How to get Peer IP Address in Nitrogen
Is is there a built in function in nitrogen framework to get P开发者_如何学Ceer IP address? If not, is there a way to get the IP address of peer which is making to request to Nitrogen App
You can get the remote peer's address using wf_platform:get_peername/0
.
@spec wf_platform:get_peername() -> {ok, {Address, Port}} | {error, posix()}
Address = {N1,N2,N3,N4} | {K1,K2,K3,K4,K5,K6,K7,K8}
Port = int()
As of Nitrogen2, the function to do this is wf:peer_ip/0
. It doesn't seem to appear in any docs at the moment, but it does almost the same thing wf_platform:get_peername()
used to.
wf:peer_ip/0 -> {A, B, C, D} | {A, B, C, D, E, F, G, H}
%% example output: {127, 0, 0, 1}
