request = function()
wrk.method = "POST"
wrk.headers["Content-Type"] = "application/json"
wrk.headers["authorization"] = "Bearer ".."your.access.token"
local tid = wrk.thread:get("id")
-- generate random id
local orderId = "wrk"..os.time()..string.sub(math.random(),10)..tid
--print(orderId)
wrk.body = string.format(bodyTemp, orderId)
return wrk.format(nil)
end
function response(status, headers, body)
print(status)
