Error when use SSL with self certs about luamqtt

[whitetiger21022014]

Hello,
In function luasocket_ssl.connect(conn)
if insert for dump conn.ssl_params, I can't see value for custom: cafile, certificate, key
for k, v in pairs(conn.ssl_params) do
print(k,v)
end

When I insert manual for testing as below, it works as expected

conn.ssl_params["cafile"] = "certs/device/cacert.pem"
conn.ssl_params["certificate"] = "/certs/device/clientcert.pem"
conn.ssl_params["key"] = "/certs/device/clientkey.pem"

John,
Thanks for error reporting, will fix it in next release.

According ssl params - you may pass it in ssl = { ... } instead of ssl = true when constructing your MQTT client instance like this:

client = mqtt.client{
	debug = client_debug,
	uri = "x.x.x.x:8883",
	auth = {username = "mqtt_user", password = "123456" },
	clean = true,
	ssl ={	cafile = "/certs/device/cacert.pem",	
			       certificate = "/certs/device/clientcert.pem",
			       key = "/certs/device/clientkey.pem" },
	},
}
