PHP中soap的用法实例

本文实例讲述了php中soap的用法，分享给大家供大家参考。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";
   }
  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="http://www.w3.org/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";
   }
  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);
}
?>

希望本文所述对大家的php程序设计有所帮助。
