderr,"retval=%d\n",retval);  
  25.         if(retval && !(fault_flag))  
  26.         {  
  27.             fault_flag = 1;  
  28.         }  
  29.         else if(!retval)  
  30.         {  
  31.             fault_flag = 0;  
  32.         }  
  33.         soap_destroy(soap_udp);  
  34.         soap_end(soap_udp);  
  35.         soap_done(soap_udp);  
  36.         free(soap_udp);  
  37.     }  
  38. }  
int main()
{
	int server_udp;
	
	int retval=0;
	struct soap *soap_udp;
	int fault_flag = 0;
	
	server_udp = create_server_socket_udp();
	bind_server_udp1(server_udp);
	while(1){
		soap_udp=soap_new();
		soap_init1(soap_udp, SOAP_IO_UDP);
		soap_udp->master = server_udp;
		soap_udp->socket = server_udp;
		soap_udp->errmode = 0;
		soap_udp->bind_flags = 1;
		if (!soap_valid_socket(soap_bind(soap_udp, NULL, 3702, 100)))
		{	 
			soap_print_fault(soap_udp, stderr);
		}
		fprintf(stderr,"soap_serve starting..\n");
		retval = soap_serve(soap_udp); //阻塞在这里
		fprintf(stderr,"retval=%d\n",retval);
		if(retval && !(fault_flag))
		{
			fault_flag = 1;
		}
		else if(!retval)
		{
			fault_flag = 0;
		}
		soap_destroy(soap_udp);
		soap_end(soap_udp);
		soap_done(soap_udp);
		free(soap_udp);
	}
}

soap_server函数会一直阻塞，直到接收到SOAP消息，并且该处理是一次性的，所以要将将soap_server放到while里或者独立的线程中。
最后编译运行

 

make server

./discovery.tmp

单击OnvifTestTool的Discover Devices，运行discovery.tmp的中会打印调试信息，如图


然后，在OnvifTestTool中会搜索到我的设备


响应Discover Devices的SOAP消息如下：
