Post XML with HTTPS Authentication using PHP and cURL

Code

Recently I needed to post XML to a particular API and this API required HTTPS authentication. So I needed to send a username / password with the request.

This was pretty straightforward in C#.NET ( at least from my foggy memory ). You needed to use NetworkCredentials. But it was a bit difficult to find a similar way of doing this in PHP… but eventually I found this gem.

This uses cURL which is just a library to send and receive data from remote sites. Now all I needed was a neat way of using cURL to post XML… and I found a neat implementation here.

Two plus two and you get …

$request_xml = "<?xml version='1.0' encoding='utf-8'?>
<request>
	<id>12345</id>
	<email>eoin@dolepaddy.com</email>
<request>";

//Initialize handle and set options
$username = 'dolepaddy';
$password = 'secret123';
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, 'https://connect.tosomeserver.com/xmlrpc'); 
curl_setopt($ch, CURLOPT_USERPWD, $username.':'.$password);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_TIMEOUT, 4); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $request_xml); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: close'));

//Execute the request and also time the transaction ( optional )
$start = array_sum(explode(' ', microtime()));
$result = curl_exec($ch); 
$stop = array_sum(explode(' ', microtime()));
$totalTime = $stop - $start;

//Check for errors ( again optional )
if ( curl_errno($ch) ) {
	$result = 'ERROR -> ' . curl_errno($ch) . ': ' . curl_error($ch);
} else {
	$returnCode = (int)curl_getinfo($ch, CURLINFO_HTTP_CODE);
	switch($returnCode){
		case 200:
			break;
		default:
			$result = 'HTTP ERROR -> ' . $returnCode;
			break;
	}
}

//Close the handle
curl_close($ch);

//Output the results and time
echo 'Total time for request: ' . $totalTime . "\n";
echo $result;

  3. Thanks for the code, its a life saver. We changed the bottom of the code a bit to give better feedback on errors and thought I would share it.

    //Check for errors ( again optional )
$error = false;
if ( curl_errno($ch) ) {
        $error = 'ERROR -> ' . curl_errno($ch) . ': ' . curl_error($ch);
} else {
        $returnCode = (int)curl_getinfo($ch, CURLINFO_HTTP_CODE);
        switch($returnCode){
                case 200:
                        break;
                default:
                        $error = 'HTTP ERROR -> ' . $returnCode;
                        break;
        }
}

//Close the handle
curl_close($ch);

//Output the results and time
echo 'Total time for request: ' . $totalTime . "\n";
if ($error)
{
        echo $error;
}
echo $result;

  4. U rocks. Thanks a Lot for this code!!!

    Just one thing. If you change
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
    to
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);

    The receiver php script could see $_SERVER[‚PHP_AUTH_USER‘] and $_SERVER[‚PHP_AUTH_PW‘]

  7. How does one deal with sending XML across HTTPS without needing the user/pass vars? I’m trying to do an XML POST via HTTPS, as outlined in a shopping cart API. No PHP examples though. I tried commenting out lines 8, 9, 12 & 13… but no go. I’m a long time PHP user, so it’s frustrating that it’s busting my balls here, I’ve worked with curl plenty, but never really for HTTPS or XML applications. Any ideas? Thanks!

    1. Try…

      $ch = curl_init();
      curl_setopt($ch, CURLOPT_URL, 'https://connect.tosomeserver.com/xmlrpc');
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($ch, CURLOPT_POSTFIELDS, $request_xml);
      curl_close($ch);

  8. This is awesome I have been looking for something like this for a while. However it doesn’t quite get me there. I seem to be getting a 415 error. Any ideas? Thanks for the help.
