create_wsdl.php
1 <?php 2 3 include("Service.php"); 4 include("SoapDiscovery.class.php"); 5 6 $disco = new SoapDiscovery(‘Service‘, ‘my‘); //第一个参数是类名（生成的wsdl文件就是以它来命名的），即Service类，第二个参数是服务的名字（这个可以随便写）。 7 $disco->getWSDL();
client.php
1 <?php 2 header ("Content-Type: text/html; charset=utf-8"); 3 try { 4 ini_set(‘soap.wsdl_cache_enabled‘, "0"); 5 $client = new SoapClient(‘http://localhost/Service.php?wsdl‘); 6 echo $client->echostr("hello"); 7 echo $client->Add(28, 222); 8 } catch ( SoapFault $e ) { 9 print "client.php:". $e->getMessage (); 10 } 11 12 ?>
调用create_wsdl.php后生成wsdl文件，内容如下：注意下面红色地址
1 <?xml version="1.0" ?> 2 <definitions name="my" targetNamespace="urn:my" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="urn:my" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns="http://schemas.xmlsoap.org/wsdl/"> 3 <types xmlns="http://schemas.xmlsoap.org/wsdl/" /> 4 <portType name="myPort"><operation name="echostr"> 5 <input message="tns:echostrRequest" /> 6 <output message="tns:echostrResponse" /> 7 </operation> 8 <operation name="Add"> 9 <input message="tns:AddRequest" /> 10 <output message="tns:AddResponse" /> 11 </operation> 12 </portType> 13 <binding name="myBinding" type="tns:myPort"> 14 <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" /> 15 <operation name="echostr"> 16 <soap:operation soapAction="urn:my#Service#echostr" /> 17 <input><soap:body use="encoded" namespace="urn:my" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" /> 18 </input> 19 <output> 20 <soap:body use="encoded" namespace="urn:my" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" /> 21 </output> 22 </operation> 23 <operation name="Add"> 24 <soap:operation soapAction="urn:my#Service#Add" /> 25 <input><soap:body use="encoded" namespace="urn:my" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" /> 26 </input> 27 <output> 28 <soap:body use="encoded" namespace="urn:my" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" /> 29 </output> 30 </operation> 31 </binding> 32 <service name="my"> 33 <documentation /> 34 <port name="myPort" binding="tns:myBinding"><soap:address location="http://localhost:80/Service.php" /> 35 </port> 36 </service> 37 <message name="echostrRequest"> 38 <part name="str" type="xsd:string" /> 39 </message> 40 <message name="echostrResponse"> 41 <part name="echostr" type="xsd:string" /> 42 </message> 43 <message name="AddRequest"> 44 <part name="a" type="xsd:string" /> 45 <part name="b" type="xsd:string" /> 46 </message> 47 <message name="AddResponse"> 48 <part name="Add" type="xsd:string" /> 49 </message> 50 </definitions>
访问client.php可以看到返回结果.
