<pre name="code" class="php"><span style="font-size:14px;">$host = $_SERVER ['HTTP_HOST'];$module = trim ( $_GET ['m'] );include __DIR__.'/'.$module.".class.php";if (isset($_GET ['ws']) && $_GET['ws']==1) { $soap = new SoapServer ( "http://" . $host . "/wsdl/service.php?m={$module}", array('cache_wsdl'=>0) ); $soap->setClass ( $module); $soap->handle ();} else { include __DIR__ . '/WsdlModel.class.php'; $wsdl = new wsdl (); $wsdl->generateWsdl ( $module, "http://" . $host . "/wsdl/service.php?m={$module}&ws=1" ); unset ( $wsdl );}</span><span style="font-size:14px;">3.定义一个类作为测试类</span>
<pre name="code" class="php"><span style="font-size:14px;">class Food{ /** * function name: getFood * @param string 食物 * @return string * @soap */ public function getFood($food){ $arr['food'] = "我喜欢吃".$food; return json_encode($arr); } /** * function name: getEat * @return string * @soap */ public function getEat(){ return "food"; }}</span>4.在客服端进行调用
<span style="font-size:14px;">1.通过php自带扩展soap调用</span>
<pre name="code" class="php"><span style="font-size:14px;">try { $soap = new SoapClient ( "http://www.mytest.com/wsdl/service.php?m=Food", array ('cache_wsdl' => 0) ); $result = $soap->__soapCall ( "getFood", array("apple")); echo $result;} catch ( SoapFault $e ) { echo $e->getMessage (); echo $e->getTraceAsString ();} catch ( Exception $e ) { echo $e->getMessage ();}</span>2.通过开源类nusoap调用
<pre name="code" class="php"><span style="font-size:14px;">include __DIR__ . "/Nusoap.class.php";$client = new nusoap_client ( 'http://www.mytest.com/wsdl/service.php?m=Food', 'wsdl' );$client->soap_defencoding = 'utf-8';$client->decode_utf8 = false;$client->xml_encoding = 'utf-8';$client->debugLevel = 2;$result = $client->call ( 'getFood', array ("苹果"));echo $result;</span>3.通过java的axis2进行调用
<pre name="code" class="java"><span style="font-size:14px;">import javax.xml.namespace.QName;import org.apache.axis2.AxisFault;import org.apache.axis2.addressing.EndpointReference;import org.apache.axis2.client.Options;import org.apache.axis2.rpc.client.RPCServiceClient;import org.apache.axis2.transport.http.HTTPConstants;public class TestTwoSoap{public static void main(String[] args) throws AxisFault {// 使用RPC方式调用WebService RPCServiceClient serviceClient = new RPCServiceClient(); Options options = serviceClient.getOptions(); options.setProperty(HTTPConstants.CHUNKED, "false");// 指定调用WebService的URL EndpointReference targetEPR = new EndpointReference( "http://www.mytest.com/wsdl/service.php?m=Food&ws=1"); options.setTo(targetEPR); // 指定方法的参数值 Object[] requestParam = new Object[] {"dd"}; // 指定方法返回值的数据类型的Class对象 Class[] responseParam = new Class[] {String.class}; // 指定要调用的getGreeting方法及WSDL文件的命名空间 QName requestMethod = new QName("http://www.mytest.com/wsdl/service.php?m=Food&ws=1", "getFood"); // 调用方法并输出该方法的返回值 try {System.out.println(serviceClient.invokeBlocking(requestMethod, requestParam, responseParam)[0]);} catch (AxisFault e) {e.printStackTrace();} } }</span> 0 0
