PHP企业级应用之WebService篇

hb_sz

　　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
　　<?phpheader ( "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
　　<?phpclass 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 "";}}
