Title: PHP check server status (online offline)
Post by: TAiS46 on October 17, 2012, 07:43:18 PM

Hey,

I am trying to get the server status with PHP. Is the Server offline or online.

Code:

<?php
ini_set("display_errors", TRUE);
include('./jsonRPCClient.php');
$bitcoin = new jsonRPCClient('http://bla:bla@111.111.111.111:8332/');
if ($bitcoin) {
  echo "online";
} else {
  echo "offline";
}
?>

dose not work, any idea?

Code:

<?php
ini_set("display_errors", TRUE);
include('./jsonRPCClient.php');
$bitcoin = new jsonRPCClient('http://bla:bla@111.111.111.111:8332/');
$getinfo = $bitcoin->getinfo();
if ($getinfo != '') {
  echo "online";
} else {
  echo "offline";
}
?>

Try that. Or something alike. the new jsonRPCClient command only opens the connection, you need to ask something to the server to get a response.

The credentials are wrong, most likely.

Maybe this is useful:

Are you making the call from a second box?

If credentials were wrong you'd be getting "Unable to connect to ..." with display errors.

Original code works.

ah!

rpcallowip=xxx.xxx.xxx.xxx

:P good call
That 403 would be returned if the flag was not set on bitcoin.conf ;)

rpcallow etc is all set!
if the server is online, $bitcoin->getinfo(); works.

I am trying now to get the status with fsockopen or other php commands hmmm

if rpc allow was not set you'd be getting "failed to open stream: Connection refused"

Found a solution:

Code:

<?php
 $ch = curl_init();
 
 curl_setopt($ch, CURLOPT_URL, "http://**:**@111.111.111.111:8332/");
 curl_setopt($ch, CURLOPT_HEADER, 0);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
 
 $res = curl_exec($ch);
 curl_close($ch);
 
 if($res) {
   echo "onlin";
 } else {
   echo "offline";
 }
?>

How about a try/catch block?

Code:

<?php
ini_set("display_errors", TRUE);
include('./jsonRPCClient.php');

try{
 $bitcoin = new jsonRPCClient('http://bla:bla@111.111.111.111:8332/');
 $getinfo = $bitcoin->getinfo();
  echo "online";
}catch(Exception $e){
  echo "offline: $e";
}
?>
