Hi Mario,
Thank you once more for your help!
Taking a lot of time to assemble the corrects parts, here is my openHab3 ECMA function I use to call URL if it can help some of us.
var logger = Java.type('org.slf4j.LoggerFactory').getLogger('org.openhab.rule.' + ctx.ruleUID); var url = itemRegistry.getItem('http_get_command').state + ""; if(!!url){ var HTTP = Java.type("org.openhab.core.model.script.actions.HTTP"); var headers = []; if(url.startsWith("http://kitchen")){ headers["Authorization"] = "Basic dXNlcjpwYXNzd29yZA=="; logger.info("adding headers for kitchen"); }else if (url.startsWith("http://room2 headers["Authorization"] = "Basic dXNlcjpwYXNzd29yZA=="; logger.info("adding headers for room2"); } var result = HTTP.sendHttpGetRequest(url, headers, 15*1000); if(result == null){ logger.info("result: ERROR"); } else { logger.info("result: OK"); } } else{ logger.warn("Ooops url is empty"); }This function is used as a trigger of a String value model nammed „http_get_command“.
The habPannel button panel send commands to this model value. The command contains the full URL.
As my players are password protected, you’ll need to adapt this with your user:password encoded in base 64. You can compute it in a terminal
echo -n user:password | base64this example should output „dXNlcjpwYXNzd29yZA==“
Make the same with your real user:password and replace „dXNlcjpwYXNzd29yZA==“ in the code with it for each player.
I know it’s not really safe to stock this as clear text password in a script file…
I hope it’ll help.
Hi Mario!
Thank you very much for your Help !
I’v managed that tonight!
If it can help someone :
I’ve had to create a shell script that I’ll name runTelnetCommand.sh
#!/bin/bash if [ $1 == "connect" ] then echo "Send to $4:9090 to connect Player $2 on server $3" printf "$2 connect $3\nexit\n" | nc $4 9090 2>/dev/null | cut "-d " -f 3 echo "Done" else echo "Unknown command $1" fiI’ve put this script on my openHab volume on path /openhab/userdata/etc/scripts/runTelnetCommand.sh (i’m using a dockerized openhab)
You just have to put this script somewhere openHab can access it.Check it’s runnable with
chmod +x /openhab/userdata/etc/scripts/runTelnetCommand.shOn my docker container I’ve had to install nc which is not packaged
Connect manually to the container :
docker exec -it <containerId> /bin/bash
Install netCat to send telnet commands
apt-get update && apt-get install -y netcatWithin my ECMA javascript action for my openHab trigger script I’ve add a exec
var logger = Java.type('org.slf4j.LoggerFactory').getLogger('org.openhab.rule.' + ctx.ruleUID); var Exec = Java.type("org.openhab.core.model.script.actions.Exec"); var Duration = Java.type("java.time.Duration"); var serverScriptPath = '/openhab/userdata/etc/scripts/runTelnetCommand.sh'; var serverScriptCommand = 'connect'; var mac_room1 = 'aa:bb:cc:dd:ee:ff'; var mac_room2 = 'ff:ee:dd:cc:bb:aa'; var firstServerIp = '192.168.1.15'; var secondServerIp = '192.168.1.16'; logger.info("Result connection room1: " + Exec.executeCommandLine(Duration.ofSeconds(20), serverScriptPath, serverScriptCommand, mac_room1, firstServerIp, secondServerIp)); logger.info("Result connection room2: " + Exec.executeCommandLine(Duration.ofSeconds(20), serverScriptPath, serverScriptCommand, mac_room2, firstServerIp, secondServerIp));It’s important to send commands to IP’s because DNS names does not seems to work.
Having those function I can switch players mac_room1 and mac_room2 from server 1 to server 2
I hope this will help 😉
