Question

我从WCF web service调用Android application时遇到问题。如果我拨打以下网址"http://10.0.2.2:80/WebService/WebServiceImpl.svc"，我会收到回复"200 OK"，但当我尝试在服务"http://10.0.2.2:80/WebService/WebServiceImpl.svc/Test"内调用该功能时，我会收到回复"400 Bad request"。

有人可以帮忙吗？

namespace WebService
{
    public class WebServiceImpl : IWebServiceImpl
    {
        #region IRestServiceImpl Members
        public string Test()
        {
            return "Test pass";
        }

        #endregion
    }
}

namespace WebService
{
    [ServiceContract]
    public interface IWebServiceImpl
    {
     [OperationContract]
        [WebInvoke(
            Method = "GET")]
        string Test();
    }
}

Android活动：

    public void onClick(View v)
    {
        // TODO Auto-generated method stub
        HttpClient  client = new DefaultHttpClient();
        String SERVER_HOST="10.0.2.2";
        int SERVER_PORT = 80;
        String URL = "http://10.0.2.2:80/WebService/WebServiceImpl.svc/Test";
        HttpHost target = new HttpHost(SERVER_HOST, SERVER_PORT, "http");
        HttpGet request = new HttpGet(URL);
        try
        {
            HttpResponse response = client.execute(target,request);
            HttpEntity entity = response.getEntity();
            MessageBox(response.getStatusLine().toString());
        }
        catch(Exception e)
        {
            MessageBox("excepton");
            MessageBox(e.toString());
        }
    }

    public void MessageBox(String message){
        Toast.makeText(this,message,Toast.LENGTH_LONG).show();
    }

我使用“SoapObject”来解决这个问题

代码的一部分：

public static final String NAMESPACE = "http://tempuri.org/";
public static final String URL = "http://10.0.2.2:80/MyFirstPublishedWebService/WebServiceImpl.svc?wsdl";  
public static final String SOAP_ACTION = "http://tempuri.org/IWebServiceImpl/Login";
public static final String METHOD_NAME = "Login";

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = 
    new SoapSerializationEnvelope(SoapEnvelope.VER11); 

envelope .dotNet = true;

envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

try {
    androidHttpTransport.call(SOAP_ACTION, envelope);
}
catch (Exception e) {

}

亚历克斯，谢谢你的回答！

首先在浏览器中测试此网址。如果您遇到同样的问题，请在清单中为您的服务启用Web访问。

如果您的手机可以通过ip 10.0.2.2进行二次检查。
