在移动设备中，使用XML传输可能会消耗更多的资源，Android不提供任何组件来直接调用WCF，但是我们可以相对简单地通过第三方包调用rest WCF服务，那么Android 调用WCF实例详解，大家清楚吗？爱站技术频道小编告诉你。

Android 调用WCF实例
1. 构建服务端程序
using System.ServiceModel;
namespace yournamespace
{
[ServiceContract(Name = "HelloService", Namespace = "http://www.master.haku")]
public interface IHello
{
[OperationContract]
string SayHello();
}
}
namespace YourNameSpace
{
public class YourService
{
public string SayHello(string words)
{
return "Hello " + words;
}
}
}
2. 构建IIS网站宿主
YourService.svc
%@ServiceHost Debug="true" Service="YourNameSpace.YourService"%>
Web.config
3. 寄宿服务
把网站发布到web服务器, 指定网站虚拟目录指向该目录
如果你能够访问http://你的IP:端口/虚拟目录/服务.svc
那么,恭喜你,你的服务端成功了!
4. 使用ksoap2调用WCF
去ksoap2官网
http://code.google.com/p/ksoap2-android/ 下载最新jar
5. 在Eclipse中新建一个Java项目,测试你的服务
新建一个接口, 用于专门读取WCF返回的SoapObject对象
ISoapService
package junit.soap.wcf;
import org.ksoap2.serialization.SoapObject;
public interface ISoapService {
SoapObject LoadResult();
}
HelloService
package junit.soap.wcf;
import java.io.IOException;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParserException;
public class HelloService implements ISoapService {
private static final String NameSpace = "http://www.master.haku";
private static final String URL = "http://你的服务器/虚拟目录/你的服务.svc";
private static final String SOAP_ACTION = "http://www.master.haku/你的服务/SayHello";
private static final String MethodName = "SayHello";
private String words;
public HelloService(String words) {
this.words = words;
}
public SoapObject LoadResult() {
SoapObject soapObject = new SoapObject(NameSpace, MethodName);
soapObject.addProperty("words", words);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); // 版本
envelope.bodyOut = soapObject;
envelope.dotNet = true;
envelope.setOutputSoapObject(soapObject);
HttpTransportSE trans = new HttpTransportSE(URL);
trans.debug = true; // 使用调试功能
try {
trans.call(SOAP_ACTION, envelope);
System.out.println("Call Successful!");
} catch (IOException e) {
System.out.println("IOException");
e.printStackTrace();
} catch (XmlPullParserException e) {
System.out.println("XmlPullParserException");
e.printStackTrace();
}
SoapObject result = (SoapObject) envelope.bodyIn;
return result;
}
}
测试程序
package junit.soap.wcf;
import org.ksoap2.serialization.SoapObject;
public class HelloWcfTest {
public static void main(String[] args) {
HelloService service = new HelloService("Master HaKu");
SoapObject result = service.LoadResult();
System.out.println("WCF返回的数据是：" + result.getProperty(0));
}
}
经过测试成功
运行结果:
Hello Master HaKu
6. Android客户端测试
package david.android.wcf;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
import org.ksoap2.serialization.SoapObject;
public class AndroidWcfDemoActivity extends Activity {
private Button mButton1;
private TextView text;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mButton1 = (Button) findViewById(R.id.myButton1);
text = (TextView) this.findViewById(R.id.show);
mButton1.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
HelloService service = new HelloService("Master HaKu");
SoapObject result = service.LoadResult();
text.setText("WCF返回的数据是：" + result.getProperty(0));
}
});
}
}
7. 最后运行结果
Android 调用WCF实例详解，大家了解的如何了呢？其实我们在这个步骤在项目开发中是很关键的，一定要学习透彻，才能够让自己更加顺利的推进项目的进行。
