soap的两种实现方式：WSDL和Non-WSDL

1.non-wsdl模式利用php的soap扩展实现：

server

<?php
class HandleClass {
    public function test() {
        return '23434';
    }
}

//uri必填
$soap_server = new SoapServer(null, array('uri'=>'http://soap/','location'=>'http://localhost/soap/server.php'));
$soap_server->setClass('HandleClass');
$soap_server->handle();

client

<?php
//location和uri必填
$soap_client = new SoapClient(null, array('location'=>'http://localhost/soap/server.php','uri'=>'http://soap/'));
echo $soap_client->test();

output:

23434

2.wsdl利用php的soap扩展实现

server:

<?php
class service {
	public function HelloWorld() {
		return "Hello";
	}
}
$server = new SoapServer ('helloworld.wsdl');
$server->setClass ( "service" );
$server->handle ();

client:

<?php
$client = new SoapClient ( "helloworld.wsdl" );
echo $client->HelloWorld ();

wsdl:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://www.example.org/helloworld/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="helloworld" targetNamespace="http://www.example.org/helloworld/">
  <wsdl:types>
    <xsd:schema targetNamespace="http://www.example.org/helloworld/">
      <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:schema>
  </wsdl:types>
  <wsdl:message name="HelloWorldRequest">

  </wsdl:message>
  <wsdl:message name="HelloWorldResponse">
    <wsdl:part name="HelloWorldReturn" type="xsd:string"/>
  </wsdl:message>
  <wsdl:portType name="helloworld">
    <wsdl:operation name="HelloWorld">
      <wsdl:input message="tns:HelloWorldRequest"/>
      <wsdl:output message="tns:HelloWorldResponse"/>
    </wsdl:operation>
  </wsdl:portType>
  <wsdl:binding name="helloworldSOAP" type="tns:helloworld">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="HelloWorld">
      <soap:operation soapAction="http://www.example.org/helloworld/HelloWorld"/>
      <wsdl:input>
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output>
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="helloworld">
    <wsdl:port binding="tns:helloworldSOAP" name="helloworldSOAP">
      <soap:address location="http://localhost/soap/wsdlServer.php"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

output:

Hello

BTW，zendstudio 10中可以通过插件的 方式支持wsdl的图形化编辑，见下图

3.non-wsdl模式利用zend的soap组件实现

handle:

<?php
class Example_Manager {

	/**
	 * Returns list of all products in database
	 *
	 * @return array
	 */
	public function getProducts() {
		$db = Zend_Registry::get ( 'Zend_Db' );
		$sql = "SELECT * FROM products";
		return $db->fetchAll ( $sql );
	}

	/**
	 * Returns specified product in database
	 *
	 * @param integer $id        	
	 * @return array Exception
	 */
	public function getProduct($id) {
		if (! Zend_Validate::is ( $id, 'Int' )) {
			throw new Exception ( 'Invalid input' );
		}
		$db = Zend_Registry::get ( 'Zend_Db' );
		$sql = "SELECT * FROM products WHERE id = '$id'";
		$result = $db->fetchAll ( $sql );
		if (count ( $result ) != 1) {
			throw new Exception ( 'Invalid product ID: ' . $id );
		}
		return $result;
	}
}

 

server：

public function soapserverAction()
    {
    	$this->getHelper('viewRenderer')->setNoRender(true);

    	$server = new Zend_Soap_Server(null, array('uri' => 'http://zenddemo.com/index/soapserver', 'location'=> 'http://zenddemo.com/index/soapserver'));

    	$server->setClass('Example_Manager');

    	$server->handle();
    }

client:

public function soapclientAction() {
    	$this->getHelper('viewRenderer')->setNoRender(true);
    	$options = array(
    			'location' => 'http://zenddemo.com/index/soapserver',
    			'uri'      => 'http://zenddemo.com/index/soapserver'
    	);

    	try {
    		$client = new Zend_Soap_Client(null, $options);
    		$result = $client->getProducts();
    		print_r($result);
    	} catch (SoapFault $s) {
    		die('ERROR: [' . $s->faultcode . '] ' . $s->faultstring);
    	} catch (Exception $e) {
    		die('ERROR: ' . $e->getMessage());
    	}
    }

 4.wsdl模式用zend的soap组件实现

handle：同上

server:

public function soapwsdlserverAction() {
    	$this->getHelper('viewRenderer')->setNoRender(true);

    	$server = new Zend_Soap_AutoDiscover();
    	$server->setClass('Example_Manager');
    	$server->setUri('http://zenddemo.com/index/soapserver');
    	$server->handle();
    }

client:

public function soapclientAction() {
    	$this->getHelper('viewRenderer')->setNoRender(true);

    	try {
    		$client = new Zend_Soap_Client('http://zenddemo.com/index/soapwsdlserver');	
    		$result = $client->getProducts();
    		print_r($result);
    	} catch (SoapFault $s) {
    		die('ERROR: [' . $s->faultcode . '] ' . $s->faultstring);
    	} catch (Exception $e) {
    		die('ERROR: ' . $e->getMessage());
    	}
    }
