[Freeswitch-users] Execute HTTP request from LUA script not work

[Joel Serrano]

This is a snippet of a LUA script I'm using:

...
require "ltn12"
conn = require "socket.http"
conn.TIMEOUT = 2

function sendRequest()
    local path = "http://example.com/"
    local payload = "SOME_JSON"
    local response_body = { }

    local res, code, response_headers, status = conn.request
    {
        url = path,
        method = "POST",
        headers =
            {
                ["Authorization"] = "Basic SOMETHING",
                ["Content-Type"] = "application/json",
                ["Content-Length"] = payload:len()
            },
        source = ltn12.source.string(payload),
        sink = ltn12.sink.table(response_body)
    }
    session:setVariable("my_http_res, res)
    session:setVariable("my_http_code", code)
    session:setVariable("my_http_status", status)
end

sendRequest()
...



In my case, I have to do a *POST* of an "*application/json*" with *Basic
auth*.

I found this pretty helpful:

lol I also remember going through a headache to get this "simple" thing
working..


Hope it helps!

Joel.
