php使用NuSoap产生webservice结合WSDL让asp.net调用(31)

Defining New Data Structures

WSDL 一个重要的方面是它封装了一个或多个 XML 结构，允许程序员通过 service 来描述数据结构，为了说明 NuSOAP 如何支持这个，我会在 Programming with NuSOAP Part 2 文章中的 SOAP struct 实例中加入 WSDL 代码。

service 代码的改变已经显示在 Hello, World 实例中，但是它也包含了定义 Person 数据结构的代码：

					<?php // Pull in the NuSOAP code require_once('nusoap.php'); // Create the server instance $server = new soap_server(); // Initialize WSDL support $server->configureWSDL('hellowsdl2', 'urn:hellowsdl2'); // Register the data structures used by the service $server->wsdl->addComplexType( 'Person', 'complexType', 'struct', 'all', '', array( 'firstname' => array('name' => 'firstname', 'type' => 'xsd:string'), 'age' => array('name' => 'age', 'type' => 'xsd:int'), 'gender' => array('name' => 'gender', 'type' => 'xsd:string') ) ); $server->wsdl->addComplexType( 'SweepstakesGreeting', 'complexType', 'struct', 'all', '', array( 'greeting' => array('name' => 'greeting', 'type' => 'xsd:string'), 'winner' => array('name' => 'winner', 'type' => 'xsd:boolean') ) ); // Register the method to expose $server->register('hello',                    // method name array('person' => 'tns:Person'),          // input parameters array('return' => 'tns:SweepstakesGreeting'),    // output parameters 'urn:hellowsdl2',                         // namespace 'urn:hellowsdl2#hello',                   // soapaction 'rpc',                                    // style 'encoded',                                // use 'Greet a person entering the sweepstakes'        // documentation ); // Define the method as a PHP function function hello($person) { $greeting = 'Hello, ' . $person['firstname'] . '. It is nice to meet a ' . $person['age'] . ' year old ' . $person['gender'] . '.'; $winner = $person['firstname'] == 'Scott'; return array( 'greeting' => $greeting, 'winner' => $winner ); } // Use the request to (try to) invoke the service $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server->service($HTTP_RAW_POST_DATA); ?> 除了支持 WSDL 的附加代码之外，service 方法的代码本身也有一点改变，使用 WSDL ，不再需要使用 soapval 对象来为返回值指定名称和数据类型。
