Hello_There_Dump.php - Debugging SOAP Messages
This section provides a tutorial example on how to use SOAP client functions to make Web service call on the target SOAP node and print detailed debug information.
After learning the basic functions of the SoapClient class, I revised my Hello_There.php client program to get more information on how SOAP Extension works, and to show you how to debug a SOAP client program. The new client program is called, Hello_There_Dump.php:
<?php # Hello_There_Dump.php #- Copyright 2009-2015 (c) HerongYang.com. All Rights Reserved. # $client = new SoapClient ("http://herongyang.com/Service/Hello_WSDL_11_SOAP.wsdl", array('trace' => 1)); echo("\nDumping client object:\n"); var_dump($client); echo("\nDumping client object functions:\n"); var_dump($client->__getFunctions()); $return = $client->Hello(); echo("\nReturning value of Hello() call: ".$return); $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 (3) { ["trace"]=> int(1) ["_soap_version"]=> int(1) ["sdl"]=> resource(6) of type (Unknown) } Dumping client object functions: array(1) { [0]=> string(36) "string Hello(string $helloInputPart)" } Returning value of Hello() call: Hello from server - herongyang.com. Returning value of __soapCall() call: Hello from server - herongyang.com. Dumping request headers: POST /Service/Hello_SOAP_11.php HTTP/1.1 Host: www.herongyang.com Connection: Keep-Alive User-Agent: PHP-SOAP/7.3.0 Content-Type: text/xml; charset=utf-8 SOAPAction: "https://www.herongyang.com/Service/Hello" Content-Length: 235 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/"> <SOAP-ENV:Body> <ns1:HelloRequest/> </SOAP-ENV:Body> </SOAP-ENV:Envelope> Dumping response headers: HTTP/1.1 200 OK Server: Apache X-Powered-By: PHP/7.2.14 Keep-Alive: timeout=2, max=199 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 is very useful. It confirms that:
