Żądania SOAP w .NET
Próbujemy używać żądań SOAP do interakcji z interfejsem API rezerwacji przy użyciu programu Visual Studio C #.
Łączymy się z usługą WWW innego API bez problemu, ale ten okazuje się problematyczny.
Dodaliśmy go jako odniesienie do usługi, a Visual Studio wygenerowało wszystkie klasy dla niego i wpisy web.config, aby wszystko wyglądało dobrze.
Jednak kiedy próbujemy wykonać proste żądanie do klienta SOAP Service, otrzymujemy następujący błąd:
Namespace = 'com.hrs.soap.hrs' nie jest obsługiwany przez rpc dosłowne SOAP. Element opakowania musi być niekwalifikowany.
Kod to:
PingRequest pingrequest = new PingRequest();
SoapServiceClient service = new SoapServiceClient();
service.ping(pingrequest);
To, co zostało dodane w pliku 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>
Zgodnie z dokumentacją żądanie powinno wyglądać następująco:
<complexType name="PingRequest">
<complexContent>
<extension base="tns:Request">
<sequence>
<element name="echoData" type="xsd:string"/>
</sequence>
</extension>
</complexContent>
</complexType>

Zainstalowaliśmy Fiddlera i nie ma żadnego żądania XML, które możemy zobaczyć, prawdopodobnie dlatego, że zgłasza wyjątek, zanim cokolwiek zostanie wysłane.
Co dokładnie musimy zmienić w naszej konfiguracji, aby to działało?
AKTUALIZACJA
WSDL: Dostępne [tutaj] [1]
AKTUALIZACJA
Zgodnie z doskonałą radą davidfmatheson skopiowałem lokalnie WSDL i wprowadziłem poprawki zgodnie z sugestią. Nadal otrzymuję ten sam błąd, chociaż prawdopodobnie w innym miejscu:
[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;
}
Linia, która zawodzi, to liniareturn base.Channel.ping (żądanie); z błędemNamespace = 'com.hrs.soap.hrs' nie jest obsługiwany przez rpc dosłowne SOAP. Element opakowania musi być niekwalifikowany.
Próbowałem również jawnie ustawić powiązanie SOAP:
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 teraz zmodyfikowałem styl powiązania SOAP, aby dokumentować w moim lokalnym WSDL i ponownie utworzyć klasy i mam inny błąd:
