使用NUSOAP或SOAPCLIENT的PHP RAW XML POST-错误

Question

我正在尝试执行肥皂请求，该请求成功地在邮递员上工作。我总是出错。你能检查我的代码吗？

代码：

require_once('libs/nusoap/lib/nusoap.php');

$endpoint = "http://www.holidaywebservice.com/HolidayService_v2/HolidayService2.asmx?wsdl";

  $soap_request .= "<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'>";
  $soap_request .= "  <soapenv:Body>";
  $soap_request .= "   <GetHolidaysAvailable xmlns='http://www.holidaywebservice.com/HolidayService_v2/'>";
  $soap_request .= "      <countryCode xmlns='http://www.holidaywebservice.com/HolidayService_v2/'>UnitedStates</countryCode>";
  $soap_request .= "   </GetHolidaysAvailable>";
  $soap_request .= "  </soap:Body>";
  $soap_request .= "</soap:Envelope>";

$client = new nusoap_client($endpoint, false);

$msg = $client->serializeEnvelope($soap_request);

$result=$client->send($msg, $endpoint);

print_r($result);

错误：

Array（[faultcode] => soap：Client [faultstring] => System.Web.Services.Protocols.SoapException：服务器未在System.Web处识别HTTP标头SOAPAction：http://www.holidaywebservice.com/HolidayService_v2/HolidayService2.asmx?wsdl的值。 System.Web.Services.Protocols.SoapServerProtocol.RouteRequest（SoapServerMessage消息）位于System.Web.Services.Protocols.SoapServerProtocol.Initialize（）处于System.Web.Services.Proapcols.ServerProtocolFactory的Services.Protocols.Soap11ServerProtocolHelper.RouteRequest（）。 Create（Type type，HttpContext context，HttpRequest request，HttpResponse response，Boolean＆abortProcessing）[详细信息=>）

在邮递员中，一切正常
