PHP中soap的使用例子

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);

}
?>
