whitespace in hostname render API unable to get labels

[cklagenberg]

Hi

If there is whitespace in "<NAGIOS_DISP_HOSTNAME>" variable in pnp4nagios serivce xml file, I get XML file not found when posting to the labels endpoint.

API endpoints for host and service works.
If the "<NAGIOS_DISP_HOSTNAME>" variable is changed so it fits the "<NAGIOS_HOSTNAME>" variable in the pnp4nagios service XML file it works and I can get a fine graph in Grafana.

Hope it makes sense.

I am not sure that this issue is related to the API controller it self. I don't know PHP but it seems to be the most logical place to start looking for any bugs?
Also, I know whitspace can be a pain, but since it is supported in the Nagios Core I guess it should also be working in pnp4nagios api interface. I can also add that viewing graphs in pnp4nagios works fine with whitespace's in hostnames.

OK example with curl:
LiveU_diskplads.xml:
<NAGIOS_DISP_HOSTNAME>AP3100_LiveU1</NAGIOS_DISP_HOSTNAME>

curl -s -H "Content-Type: application/json" -X POST -d '
{
"host":"AP3100_LiveU1",
"service":"LiveU_diskplads"
}' http://127.0.0.1/pnp4nagios/index.php/api/labels

{"labels":[{"name":"Liveu","label":"disk","service":"LiveU_diskplads","hostname":"AP3100_LiveU1"}]}

BAD example with curl:
LiveU_diskplads.xml:
Fail when <NAGIOS_DISP_HOSTNAME>AP3100 LiveU1</NAGIOS_DISP_HOSTNAME>

curl -s -H "Content-Type: application/json" -X POST -d '
{
"host":"AP3100_LiveU1",
"service":"LiveU_diskplads"
}' http://127.0.0.1/pnp4nagios/index.php/api/labels

{"error":
"XML file "/usr/local/pnp4nagios/var/perfdata/AP3100 LiveU1/LiveU_diskplads.xml" not found.
