How to call a WCF service using ksoap2 on android?
Question
Here is my code
import org.ksoap2.*;
import org.ksoap2.serialization.*;
import org.ksoap2.transport.*;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class ksop2test extends Activity {
/** Called when the activity is first created. */
private static final String METHOD_NAME = "SayHello";
// private static final String METHOD_NAME = "HelloWorld";
private static final String NAMESPACE = "http://tempuri.org";
// private static final String NAMESPACE = "http://tempuri.org";
private static final String URL = "http://192.168.0.2:8080/HelloWCF/Service1.svc";
// private static final String URL = "http://192.168.0.2:8080/webservice1/Service1.asmx";
final String SOAP_ACTION = "http://tempuri.org/IService1/SayHello";
// final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
TextView tv;
StringBuilder sb;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tv = new TextView(this);
sb = new StringBuilder();
call();
tv.setText(sb.toString());
setContentView(tv);
}
public void call() {
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("name", "Qing");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
sb.append(envelope.toString() + "\n");//cannot get the xml request send
SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
//to get the data
String resultData = result.toString();
// 0 is the first object of data
sb.append(resultData + "\n");
} catch (Exception e) {
sb.append("Error:\n" + e.getMessage() + "\n");
}
}
}
I can successfully access .asmx service, but when I try to call a wcf service the virtual machine said : Error: expected:END_TAG{http://schemas.xmlsoap.org/soap/envelope/}Body(position:END_TAGhttp://schemas.xmlsoap.org/soap/envelope/}s:Fault>@1:712 in java.io.InputStreamReader@43ba6798
How to print what the request send?
Here is the wcf wsdl:
<wsdl:definitions name="Service1" targetNamespace="http://tempuri.org/">
<wsdl:types>
<xsd:schema targetNamespace="http://tempuri.org/Imports">
<xsd:import schemaLocation="http://para-bj.para.local:8080/HelloWCF/Service1.svc?xsd=xsd0" namespace="http://tempuri.org/"/>
<xsd:import schemaLocation="http://para-bj.para.local:8080/HelloWCF/Service1.svc?xsd=xsd1" namespace="http://schemas.microsoft.com/2003/10/Serialization/"/>
</xsd:schema>
</wsdl:types>
<wsdl:message name="IService1_SayHello_InputMessage">
<wsdl:part name="parameters" element="tns:SayHello"/>
</wsdl:message>
<wsdl:message name="IService1_SayHello_OutputMessage">
<wsdl:part name="parameters" element="tns:SayHelloResponse"/>
</wsdl:message>
<wsdl:portType name="IService1">
<wsdl:operation name="SayHello">
<wsdl:input wsaw:Action="http://tempuri.org/IService1/SayHello" message="tns:IService1_SayHello_InputMessage"/>
<wsdl:output wsaw:Action="http://tempuri.org/IService1/SayHelloResponse" message="tns:IService1_SayHello_OutputMessage"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="BasicHttpBinding_IService1" type="tns:IService1">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="SayHello">
<soap:operation soapAction="http://tempuri.org/IService1/SayHello" style="document"/>
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="Service1">
<wsdl:port name="BasicHttpBinding_IService1" binding="tns:BasicHttpBinding_IService1">
<soap:address location="http://para-bj.para.local:8080/HelloWCF/Service1.svc"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
It uses <xsd:schema>
in tag <wsdl:types>
and the asmx uses <s:schema>
in tag <wsdl:types>
what's the difference?
Solution
finally I got it to work because the namespace missed a "/" in the end ,
following is my code
package cn.qing.ksop2test;
import java.io.Writer;
import org.ksoap2.*;
import org.ksoap2.serialization.*;
import org.ksoap2.transport.*;
import org.xmlpull.v1.XmlSerializer;
import android.app.Activity;
import android.os.Bundle;
import android.util.Xml;
import android.widget.TextView;
public class ksop2test extends Activity {
/** Called when the activity is first created. */
private static final String METHOD_NAME = "HelloWorldRequest";
// private static final String METHOD_NAME = "HelloWorld";
private static final String NAMESPACE = "http://tempuri.org/";
// private static final String NAMESPACE = "http://tempuri.org";
private static final String URL = "http://192.168.0.2:8080/HelloWCF/Service1.svc";
// private static final String URL = "http://192.168.0.2:8080/webservice1 /Service1.asmx";
final String SOAP_ACTION = "http://tempuri.org/IService1/HelloWorld";
// final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
TextView tv;
StringBuilder sb;
private XmlSerializer writer;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tv = new TextView(this);
sb = new StringBuilder();
call();
tv.setText(sb.toString());
setContentView(tv);
}
public void call() {
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("Name", "Qing");
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();
// 0 is the first object of data
sb.append(resultData + "\n");
} catch (Exception e) {
sb.append("Error:\n" + e.getMessage() + "\n");
}
}
}
OTHER TIPS
I'm using
private static final String SOAP_ACTION = "http://tempuri.org/IContact/GetContactCount";
private static final String METHOD_NAME = "GetContactCount";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://xxx.xxx.com/Contacts/ContactsService.Contacts.svc";
So maybe the problem is in your SOAP action.
Also is the spelling on your method name correct ie AuthenticatdUser?
In "theory" wcf with basic http binding and asmx should work the same.
It could be something to do with how your WCF service is configured.
We get a similar problem if we configure TransferMode Streamed on the client and Buffered on the server. Although not sure if this is relevant in your case.
Thanks Qing for your answer it's really help full for calling WCF service
I would like to add this rectification for getting simple and complex output from web service after setting outputSoapObject into envelope,please correct me if i'm wrong
envelope.setOutputSoapObject(requestSoapObject);
// if its dotnet web service then make it true
if (isDotNetWebService)
envelope.dotNet = true;
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(NAMESPACE + methodName, envelope);
if (useBodyIn) // use bodyIn if service method returns string/int
// etc
{
/* Gives output from webservice */
responseSoapObject = (SoapObject) envelope.bodyIn;
} else // use getResponse() if service method returns objects or
// array
{
/* Gives output from webservice */
responseSoapObject = (SoapObject) envelope.getResponse();
}
