[Freeswitch-users] CURL from Lua Script

[Don Hawkins]

So anytime I try to get a variable like UUID I always get  "attempt to call
method 'getVariable' (a nil value)". It's calling the test.lua script at
the right time but I've been unable to access a single variable so far. The
phone is literally ringing at the time the script is called so I'm sure
there is a session.

test.lua looks like this (line 3 is the problem and line 2 has no value).

api = freeswitch.API();
local uuidto = event:getHeader("Unique-ID")
local uuid session:getVariable("uuid")
post_response = api:execute("curl", "
http://voiceapi.cloud/API/callflow/test3.php?event=ringing&uuid=..
uuidto ..")
