详解PHP中soap的两种方式（用/不用wsdl文件）的用法实例（附服务器端代码）

PHP中soap的具体用法分析如下：

PHP 使用soap有两种方式。

一、用wsdl文件

服务器端：

<?php
 class service
 {
   public function HelloWorld()
    {
       return  "Hello Camnpr.Com";
    }
   public  function Add($a,$b)
    {
       return $a+$b;
    }
 }
 $server=new SoapServer('soap.wsdl',array('soap_version' => SOAP_1_2));
 $server->setClass("service");
 $server->handle();
 ?>

资源描述文件，可以用工具(zend studio)生成。其实就是一个xml文件。

<?xml version="1.0" encoding="UTF-8"?>
 <wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://localhost/interface/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="2001/XMLSchema" name="soap" targetNamespace="http://localhost/interface/">
   <wsdl:types>
     <xsd:schema targetNamespace="http://localhost/interface/">
       <xsd:element name="HelloWorld">
         <xsd:complexType>
           <xsd:sequence>
             <xsd:element name="in" type="xsd:string"/>
           </xsd:sequence>
         </xsd:complexType>
       </xsd:element>
       <xsd:element name="HelloWorldResponse">
         <xsd:complexType>
           <xsd:sequence>
             <xsd:element name="out" type="xsd:string"/>
           </xsd:sequence>
         </xsd:complexType>
       </xsd:element>
       <xsd:element name="Add">
        <xsd:complexType>
         <xsd:sequence>
          <xsd:element name="in" type="xsd:int"></xsd:element>
         </xsd:sequence>
        </xsd:complexType>
       </xsd:element>
       <xsd:element name="AddResponse">
        <xsd:complexType>
         <xsd:sequence>
         <xsd:element name="out" type="xsd:int"></xsd:element>
         </xsd:sequence>
        </xsd:complexType>
       </xsd:element>
     </xsd:schema>
   </wsdl:types>
    <wsdl:message name="AddRequest">    <wsdl:part name="a" type="xsd:int"></wsdl:part>
    <wsdl:part name="b" type="xsd:int"></wsdl:part>
   </wsdl:message>
   <wsdl:message name="AddResponse">
    <wsdl:part name="c" type="xsd:int"></wsdl:part>
   </wsdl:message>
   <wsdl:portType name="TestSoap">     <wsdl:operation name="Add">
      <wsdl:input message="tns:AddRequest"></wsdl:input>
      <wsdl:output message="tns:AddResponse"></wsdl:output>
     </wsdl:operation>
   </wsdl:portType>
   <wsdl:binding name="soapSOAP" type="tns:TestSoap">
    <soap:binding style="document"
     transport="http://schemas.xmlsoap.org/soap/http" />
    <wsdl:operation name="Add">
     <soap:operation soapAction="http://localhost/interface/Add" />
     <wsdl:input>
      <soap:body use="literal"
       namespace="http://localhost/interface/" />
     </wsdl:input>
     <wsdl:output>
      <soap:body use="literal"
       namespace="http://localhost/interface/" />
     </wsdl:output>
    </wsdl:operation>
   </wsdl:binding>
   <wsdl:service name="TestSoap">
     <wsdl:port binding="tns:soapSOAP" name="soapSOAP">
       <soap:address location="http://localhost/interface/myservice.php"/>
     </wsdl:port>
   </wsdl:service>
 </wsdl:definitions>

客户端调用：

<?php
 $soap = new SoapClient('http://localhost/interface/soap.wsdl');
 echo $soap->Add(1,2);
 ?>

二、不用wsdl文件

服务器端：

<?php
 class service
 {
   public function HelloWorld()
    {
       return  "Hello Camnpr.Com";
    }
   public  function Add($a,$b)
    {
       return $a+$b;
    }
 }
 $server=new SoapServer(null,array('uri' => "abcd"));
 $server->setClass("service");
 $server->handle();
 ?>

客户端：

<?php
 try{
  $soap = new SoapClient(null,array(
    "location" => "http://localhost/interface/soap.php",
    "uri"      => "abcd",  //资源描述符服务器和客户端必须对应
    "style"    => SOAP_RPC,
    "use"      => SOAP_ENCODED
       ));
 echo $soap->Add(1,2);
 }catch(Exction $e){
  echo print_r($e->getMessage(),true);
 }
 ?>
