Flash, Android 呼叫 ASP.NET WebService

大家好，我是奶綠茶
今天來分享如何使用 Flash 及 Android 呼叫 ASP.NET 的 WebService
WebService 的好處, 就是可以把專案所有要用到的方法, 寫在一隻程式裡, 方便日後管理。
傳接的格式, 都使用 JSON
.net 傳 WebService程式

[WebService(Namespace = "http://milkmidi.com/")] //注意這個 Namespace
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
 [System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {
    private static JavaScriptSerializer serializer = new JavaScriptSerializer();
    public WebService () {
    }
   

    [WebMethod]
    public string getArray() {
        return serializer.Serialize(new string[] { "A", "B", "c" });
    }

    [WebMethod]
    public string getObject() {
        var json = new
        {
            RS = "OK"
        };
        return serializer.Serialize(json);
    }

    /// 

    /// Client 端傳 JSON 格式, Server 端解
    /// 
    
    [WebMethod]
    public string setObject(string json) {
        JsonObject obj = JsonConvert.Import(typeof(JsonObject), json) as JsonObject;
        string name;
        string age;
        try {
            name = obj["name"].ToString();
            age = obj["age"].ToString();
        }
        catch (Exception) {            
            throw;
        }       
        var rs = new
        {
            RS = "OK" ,
            name = name,
            age = age
        };
        return serializer.Serialize(rs);
    }
}

flash端, 使用 FlexSDK 裡的 Webservice 類別
使用方法如下：
 service.要呼叫的方法.send( 參數1, 參數2 );

/**
 * @author milkmidi
 */
package  {  
 import com.adobe.serialization.json.JSON;
 import flash.display.Sprite;
 import mx.rpc.events.FaultEvent;
 import mx.rpc.events.ResultEvent;
 import mx.rpc.soap.LoadEvent;
 import mx.rpc.soap.WebService;
 import mx.utils.ObjectUtil;
 public class MXWebService extends Sprite {  
  public var service:WebService = new WebService();
  public function MXWebService()  {   
   service.wsdl = "http://localhost:61490/webService/WebService.asmx?wsdl";
   service.addEventListener(LoadEvent.LOAD, serviceLoadHandler);
   service.loadWSDL();
   
   //getArray();
   //getObject();   
   setObject(  JSON.encode( { name:"milkmidi", age:"30" } ) );
   
   // 使用 
   // service.要呼叫的方法.send( 參數1, 參數2 );
  }  
  
  private function getArray():void {
   service.getArray.addEventListener(ResultEvent.RESULT, resultHandler);
   service.getArray.addEventListener(FaultEvent.FAULT, faultHandler);
   service.getArray.send();
  }
  private function getObject():void {
   service.getObject.addEventListener(ResultEvent.RESULT, resultHandler);
   service.getObject.addEventListener(FaultEvent.FAULT, faultHandler);
   service.getObject.send();
  }
  private function setObject(json:String):void {
   service.setObject.addEventListener(ResultEvent.RESULT, resultHandler);
   service.setObject.addEventListener(FaultEvent.FAULT, faultHandler);
   service.setObject.send(json);
  }
  
  private function faultHandler(e:FaultEvent):void {
   trace(e);
  }
  
  private function resultHandler(e:ResultEvent):void {
   trace(e);
   trace(ObjectUtil.toString(e.result));
  }
  
  private function serviceLoadHandler(e:LoadEvent):void {
   trace(e);
  }  
  
 }
}

Android 端
參考了這二篇的教學
http://composedcrap.blogspot.com/2009/08/connecting-to-net-web-service-from.html
http://blog.yam.com/wewa85/article/32877801

public class SampleCallWebService extends Activity {
 
 // ASP.NET 端, 宣告的 Namespace
 private static final String NAMESPACE = "http://milkmidi.com/";
 
 //　asmx 路徑
 private static final String URL = "http://localhost:61490/webService/WebService.asmx";

 //要呼叫的方法
 private static final String MemberLogin_SOAP_ACTION = NAMESPACE+"setObject";
 private static final String METHOD_NAME2 = "setObject";

 private Button mBtn;
 private TextView mMsgTxt;

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  mBtn = (Button) findViewById(R.id.btn);  
  mMsgTxt = (TextView) findViewById(R.id.btn);
 
  mBtn.setOnClickListener(new Button.OnClickListener() {
   public void onClick(View v) {
    try {
     mMsgTxt.setText( doSetObject() );
    } catch (JSONException e) {
     e.printStackTrace();
    }
   }

  });
 }
 public String doSetObject() throws JSONException {
  Log.i("[WebService]", "doSetObject");
  String rs = "";
  
  SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME2);
  JSONObject json = new JSONObject();
  json.put("name", "milkmidi");
  json.put("age", "30");
  request.addProperty("json", json.toString());  

  SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
    SoapEnvelope.VER11);
  envelope.dotNet = true;
  envelope.setOutputSoapObject(request);
  HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);  
  try {
   androidHttpTransport.call(MemberLogin_SOAP_ACTION, envelope);  
   SoapPrimitive result = (SoapPrimitive) envelope.getResponse();
   rs = result.toString();
  } catch (Exception e) {
   mMsgTxt.setText(e.toString());
  }
  
  JSONObject rsJson = new JSONObject(rs);  
  return rsJson.getString("name")+","+rsJson.getString("age");

 }
}
