Using SOAP Extension in non-WSDL Mode

This section provides a tutorial example on how to use SOAP client functions to make Web service call without using the WSDL standard on the target SOAP node and print detailed debug information.

I think we had enough fun with the WSDL mode. Let's try the non-WSDL mode now. Here is the third version of my Get_Temperature.php SOAP client program, Get_Temperature_Non_Wsdl.php:

<?php # Get_Temperature_Non_Wsdl.php
# Copyright (c) 2005 by Dr. Herong Yang
#
   $zip = "123456";
   $client = new SoapClient(null, array(
      'location' => 
         "http://services.xmethods.net:80/soap/servlet/rpcrouter",
      'uri'      => "urn:xmethods-Temperature-Demo", 
      'trace'    => 1 ));

   echo("\nDumping client object:\n");
   var_dump($client);

   $return = $client->__soapCall("getTemp",array($zip));
   echo("\nReturning value of __soapCall() call: ".$return);

   echo("\nDumping request headers:\n" 
      .$client->__getLastRequestHeaders());

   echo("\nDumping request:\n".$client->__getLastRequest());

   echo("\nDumping response headers:\n"
      .$client->__getLastResponseHeaders());

   echo("\nDumping response:\n".$client->__getLastResponse());
?>

If you run this sample script, you will get:

Dumping client object:
object(SoapClient)#1 (4) {
  ["uri"]=>
  string(29) "urn:xmethods-Temperature-Demo"
  ["location"]=>
  string(54) "http://services.xmethods.net:80/soap/servlet/rpcrouter"
  ["trace"]=>
  int(1)
  ["_soap_version"]=>
  int(1)
}

Returning value of __soapCall() call: 52

Dumping request headers:
POST /soap/servlet/rpcrouter HTTP/1.1
Host: services.xmethods.net
Connection: Keep-Alive
User-Agent: PHP SOAP 0.1
Content-Type: text/xml; charset=utf-8
SOAPAction: "urn:xmethods-Temperature-Demo#getTemp"
Content-Length: 508

Dumping request:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
 xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
 xmlns:ns1="urn:xmethods-Temperature-Demo" 
 xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" 
 SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
 <SOAP-ENV:Body><ns1:getTemp>
  <param0 xsi:type="xsd:string">123456</param0>
 </ns1:getTemp></SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Dumping response headers:
HTTP/1.1 200 OK
Date: Wed, 05 Oct 2005 02:02:46 GMT
Server: Enhydra-MultiServer/3.1.1b1
Status: 200

Servlet-Engine: Enhydra Application Server/3.1.1b1 (JSP 1.1;

X-Cache: MISS from www.xmethods.net

Connection: Keep-Alive

Dumping response:
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope
 xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<ns1:getTempResponse
 xmlns:ns1="urn:xmethods-Temperature-Demo"
 SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<return xsi:type="xsd:float">52.0</return>
</ns1:getTempResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The output shows that:

  • My Get_Temperature_Non_Wsdl.php works the same as the WSDL mode version.
  • If you compare this output with the WSDL output, SOAP Extension generates the request headers with one difference: SOAPAction is not blank any more. It has the value of "urn:xmethods-Temperature-Demo#getTemp".
  • SOAP Extension also generates the request message differently in non-WSDL mode. The input parameter is provided with an element named as "param0". In the WSDL version, that element is named as "zipcode".
