1. 下载 nusoap 库，点这里下载

下载文件 (已下载 122 次)

点击这里下载文件: nusoap-0.7.3.zip

2. 解压到 /app/vendors/nusoap ，目录结构类似：
/app/vendors/nusoap/lib
/app/vendors/nusoap/samples

3. 封装为一个component，保存到 /app/controllers/components/soap.php，以方便在controller里调用：

<?php
class SoapComponent extends Component 
{
var $defaultClientOptions = array(
   'endpoint' => '',
   'wsdl' => false,
   'proxyhost' => false,
   'proxyport' => false,
   'proxyusername' => false,
   'proxypassword' => false,
   'timeout' => 0,
   'response_timeout' => 20,
);

var $defaultCallOptions = array(
    'serviceUrl' => '',
    'operation' => '',
    'namespace' => 'http://tempuri.org',
    'soapAction' => '',
    'params' => array(),
    'debug' => false, // set to true to return debug info
    'encoding' => 'UTF-8',
    'rpcParams' => null,
    'style' => 'rpc',
    'headers' => false,
    'use' => 'encoded',
    'autoCheckWSDL' => true, // if serviceUrl end with "?WSDL" then set the client options['wsdl'] to be true
   );

function initialize(&$controller)
{
   vendor('nusoap/lib/nusoap');
}

function client($options)
{

   if(!is_array($options)) 
   {

   $options = am($this->defaultClientOptions, $options);
  
   return (new nusoap_client(
    $options['endpoint']
    , $options['wsdl']
    , $options['proxyhost']
    , $options['proxyport']
    , $options['proxyusername']
    , $options['proxypassword']
    , $options['timeout']
    , $options['response_timeout']
   ));
}

function call($options)
{
   $defaultOptions = $this->defaultCallOptions;

    {
     $clientOptions['wsdl'] = true;
    }
   }
  
   $client = $this->client($clientOptions);
   $client->soap_defencoding = $options['encoding'];
   $client->decode_utf8 = false;
   $result = $client->call($options['operation'], $options['params'], $options['namespace'], $options['soapAction'], $options['headers'], $options['rpcParams'], $options['style'], $options['use']);
  
   $return = array(
    'fault' => null,
    'error' => null,
    'result' => null,
   );
   if($client->fault) 
   {
    $return['fault'] = $result;
   }
   else

    $return['response'] = $client->response;
    $return['debug'] = $client->getDebug();
   }
   return $return;
}

*/
function debug($result)
{
   if ($result['fault']) {
    echo '<h2>Fault (Expect - The request contains an invalid SOAP body)</h2><pre>'; print_r($result['fault']); echo '</pre>';
   } else {
    if ($result['error']) {
     echo '<h2>Error</h2><pre>' . $result['error'] . '</pre>';
    } else {
     echo '<h2>Result</h2><pre>'; print_r($result['result']); echo '</pre>';
    }
   }
   echo '<h2>Request</h2><pre>' . htmlspecialchars($result['request'], ENT_QUOTES) . '</pre>';

   echo '<h2>Debug</h2><pre>' . htmlspecialchars($result['debug'], ENT_QUOTES) . '</pre>';
   }

}
?>

4. 在任意controller里添加测试：

备注：

1. 在构建服务端时，serviceUrl 须加 ?WSDL 后缀
2. 返回结果在：$soapRequest['result']
3.如果$soapRequest 中有debug选项，$result会包含调试信息，可通过$this->Soap->debug($result) 快速调试
