Hi, John,
Let me share more information about the IoTivity stack & the logic that I'm
using now.
The version of the IoTivity Stack is 1.0 (commit id:
e12c8a3bbdbe28820947d5994f9cf0b76d1f2fe5)
And as I mentioned before, I was using "constructResourceObject" API in
order to communicate with
an resource which is not discoverable. (Registered only with "OC_ACTIVE
flag).
When I insert the host information with "scheme://[address(ipv6)]:port"
format through that API,
I get this error message from the OCResource.cpp (at the end of OCResource
class constructor)
(I've also added "printf" inside the stack so that I could see the actual
string that the stack uses
when checking its length)
=> Error :
terminate called after throwing an instance of 'std::length_error'
what(): host address is too long.
@@@@@@@@@@@@ HOST : coaps://[fe80::a00:27ff:feaf:f911]:50272Aborted
(core dumped) <=== log which "printf" prints..
When I tweaked my pc to use only IPv4 & insert host info. with format like
"coaps://192.168.0.x:xxxx"
into the API "constructResourceObject", it worked fine(meaning, I was able
to communicate with the resource in remote
without resource discovery step).
Again, the stack version is 1.0, not the latest code in the stack.
Would this information helpful enough for you to find the one that you're
looking for?
Please let me know if you need more testing infor. on this issue. :)
One question though, who could provide a patch for this issue(if it's
necessary one.)on IoTivity ver. 1.0 ??
Thank you.
Jay.

Thiago,
The code does indeed pull out the zone ID and zero it before converting so
the length is predictable.
Of course, the zone ID is restored after converting back to binary.

The ZoneID might be added to that, which is one percent sign followed by a
zone ID of platform-specific length limit. On Linux, that's IFNAMESIZ (16
bytes), but on Windows I've seen a full UUID, including the curly braces,
added there.
Unless the ZoneID is removed from the address and placed in a separate
scope ID / interface index variable in the structure. There is such a field
in CAEndpoint_t, so the only question is whether the called properly split
the
address+zoneid and filled in the fields correctly.
