生成ONVIF的框架代码

可以参考这章海思[Hi3531]onvif协议实现基于gsoap和openssl
只是实现IP自动搜索还要添加一个remotediscovery.wsdl文件去生成onvif框架代码

附上关键代码

自动搜索IP

1. 主要代码

 soap_init(&soap);
	char Mediaddr[256] = "";
	char profile[256] = "";
	char ip[128] = "";
	HI_S32 i,j;
	HI_S32 client_port,client_port2;
	struct _tds__GetCapabilities				req;
	struct _tds__GetCapabilitiesResponse		rep;
	struct wsdd__ProbeType wreq;
    struct __wsdd__ProbeMatches wresp;
    struct wsdd__ScopesType sScope;
    struct SOAP_ENV__Header header;
	
	char guid_string[100];
	soap.recv_timeout = 5;
	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;
    //先填充头部，一般按我这个填就好

	soap_default_wsdd__ScopesType(&soap, &sScope);
    sScope.__item = "";
    soap_default_wsdd__ProbeType(&soap, &req);
    wreq.Scopes = &sScope;
    wreq.Types = "";
	
	
	result = soap_send___wsdd__Probe(&soap, "soap.udp://239.255.255.250:3702", NULL, &req);
	do{
    
     result = soap_recv___wsdd__ProbeMatches(&soap, &wresp); 
     if (soap.error) 
     {
     
         printf("soap error:%d---%s",soap.error,*soap_faultstring(&soap)); 
         result = soap.error; 
         break;
     } 
     else
     {
    
        printf("wsdd:UriListType:%s\n",wresp.wsdd__ProbeMatches->ProbeMatch->XAddrs);
		HI_S8 * camera_ip = wresp.wsdd__ProbeMatches->ProbeMatch->XAddrs + 7;
		//地址偏移获取ip地址的起始地址
		camera_ip = strtok(camera_ip,"/");
		//分割字符串返回准确ip地址
		printf("ID-%d ip:%s\n",*vdec_num,camera_ip);
		strcpy(stVdecSend[*vdec_num].ip,camera_ip);
		//printf("-----------%d----------\n",__LINE__);
		if(strstr(wresp.wsdd__ProbeMatches->ProbeMatch->Scopes->__item,"Dahua"))
		{
    
			//这里是判断摄像头的厂家是大华还是海康威视
			strcpy(stVdecSend[*vdec_num].company,"Dahua");
		}
		else if(strstr(wresp.wsdd__ProbeMatches->ProbeMatch->Scopes->__item,"HIKVISION"))
		{
    
			strcpy(stVdecSend[*vdec_num].company,"HIKVISION");
		}
		//printf("-----------%d----------\n",__LINE__);
		printf("----------ip:%s,company:%s------------\n",stVdecSend[*vdec_num].ip,stVdecSend[*vdec_num].company);
		(*vdec_num)++;
     }
 }while(1);

 	soap_destroy(&soap); // clean up class instances
	soap_end(&soap); // clean up everything and close socket, // userid and passwd were deallocated
	soap_done(&soap); // close master socket and detach context

PTZ的实现

1. 获取摄像头PTZ功能的操作地址

//这个是设备地址，通过它可以获得ptz和imaging的操作地址
sprintf(endpoint, "http://%s/onvif/device_service", pstVdecSend->ip);
//获取PTZ操作地址
soap_call___tds__GetCapabilities(&soap, endpoint, NULL, &req, &rep);
//req和rep分别是发送结构体，和接受结构体
if (soap.error)
{
    
	printf("[%s][%d]--->>> soap result: %d, %s, %s\n", __func__, __LINE__,
		soap.error, *soap_faultcode(&soap),
		*soap_faultstring(&soap));
}
else
{
    
	printf("get capability success\n");
	printf("PTZ_XAddr====%s\n",rep.Capabilities->PTZ->XAddr);
	//获取成功在这里会成功返回
	strcpy(PTZaddr, rep.Capabilities->PTZ->XAddr);
}

2. 申请鉴权并获取配置文件

soap_wsse_add_UsernameTokenDigest(&soap, NULL, "admin", "jjoe0308");
//申请鉴权输入账号和密码
	if (soap_call___ns1__GetProfiles(&soap, Mediaddr, NULL, &getProfiles, &getProfiles_response) == SOAP_OK)
	{
    
		printf("get profile succeed \n");
		printf("profile:%s\n",getProfiles_response.Profiles[0].token);
		strcpy(profile, getProfiles_response.Profiles[0].token);
		//在返回的接受的结构体中去获取配置文件
	}
	else
	{
    
		printf("get profile failed \n");
		printf("[%s][%d]--->>> soap result: %d, %s, %s\n", __func__, __LINE__,
			soap.error, *soap_faultcode(&soap),
			*soap_faultstring(&soap));
	}

3. 填充参数配置摄像头

tptz__RelativeMove.ProfileToken = profile;
//填充配置文件
tptz__RelativeMove.Translation->PanTilt->space = NULL;
tptz__RelativeMove.Translation->Zoom->space = NULL;
tptz__RelativeMove.Speed->PanTilt->space = NULL;
tptz__RelativeMove.Speed->Zoom->space = NULL;
//这四个一般为NULL
tptz__RelativeMove.Speed->PanTilt->x = 1;
tptz__RelativeMove.Speed->PanTilt->y = 1;
tptz__RelativeMove.Speed->Zoom->x = 1;
//上面给x,y,z的速度进行赋值，范围为0~1
tptz__RelativeMove.Translation=(struct tt__PTZVector*)soap_malloc(&soap,sizeof(struct tt__PTZVector));
tptz__RelativeMove.Translation->PanTilt = (struct tt__Vector2D*)soap_malloc(&soap,sizeof(struct tt__Vector2D));
tptz__RelativeMove.Translation->Zoom = (struct tt__Vector1D*)soap_malloc(&soap,sizeof(struct tt__Vector1D));
tptz__RelativeMove.Speed = (struct tt__PTZSpeed*)soap_malloc(&soap,sizeof(struct tt__PTZSpeed));
tptz__RelativeMove.Speed->PanTilt = (struct tt__Vector2D*)soap_malloc(&soap,sizeof(struct tt__Vector2D));
tptz__RelativeMove.Speed->Zoom = (struct tt__Vector1D*)soap_malloc(&soap,sizeof(struct tt__Vector1D));

//在这里我举个例子，设置x旋转（范围好像是-1~1）
//y是上下旋转，Z是焦距
tptz__RelativeMove.Translation->PanTilt->x = 1;
tptz__RelativeMove.Translation->PanTilt->y = 0;
tptz__RelativeMove.Translation->Zoom->x = 0;

//先鉴权，然后通过接口soap_call___tptz__RelativeMove设置摄像头参数，这个接口是相对运动接口，当然也有绝对运动和方向运动等等
soap_wsse_add_UsernameTokenDigest(&soap, NULL, "admin", "jjoe0308");
if (soap_call___tptz__RelativeMove(&soap, PTZaddr, NULL, &tptz__RelativeMove, &tptz__RelativeMoveResponse) == SOAP_OK)
{
    
	printf("set ptz succeed \n");
	printf("profile====%s\n", profile);
}
else
{
    
	printf("get profile failed \n");
	printf("[%s][%d]--->>> soap result: %d, %s, %s\n", __func__, __LINE__,
		soap.error, *soap_faultcode(&soap),
		*soap_faultstring(&soap));
}	
//没有报错，成功运行一般就设置成功啦
