ONVIF学习之实现discovery

ONVIF实现的第一步当然是discovery，但是实现discovery分为被发现和主动发现。

实现被发现，我参考的博客是，很完整，根据这个就可以实现。

实现主动发现，代码如下：

#include "soapH.h"  
#include "wsdd.nsmap"  

#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h>
#include <sys/types.h>

#include <netinet/in.h>

#define __DEBUG
#ifdef __DEBUG
#define DBG(fmt,args...) fprintf(stdout,  fmt,  ##args)
#else
#define DBG(fmt,args...)
#endif
#define ERR(fmt,args...) fprintf(stderr,  fmt,  ##args)


#define set_block_fd(fd)    fcntl(fd, F_SETFL, 0)
#define set_nonblock_fd(fd) fcntl(fd, F_SETFL, NOBLOCK)

//char *server_ip="49.123.73.192";

#define SMALL_INFO_LENGTH 20
#define IP_LENGTH 20
#define INFO_LENGTH 100

int main(int argc, char **argv)
{
	struct soap *soap;
    struct wsdd__ProbeType req;
    struct __wsdd__ProbeMatches resp;
    struct wsdd__ScopesType sScope;
    struct SOAP_ENV__Header header;
    int count = 0;
    int result = 0; 
 
    char guid_string[100];
 
     soap = soap_new(); 
    if(soap==NULL)
    {
        return -1;
    }
  
    soap_set_namespaces(soap, namespaces); 
 
    //soap->recv_timeout = 5;      //超过5秒钟没有数据就退出
    soap_default_SOAP_ENV__Header(soap, &header);
  
    header.wsa__MessageID = guid_string;
    header.wsa__To= "urn:schemas-xmlsoap-org:ws:2005:04:discovery";
    header.wsa__Action= "http://schemas.xmlsoap.org/ws/2005/04/discovery/Probe";
    soap->header = &header;
 
    soap_default_wsdd__ScopesType(soap, &sScope);
    sScope.__item = "";
    soap_default_wsdd__ProbeType(soap, &req);
    req.Scopes = &sScope;
    req.Types = "";
 
    result = soap_send___wsdd__Probe(soap, "soap.udp://239.255.255.250:3702", NULL, &req);

	do{
         result = soap_recv___wsdd__ProbeMatches(soap, &resp); 
         if (soap->error) 
         { 
		printf("soap error!\n");
             	result = soap->error; 
             	break;
         } 
         else
         {
            
		printf("=================================\n");
            printf("%d\n",resp.wsdd__ProbeMatches->__sizeProbeMatch);
            printf("%d\n",resp.wsdd__ProbeMatches->ProbeMatch->MetadataVersion);
            printf("%s\n",resp.wsdd__ProbeMatches->ProbeMatch->Scopes->__item);
            printf("QName:%s\n",resp.wsdd__ProbeMatches->ProbeMatch->Types);
            printf("xsd:string:%s\n",resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.Address);
            //printf("xsd:QName:%s\n",resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.PortType);
            //printf("wsa:ServiceNameType:%s\n"resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.ServiceName);
            //printf("sequence of elements:%s\n",resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.__size);
            printf("xsd:anyType:%s\n",resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.__anyAttribute);
            //printf("endpoint any:%s\n",resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.__any);
            printf("wsdd:UriListType:%s\n",resp.wsdd__ProbeMatches->ProbeMatch->XAddrs);
		printf("============================\n");
         }
     }while(1);
 
    soap_destroy(soap); 
    soap_end(soap);      
    soap_done(soap);
 
    return result;
}

通过这个代码发现了大华的摄像头，我把完整的工程也传上来了，供大家参考。
