Sendtohttp command not working from rules. Works from command line. #4

I use sendtohttp commands to start and stop video recording with Raspberry Pi cameras. Using a PIR sensor and when pir is triggered the rules sends the command. The log shows that the pir event sends the sentohttp event but the camera does not seem to get the message. From the tools page using the command line box it does work sending the exact same command manually.

This is the rule....

on pir#switch do if [pir#switch]=1
sendtohttp 192.168.1.103,80,/cam/cmd_pipe.php?cmd=ca%201 timerSet 1,15 endon on Rules#Timer=1 do sendtohttp 192.168.1.103,80,/cam/cmd_pipe.php?cmd=ca%200 endon

This is the web log output.....

22:28:34 CMD: sendtohttp 192.168.1.103,80,/cam/cmd_pipe.php?cmd==ca%201 22:28:34 CMD: timerSet 1,15 22:28:37 Event: si7021#temp=76.3 22:28:37 Event: si7021#humid=19.8 22:28:43 Event: pir#switch=0.0 22:28:49 Event: Rules#Timer=1 22:28:49 CMD: sendtohttp 192.168.1.103,80,/cam/cmd_pipe.php?cmd==ca%200 22:29:00 Event: Clock#Time=Mon,22:29

Camera should record a 15 second video. It does not. Exact same command works from the tools command box. Camera records video. Please let me know if you need more info.

I guess that the "=" sign processed as a condition and replaced with "==" to pass it to the python interpreter. Could you try that what the camera outputs when you write a browser to this: http://192.168.1.103:80/cam/cmd_pipe.php?cmd==ca%200

I think now it is working as expected, please try it.

I did a git pull to update. Restarted the PI. Changed the rull command to 2 == instead of 1 Same results I'm afraid. :(

Still works from command box Still NOT from rules. Sorry...

Command box calling the same sendto function as from the rules. Please do not use two == in rules, test it in your browser directly, if it is working with the camera.

  1. I've made a /cam/cmd_pipe.php file on my webserver for testing, which has only one function: when called it saves its "cmd" parameter to a text file on the server with a timestamp.
  2. I made the following rules 
    on test do
sendtohttp 192.168.2.100,80,/cam/cmd_pipe.php?cmd=ca%200
endon

    when i called "event,test" from RPIEasy than "ca 0" value arrived on the text file on the server, as expected. At this point i have to say that i am unable to reproduce this error.

In case you want to do some testing, the PHP code i used is the following: (be sure to add rights for creating test.txt or the file never appears)

<!DOCTYPE html><html lang='hu'><head>
<meta http-equiv='Content-Type' content='text/html; charset=utf-8'>
<?php
 $file = 'test.txt';
 $cmdnum = $_REQUEST['cmd'];
 $tstr = date("H:i:s").' incoming "cmd" value='.$cmdnum;
 echo $tstr;
 file_put_contents($file, $tstr);
?></script></body></html>

Working now. Was probably working after your update as I was missing the comma after the port number in the url. Sorry about that....
