Can't open HTTPS URL:s using LUA script

Description:Error opening https URL:s when MQTT HW Device is removed

Hi there. I needed to clean up my installation a bit.

I installed the latest Raspbian Jessie Lite SD card image today followed by installing Domoticz. After that I restored the Domoticz database from a backup.

I have one issue that I can not solve. I had been experimenting with MQTT before and I had a MQTT hardware (MQTT Client Gateway with LAN Inteface) defined. After doing the re-installation I get error messages in the log:

Code: Select all

 Error: MQTT: Failed to start, return code: 14 (Check IP/Port)

So, to get rid of that problem I disabled the MQTT hardware and the error messages disappeared. I don't need MQTT. However when I disable (or remove ) the MQTT Hardware I get a new problem.

Using LUA, commandArray['OpenURL']='http://www.gp.se' works fine but commandArray['OpenURL']='https://www.gp.se' fails with the error: Error: Error opening url: https://www.gp.se

I will be so happy for any kind help to solve this issue. Thanks!

Thats correct, with the new install method, you need to install additional software yourself, like the mosquito mqtt broker

this might work:
apt-get install mosquitto

Thanks @gizmocuz for Your kind help.

Just to be sure, Do I need to install the mosquito mqtt broker even though I don't wish to use MQTT? (I just want to be able to run commandArray['OpenURL'] using https )

Maybe my questions sounds so weird... Yes, I'm still confused about this, I'm sorry for my ignorance.

Is it really necessary to define a "MQTT Client Gateway with LAN interface" hardware and to install mosquitto if I like to use LUA script to open a HTTPS URL using the commandArray (E.g. commandArray['OpenURL']='https://somesite.com')

I think it's a certificate problem. You are trying to set up a secure connection so a valid certificate is expected. If you use a URL with a self-signed certificate its possible it doesn't work.

If you use the os.execute command you would issue a 'curl -k htps://....' command to ignore the SSL certificate.

Thank You.

No, the problem is not the server certificate on the target host.

Summarizing
=================
Issuing the following command from the command line works great:

Code: Select all

curl https://www.google.se

While the following LUA script will fail

Code: Select all

commandArray = {}

if (devicechanged['script_device_test'] == 'On') then
	commandArray['OpenURL']='https://www.google.se/' 
end

return commandArray

From the Domoticz error log:

Code: Select all

Error: Error opening url: https://www.google.se/

And to make everything more obscure... (sorry for that)
-If I create a "MQTT Client Gateway with LAN interface" hardware, the same LUA script above works fine. But I don't want to have a MQTT Client Gateway.

Current workaround solution:
I've made a LUA function used for calling URL:s

Code: Select all

function OpenURL(url)
		if (string.find(url, 'https')) then
			os.execute('curl -s \'' .. url .. '\' > /dev/null 2>&1 &')
		else
			commandArray[#commandArray+1]={['OpenURL']=url }
		end
end
