Android 调用WCF实例详解

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

<?xml version="1.0" encoding="utf-8"?>

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));      }    });  }}
