PHP中soap的用法实例

PHP 使用soap有两种方式。

一、用wsdl文件

服务器端：

复制代码 代码如下:

<?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。

复制代码 代码如下:

<?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" targetNamespace="http://localhost/interface/">
  <wsdl:types>
    <xsd:schema targetNamespace="http://localhost/interface/">
      <xsd:element>
        <xsd:complexType>
          <xsd:sequence>
            <xsd:element type="xsd:string"/>
          </xsd:sequence>
        </xsd:complexType>
      </xsd:element>
      <xsd:element>
        <xsd:complexType>
          <xsd:sequence>
            <xsd:element type="xsd:string"/>
          </xsd:sequence>
        </xsd:complexType>
      </xsd:element>
      <xsd:element>
       <xsd:complexType>
        <xsd:sequence>
         <xsd:element type="xsd:int"></xsd:element>
        </xsd:sequence>
       </xsd:complexType>
      </xsd:element>
      <xsd:element>
       <xsd:complexType>
        <xsd:sequence>

<xsd:element type="xsd:int"></xsd:element>
        </xsd:sequence>
       </xsd:complexType>
      </xsd:element>
    </xsd:schema>
  </wsdl:types>
   <wsdl:message>    <wsdl:part type="xsd:int"></wsdl:part>
   <wsdl:part type="xsd:int"></wsdl:part>
  </wsdl:message>
  <wsdl:message>
   <wsdl:part type="xsd:int"></wsdl:part>
  </wsdl:message>
  <wsdl:portType>     <wsdl:operation>
     <wsdl:input message="tns:AddRequest"></wsdl:input>
     <wsdl:output message="tns:AddResponse"></wsdl:output>
    </wsdl:operation>
  </wsdl:portType>
  <wsdl:binding type="tns:TestSoap">
   <soap:binding
    transport="http://schemas.xmlsoap.org/soap/http" />
   <wsdl:operation>
    <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>
    <wsdl:port binding="tns:soapSOAP">
      <soap:address location="http://localhost/interface/myservice.php"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

客户端调用：

复制代码 代码如下:

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

二、不用wsdl文件

服务器端：

复制代码 代码如下:
