Solicitudes de SOAP en .NET
Estamos intentando usar solicitudes SOAP para interactuar con una API de reserva usando Visual Studio C #.
Nos hemos interconectado con un servicio web de otra API sin problema, pero este está resultando problemático.
Lo hemos agregado como Referencia de servicio y Visual Studio ha generado todas las clases para él y las entradas web.config para que todo parezca bien.
Sin embargo, cuando intentamos realizar una solicitud simple al servicio SOAP del cliente, obtenemos el siguiente error:
Namespace = 'com.hrs.soap.hrs' no es compatible con rpc \ literal SOAP. El elemento envoltorio debe ser no calificado.
El código es:
PingRequest pingrequest = new PingRequest();
SoapServiceClient service = new SoapServiceClient();
service.ping(pingrequest);
Esto se ha agregado en el archivo web.config:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="HRSSoapServiceBinding" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="..."
binding="basicHttpBinding" bindingConfiguration="HRSSoapServiceBinding"
contract="HRSService.HRSSoapService" name="HRSSoapServicePort" />
</client>
</system.serviceModel>
De acuerdo con la documentación, la solicitud debe ser similar a la siguiente:
<complexType name="PingRequest">
<complexContent>
<extension base="tns:Request">
<sequence>
<element name="echoData" type="xsd:string"/>
</sequence>
</extension>
</complexContent>
</complexType>

Instalamos Fiddler y no hay ninguna solicitud XML que podamos ver, probablemente porque lanza una excepción antes de que se envíe algo.
¿Qué es exactamente lo que necesitamos cambiar en nuestra configuración para que esto funcione?
ACTUALIZAR
WSDL: Disponible [aquí] [1]
ACTUALIZAR
Siguiendo los excelentes consejos de davidfmatheson, he copiado el WSDL localmente y he realizado las enmiendas como se sugiere. Sigo recibiendo el mismo error aunque posiblemente en un lugar diferente:
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
BLL.HRSService.pingResponse BLL.HRSService.HRSSoapService.ping(BLL.HRSService.pingRequest request) {
return base.Channel.ping(request);
}
public BLL.HRSService.HRSPingResponse ping(BLL.HRSService.HRSPingRequestWrapper ping1) {
BLL.HRSService.pingRequest inValue = new BLL.HRSService.pingRequest();
inValue.ping = ping1;
BLL.HRSService.pingResponse retVal = ((BLL.HRSService.HRSSoapService)(this)).ping(inValue);
return retVal.pingResponse1;
}
La línea que falla es lavolver base.Channel.ping (solicitud); con errorNamespace = 'com.hrs.soap.hrs' no es compatible con rpc \ literal SOAP. El elemento envoltorio debe ser no calificado.
También intenté establecer explícitamente el SOAPBinding:
Exception Details: System.InvalidOperationException: Namespace='com.hrs.soap.hrs' is not supported with rpc\literal SOAP. The wrapper element has to be unqualified.

Bien, ahora he modificado el estilo de enlace de SOAP para documentar en mi WSDL local y he recreado las clases y tengo un error diferente:
