Überprüfen Sie programmatisch die Version von SOAP (1.1 oder 1.2 oder beide) eine WSDL-Datei unterstützt

Question

Ich benutze C# und ich möchte überprüfen, welche Version von SOAP eine WSDL unterstützt. Wie kann ich das finden?

WSDL 1.1 Datei haben folgende Namespace in es

xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" 

WSDL 1.2-Datei in es

xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/"  

folgende Namespace haben, und wenn eine Datei sowohl Version unterstützt kann es folgende Arten von Inhalten haben in es

<wsdl:binding name="CustServiceSoap" type="tns:CustServiceSoap"> 
    <soap:binding transport="http://schemas.xmlsoap.org/soap/http" /> 
    <wsdl:operation name="GetAllCustomers"> 
     <soap:operation soapAction="http://tempuri.org/GetAllCustomers" style="document" /> 
     <wsdl:input> 
     <soap:body use="literal" /> 
     </wsdl:input> 
     <wsdl:output> 
     <soap:body use="literal" /> 
     </wsdl:output> 
    </wsdl:operation> 
    <wsdl:operation name="GetNCustomers"> 
     <soap:operation soapAction="http://tempuri.org/GetNCustomers" style="document" /> 
     <wsdl:input> 
     <soap:body use="literal" /> 
     </wsdl:input> 
     <wsdl:output> 
     <soap:body use="literal" /> 
     </wsdl:output> 
    </wsdl:operation> 
    <wsdl:operation name="GetRangeOfCustomers"> 
     <soap:operation soapAction="http://tempuri.org/GetRangeOfCustomers" style="document" /> 
     <wsdl:input> 
     <soap:body use="literal" /> 
     </wsdl:input> 
     <wsdl:output> 
     <soap:body use="literal" /> 
     </wsdl:output> 
    </wsdl:operation> 
    </wsdl:binding> 


<wsdl:binding name="CustServiceSoap12" type="tns:CustServiceSoap"> 
    <soap12:binding transport="http://schemas.xmlsoap.org/soap/http" /> 
    <wsdl:operation name="GetAllCustomers"> 
     <soap12:operation soapAction="http://tempuri.org/GetAllCustomers" style="document" /> 
     <wsdl:input> 
     <soap12:body use="literal" /> 
     </wsdl:input> 
     <wsdl:output> 
     <soap12:body use="literal" /> 
     </wsdl:output> 
    </wsdl:operation> 
    <wsdl:operation name="GetNCustomers"> 
     <soap12:operation soapAction="http://tempuri.org/GetNCustomers" style="document" /> 
     <wsdl:input> 
     <soap12:body use="literal" /> 
     </wsdl:input> 
     <wsdl:output> 
     <soap12:body use="literal" /> 
     </wsdl:output> 
    </wsdl:operation> 
    <wsdl:operation name="GetRangeOfCustomers"> 
     <soap12:operation soapAction="http://tempuri.org/GetRangeOfCustomers" style="document" /> 
     <wsdl:input> 
     <soap12:body use="literal" /> 
     </wsdl:input> 
     <wsdl:output> 
     <soap12:body use="literal" /> 
     </wsdl:output> 
    </wsdl:operation> 

Answer 1

public void Foo() 
{ 
    //var uri = new Uri("http://kozhevnikov.com/foo.asmx?WSDL"); 
    //var uri = new Uri("http://kozhevnikov.com/bar.svc?WSDL"); 

    var importer = new WsdlImporter(new MetadataExchangeClient(uri, MetadataExchangeClientMode.HttpGet).GetMetadata()); 
    var version = importer.ImportAllEndpoints().Aggregate(Soap.None, (v, e) => v | Parse(e.Binding.MessageVersion.Envelope)); 

    if (version == Soap.None) 
     Console.WriteLine("Is None."); 
    if (version.HasFlag(Soap.Both)) 
     Console.WriteLine("Has Both."); 

    Console.WriteLine(version); 
} 

private static Soap Parse(EnvelopeVersion version) 
{ 
    if (version == EnvelopeVersion.None) 
     return Soap.None; 
    if (version == EnvelopeVersion.Soap11) 
     return Soap.Soap11; 
    if (version == EnvelopeVersion.Soap12) 
     return Soap.Soap12; 
    throw new NotImplementedException(version.ToString()); 
} 

public enum Soap 
{ 
    None, 
    Soap11, 
    Soap12, 
    Both = Soap11 | Soap12 
}
