调用.NET Web服务时有问题？ [英] Problem when calling .net webservice?

问题描述

我创建了一个样本Android应用程序即调用简单的.NET Web服务，并显示在TextView中，下面是code前景：

i created a sample android app i.e. calling simple .net webservice and displaying in TextView, below are the code prospects:

Web服务code：

web service code:

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
 [System.Web.Script.Services.ScriptService]
public class Service : System.Web.Services.WebService
{
    public Service () {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 
    }

    [WebMethod]
    public string MobileApp(string acNum) 
    {
        return "Account number is"+acNum;
    }

}

Android应用程序code：

android app code:

import java.io.IOException;

import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.view.View;
import android.widget.TabHost;
import android.widget.TextView;

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 AccountDetails extends TabActivity {
    /** Called when the activity is first created. */
    private static final String SOAP_ACTION = "http://tempuri.org/MobileApp";

    private static final String METHOD_NAME = "MobileApp";

    private static final String NAMESPACE = "http://tempuri.org/";
    private static final String URL = "http://localhost:58817/MobService/Service.asmx";
    private TextView tv;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.accountdet);
        tv=(TextView)findViewById(R.id.tView);
ServiceCall();
    }
    public void ServiceCall()
    {
        try{
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        request.addProperty("acNum", "123456");

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet=true;
        envelope.setOutputSoapObject(request);


        androidHttpTransport.call(SOAP_ACTION, envelope);

        SoapObject result = (SoapObject)envelope.getResponse();
        tv.setText(result.toString());

        }       
        catch (final IOException e)

        {

            // TODO Auto-generated catch block

            e.printStackTrace();

        } catch (final XmlPullParserException e)

        {

            // TODO Auto-generated catch block

            e.printStackTrace();

        } catch (final Exception e)

        {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }


    }

此外，我添加以下行到清单文件：

Also i added below lines to the manifest file:

<uses-permission android:name="android.permission.INTERNET" ></uses-permission>
<uses-sdk android:minSdkVersion="7" />

但我没有得到的结果在TextView的，所以任何一个plz帮助我。

But i didn't get the result in TextView, so any one plz help me.

推荐答案

我发现我的错误，这很简单，因为我把用户权限行清单文件中的应用程序标签，但其实，我的投入外使应用程序的标签就是为什么我得到响应。

I found my bug, it is simple, As i put user permission lines in manifest file in the application tag but actually, I've to put outside of the application tag so that's why i'm getting the response.

感谢一个n所有回答我，你的答复还帮助我学习的东西：）
