PHP如何调用ASP.NET的webservice

Question

假如我要调用
https://api.securefreedom.com/nuriche/Webservice/OnlineAPI.asmx?op=CheckEmail
用户名与密码为xxx.
我看了看，这个api的request的格式为POST /nuriche/Webservice/OnlineAPI.asmx HTTP/1.1
Host: api.securefreedom.com
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>

    </CheckEmail>
  </soap12:Body>
</soap12:Envelope>求如何发送$ch = curl_init ();

curl_setopt ( $ch, CURLOPT_URL, "https://api.securefreedom.com/nuriche/Webservice/OnlineAPI.asmx?op=CheckEmail" );
curl_setopt ( $ch, CURLOPT_HEADER, false );
curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, true );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt(  $ch, CURLOPT_POSTFIELDS, 这个地方需要拼数据?);

php有现成的SOAP扩展<?php$client = new SoapClient("some.wsdl");
$client->SomeFunction($a, $b, $c);$client->__soapCall("SomeFunction", array($a, $b, $c));
$client->__soapCall("SomeFunction", array($a, $b, $c), NULL,
                    new SoapHeader(), $output_headers);
$client = new SoapClient(null, array('location' => "http://localhost/soap.php",
                                     'uri'      => "http://test-uri/"));
$client->SomeFunction($a, $b, $c);
$client->__soapCall("SomeFunction", array($a, $b, $c));
$client->__soapCall("SomeFunction", array($a, $b, $c),
                    array('soapaction' => 'some_action',
                          'uri'        => 'some_uri'));
?>
