SOAP请求和响应

Question

How to do the request using this kind of SOAP Request XML in PHP?

http://115.248.39.80/biyahekoapi/domesticair.asmx.

I am using CodeIgniter to develop such website with flight booking. I had tried SoapClient and CURL but no response.

    $url        = $API_DETAILS['URL']."?WSDL"; 
    $params     = array('encoding' => 'UTF-8', 'soap_version' => SOAP_1_2, 'trace' => 1, 'login' => $API_DETAILS['USER'], 'password' => $API_DETAILS['PASS']);
    $client     = new SoapClient($url, $params); 

    $security_param = array(
        "WebProviderLoginId"    => $API_DETAILS['USER'],
        "WebProviderPassword"   => $API_DETAILS['PASS']
    );
    $item_param = array(
        "Origin"        => $B_ORIGIN,
        "Destination"   => $B_DESTINATION,
        "TravelDate"    => $DEP_DATE
    );
    $journey_param = array(
        "Item"  => $item_param
    );
    $request_param = array(
        "BookingType"           => $B_WAY,
        "JryDetails"            => $journey_param,
        "ClassType"             => "E",
        "Airlinecodes"          => "",
        "No_of_Adults"          => $B_ADULTS,
        "No_of_Childs"          => $B_CHILD,
        "No_of_Infants"         => $B_INFANT,
        "SeniorCitizen"         => $B_SENIOR,
        "ResidentofPhilippines" => 1,
        "TransFeeFlag"          => $FEE_DETAILS['DOMESTIC']
    );
    $result_params = array(
        "pobjSecurity"      => $security_param,
        "PstrInput"         => array(
            "AvailabilityRequest"   => $request_param
        ),
        "PstrFinalOutPut"   => NULL,
        "pstrError"         => NULL
    );
    //print_r($result_params);
    $result = $client->__soapCall("AirGetAvailability", array($result_params)); 

    print_r($result);

When I run this code, it gives me this:

stdClass Object([AirGetAvailabilityResult] => [pstrError] => Data at the root level is invalid. Line 1, position 1.)

What part is wrong?

Here is my CURL code:

$soapAction = $API_DETAILS['URL'] . '?WSDL';
            $soapUrl    = $API_DETAILS['URL'];
            $B_RETURN   = '';
            $DEP_DATE   = date('m/d/Y', strtotime($B_DEPARTURE));
            $xml_post_string = htmlentities('<AvailabilityRequest><BookingType>O</BookingType><JryDetails><Item><Origin>'.$B_ORIGIN.'</Origin><Destination>'.$B_DESTINATION.'</Destination><TravelDate>'.$DEP_DATE.'</TravelDate></Item></JryDetails><ClassType>E</ClassType><Airlinecodes></Airlinecodes><No_of_Adults>'.$B_ADULTS.'</No_of_Adults><No_of_Childs>'.$B_CHILD.'</No_of_Childs><No_of_Infants>'.$B_INFANT.'</No_of_Infants><SeniorCitizen>'.$B_SENIOR.'</SeniorCitizen><ResidentofPhilippines>1</ResidentofPhilippines><TransFeeFlag>'.$FEE_DETAILS['DOMESTIC'].'</TransFeeFlag></AvailabilityRequest>');

            $text_string = '<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:soap12="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap12:Body><AirGetAvailability xmlns="http://www.biyaheko.com/biyahekoapi/domesticair/"><pobjSecurity><WebProviderLoginId>'.$API_DETAILS['USER'].'</WebProviderLoginId><WebProviderPassword>'.$API_DETAILS['PASS'].'</WebProviderPassword></pobjSecurity><PstrInput>'.$xml_post_string.'</PstrInput><PstrFinalOutPut /><pstrError /></AirGetAvailability><soap12:Body></soap12:Envelope>';

            //echo $text_string;

            $headers = array(
                "POST /biyahekoapi/domesticair.asmx HTTP/1.1",
                "Host: 115.248.39.80",
                "Content-Type: application/soap+xml; charset=utf-8",
                "Content-Length: ".strlen($text_string)
            ); 

            try{
                $url = $soapUrl;

                $ch = curl_init();
                curl_setopt($ch, CURLOPT_URL, $url);
                //curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
                //curl_setopt($ch, CURLOPT_USERPWD, '"'.$API_DETAILS['USER'].':'.$API_DETAILS['PASS'].'"');
                curl_setopt($ch, CURLOPT_POST, true);
                curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);                     
                curl_setopt($ch, CURLOPT_POSTFIELDS, $text_string);                             
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

                $response = curl_exec($ch); 
                curl_close($ch);

                $response1 = str_replace("<soap12:Body>","",$response);
                $response2 = str_replace("</soap12:Body>","",$response1);

                $parser = simplexml_load_string($response2);

                echo $parser;
            }catch(exception $E){
                echo 'Error: ' . $E.message();
            }
