简单介绍

本篇博客是Android调用WCF服务的简单实例。

实例

本例以简单的一个创建通知的WCF接口为例讲述Android与WCF的交互。
首先可使用WcfTestClient测试下WCF接口的CreateNotice方法，可参照上篇Java调用WCF的博客。
新建WCFService调用WCF的工具类如下

package com.carlos.wcf;

import android.os.Handler;
import android.os.Message;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParserException;

import java.io.IOException;
import java.util.Iterator;
import java.util.Map;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

/**

 */
public class WCFService {
    public static final String WCF_URL="";//引号类改为自己的
    public static final String NAMESPACE="";//引号类改为自己的
    public static final String SOAP="";//引号类改为自己的
    private static final ExecutorService executorService= Executors.newFixedThreadPool(3);

    /**
     * 调用WCF方法
     * @param methodName
     * @param properties
     * @param wcfServiceCallBack
     */
    public static void callWCFService(final String methodName,Map properties, final WCFServiceCallBack
                                 wcfServiceCallBack){
        // 创建HttpTransportSE对象，传递WCFService服务器地址
        final HttpTransportSE httpTransportSE=new HttpTransportSE(WCF_URL);
        SoapObject soapObject=new SoapObject(NAMESPACE,methodName);
        if(properties!=null){
            for(Iterator<Map.Entry<String,Object>> it=properties.entrySet().iterator();it.hasNext();){
                Map.Entry<String,Object> entry=it.next();
                soapObject.addProperty(entry.getKey(),entry.getValue());
            }
        }

        // 实例化SoapSerializationEnvelope，传入WebService的SOAP协议的版本号
        final SoapSerializationEnvelope soapEnvelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
        soapEnvelope.bodyOut=soapObject;
        // 设置是否调用的是.Net开发的WCFService
        soapEnvelope.setOutputSoapObject(soapObject);
        soapEnvelope.dotNet=true;
        httpTransportSE.debug=true;

        // 用于子线程与主线程通信的Handler
        final Handler mHandler=new Handler(){
            @Override
            public void handleMessage(Message msg) {
                super.handleMessage(msg);
                // 将返回值回调到callBack的参数中
                wcfServiceCallBack.callBack((SoapObject) msg.obj);
            }
        };
        // 开启线程去访问WCFService
        executorService.submit(new Runnable() {
            @Override
            public void run() {
                SoapObject resultSoapObject=null;
                try {
                    httpTransportSE.call(SOAP+methodName,soapEnvelope);
                    if(soapEnvelope.getResponse()!=null){
                        resultSoapObject= (SoapObject) soapEnvelope.bodyIn;
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (XmlPullParserException e) {
                    e.printStackTrace();
                }finally {
                    // 将获取的消息利用Handler发送到主线程
                    mHandler.sendMessage(mHandler.obtainMessage(0,resultSoapObject));
                }
            }
        });
    }

    /**
     * 回调接口
     */
    public interface WCFServiceCallBack{
        public void callBack(SoapObject result);
    }
}

MainActivity类里面调用该方法打印出返回的WCF结果

package com.carlos.wcf;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import org.ksoap2.serialization.SoapObject;

import java.util.HashMap;

public class MainActivity extends AppCompatActivity {

    private Button b_get_WCFResult;
    private final static String TAG="WCFResult";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        b_get_WCFResult= (Button) findViewById(R.id.b_get_WCFResult);

        b_get_WCFResult.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getWCFResult();
            }
        });

    }

    private void getWCFResult(){
        HashMap<String,Object> map=new HashMap<>();
        map.put("title", "提醒");
        map.put("content", "晚上写篇博客");
        WCFService.callWCFService("CreateNotice", map, new WCFService.WCFServiceCallBack() {
            @Override
            public void callBack(SoapObject result) {
                if(result!=null){
                    Toast.makeText(MainActivity.this,result.toString(),Toast.LENGTH_SHORT).show();
                    Log.i(TAG, result.toString());

                    SoapObject soapObject=(SoapObject)result.getProperty("result");
                    Log.i(TAG,soapObject.toString());
                    if(soapObject.toString().equals("anyType{}")){
                        Log.i(TAG,"没有结果");
                    }else{
                        for(int i=0;i<soapObject.getPropertyCount();i++){
                            Log.i("WCFResult",soapObject.getProperty(i).toString());
                        }
                    }

                }
            }
        });
    }
}

点击获取WCF结果的按钮后控制台输出的结果
