problema di deserializzazione WCF

mercoledì 16 maggio 2012 08:41

Ciao a tutti, sto cercando di capire perchè non riesco a deserializzare correttamente dei messaggi provenienti da un servizio di terze parti.

Dal trace log di WCF ricevo un messaggio di questo tipo:

<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:xs="http://www.w3.org/2000/10/XMLSchema" xmlns:tt="http://www.onvif.org/ver10/schema" xmlns:tptz="http://www.onvif.org/ver10/ptz/wsdl">

Le classi sono state create con svcutil e quella a cui fa riferimento il codice xml è definita:

Purtroppo invece che ricevere l'array dalla funzione GetPreset ricevo sempre null. Inoltre c'è una funzione simile che invece funziona, di seguito tutte le definizioni:

Ho provato anche deserializzare il codice xml direttamente ma in entrambi i casi ricevo degli errori. Qualcuno riuscirebbe a darmi una mano ?

grazie

Ciao,

istanzio il client wcf e poi effettuo la chiamata
```
using (PTZClient ptz = new PTZClient())
{
PTZPreset[] presets = ptz.GetPresets("Profile1");
PTZNode[] nodes = ptz.GetNodes();
}
```
la getNodes funziona (restituendomi un array) mentre la get preset mi restituisce l'array vuoto. Non ho nessun errore nè warning, il codice xml che avevo postato è preso dal trace di wcf, ma non riesce a deserializzare correttamente. Ho notato inoltre che con altre funzioni che richiedono un parametro in ingresso si manifesta lo stesso comportamento (array vuoto o null), mentre con funzioni senza parametri restituiscono correttamente il valore.

ciao

prova a testare il servizio con wcftestclient (disponibile digitandone il nome nella console di visual studio command prompt nel menu start)

se wcftestclient funziona, allora dovresti verificare il tuo proxy-client generato:

per testare la procedura di generazione del client che hai fatto tramite svcutil, ti consiglio di rimuovere il tutto e di agganciarti direttamente da visual studio cliccando sulle reference del progetto e selezionando poi "Add Service Reference". se il comportamento non varia, abbiamo la certezza che la procedura da te seguita era corretta

se invece il problema della deserializzazione continua ad avvenire, probabilmente dovrai impostare alcune configurazioni di dettaglio sulla serializzazione nel contratto di servizio: cambiare la configurazione del DataContractSerializer tramite il relativo attributo (http://msdn.microsoft.com/en-us/library/ms576151), o addirittura cambiare il serializzatore nel XmlSerializer con eventualmente le relative configurazioni sempre tramite attributo (http://msdn.microsoft.com/en-us/library/ms586952)

nel tuo caso, entrambi andrebbero messi sull'interfaccia di contratto del client (quella autogenerata tramite VS o svcutil)

prova anche a testare il servizio in soapUI (http://www.soapui.org/) per verificarne il fuzionamento

tienici aggiornati

a presto

Il servizio funziona correttamente e ritorna l'xml che avevo allegato, ho provato anche con soapUI.

Purtroppo non riesco ad aggiungere il servizio da visual studio perchè va in timeout quando tenta di scaricare il contratto, quindi non ho fatto altro che scaricare il wsdl a mano con le definizioni e utilizzare svcutil. Ho notato che su alcune funzioni c'è un avviso:
```
// CODEGEN: Il parametro 'Preset' richiede informazioni sullo schema aggiuntive che non possono essere acquisite utilizzando la modalità parametro. L'attributo specifico è 'System.Xml.Serialization.XmlElementAttribute'.
```
non se sia collegato con il problema che ho.

Invece per quanto riguarda gli attributi non ho capito precisamente come dovrei utilizzarli

grazie
