How can I send SOAP XML via Curl and PHP?

Question 1

This has been bugging me for days; I'm trying to send a SOAP post via Curl but I just keep getting a "couldn't connect to host" error, but, I really can't see how.

I have an ASP version which works fine with the same URL and data. I think it's just a PHP/Curl thing.

I currently have the following code (the CURLOPT_POSTFIELDS data is a valid SOAP envelope string):

$soap_do = curl_init();
curl_setopt($soap_do, CURLOPT_URL,            "https://xxx.yyy.com:517/zzz.asmx" );
curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($soap_do, CURLOPT_TIMEOUT,        10);
curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($soap_do, CURLOPT_POST,           true );            
curl_setopt($soap_do, CURLOPT_POSTFIELDS,     '<soap:Envelope>...</soap:Envelope>'); 
curl_setopt($soap_do, CURLOPT_HTTPHEADER,     array('Content-Type: text/xml; charset=utf-8', 'Content-Length: '.strlen('<soap:Envelope>...</soap:Envelope>') ));

if(curl_exec($soap_do) === false)
{                
    $err = 'Curl error: ' . curl_error($soap_do);
    curl_close($soap_do);
    return $err;
}
else
{
    curl_close($soap_do); 
    return 'Operation completed without any errors';
}

So any ideas why it just errors all the time?

The ASP version works fine! The code is:

Set xmlhttp = server.Createobject("MSXML2.ServerXMLHTTP")
xmlhttp.Open "POST","https://xxx.yyy.com:517/zzz.asmx"
xmlhttp.setRequestHeader "Content-Type", "text/xml; charset=utf-8"
xmlhttp.Send('<soap:Envelope>...</soap:Envelope>')

Question 2

Thanx a lot buddy, your code has worked for me.

Here is the code:

$soap_do = curl_init(); 
curl_setopt($soap_do, CURLOPT_URL,            $url );   
curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10); 
curl_setopt($soap_do, CURLOPT_TIMEOUT,        10); 
curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);  
curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false); 
curl_setopt($soap_do, CURLOPT_POST,           true ); 
curl_setopt($soap_do, CURLOPT_POSTFIELDS,    $post_string); 
curl_setopt($soap_do, CURLOPT_HTTPHEADER,     array('Content-Type: text/xml; charset=utf-8', 'Content-Length: '.strlen($post_string) )); 
curl_setopt($soap_do, CURLOPT_USERPWD, $user . ":" . $password);

$result = curl_exec($soap_do);
$err = curl_error($soap_do);

Question 3

This topic should help you solving your problem.

Adapted to your problem :

$xml = simplexml_load_string($ch_result, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/");
$ns = $xml->getNamespaces(true);
$soap = $xml->children($ns['env']);
$res = $soap->Body->children($ns['ns2']);

foreach ($res->LookupResponse as $item) {
    echo $item->Name.PHP_EOL;
}

Question 4

Step #1: Register the user.

Register a user at http://localhost:8080/#/register and make sure you can log in via the web interface.

Step #2: Obtain an OAuth2 token.

Information required for obtaining an OAuth2 token:

OAuth2 client id (see application.yml)
OAuth2 secret (see application.yml)
The user name and password used to register the new user.
Required scope/s

Then, obtain an OAuth 2 token from the server:

curl -X POST -vu client:secret http://localhost:8080/oauth/token -H "Accept: application/json" -d "username=username&password=password&grant_type=password&scope=read&client_id=clientid&client_secret=secret"

.. returns something like this:

{"access_token":"7916d326-0f7f-430f-8e32-c5135a121052","token_type":"bearer","refresh_token":"2c69ca58-a657-4780-b5d8-dc965d518e9e","expires_in":1037,"scope":"read"}

Step #3: Use the token in calls to protected resources:

Then, the auth token must be supplied in the header on every call:

curl http://localhost:8080/app/rest/books -H "Authorization: Bearer 7916d326-0f7f-430f-8e32-c5135a121052"

Question 5

If anyone should be interested, i have provided the correct answer:

$soapUrl = "http://privpakservices.schenker.nu/package/package_1.3/packageservices.asmx?op=SearchCollectionPoint";

$xml_post_string = '<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><SearchCollectionPoint xmlns="http://privpakservices.schenker.nu/"><customerID>XXX</customerID><key>XXXXXX-XXXXXX</key><serviceID></serviceID><paramID>0</paramID><address>RiksvŠgen 5</address><postcode>59018</postcode><city>Mantorp</city><maxhits>10</maxhits></SearchCollectionPoint></soap12:Body></soap12:Envelope>';

$headers = array(
"POST /package/package_1.3/packageservices.asmx HTTP/1.1",
"Host: privpakservices.schenker.nu",
"Content-Type: application/soap+xml; charset=utf-8",
"Content-Length: ".strlen($xml_post_string)
); 

$url = $soapUrl;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($ch); 
curl_close($ch);

$response1 = str_replace("<soap:Body>","",$response);
$response2 = str_replace("</soap:Body>","",$response1);

$parser = simplexml_load_string($response2);

Question 6

Your post size is exceeding your set post_max_size of 8MB. Try increasing this to something like 64MB (or higher, depending on the size of the posted data) using in php.ini:

post_max_size=64M

or in a script:

ini_set('post_max_size', '64M');
