如何解决如何通过gsoap实现onvif CreatePullPointSubscription操作
请参考onvif核心规范:如果订阅被接受,则响应中包含对以下内容的WS-EndpointReference: 实例化拉点。该WS-Endpoint提供了PullMessages操作,该操作是 客户端用来检索通知。
但是我看不到关于实例化拉点的代码,而且我也不知道如何实现它。这是我的编码。
SOAP_FMAC5 int SOAP_FMAC6 __tev__CreatePullPointSubscription(struct soaP* soap,struct _tev__CreatePullPointSubscription *tev__CreatePullPointSubscription,struct _tev__CreatePullPointSubscriptionResponse *tev__CreatePullPointSubscriptionResponse)
{
tev__CreatePullPointSubscriptionResponse->SubscriptionReference.Address = (char *)soap_malloc(soap,sizeof(char) * 128);
strcpy(tev__CreatePullPointSubscriptionResponse->SubscriptionReference.Address,"http://192.168.12.1/Subscription?Idx=0");
tev__CreatePullPointSubscriptionResponse->wsnt__CurrentTime=time(NULL);
tev__CreatePullPointSubscriptionResponse->wsnt__TerminationTime=tev__CreatePullPointSubscriptionResponse->wsnt__CurrentTime+60;
return SOAP_OK;
}
有人能照亮我吗?预先谢谢你。
解决方法
void CreatePullPointSubscription() {
struct soap *m_soap = soap_new();
m_soap->connect_timeout = SOAP_REQUEST_TIMEOUT_IN_SECONDS;
m_soap->recv_timeout = SOAP_REQUEST_TIMEOUT_IN_SECONDS;
m_soap->send_timeout = SOAP_REQUEST_TIMEOUT_IN_SECONDS;
PullPointSubscriptionBindingProxy subscriptionProxy(m_soap);
subscriptionProxy.soap_endpoint = xAddr;
if (addCredentialsToCall(m_soap)) {
_tev__CreatePullPointSubscription request;
_tev__CreatePullPointSubscriptionResponse response;
auto ret = subscriptionProxy.CreatePullPointSubscription(&request,response);
if (ret != SOAP_OK) {
soap_stream_fault(m_soap,std::cerr);
} else {
auto address = response.SubscriptionReference.Address;
std::cout << address << std::endl;
std::cout << "Subscription metadata: " << response.SubscriptionReference.Metadata << std::endl;
std::cout << "Termination time " << response.wsnt__TerminationTime << std::endl;
std::cout << "Current time " << response.wsnt__CurrentTime << std::endl;
std::string uuid = std::string(soap_rand_uuid(m_soap,"urn:uuid:"));
struct SOAP_ENV__Header header;
header.wsa5__MessageID = (char *) uuid.c_str();
header.wsa5__To = response.SubscriptionReference.Address;
m_soap->header = &header;
if (addCredentialsToCall(m_soap)) {
_tev__PullMessages tev__PullMessages;
tev__PullMessages.Timeout = "PT600S";
tev__PullMessages.MessageLimit = 100;
_tev__PullMessagesResponse tev__PullMessagesResponse;
auto ret = subscriptionProxy.PullMessages(&tev__PullMessages,tev__PullMessagesResponse);
for (auto msg : tev__PullMessagesResponse.wsnt__NotificationMessage) {
std::cout << "\tMessage is :" << msg->Topic->__mixed << std::endl;
}
} else {
std::cout << "Couldn't set credentials!!!" << std::endl;
}
}
}
subscriptionProxy.destroy();
}
This worked for me atleast to pull the event initializers.
