Android调用WCF | 易学教程

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"?>
<configuration>
  <system.serviceModel>
    <serviceHostingEnvironment>
      <serviceActivations >
        <add relativeAddress="YourService.svc" service="YourNameSpace.YourService"/>
      </serviceActivations >
    </serviceHostingEnvironment >

    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBindingCfg" closeTimeout="00:01:00"
            openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
            bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
            maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647"
            messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
            allowCookies="false">
          <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>

    <services>
      <service name="YourNameSpace.YourService" behaviorConfiguration="ServiceBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:59173/YourService"/>
          </baseAddresses>
        </host>
        <endpoint binding="basicHttpBinding" contract="YourNameSpace.你的服务契约接口">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
  <system.web>
    <compilation debug="true" />
  </system.web>
</configuration>

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
