Calling REST via PHP

Hi,

I was trying out the cURL example to get a new SeesionKey. The following are the only changes I made to the code along with my credentials. But it is not still working. Can someone help with that?

What other settings do I have to pass? Ultimately, I will use the new SessionKey to LoginAsGuest. I appreciate any additional hint on that.

Have you confirmed that you can run the operation using either a REST client like Postman or the built-in REST Client?

Thanks Gawain for responding.

Yes, both worked fine for me. For the $data part, I am not really sure if that is equivalent with the request body part which requires only the IpAddress. I was not sure how to pass it to cURL.

The returned object was:

{"Message":"An error has occurred."}

You need ip and businessUnit at a min if I remember correctly.

 {
  "IpAddress": "",
  "BusinessUnit": 2
}

I just tried this

but it didn't work. The buit-in REST Client returns a SessionKey without the 'BusinessUnit. It needs only 'IpAddress'. Same with Postman.

I will get this in a function later.

$login = 'unsername:group:location';
$password = 'password';
$url = 'domain.tessituranetworkramp.com/.../New';
$data =  array('IpAddress'=> '17.16.1.1');

  $ch = curl_init(); 
  curl_setopt($ch, CURLOPT_USERPWD,"$login:$password");
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_POST, 1); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
  curl_setopt($ch, CURLOPT_POSTFIELDS,  http_build_query($data)); 


   $result = curl_exec($ch);
   if(curl_errno($ch) !== 0) { error_log('cURL error when connecting to ' . $url . ': ' . curl_error($ch)); } 
   curl_close($ch);
   print_r($result); 

Thanks Travis. I got it working now. These were the changes I made.

1) For POST method http_build_query is not required. I believe it is for GET.

2) I didn't need to pass any ip address. I used empty string. And It doesn't have to be an array.

3) The timeouts were not significant for this call. So, I didn't use those lines.

Thanks again. I appreciate.

The ip was simply a place holder and yes timeouts are not needed, but if you got it to work without using http_build_query, then post up your approach (to help others). To expand on this for others... Http_build_query is not specific to get or post. It simply builds the query string format (and easier to understand). For the array in the example above, http_build_query would output  IpAddress=17.16.1.1

If you really do not want to use http_build_query, then loop through the array and build the post args, which is what I use (example below).

$data =  array('IpAddress'=> '17.16.1.1');

//Build postfield string from data array
	$params = '';
	foreach($data as $key=>$value){
		$params .= $key.'='.$value.'&';
	}
	$params = trim($params, '&');

...

  curl_setopt($ch, CURLOPT_POSTFIELDS,$params);

Also, I will finish the original example soon. That will allow for GET, POST, PUT in one function. It was my intention to continue building on this thread, but a website redesign project got in my way and I kind of left it die. But your post gave me a renewed sense of purpose.

This is what worked for me. I am returning the error number if there is one, or the $result returned on success. I am not doing delete that is why I returned false in the switch statement.

Looks good!
