Wir versuchen, SOAP-Anforderungen zu verwenden, um mithilfe von Visual Studio C # mit einer Buchungs-API zu interagieren.

Wir haben ohne Probleme eine Schnittstelle zu einem Webdienst einer anderen API hergestellt, aber dieser erweist sich als problematisch.

Wir haben es als Dienstreferenz hinzugefügt und Visual Studio hat alle Klassen für das Objekt und die Einträge in der Datei web.config generiert, sodass alles in Ordnung zu sein scheint.

Wenn wir jedoch versuchen, eine einfache Anfrage an den Client-SOAP-Dienst zu richten, wird der folgende Fehler angezeigt:

Namespace = 'com.hrs.soap.hrs' wird in rpc \ literal SOAP nicht unterstützt. Das Wrapper-Element muss unqualifiziert sein.

Der Code lautet:

PingRequest pingrequest = new PingRequest();    
SoapServiceClient service = new SoapServiceClient();
service.ping(pingrequest);

Folgendes wurde in der Datei Web.config hinzugefügt:

<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"

            messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
            useDefaultWebProxy="true">

              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>

Laut Dokumentation sollte die Anfrage wie folgt aussehen:

<complexType name="PingRequest">
    <complexContent>
        <extension base="tns:Request">
            <sequence>
                <element name="echoData" type="xsd:string"/>
            </sequence>
        </extension>
    </complexContent>
</complexType>

Wir haben Fiddler installiert und es wird keine XML-Anfrage durchlaufen, die wir sehen können, vermutlich, weil sie eine Ausnahme auslöst, bevor etwas gesendet wird.

Was genau müssen wir in unserem Setup ändern, damit dies funktioniert?

AKTUALISIEREN

WSDL: Verfügbar [hier] [1]

AKTUALISIEREN

Nach Davidfmathesons hervorragendem Rat habe ich die WSDL lokal kopiert und die vorgeschlagenen Änderungen vorgenommen. Ich erhalte immer noch den gleichen Fehler, obwohl möglicherweise an einer anderen Stelle:

[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;
        }

Die Linie, die ausfällt, ist diereturn base.Channel.ping (Anfrage); mit fehlerNamespace = 'com.hrs.soap.hrs' wird in rpc \ literal SOAP nicht unterstützt. Das Wrapper-Element muss unqualifiziert sein.

Ich habe auch versucht, das SOAPBinding explizit einzustellen:

Exception Details: System.InvalidOperationException: Namespace='com.hrs.soap.hrs' is not supported with rpc\literal SOAP. The wrapper element has to be unqualified.

Source Error: 

Line 15917:        [System.Web.Services.Protocols.SoapDocumentMethod(Use = System.Web.Services.Description.SoapBindingUse.Literal)]
Line 15918:        BLL.HRSService.pingResponse BLL.HRSService.HRSSoapService.ping(BLL.HRSService.pingRequest request) {
Line 15919:            return base.Channel.ping(request);
Line 15920:        }
Line 15921:

OK, jetzt habe ich den SOAP-Bindungsstil geändert, um ihn in meiner lokalen WSDL zu dokumentieren, und die Klassen neu erstellt. Dabei ist ein anderer Fehler aufgetreten:
