如何使用php连接wsdl api

Here is my code, and I can't figure out why it's not working.

$soapUrl = "http://airarabia.isaaviations.com/webservices/services/AAResWebServices?wsdl";

$xml_post_string = '<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soap:Header><wsse:Security soap:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"><wsse:UsernameToken wsu:Id="UsernameToken-17855236" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"><wsse:Username>xxx</wsse:Username><wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">xxx</wsse:Password></wsse:UsernameToken></wsse:Security></soap:Header><soap:Body xmlns:ns2="http://www.opentravel.org/OTA/2003/05"><ns2:OTA_AirAvailRQ EchoToken="11868765275150-1300257933" PrimaryLangID="en-us" SequenceNmbr="1" Target="LIVE" TimeStamp="2018-10-08T11:39:35" Version="20061.00"><ns2:POS><ns2:Source TerminalID="Farhath/Farhath"><ns2:RequestorID ID="WSBENZTRAVELS" Type="4" /><ns2:BookingChannel Type="12" /></ns2:Source></ns2:POS><ns2:OriginDestinationInformation><ns2:DepartureDateTime>2018-10-30T00:00:00</ns2:DepartureDateTime><ns2:OriginLocation LocationCode="CMB" /><ns2:DestinationLocation LocationCode="RUH" /></ns2:OriginDestinationInformation><ns2:OriginDestinationInformation><ns2:DepartureDateTime>2018-11-30T00:00:00</ns2:DepartureDateTime><ns2:OriginLocation LocationCode="RUH" /><ns2:DestinationLocation LocationCode="CMB" /></ns2:OriginDestinationInformation><ns2:TravelerInfoSummary><ns2:AirTravelerAvail><ns2:PassengerTypeQuantity Code="ADT" Quantity="1" /></ns2:AirTravelerAvail></ns2:TravelerInfoSummary></ns2:OTA_AirAvailRQ></soap:Body></soap:Envelope>';

$headers = array(

"Host: airarabia.isaaviations.com",
"Content-Type: application/soap+xml; charset=utf-8",
"Content-Length: ".strlen($xml_post_string)
); 

$url = $soapUrl;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

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

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

$parser = simplexml_load_string($response);

print_r($parser);

I am able to connect to the API, but couldn't get a result.

Do you have any idea, any solution ?

I wrote a class that helps to simplify generating SOAP XML for a Laravel package. Here is the class:

<?php

namespace Mtownsend\CollectionXml\Soap;

use SoapClient;

/**
 * Use the SoapFactory class to build a valid SOAP request
 * but prevent it from making an actual request
 * and capture the data it builds for use.
 */
class SoapFactory extends SoapClient
{
    public $soapRequest;
    public $soapLocation;
    public $soapAction;
    public $soapVersion;

    public function __construct($wsdl, $options)
    {
        parent::__construct($wsdl, $options);
    }

    /**
     * Build the SOAP xml string
     * @param  array  $soapRootAndXml [$soapRoot => $xml]
     * @return Mtownsend\CollectionXml\Soap\SoapFactory
     */
    public function build(array $soapRootAndXml)
    {
        $this->ProcessXMLRequest($soapRootAndXml);
        return $this;
    }

    /**
     * Override the SoapClient __doRequest method.
     */
    public function __doRequest($request, $location, $action, $version, $one_way = 0)
    {
        $this->soapRequest = $request;
        $this->soapLocation = $location;
        $this->soapAction = $action;
        $this->soapVersion = $version;
        return ''; // Return a string value or the SoapClient throws an exception
    }

    /**
     * A proxy for the getSoapRequest method.
     * @return string
     */
    public function getSoapXml()
    {
        return $this->getSoapRequest();
    }

    /**
     * Return the SOAP request XML.
     * @return string
     */
    public function getSoapRequest()
    {
        return $this->soapRequest;
    }

    /**
     * Return the SOAP request location url.
     * @return string
     */
    public function getSoapLocation()
    {
        return $this->soapLocation;
    }

    /**
     * Return the SOAP request action.
     * @return string
     */
    public function getSoapAction()
    {
        return $this->soapAction;
    }

    /**
     * Return the SOAP request version number.
     * @return string
     */
    public function getSoapVersion()
    {
        return $this->soapVersion;
    }
}

If you would like to use it, save the contents to SoapFactory.php and include it in your script.

Next, get your raw xml ready. Don't try to SOAPify it or anything. Store it in a variable $xml_post_string.

You may need to change your soap root if it doesn't work. I've connected to soap endpoints in the past that use 'xmlBody'.

$soapRoot = 'xmlBody';

$soapFactory = new SoapFactory($soapUrl, ['trace' => 1]));

$soapXml = $soapFactory->build([$soapRoot => $xml_post_string])->getSoapXml();

Now you can try a curl call.

$headers = array(

"Host: airarabia.isaaviations.com",
"Content-Type: application/soap+xml; charset=utf-8",
"Content-Length: ".strlen($soapXml)
); 

$url = $soapUrl;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $soapXml);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

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

$parser = simplexml_load_string($response);

print_r($parser);

There's no guarantee with SOAP, but try that and see if it gets you anywhere.
