PHP企业级应用之WebService篇

国内用PHP写WebService的真的很少，网上资料也没多少，公司的项目开发过程中，经历了不少这方面的东西，写出来以供大家参考（谢谢老农提供的WSDL和程序文件）
客户端

<?php header ( "Content-Type: text/html; charset=utf-8" ); /* * 指定WebService路径并初始化一个WebService客户端 */ $ws = "http://soap/soapCspMessage.php?wsdl"; $client = new SoapClient ( $ws, array ('trace' => 1, 'uri' => 'http://www.zxsv.com/SoapDiscovery/' ) ); /* * 获取SoapClient对象引用的服务所提供的所有方法 */ echo ("SOAP服务器提供的开放函数:"); echo ('<pre>'); var_dump ( $client->__getFunctions () ); echo ('</pre>'); echo ("SOAP服务器提供的Type:"); echo ('<pre>'); var_dump ( $client->__getTypes () ); echo ('</pre>'); echo ("执行GetGUIDNode的结果:"); //$users = $client->GetUsers(); //var_dump($HelloWorld ); $parameters = array('uname'=>'zxsv',"upassword"=>'123'); $out = $client->HelloWorld($parameters); $datadb = $out->HelloWorldResponse; var_dump($out); ?> 

服务端

<?php class Member { public $UserId; public $Name; public function __construct($parmas){ $this->UserId = $parmas[0]; $this->Name = $parmas[1]; } } $servidorSoap = new SoapServer('testphp.xml',array('uri' => 'http://www.TestPHP.com/','encoding'=>'utf-8','soap_version' => SOAP_1_2 )); $servidorSoap->setClass(Testphp); $servidorSoap->handle(); class Testphp { public function HelloWorld($uid){ return array('HelloWorldResult'=>"mystring".$uid->{'uname'}.' and '.$uid->{'upassword'}); } public function GetMember($uid){ $s=array(); for($i=0;$i<$uid->{'uid'};$i++){ $s[] =&new Member(array($i, $uid->{'uname'}.'我测试'.$i)); } return array('GetMemberResult'=>$s); } } ?> 

 

到这里应该都看的懂吧
下面是WSDL文件

<?xml version="1.0" encoding="utf-8"?> <wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:tns="http://www.TestPHP.com/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" targetNamespace="http://www.TestPHP.com/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"> <wsdl:types> <s:schema elementFormDefault="qualified" targetNamespace="http://www.TestPHP.com/"> <s:element name="HelloWorld"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="upassword" type="s:string" /> </s:sequence> </s:complexType> </s:element> <s:element name="HelloWorldResponse"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="HelloWorldResult" type="s:string" /> </s:sequence> </s:complexType> </s:element> <s:element name="GetMember"> <s:complexType> <s:sequence> <s:element minOccurs="1" maxOccurs="1" name="uid" type="s:int" /> <s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string" /> </s:sequence> </s:complexType> </s:element> <s:element name="GetMemberResponse"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="GetMemberResult" type="tns:ArrayOfMember" /> </s:sequence> </s:complexType> </s:element> <s:complexType name="ArrayOfMember"> <s:sequence> <s:element minOccurs="0" maxOccurs="unbounded" name="Member" nillable="true" type="tns:Member" /> </s:sequence> </s:complexType> <s:complexType name="Member"> <s:sequence> <s:element minOccurs="1" maxOccurs="1" name="UserId" type="s:int" /> <s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string" /> </s:sequence> </s:complexType> </s:schema> </wsdl:types> <wsdl:message name="HelloWorldSoapIn"> <wsdl:part name="parameters" element="tns:HelloWorld" /> </wsdl:message> <wsdl:message name="HelloWorldSoapOut"> <wsdl:part name="parameters" element="tns:HelloWorldResponse" /> </wsdl:message> <wsdl:message name="GetMemberSoapIn"> <wsdl:part name="parameters" element="tns:GetMember" /> </wsdl:message> <wsdl:message name="GetMemberSoapOut"> <wsdl:part name="parameters" element="tns:GetMemberResponse" /> </wsdl:message> <wsdl:portType name="TestPHPSoap"> <wsdl:operation name="HelloWorld"> <wsdl:input message="tns:HelloWorldSoapIn" /> <wsdl:output message="tns:HelloWorldSoapOut" /> </wsdl:operation> <wsdl:operation name="GetMember"> <wsdl:input message="tns:GetMemberSoapIn" /> <wsdl:output message="tns:GetMemberSoapOut" /> </wsdl:operation> </wsdl:portType> <wsdl:binding name="TestPHPSoap" type="tns:TestPHPSoap"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="HelloWorld"> <soap:operation soapAction="http://www.TestPHP.com/HelloWorld" /> <wsdl:input> <soap:body use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> <wsdl:operation name="GetMember"> <soap:operation soapAction="http://www.TestPHP.com/GetMember" /> <wsdl:input> <soap:body use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:binding name="TestPHPSoap12" type="tns:TestPHPSoap"> <soap12:binding transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="HelloWorld"> <soap12:operation soapAction="http://www.TestPHP.com/HelloWorld" /> <wsdl:input> <soap12:body use="literal" /> </wsdl:input> <wsdl:output> <soap12:body use="literal" /> </wsdl:output> </wsdl:operation> <wsdl:operation name="GetMember"> <soap12:operation soapAction="http://www.TestPHP.com/GetMember" /> <wsdl:input> <soap12:body use="literal" /> </wsdl:input> <wsdl:output> <soap12:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="TestPHP"> <wsdl:port name="TestPHPSoap" binding="tns:TestPHPSoap"> <soap:address location="http://soap/goodwsdl/testphp.php" /> </wsdl:port> <wsdl:port name="TestPHPSoap12" binding="tns:TestPHPSoap12"> <soap12:address location="http://soap/goodwsdl/testphp.php" /> </wsdl:port> </wsdl:service> </wsdl:definitions> 

这里有返回的两个字段，一个是返回字符串，这个很好理解
<s:element name="HelloWorld">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string" />
            <s:element minOccurs="0" maxOccurs="1" name="upassword" type="s:string" />
          </s:sequence>
        </s:complexType>
      </s:element>
      <s:element name="HelloWorldResponse">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" name="HelloWorldResult" type="s:string" />
          </s:sequence>
        </s:complexType>
      </s:element>

这一段就字符串的
那返回数组的就比较麻烦了，我和老农搞了一两周才发现是WSDL文件写错了，看下面的一段
      <s:element name="GetMember">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="1" maxOccurs="1" name="uid" type="s:int" />
            <s:element minOccurs="0" maxOccurs="1" name="uname" type="s:string" />
          </s:sequence>
        </s:complexType>
      </s:element>
      <s:element name="GetMemberResponse">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" name="GetMemberResult" type="tns:ArrayOfMember" />
          </s:sequence>
        </s:complexType>
      </s:element>
      <s:complexType name="ArrayOfMember">
        <s:sequence>
          <s:element minOccurs="0" maxOccurs="unbounded" name="Member" nillable="true" type="tns:Member" />
        </s:sequence>
      </s:complexType>
      <s:complexType name="Member">
        <s:sequence>
          <s:element minOccurs="1" maxOccurs="1" name="UserId" type="s:int" />
          <s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string" />
        </s:sequence>
      </s:complexType>
第一段GetMember是输入，最重要的是GetMemberResponse这段，看type="tns:ArrayOfMember"这里，返回一个数组，WSDL中定义了ArrayOf这个，后面的就简单了，ArrayOfMember的类型是type="tns:Member" ，从name="Member"得到要返回的数组，完工。

 

这是我这边的一份代码，你可以学习下， function getSSOLoginID($sessionID) { if ($sessionID == "") { return ""; } // SOAP接続 $soapclient =& new soapclient('http'//localhost/AuthCheckService?wsdl',true); $soapclient->debug_flag=true; $soapclient->timeout = 500; $soapclient->response_timeout = 500; if($err = $soapclient->getError()){ execSSOLogWrite($err); return ""; } $proxy = $soapclient->getProxy(); if($err = $soapclient->getError()){ execSSOLogWrite($err); return ""; } $params = array('MISUMISESSION' => $sessionID); $result = $proxy->doAuthCheck($params); $status = $result['STATUS']; $userid = $result['USERID']; if ($status == "1") { return $userid; } else { return ""; } }
