Failed to call .NET ASMX from PHP

Question

I have the following - a currently hosted SOAP service created in .NET that I am trying to call from PHP:

POST /ExampleService/ExampleService.asmx HTTP/1.1 Host: dev.examplesite.com Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://localhost:51713/ExampleService.asmx/RegisterPerson" <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Header> <UserCredentials xmlns="http://localhost:51713/ExampleService.asmx"> <UserID>string</UserID> <AuthKey>string</AuthKey> </UserCredentials> </soap:Header> <soap:Body> <RegisterPerson xmlns="http://localhost:51713/ExampleService.asmx"> <requestItem> <RequestResult>string</RequestResult> <Firstname>string</Firstname> <Lastname>string</Lastname> </requestItem> </RegisterPerson> </soap:Body> </soap:Envelope> 

and I'm trying to call it using the following PHP code:

 <?php $ns = "http://dev.examplesite.com/ExampleService/ExampleService.asmx"; $wsdl_url = "http://dev.examplesite.com/ExampleService/ExampleService.asmx?wsdl"; $client = new SOAPClient($wsdl_url); $header = new SoapHeader( $ns, 'UserCredentials', array( 'UserID' => "1", 'AuthKey' => "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX" ) ); $client->__setSoapHeaders($header); $params = array( 'Firstname' => 'John', 'Lastname' => 'Doe' ); $client->__soapCall('RegisterPerson',$params); ?> 

This results in the following error:

Fatal error: Uncaught SoapFault exception: [soap:MustUnderstand] Missing required header 'UserCredentials'. in /home/devops1/public_html/asmxtest/register.php:43 Stack trace: #0 /home/devops1/public_html/asmxtest/register.php(43): SoapClient->__soapCall('RegisterPerso...', Array) #1 {main} thrown in /home/devops1/public_html/asmxtest/register.php on line 43

I tried several other methods, but all of them were unsuccessful. One thing that concerns me is the fact that we go through the wire to this web service, which is already hosted on the test server, and localhost: 51713 is the sound signals. Should it be changed to a fully qualified domain name, for example dev.examplesite.com ?

Answer 1

For as easy as SoapClient, I have never been successful. In almost every case, we turned off our own process, which always seemed better.

Example:

 // set our headers to pass in cURL $headers = array( 'Content-type: text/xml;charset="utf-8"', 'Accept: text/xml', 'Cache-Control: no-cache', 'Pragma: no-cache', 'SOAPAction: ' . $action, 'Content-length: '.strlen($soap) ); // initiate cURL try { $_ch = curl_init(); curl_setopt($_ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($_ch, CURLOPT_URL, WEB_SERVICE_URL); curl_setopt($_ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($_ch, USERPWD, USER_ID . ":" . PASSWORD); curl_setopt($_ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($_ch, CURLOPT_TIMEOUT, 10); curl_setopt($_ch, CURLOPT_POST, true); curl_setopt($_ch, CURLOPT_POSTFIELDS, $soap); curl_setopt($_ch, CURLOPT_HTTPHEADER, $headers); // process the request and get the result back $response = curl_exec($_ch); curl_close($_ch); return $response; } catch (Exception $e) { capDebug(__FILE__, __LINE__, "Error calling the web service: " . $e->getMessage(), "/tmp/errors.log"); return false; } 

We had to massage the data later, but it always works!
