Web Services Tutorial

To aid in generating WSDL, you must provide a bunch of detailed information about your service. This is done via the dispatch map and the data type map.

• Normally, all object methods are SOAP accessable (except _name)

• The dispactch map does not need to be used, but aids the server class in knowing what parameters are used with the functions

• For multiple OUT parameters, you MUST use the dispatch mapping

• If you use dispatch mapping, you MUST have a map for each SOAP function

Dispatch Keys

• IN: An array of IN parameters for the method

• OUT: An array of OUT parameters for the method

• ALIAS: Can be used to specify a PHP function to handle the SOAP call (usefull for handling SOAP calls that use PHP keywords)

Dispatch Map Example


<?php $this->__dispatch_map['echoStructAsSimpleTypes'] =
    array(
        'in' => 
            array('inputStruct' => 
                '{http://soapinterop.org/xsd}SOAPStruct'),
                
        'out' => 
            array('outputString' => 'string', 
                  'outputInteger' => 'int', 
                  'outputFloat' => 'float'),
        
        'alias' => 'myEchoStructAsSimpleTypes'
        );

$this->__dispatch_map['echoStringSimple'] =
    array(
        'in' => 
            array('inputStringSimple' => 'string'),
        
        'out' => 
            array('outputStringSimple' => 'string'),
        );
?>
