not get block2 option in server

[lx121451]

When I send a Get Message with block2 option，but in server side Options.HasOption(message.Block2) return false。Is there anything that needs special attention？

@jkralik I think this is the relevant code:

https://github.com/plgd-dev/go-coap/blob/49cae1ca2883b97159e646b1d05635ceb1f21bd6/net/blockwise/blockwise.go#L534-L540

Do you recall why the Block2 option is removed from the message before its passed to the next handler function? Maybe the error check is inverted?

@lx121451 Pls, why do you need block2? Thx

No, it's correct.

Just for test，I'm simulating a file transfer server with separate response！

For test you can use https://github.com/plgd-dev/go-coap/blob/master/options/commonOptions.go#L278 to watch all messages that comes to server in v3. I will close the issue, feel free to reopen it.
