∟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, Hello_There_Non_WSDL.php:

<?php
#  Hello_There_Non_WSDL.php
#- Copyright 2009-2015 (c) HerongYang.com. All Rights Reserved.
#
   $client = new SoapClient(null, array(
      'location' =>
         "https://www.herongyang.com/Service/Hello_SOAP_11.php",
      'uri'      => "https://www.herongyang.com/Service/",
      'trace'    => 1 ));

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

   $return = $client->__soapCall("Hello",array());
   echo("\nReturning value of __soapCall() call: ".$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(34) "https://www.herongyang.com/Service/"
  ["location"]=>
  string(51) "https://www.herongyang.com/Service/Hello_SOAP_11.php"
  ["trace"]=>
  int(1)
  ["_soap_version"]=>
  int(1)
}

Returning value of __soapCall() call:
Dumping request headers:
POST /Service/Hello_SOAP_11.php HTTP/1.1
Host: www.herongyang.com
Connection: Keep-Alive
Content-Type: text/xml; charset=utf-8
SOAPAction: "https://www.herongyang.com/Service/#Hello"
Content-Length: 399


Dumping request:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
 xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
 xmlns:ns1="https://www.herongyang.com/Service/"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema"
 xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
 SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
 <SOAP-ENV:Body>
  <ns1:Hello/>
 </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Dumping response headers:
HTTP/1.1 200 OK
Server: Apache
Keep-Alive: timeout=2, max=200
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/xml

Dumping response:
<soapenv:Envelope
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:hy="https://www.herongyang.com/Service/">
  <soapenv:Header/>
  <soapenv:Body>
    <hy:HelloResponse>
      Hello from server - herongyang.com.
    </hy:HelloResponse>
  </soapenv:Body>
</soapenv:Envelope>

The output shows that:

My Hello_There_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 "https://www.herongyang.com/Service/#Hello".
