SOAP PHP：如何将请求文件转换为PHP函数调用

Question

I'm beginning with the SOAP lib of PHP and i can't figure out how to execute my request :

The server has a user friendly API which gives me the request to pass but i can't tell how I am supposed to do so.

Here is the point I currently am :

$soap = new SoapClient("https://www.dmc.sfr-sh.fr/DmcWS/1.5.6/MessagesUnitairesWS?wsdl");

$soap->getSingleCallCra();

and the request i should pass :

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://servicedata.ws.dmc.sfrbt/">
 <soapenv:Header>
  <ser:authenticate>
   <serviceId>********</serviceId>
   <servicePassword>******</servicePassword>
   <spaceId>*******</spaceId>
   <lang>fr_FR</lang>
  </ser:authenticate>
 </soapenv:Header>
 <soapenv:Body>
  <ser:getSingleCallCra>
   <beginDate>2017-10-17T00:00:00</beginDate>
  </ser:getSingleCallCra>
 </soapenv:Body>
</soapenv:Envelope>

The SOAP client does work for other function with no parameter but i get a translated java NPE exception when i call this function.

Can anyone tell me how i can pass the parameters and authentification to the function ?

Thanks.

$soap = new SoapClient("https://www.dmc.sfr-sh.fr/DmcWS/1.5.6/MessagesUnitairesWS?wsdl");

To add headers to a soapcall use the __setSoapHeaders method like this:

$soap->__setSoapHeaders(array(
  //(namespace, name, data)
  new SoapHeader("http://servicedata.ws.dmc.sfrbt/",'authenticate',array(
    'serviceId' => '********',
    'servicePassword' => '******',
    'spaceId' => '*******',
    'lang' => 'fr_FR',
  ))
));

These parameters will go into the soap body. In PHP you can use objects or associative arrays as input as they are both interpreted into xml as key => value pairs.

$soap_body_parameters = array(
  'beginDate' => '2017-10-17T00:00:00',
);

$response = $soap->getSingleCallCra($soap_body_parameters);

print_r($response);

The return value of the soapclient class is always an object, so remember to use the arrow notation '$object->property' to get the relevant data out.

You can also create a class like this, that will deal with the headers, data extraction, etc. in the background for each call

class sfr_soap {
  function __construct($serviceId, $servicePassword, $spaceId, $lang = 'fr_FR'){
    $url = "https://www.dmc.sfr-sh.fr/DmcWS/1.5.6/MessagesUnitairesWS?wsdl";
    $this->client = new SoapClient($url);
    $soap->__setSoapHeaders(array(
        new SoapHeader("http://servicedata.ws.dmc.sfrbt/",'authenticate',array(
            'serviceId' => $serviceId,
            'servicePassword' => $servicePassword,
            'spaceId' => $spaceId,
            'lang' => $lang,
        ))
    ));
  }
  public function __call($name, $args = array()){
    $response = $this->client->$name($args);
    // do something with the response here, like extract the meaningful parts of the data
    return $response;
  }
}

init like this

$sfr = new sfr_soap($serviceId, $servicePassword, $spaceId);

or like this if you want to specify the language

$sfr = new sfr_soap($serviceId, $servicePassword, $spaceId, $lang);

use like this

$data = $sfr->getSingleCallCra(array(
  'beginDate' => '2017-10-17T00:00:00'
));
