Thanks a lot moreamazingnick, I followed your suggestion and finally I could send post fields correct. Here what I added to original check_curl.php code:
case '-P':
if ($Pocet>$i+1){
parse_str($argv[++$i], $P);
curl_setopt($ch, CURLOPT_POST, count($P));
curl_setopt($ch, CURLOPT_POSTFIELDS,$P);
if ($Debug)echo "\nDEBUG: -P ".$argv[$i];
}else{
echo "ERROR in parsing argument -P: missing value";
Manual();
exit(2);
}
break;
case '-H':
if ($Pocet>$i+1){
curl_setopt($ch, CURLOPT_HEADER, true);
$H=str_getcsv($argv[++$i]);
/* parse_str($argv[++$i], $H);*/
curl_setopt($ch, CURLOPT_HTTPHEADER,$H);
if ($Debug)echo "\nDEBUG: -H ".$argv[$i];
}else{
echo "ERROR in parsing argument -H: missing value";
Manual();
exit(2);
}
break;
I also added the option to send http headers because I need to pass with the posts parameters an API key for authorization.
And this is my Icinga2 command definition
object CheckCommand "check_api_service" {
command = [PluginDir + "/check_curl.php" ]
arguments = {
"-U" = {
value = "$curl_apiURL$"
description = "URL for curl"
}
"-G" = {
value = "$curl_apiGREP$"
description = "GREP for curl"
}
"-P" = {
value = "$curl_apiPOSTF$"
description = "Post fields"
}
"-H" = {
value = "$curl_apiHEADERS$"
description = "Http Headers"
}
}
}
And this is my complete check_curl modified:
