ONVIF 设备发现 VC++实现
设备发现的过程：客户端发送报文到239.255.255.250的3702端口(ONVIF协议规定)，服务器收到报文后再向客户端返回一个报文，客户端收到这个报文然后解析出Xaddrs，这就完成了一次设备发现。请看下面代码:
// 正在表达式
std::string ippattren = ("\\d+\.\\d+\.\\d+\.\\d+(\:\\d+|\.{5})");
std::string brand = ("\/name\/(\.\*)\\s");
std::string model = ("\/hardware\/(\.\*)\\s");
std::string stType = ("\/type\/(\.\*)\\s");
// 忽略大小写
std::regex_constants::syntax_option_type fl = std::regex_constants::icase;
// 编译正在表达式
std::regex regExpress(ippattren, fl);
std::regex regBrand(brand,fl);
std::regex regModel(model,fl);
std::regex regType(stType,fl);
std::smatch ms;
char *pBuffer;
//UUID 好最后是变化的否则 onvif 组播服务可能只回复一次
std::string guid_string = "uuid:68749E8A-2EDD-49C0-ABF8-45E0733911BF";
wsddProxy discovery;
//获取guid(windows下叫guid，linux下叫uuid)，格式为urn:uuid:8-4-4-4-12，由系统随机产生
static char buf[64] = {0};
GUID guid;
if (S_OK == ::CoCreateGuid(&guid))
{
//如果guid生成成功，则将其转为字符串，保存在buf中
_snprintf_s(buf, sizeof(buf)
, "uuid:%08X-%04X-%04x-%02X%02X-%02X%02X%02X%02X%02X%02X"

, guid.Data4[2], guid.Data4[3], guid.Data4[4], guid.Data4[5]
, guid.Data4[6], guid.Data4[7]
);
guid_string = buf;
}
//超过5秒没有数据就退出
