Curl isn't woking with Nagios - php

Question

I'm currently developing a nagios plugin with PHP and cURL.
My problem is that my script is working well when i use it with PHP like this :
#php /usr/local/nagios/plugins/script.php
I mean it returns me a 200 HTTP CODE.
But with nagios it returns me a 0 HTTP CODE. It's strange because the php is working with NAGIOS (i can read variables...). So the problem is that Nagios can't use cURL.
Can someone give me a clue ? Thanks.
Here you can see my code.
<?php
$widgeturl = "http://google.com";
$agent = "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.12) Gecko/2009070611 Firefox/3.0.12";
if (!function_exists("curl_init")) die("pushMeTo needs CURL module, please install CURL on your php.");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $widgeturl);
$page = curl_exec($ch); //or die("Curl exe failed");
$code=curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($code==200) {
fwrite(STDOUT, $page.'Working well : '.$code);
exit(0);
}
else {
fwrite(STDOUT, $page.'not working : '.$code);
exit(1);
}
curl_close($ch);
Solution :
It was because the proxy was basically set on my OS (centOS), but Nagios was not using it instead of PHP. So i just had to put : curl_setopt($ch, CURLOPT_PROXY, 'myproxy:8080'); curl_setopt($ch, CURLOPT_PROXYUSERPWD, "user:pass"); Hope it could help someone

Answer 1

curl_setopt($ch, CURLOPT_PROXY, 'myproxy:8080');
curl_setopt($ch, CURLOPT_PROXYUSERPWD, "user:pass")

Answer 2

Can you try making the CURL request like this (i.e. header only request):
<?php
// config
$url = 'http://www.google.com/';
// make request & parse response
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_FILETIME, true);
curl_setopt($curl, CURLOPT_NOBODY, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$response_header = curl_exec($curl);
$response_info = curl_getinfo($curl);
curl_close($curl);
// debug
echo "<b>response_header</b>\r\n";
var_dump($response_header);
echo "<b>response_info</b>\r\n";
var_dump($response_info);
The above will output the following:
