openURL error

[Maxx]

Hi,

Since the update to the latest Beta (4.11415 ) I am getting error messages with the openURL call. I made a test script:

Code: Select all

return {
	on = {
		timer = {'every minute'},

	},
	execute = function(dz, triggeredItem)
	        local string = 'http://192.168.1.231:8080//json.htm?type=command&param=udevice&idx=2001&nvalue=0&svalue=12'
	        dz.log(string)
            dz.openURL({
            url = string,
         })
	end
}

it gives the following error:

Code: Select all

2019-11-02 13:54:00.895 Error: Error opening url: http://192.168.1.231:8080//json.htm?type=command&param=udevice&idx=2001&nvalue=0&svalue=12

it worked without problem before the update.

Did something change with the LUA update?

Hi,

Since the update to the latest Beta (4.11415 ) I am getting error messages with the openURL call.

Can you try again but with only one / before the JSON ?

Same error:

I checked this url with domoticz 4.11434 (dzVents 2.5.0) and domoticz 4.11454 (dzVents 2.5.0) but do not see any unexpected behavior
What do you see in the log if you execute this test script ?

Code: Select all

return {
	on = {
		timer = {'every minute'},
		httpResponses = { 'testUrl*' },
	},
	execute = function(dz, item)
		if item.isHTTPResponse then
			dz.utils.dumpTable(item)
			dz.log('Domoticz and dzVents version: ' .. dz.settings.domoticzVersion .. ', ' .. dz.settings.dzVentsVersion,dz.LOG_FORCE)
		else
		    urls =
			{ 	
				["testUrl1"] = 'http://192.168.1.231:8080//json.htm?type=command&param=udevice&idx=109&nvalue=0&svalue=12',
				["testUrl2"] = 'http://192.168.1.231:8080/json.htm?type=command&param=udevice&idx=109&nvalue=0&svalue=12', 
				["testUrl3"] = dz.settings['Domoticz url'] .. '//json.htm?type=command&param=udevice&idx=109&nvalue=0&svalue=12' ,
				["testUrl4"] = dz.settings['Domoticz url'] .. '/json.htm?type=command&param=udevice&idx=109&nvalue=0&svalue=12' ,
			}

			for callback, url in pairs(urls) do 
				dz.openURL({ url = url , callback = callback })
			end
		end
	end
}

Here the log
I changed the device in 2001, wich is an existing device (Dummy custom sensor)

Something else, maybe related, I am using a second domoticz server and I use remote server to share variables. This works fine except with dummy devices. They do not appear in the main device list, all the others do.

The URL call in this case is also to a dummy device..

Hi Waaren,

This line works:

Code: Select all

["testUrl4"] = dz.settings['Domoticz url'] .. '/json.htm?type=command&param=udevice&idx=2001&nvalue=0&svalue=22'

the others give an error:

Here the log
I changed the device in 2001, which is an existing device (Dummy custom sensor)

Something else, maybe related, I am using a second domoticz server and I use remote server to share variables. This works fine except with dummy devices. They do not appear in the main device list, all the others do.

The URL call in this case is also to a dummy device..

What I see in the log is that the only testURL working is testUrl4. That url is targeted at the local system.
Is http://192.168.1.231 the same system ?

[Maxx]

It is the same system.

I was thinking it may have something to do with authentication so I add the username and password but it still give an error

It is the same system.

can you try below test script after adding 192.168.1.* to the field [ Local Networks (no username/password):] in [system] [setup] [settings]
so that it look something like: 127.0.0.1;192.168.1.*

Code: Select all

return {
	on = {
		timer = {'every minute'},
		httpResponses = { 'testUrl*' },
	},
	execute = function(dz, item)
		if item.isHTTPResponse then
			dz.utils.dumpTable(item)
			dz.log('Domoticz and dzVents version: ' .. dz.settings.domoticzVersion .. ', ' .. dz.settings.dzVentsVersion,dz.LOG_FORCE)
			dz.log('Domoticz url: ' .. dz.settings['Domoticz url'],dz.LOG_FORCE)
		else
		    urls =

Spot on, like magic. Works like a charm

What is the story behind this?

Spot on, like magic. Works like a charm

What is the story behind this?

By adding the 192.168.1.* you allow all systems from your home network to access domoticz API without a username / password.
Can only tell what the problem was if I know what was in this field before and what the content of your /etc/hosts is .

[Maxx]

/etc/hosts content:

Code: Select all

127.0.0.1	localhost
::1		localhost ip6-localhost ip6-loopback
ff02::1		ip6-allnodes
ff02::2		ip6-allrouters

127.0.1.1	raspberrypi

127.0.0.1 was in the field

[waaren]

127.0.0.1 was in the field

And what was the logline produced by

Code: Select all

dz.log('Domoticz url: ' .. dz.settings['Domoticz url'],dz.LOG_FORCE)

?

[Maxx]

2019-11-03 17:22:01.156 Status: dzVents: !Info: Domoticz url: http://127.0.0.1:8080

[waaren]

2019-11-03 17:22:01.156 Status: dzVents: !Info: Domoticz url: http://127.0.0.1:8080

Only things I can think of why it works now and did not do previously is a funny character in the field. 127.0.0.1
or 127.0.1.1 in the /etc/hosts for raspberrypi.
I have this in my /etc/hosts where PI-2 is my 'production' domoticz and PI-6 is test

Code: Select all

127.0.0.1       localhost
::1             localhost ip6-localhost ip6-loopback
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

192.168.192.59          PI-2
192.168.192.109         PI-6
192.168.192.1           R7800

[Maxx]

Well, thanks for your time again.

I will have a closer look at the host file options, it looks interesting since I have a production and a test domoticz too

I have a similar problem as mentioned in https://www.domoticz.com/forum/viewtopi ... 59&t=24453, my script is below:

looks like you are not authorized.
What do you see when sending the same using curl ?

[cjb75]

I think I'm authorized since

if (item.isHTTPResponse and item.ok) then

and

if (item.trigger == 'unifi_loggedin') then

seems to be true.

See code below:

Code: Select all

if (item.isTimer or item.isDevice) then
             dz.openURL({
                 url = controllerUrl .. 'api/login',
                 method = 'POST',
                 postData = {
                     ['password'] = controllerPassword,
                     ['username'] = controllerLogin
                 },
                 callback = 'unifi_loggedin'
             })
         end
 
         if (item.isHTTPResponse and item.ok) then
             if (item.trigger == 'unifi_loggedin') then
                 dz.utils.dumpTable(item)
                 dz.log('Domoticz and dzVents version: ' .. dz.settings.domoticzVersion .. ', ' .. dz.        settings.dzVentsVersion,dz.LOG_FORCE)
 
                 dz.log('Domoticz url: ' .. dz.settings['Domoticz url'],dz.LOG_FORCE)
                 dz.openURL({
                     url = controllerUrl .. 'api/s/default/stat/sta',
                     method = 'GET',
                     callback = 'unifi_data'
                 })

I'm not sure how to use curl but using the command:

curl --cookie /tmp/unifi_cookie --cookie-jar /tmp/unifi_cookie --insecure -X POST -d '{"password":"mypassword","username":"domoticz"}' https://192.168.0.2:8443/api/login

followed by:

curl --cookie /tmp/unifi_cookie --cookie-jar /tmp/unifi_cookie --insecure --data "json={}" https://192.168.0.2:8443/api/s/default/stat/sta

works for me

seems to be true.

You are authorized to send the first one but the error you see is the return of the seconds openURL. I never managed to send something to a URL where a cookie is required from domoticz using dz.openURL
Probably the quickest way to success here is to use os.execute(cmd) with the curl as cmd.
