https request in lua

Question

I am trying to retrieve a page on my SSL enabled server with a lua script. Important to note that the server has a self-signed certificate. No problem with certificate issued by a trusted CA.

local https = require("socket.http")
local resp = {}
local r, c, h, s = https.request{
    url = "https://my-server:443/example.php",
    sink = ltn12.sink.table(resp),
    protocol = "tlsv1"
}

The server returns:

Bad Request Your browser sent a request that this server could not understand. Reason: You're speaking plain HTTP to an SSL-enabled server port. Instead use the HTTPS scheme to access this URL, please.

And on the server side, that request produce this entry in the Apache ssl_access.log

192.168.0.150 - - [27/Nov/2011:16:32:07 +0100] "GET /" 400 529 "-" "-"

Furthermore, tcpdump shows that after the SYN-ACK handshake, no SSL 257 Client Hello is sent. Using the same URL from my browser or with wget works ok.

Answer 1

As Doug Currie said, you should use luasec. In order to enable https.request, you have to require the ssl.https module:

local https = require 'ssl.https'
local r, c, h, s = https.request{
    url = "https://my-server:443/example.php",
    sink = ltn12.sink.table(resp),
    protocol = "tlsv1"
}
