Hello Abhishek,
Thank you for the information about getAllHosts(). I used it along with
setHost() to set the host to coaps in the C++ code.
foo( std::shared_ptr<OC::OCResource> resource )
{
//
// Find the first secure coaps endpoint in the list of hosts. If it's there
// then use it; otherwise use the unsecure coap endpoint.
//
auto resourceHostList = resource->getAllHosts();
for (auto &host : resourceHostList)
{
if (std::string::npos != host.find("coaps://"))
{
resource->setHost(host);
break;
}
}
}
The coaps wasn’t chosen as default host by IoTivity stack for client-side
operations even though secure resources and thus secure endpoints are default
for server-side operations.

Hi,
You can check OC::OCResource:: getAllHosts() API which returns a
vector<std::string> of endpoint strings.
Below is a sample of items inside returned vector for a resource which supports
multiple endpoints :
1. coaps://192.168.1.102:35307
2. coaps://[fe80::ea11:32ff:fe67:7f5d%25p10p1]:46421
3. coaps+tcp://192.168.1.102:40013
4. coaps+tcp://[fe80::ea11:32ff:fe67:7f5d%25p10p1]:44938
One can parse above endpoint strings to know whether endpoint is using CoAP or
CoAPS.
"iotivity\resource\examples\simpleclient.cpp" contains usage example code.
Hope this helps..

It should be added that this appears to only be possible with the C SDK, not
the C++ SDK since the Discovery Callback function signature doesn’t provide
endpoint information.
If the client has to choose which version of a discovered resource to store and
act on (ie. Get/Post) later, there should be a sample app in the C++ SDK that
shows how to do this. We have only found a sample in the C SDK that shows this
and it’s not merged into 1.3-rel or master as of the last time we’ve checked
(last week). This means, no one knows how to perform a Secure Request as a
client unless you’re using the C SDK. This quite odd.
Thanks,
Joey Morrow

Subject: [dev] How to determine if an OC::OCResource object endpoint is using
COAP or COAPS?
Hello,
The code I am working with has a pointer to a C++ OC::OCResource object and I
am trying to determine if the IoTivity endpoint is using COAP or COAPS. The
eps->tps member of the OCResourcePayload data structure can be used to
determine the transport type (i.e., COAP or COAPS). I don't know how to convert
OC::OCResource to type OCResourcePayload so that the connection type can be
determined with the eps->tps member. Is there a way to determine if an
OC::OCResource object is using COAP or COAPS?
