Error when use SSL with self certs

[whitetiger21022014]

Hello I test with RabbitMQ, If I use from file: examples/quick-receive.lua, No SSL, port 1883 everything is Ok, But when I use SSL port, self certs, has problem as below Please correct the 'ssl_params' syntax in below config Thank you so much

Use SSL with self certs

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

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" },
    },
}

Fixed in version v2.0.0
