FreeSWITCH simple_cdr.lua

FreeSWITCH自带很多cdr模块，有时太多了也不好，搞的不知道怎么选择。我觉得不必纠结，用mod_lua可以很容易，现在就试试

-- apt install -y lua-socket, or yum install -y lua-socket
-- luarun simple_cdr.lua

local url = "http://localhost:8080/cdr"
-- local api = freeswitch.API()
local socket = require "socket"
local http = require("socket.http")
local ltn12 = require("ltn12")

function debug(s)
    freeswitch.consoleLog("DEBUG", s .. "\n")
end

function post_cdr(e)
    http.TIMEOUT = 10
    local response_body = {}
    local headers = {
        ["content-Type"] = "application/json",
        ["content-length"] = #reqbody
    }
    local reqbody = e:serialize("json")
    local r, c, h, s = http.request {
        method = "POST",
        url = url,
        headers = headers,
        source = ltn12.source.string(reqbody),
        sink = ltn12.sink.table(response_body)
    }
    debug("HTTP status-code = " .. c )
    local res = table.concat(response_body)
    debug("response_body = " .. response_body)
end

local con = freeswitch.EventConsumer()
con:bind("SHUTDOWN")
con:bind("CHANNEL_HANGUP_COMPLETE")

while true do
    local e = con:pop()
    if e then
        local event_name = e:getHeader("Event-Name") or ""
        if event_name == "SHUTDOWN" then break
        elseif event_name == "CHANNEL_HANGUP_COMPLETE" then
            post_cdr(e)      
        end
    end
end
