php cannot send json sensor data

Votes:

0

In your manual the format is for GET requests: http: <probe_ip> : <port_number> / <token> ?content= <valid XML_or_JSON>

This format works if I send it with the browser URL. The same code works on another server if using text only (no JSON, no XML) I do not even get an answer or an error from prtg

The json_encode shows: {"prtg":{"result":[{"channel":"MyChannel","value":2483}]}}

My code:

<!DOCTYPE html>
<html>
<body>
<?php

$temperature = 2483;

	$prtgJson = array(
	'prtg' => array(
		'result' => array(array(
			'channel' => 'MyChannel',
			'value' => $temperature
		))
	)
	);

$stringToPush = "http://probe_ip:5050/S19?content=" . $prtgJson;

$xml = file_get_contents($stringToPush);

?>
</body>
</html>

http-get json php

Dear jmjobin

Please set the correct content type when pushing, in this case application/json.

Thank you so much for your help. How and where to set the content, should I create another json array? Could you please help me.

Hi there,

This should do the trick: 

<!DOCTYPE html>
<html>
<body>
<?php

$temperature = 2483;

	$prtgJson = array(
	'prtg' => array(
		'result' => array(array(
			'channel' => 'MyChannel',
			'value' => $temperature
		))
	)
	);

$stringToPush = "http://probe_ip:5050/S19?content=" . json_encode($prtgJson);

$xml = file_get_contents($stringToPush);

?>
</body>
</html>

Otherwise, you'll pushing a PHP array to PRTG, which it can't interpret.

Kind regards,

I inserted:

header('Content-Type: application/json');

If I add this line at the end:

var_dump($http_response_header, $http_response_body, $xml);

I receive

  [0]=>
  string(15) "HTTP/1.0 200 OK".....

but nothing else. The data never showed up on the sensor.

I added also the json_encode() and no result as well.

I think this is not working properly, I used other clouds and have no problems, only prtg shows problems.

I also tried to use a simple sensor and use the simple format with ?value=100 and the value never sets.
Tried it from the browser. No way to set a value.
Anyone is using this???

Any real simple example to use these functionalities???
I am stuck. Thank you if someone can help.

Some update: Made some test and I am sure about the code. The target actively refused the connection !? I add this line of code and got the error: error_reporting(0); ini_set('display_errors', 1); The error was reported as below:

<b>Warning</b>:  file_get_contents(http://myIp:5050/S19?content={&quot;prtg&quot;:{&quot;result&quot;:[{&quot;channel&quot;:&quot;MyChannel&quot;,&quot;value&quot;:&quot;2483&quot;}]}}): failed to open stream: No connection could be made because the target machine actively refused it.

<b>Notice</b>:  Undefined variable: http_response_header in <b>C:\Inetpub\vhosts\myServerName.com\httpdocs\test.php</b> on line <b>33</b><br />

Update and end. We could close the case. Found an error in our server setup. Thank you.
