Send xml with a post request to wcf service on iis

Question

SOLVED with this link

I'm developing a wcf service, with rest pattern. Now it is on a IIS server.

It has got a method callable with a post, which has to receive a xml data.

I'm trying to send this xml (with other parameter), but I'm getting only deserial errors:

in System.ServiceModel.Dispatcher.OperationFormatter.DeserializeRequest(Message message, Object[] parameters)

in System.ServiceModel.Dispatcher.DemultiplexingDispatchMessageFormatter.DeserializeRequest(Message message, Object[] parameters)

in System.ServiceModel.Dispatcher.UriTemplateDispatchFormatter.DeserializeRequest(Message message, Object[] parameters)

in System.ServiceModel.Dispatcher.DispatchOperationRuntime.DeserializeInputs(MessageRpc& rpc)

in System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc)

in System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc)

in System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage31(MessageRpc& rpc)

in System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)

This is the request:

retista=0019&hashedStrig=dkfjdkfjd&dati=<ArrayOfWrapClienti xmlns="http://schemas.datacontract.org/2004/07/MultipayOnline" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><WrapClienti><CODRETE>0018</CODRETE><CODICE>20685</CODICE><NOME>A.T.E.R. Azienda Territoriale</NOME><INDIRIZZO>PIAZZA POZZA</INDIRIZZO><CITTA>Verona</CITTA><CAP>37123</CAP><PROV>VR</PROV><CODICEFISCALE>00223640236</CODICEFISCALE><PIVA>223640236</PIVA><EMAIL/><ESPOSIZ_CONTABILE>937,02</ESPOSIZ_CONTABILE><STATO>FALSE</STATO></WrapClienti></ArrayOfWrapClienti>

and this is the xml I'm trying to send:

<ArrayOfWrapClienti xmlns="http://schemas.datacontract.org/2004/07/aaa" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<WrapClienti>
<CODRETE>1111</CODRETE>
<CODICE>111</CODICE>
<NOME>AAA</NOME>
<INDIRIZZO>PIAZZA</INDIRIZZO>
<CITTA>AAA</CITTA>
<CAP>111</CAP>
<PROV>aa</PROV>
<CODICEFISCALE>111</CODICEFISCALE>
<PIVA>223611140236</PIVA>
<EMAIL/>
<ESPOSIZ_CONTABILE>1111</ESPOSIZ_CONTABILE>
<STATO>FALSE</STATO>
</WrapClienti>
</ArrayOfWrapClienti>

If you click here, you can find out how an xml is returned by my wcf. I thought I have to send the same xml with other data, but I get the deserial error.

Why?

How can I send the xml to my wcf? In this test phase, I'm using this.

If I can give to you other useful infos, ask me and I'll write them here.

UPDATE: The text of the error message says that there are invalid data at root level, row 1, pos 1. Also if I put

<?xml version="1.0" encoding="utf-8" ?>

at the root level.

Maybe are there some missing headers?

UPDATE server side:

this is how my server wcf is configured:

    [OperationContract]
    [WebGet(UriTemplate = "cliente.xml?retista={codret}&cliente={codiceCliente}&H={hashedString}", ResponseFormat = WebMessageFormat.Xml)]
    List<WrapClienti> GetClienteXML(string codret, string codiceCliente, string hashedString);

and this is the called method:

    public GenericResponse SetClientiXML(List<WrapClienti> clienti, string retista, string hashedString) 
    {
        var api = new API();
        return api.SetClienti(clienti, retista, hashedString);        
    }

as you can I see, I don't manage any xml/json deserialzing phase, it is managed by the wcf routine. For example, if I send a json list, it converts it to a List. This is what also with xml I want to see, but I'm getting the error at the top of this question.

ANOTHER UPDATE: I have to send 3 parameters in xml, so.... this is my last attempt, I think it is more correct than previouses. Now the server gives null reference error:

<?xml version="1.0" encoding="utf-8" ?>
<SetClientiXML
  xmlns="http://tempuri.org/">
  <XMLRequest>
    <ArrayOfWrapClienti
      xmlns="http://schemas.datacontract.org/2004/07/aaa"
      xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
      <WrapClienti>
        <CODRETE>111</CODRETE>
        <CODICE>111</CODICE>
        <NOME>aaa</NOME>
        <INDIRIZZO>aaa</INDIRIZZO>
        <CITTA>aaa</CITTA>
        <CAP>aaa</CAP>
        <PROV>aa</PROV>
        <CODICEFISCALE>111</CODICEFISCALE>
        <PIVA>2236401111236</PIVA>
        <EMAIL/>
        <ESPOSIZ_CONTABILE>111</ESPOSIZ_CONTABILE>
        <STATO>FALSE</STATO>
      </WrapClienti>
    </ArrayOfWrapClienti>
    <RETISTA>1111</RETISTA>
    <HASHEDSTRING>oklkokokokok</HASHEDSTRING>
  </XMLRequest>
</SetClientiXML>

I have also created this class:

[DataContract]
public class XMLRequest
{
    [DataMember]
    public List<WrapClienti> XML;
    [DataMember]
    public string RETISTA;
    [DataMember]
    public string HASHEDSTRING;
    public XMLRequest() { }
    public XMLRequest(List<WrapClienti> x, string r, string h)
    {
        this.HASHEDSTRING = h;
        this.XML = x;
        this.RETISTA = r;
    }
}

and the portotype now is:

public GenericResponse SetClientiXML(XMLRequest xr)

Answer 1

Does this work?

            string input =
                "<ArrayOfWrapClienti xmlns=\"http://schemas.datacontract.org/2004/07/MultipayOnline\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">" +
                "<WrapClienti>" +
                "<CODRETE>0018</CODRETE>" +
                "<CODICE>20685</CODICE>" +
                "<NOME>A.T.E.R. Azienda Territoriale</NOME>" +
                "<INDIRIZZO>PIAZZA POZZA</INDIRIZZO>" +
                "<CITTA>Verona</CITTA>" +
                "<CAP>37123</CAP>" +
                "<PROV>VR</PROV>" +
                "<CODICEFISCALE>00223640236</CODICEFISCALE>" +
                "<PIVA>223640236</PIVA>" +
                "<EMAIL/>" +
                "<ESPOSIZ_CONTABILE>937,02</ESPOSIZ_CONTABILE>" +
                "<STATO>FALSE</STATO>" +
                "</WrapClienti>" +
                "</ArrayOfWrapClienti>";

            input = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" + input;​

Here is code to serialize and de-serialize your xml

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

                xmlRequest = new XMLRequest()
