Salesforce/PHP - messages sortants (SOAP) - problème de limite de mémoire? DOMDocument :: loadXML() Fin prématurée des données dans un problème de balise?

Question

MISE À JOUR:

OK j'ai tout compris, ressemble fread a une limitation de taille du fichier, a changé cela

file_get_contents('php://input')

, mais maintenant avoir donner une SF java.net.SocketTimeoutException: Lire expiré erreur et rien du côté PHP. J'ai également ajouté set_time_limit (0); au script PHP qui si je comprends bien exécuter le script aussi longtemps que cela prend. Des pensées?

BTW: Je peux traiter jusqu'à 25 (que je l'ai testé) mais pas 100

---

J'utilise Salesforce pour envoyer des messages sortants (via SOAP) vers un autre serveur. Le serveur peut traiter environ 8 messages à la fois, mais ne renverra pas le fichier ACK si la requête SOAP contient plus de 8 messages. SF peut envoyer jusqu'à 100 messages sortants dans une requête SOAP et je pense que cela provoque un problème de mémoire avec PHP. Si je traite les messages sortants 1 par 1, tout va bien, je peux même faire 8 à la fois sans problèmes. Mais les plus gros ensembles ne fonctionnent pas.

erreur dans SF:

org.xml.sax.SAXParseException: Premature end of file 

Vous cherchez dans les journaux d'erreur HTTP, je vois que le message SOAP entrant semble être se couper de ce qui jette un avertissement PHP indiquant:

DOMDocument::loadXML() ... Premature end of data in tag ... 

PHP Fatal erreur:

Call to a member function getAttribute() on a non-object 

Cela me conduit à croire que PHP a un problème de mémoire et ne peut pas pa rse le message entrant en raison de sa taille.

Je pensais que je pouvais mettre:

ini_set('memory_limit', '64M'); // This has done nothing to fix the problem 

Mais Serait-ce la bonne approche? Y at-il un moyen que je pourrais définir cela pour augmenter dynamiquement avec la demande SOAP entrante?

Answer 1

Un problème de mémoire PHP dire

PHP Fatal error: Out of memory (allocated 250871808)... 

Ceci est plus susceptible d'être mal pris fin ou des données tronquées provenant de la plate-forme Salesforce - essayez de débogage la première erreur de SF.

EDIT:

OK, il semble que vous saisir des données d'une manière archaïque. Essayez de remplacer fread() par stream_get_contents(), ainsi que par echo $content directement après l'avoir vérifié.
