onvif实现功能和经验.doc

onvif实现功能:和经验1) 设备匹配probe消息SOAP_FMAC5 int SOAP_FMAC6 soap_serve_dndl_Probe(struct soap *soap).把soap_put_d_ProbeMatchesType(soap, &dn_ProbeResponse, dn:ProbeResponse, NULL) 改成soap_put_d_ProbeMatchesType(soap, &dn_ProbeResponse, d:ProbeMatches, NULL).2) 由analytics.wsdl ptz.wsdl devicemgmt.wsdl media.wsdl event.wsdl 生成头文件,在头文件中要加#import import/wsse.h ,为了实现安全接口3) 安全验证用户SOAP_FMAC3 int SOAP_FMAC4 soap_out_SOAP_ENV_Header(struct soap *soap, const char *tag, int id, const struct SOAP_ENV_Header *a, const char *type).soap-mustUnderstand = 1;if (soap_out_PointerTo_wsse_Security(soap, wsse:Security, -1, &a-wsse_Security, )return soap-error;改为soap-mustUnderstand = 0;if (soap_out_PointerTo_wsse_Security(soap, wsse:Security, -1, &a-wsse_Security, )return soap-error;.4) 生成.c文件D:onvifsoapcpp2 -2 -c -x -L -pws -I D:gsoap-2.8gsoap;d:gsoap-2.8/gsoap/import/ ws.h其中-2参数是选择onvif 1.2 版本, 如果选择-1消息通知就无法被onvif测试工具识别5) 生成.c后缀名的文件全部改成.cpp文件6) onvif要生成客户和服务端, 客户端主要是用来发送hello消息和消息通知接口7) 生成头文件D:onvifwsdl2h.exe c -o ws.h -t typemap.dat -s analytics.wsdl ptz.wsdl devicemgmt.wsdl media.wsdl event.wsdl remotediscovery.wsdl imaging.wsdl要在ws.h文件中增加 #import import/wsse.h 这表明是安全接口8) soapcpp2生成数个.nsmp命名空间文件,只需要用其中一个就可以(我们使用的EventBinding.nsmap)9) 开发人员只需关注wsClient.c, wsServer.c这两个文件,可对他进行修改10) 通过wsdl2h.exe c -o ws.h -t typemap.dat -s analytics.wsdl ptz.wsdl devicemgmt.wsdl media.wsdl event.wsdl remotediscovery.wsdl imaging.wsdl 会报错误,不影响开发.11) 设备发现的soap初试化必为 下列代码soap_init1(&m_soap_entry, SOAP_IO_UDP | SOAP_XML_IGNORENS); struct ip_mreqn imreq; imreq.imr_multiaddr.s_addr =inet_addr(MULTI_GROUPID); imreq.imr_address.s_addr = htonl(INADDR_ANY); imreq.imr_ifindex= 2; m_soap_entry.version = 2; m_soap_entry.send_timeout = 3; / 1s timeout m_soap_entry.recv_timeout = 3; / 1s timeout if (!soap_valid_socket(soap_bind(&m_soap_entry, NULL, 3702, 100) DEBUG_OUTPUT4(CDiscovery:Init soap_valid_socket error); DEBUG_OUTPUT4(CDiscovery:Init soap_valid_socket success); if (setsockopt(m_soap_entry.master, IPPROTO_IP, IP_ADD_MEMBERSHIP, &imreq, sizeof(imreq)error = SOAP_OK; struct sockaddr_in peer; peer.sin_family=AF_INET; peer.sin_port=htons(soap-port); peer.sin_addr.s_addr=inet_addr(soap-host); memcpy(&soap-peer, &peer, sizeof(sockaddr_in); soap-peerlen = sizeof(peer); if(soap_envelope_begin_out(soap) | soap_putheader(soap) | soap_body_begin_out(soap) | soap_put_dnrd_Hello(soap, &soap_tmp_dnrd_Hello, -dnrd:Hello, NULL) | soap_body_end_out(soap) | soap_envelope_end_out(soap) | soap_end_send(soap) return soap_closesock(soap);13) 开发人员要实现服务端所有接口,下面是部分接口(请参考wsClient.cpp 文件SOAP_FMAC5 int SOAP_FMAC6 _dndl_Probe(struct soap*, struct d_ProbeType *dn_Probe, struct d_ProbeMatchesType *dn_ProbeResponse);SOAP_FMAC5 int SOAP_FMAC6 _dnrd_Hello(struct soap*, struct d_HelloType *dn_Hello, struct d_ResolveType *dn_HelloResponse);SOAP_FMAC5 int SOAP_FMAC6 _dnrd_Bye(struct soap*, struct d_ByeType *dn_Bye, struct d_ResolveType *dn_ByeResponse); 14) 安全用户名和密码是采用openssl库和gsoap的自带的控件, 采用下列接口soap_wsse_verify_Passwordsoap_wsse_verify_Timestampsoap_wsse_get_Username15) openssl 编译tar zxvf openssl-0.9.8.tar.gzcd openssl-0.9.8./config no-asm -prefix=/opt/openssl os/compiler: /ToolChain/bin/arm-none-linux-gnueabi-g+makemake install 之后进入到/opt/openssl 拷贝头文件和库16) 通过80端口发送流首先要判断消息是onvif消息还是请求流消息, 通过MSG_PEEK来区分如果是onvif消息就走onvi
