[SOAP] soapClient : requete complexe

**EurekaInstant** · 24/08/2012, 15h06

J'ai un problème pour les requêtes complexes SOAP avec l'objet soapClient de php5

PHP Version 5.3.3-1 sous ubuntu9.10

Voici la requête SOAP que je voudrais envoyé (ici le code est en xml pour mieux le visualiser)

Code :

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:epcglobal:epcis-query:xsd:1">
   <soapenv:Header/>
   <soapenv:Body>
       <urn:Poll>
         <queryName>SimpleEventQuery</queryName>
         <params>            
            <param>
               <name>EQ_action</name>
               <value>
		   <string>ADD</string>
                   <string>OBSERVE</string>
		   <string>DELETE</string>
               </value>
            </param>
         </params>
      </urn:Poll>
   </soapenv:Body>
</soapenv:Envelope>

Et voici le code PHP que j'utilise pour effectuer l'appel SOAP (donc l utilisation de SoapClient pour consumer un webservice distant via un WSDL)

Le code produit pour l'appel Soap n'est pas correct et provoque une horreur une erreur :p
(le code devrait être identique à la première section de code que j'ai posté plus haut)
Voici le code que j'obtiens (code qui n'est pas correct)

Le problème provient du array de value dans le passage de paramètres car le serveurSoap ou php convertit implicitement mes strings comme des noeuds <xsd:string>MonString</xsd:string>

Cela fait plusieurs jours que je suis dessus et je ne trouve pas de solution...
Si une personne à une idée je suis preneur ^^

voici le WSDL à disposition (c'est un WSDL faisait partie d un projet open source nommé fosstrak)

J'ai trouvé une réponse à mon problème grace à un commentaire (http://www.php.net/manual/en/soapvar.soapvar.php) trouvé dans la doc de PHP qui explique très bien l'utilisation de paramètres complexe dans les appel au web service en PHP via SOAP.

LA SOLUTION est d'utiliser new SoapVar("<maBalise>valeur</maBalise>", XSD_ANYXML);

Je poste le commentaire (on sait jms ça peut tjs aider quelqu'un ^^ )

It took me more than one day to figure out how to use the SoapVar object in a multilevel/complex SOAP request.
If you want to set-up a multilevel/complex SOAP call with parameters in subnodes, you can use the following methods:

    new SoapVar(2, XSD_INT, 'xsd:int'),

Après avoir compris le mécanisme j'ai pu élaborer ces quelques lignes et ainsi pallier à mon problème
