1、WS-Discovery的Ad hoc模式，使用多播(不使用gSOAP實現設備發現)
參考文章：ONVIF協議網絡攝像機(IPC)客戶端程序開發(7)：設備搜索

#define COMM_TYPE_MULTICAST 2// 多播
#define COMM_TYPE_BROADCAST 3// 廣播

Linux編譯： gcc search_c.c ， Windows下編譯： gcc search_c.c -lws2_32
Windows下效果和Linux下效果一樣。
我Linux是用的虛擬機，所以需要關閉防火墻，不然搜不到 systemctl stop iptables.service 或 service iptables stop
我們也使用 ONVIF Device Test Tool，測一下
2、使用gSOAP生成ONVIF框架，編寫客戶端
如何生成ONVIF框架參考：ONVIF協議網絡攝像機(IPC)客戶端程序開發(6)：使用gSOAP生成ONVIF框架代碼，原文沒有生成soapServer.c，我在評論里面寫了如何修改，可以參考。
部分文件下載于：GitHub
參考文章：onvif開發之設備發現功能的實現
我做的相關改動都寫在評論區了，server編譯通不過，但client是可行的。
client.c源碼如下：
#include
#include
#include
#include "soapH.h"
#include "soapStub.h"
#include "wsdd.nsmap"
#include "wsaapi.h"
#define MULTICAST_ADDRESS "soap.udp://239.255.255.250:3702"
int main()
{
printf("[%s][%d][%s][%s] start \n", __FILE__, __LINE__, __TIME__, __func__);
int result = 0;
wsdd__ProbeType req;
struct __wsdd__ProbeMatches resp;
wsdd__ScopesType sScope;
struct SOAP_ENV__Header header;
struct soap *soap;
soap = soap_new();
if(NULL == soap )
{
printf("sopa new error\r\n");
return -1;
}
soap->recv_timeout = 10;
soap_set_namespaces(soap, namespaces);
soap_default_SOAP_ENV__Header(soap, &header);
uuid_t uuid;
char guid_string[100];
uuid_generate(uuid);
uuid_unparse(uuid, guid_string);
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 = "dn:NetworkVideoTransmitter";
//"dn:NetworkVideoTransmitter";
int i = 0;
result = soap_send___wsdd__Probe(soap, MULTICAST_ADDRESS, NULL, &req);
while(result == SOAP_OK)
{
result = soap_recv___wsdd__ProbeMatches(soap, &resp);
if(result == SOAP_OK)
{
if(soap->error)
{
printf("soap error 1: %d, %s, %s\n", soap->error, *soap_faultcode(soap), *soap_faultstring(soap));
result = soap->error;
}
else
{
printf("guog *********************************************\r\n");
if(soap->header->wsa__MessageID)
{
printf("MessageID : %s\r\n", soap->header->wsa__MessageID);
}
if(soap->header->wsa__RelatesTo && soap->header->wsa__RelatesTo->__item)
{
printf("RelatesTo : %s\r\n", soap->header->wsa__RelatesTo->__item);
}
if(soap->header->wsa__To)
{
printf("To : %s\r\n", soap->header->wsa__To);
}
if(soap->header->wsa__Action)
{
printf("Action : %s\r\n", soap->header->wsa__Action);
}
for(i = 0; i < resp.wsdd__ProbeMatches->__sizeProbeMatch; i++)
{
printf("__sizeProbeMatch : %d\r\n", resp.wsdd__ProbeMatches->__sizeProbeMatch);
printf("wsa__EndpointReference : %p\r\n", resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference);
printf("Target EP Address : %s\r\n", resp.wsdd__ProbeMatches->ProbeMatch->wsa__EndpointReference.Address);
printf("Target Type : %s\r\n", resp.wsdd__ProbeMatches->ProbeMatch->Types);
printf("Target Service Address : %s\r\n", resp.wsdd__ProbeMatches->ProbeMatch->XAddrs);
printf("Target Metadata Version : %d\r\n", resp.wsdd__ProbeMatches->ProbeMatch->MetadataVersion);
if(resp.wsdd__ProbeMatches->ProbeMatch->Scopes)
{
printf("Target Scopes Address : %s\r\n", resp.wsdd__ProbeMatches->ProbeMatch->Scopes->__item);
}
}
}
}
else if (soap->error)
{
printf("[%d] soap error 2: %d, %s, %s\n", __LINE__, soap->error, *soap_faultcode(soap), *soap_faultstring(soap));
result = soap->error;
}
}
soap_destroy(soap);
soap_end(soap);
soap_free(soap);
printf("[%d] guog discover over !\n", __LINE__);
return result;
}
Linux下編譯： gcc -o client client.c stdsoap2.c soapC.c soapClient.c wsaapi.c duration.c -luuid
沒有libuuid庫，可自行安裝，命令僅供參考 sudo apt-get install uuid-dev
效果如圖：
服務端
1、不使用gSOAP，虛擬機偽裝成ipc

Linux下編譯：gcc ipc_server_c.c -o ipc_server
直接運行
現在我們用 ONVIF Device Test Tool，測試一下
ONVIF Device Test Tool 搜索后，服務端就打印了這些信息
ifconfig查看下虛擬機ip地址
同樣可以被我們之前寫的 客戶端 搜索到
2、使用gSOAP生成ONVIF框架，編寫服務端
文件下載于：GitHub
參考文章：onvif服務器篇之onvif 服務器框架的搭建
碰到的問題同樣寫在評論區，可自行查看。
修改Makefile，GSOAP_ROOT改成自己的soap路徑
終端 make 編譯。生成 deviceserver
我們直接運行 ./deviceserver
我們同樣用 ONVIF Device Test Tool，搜索一下
服務端也有所反應
那么本次的服務端和客戶端都測試完畢了。網上資料不多，真的進行的十分困難。
