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();

?>

<?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/">

      <xsd:element name="Add">

    </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"

      <soap:address location="http://localhost/interface/myservice.php"/>

    </wsdl:port>

  </wsdl:service>

</wsdl:definitions>

<?php

$soap = new SoapClient('http://localhost/interface/soap.wsdl');

echo $soap->Add(1,2);

?>

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();

?>

<?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);

}

?>
