Consuming WCF service in android

android, wcf

Solution

Your first attempt is pretty close. There are just two fixes needed:

String METHOD_NAME = "Dummy";
String NAMESPACE = "http://tempuri.org/";
String URL = "http://tyty.cloudapp.net/Service1.svc";
String SOAP_ACTION = "http://tempuri.org/IPMPService/Dummy";

String res = "";
try {
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
    androidHttpTransport.call(SOAP_ACTION, envelope);
    SoapPrimitive result = (SoapPrimitive) envelope.getResponse();
    // to get the data
    String resultData = result.toString();
    res = resultData;
    // 0 is the first object of data
} catch (Exception e) {
    res = e.getMessage();
}

The first one is the method name: it just `Dummy` (instead of `DummyRequest`). The second is the SOAP action: it's `http://tempuri.org/IPMPService/Dummy`.

Both can be derived from the WSDL. Your operation is defined as:

<wsdl:operation name="Dummy">
    <wsdl:input wsaw:Action="http://tempuri.org/IPMPService/Dummy" message="tns:IPMPService_Dummy_InputMessage"/>
    <wsdl:output wsaw:Action="http://tempuri.org/IPMPService/DummyResponse" message="tns:IPMPService_Dummy_OutputMessage"/>
</wsdl:operation>

If you then look at the `IPMPService_Dummy_InputMessage` message type, the element is called `Dummy`:

<wsdl:message name="IPMPService_Dummy_InputMessage">
    <wsdl:part name="parameters" element="tns:Dummy"/>
</wsdl:message>

And the SOAP action is found here:

<wsdl:operation name="Dummy">
    <soap:operation soapAction="http://tempuri.org/IPMPService/Dummy" style="document"/>
    ...

Problem

I've created this service (using WCF, Azure): ``` [ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)] public class Service1 : IPMPService { public int Dummy() { return 0; } } ``` Where IPMPService is: ``` [ServiceContract] public interface IPMPService { [WebGet()] [OperationContract] int Dummy(); } ``` And attempted to consume it in my android app: 1st attempt: ``` String METHOD_NAME = "DummyRequest"; String NAMESPACE = "http://tempuri.org/"; String URL = "http://tyty.cloudapp.net/Service1.svc"; String SOAP_ACTION = "http://tyty.cloudapp.net/Service1.svc/Dummy"; String res = ""; try { SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet = true; envelope.setOutputSoapObject(request); HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); androidHttpTransport.call(SOAP_ACTION, envelope); SoapPrimitive result = (SoapPrimitive) envelope.getResponse(); // to get the data String resultData = result.toString(); res = resultData; // 0 is the first object of data } catch (Exception e) { res = e.getMessage(); } ``` result: SoapFault - faultcode: 'a:ActionNotSupported' faultstring: 'The message with Action 'http://tyty.cloudapp.net/Service1.svc/Dummy' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).' faultactor: 'null' detail: null 2nd attempt (taken from here): ``` String SERVER_HOST = "http://tyty.cloudapp.net"; int SERVER_PORT = 8080; String URL1 = "/Service1.svc/Dummy"; String keywords = null; HttpEntity entity = null; HttpClient client = new DefaultHttpClient(); HttpGet get = new HttpGet(URL1); try { HttpResponse response = client.execute(target, get); entity = response.getEntity(); keywords = EntityUtils.toString(entity); } catch (Exception e) { e.printStackTrace(); } finally { if (entity != null) try { entity.consumeContent(); } catch (IOException e) { } } ``` Result: java.net.UnknownHostException: Unable to resolve host "http://tyty.cloudapp.net": No address associated with hostname I've also created a (working) client in c#, here is its App.config: ``` <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_IPMPService" 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="http://tyty.cloudapp.net/Service1.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IPMPService" contract="IPMPService" name="BasicHttpBinding_IPMPService" /> </client> </system.serviceModel> </configuration> ``` As mentioned, both attempts in Android failed. Can anyone please tell me what I'm doing wrong, and how to do it right? Thanks.
