Android 从java代码调用.net web服务时获取java.io.IoException

我的代码：

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

import android.util.Log;
import android.widget.Toast;

public class CallSoap {
    public final String SOAP_ACTION = "http://tempuri.org/SendMessage";

    public final String OPERATION_NAME = "SendMessage";

    public final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";

    public final String SOAP_ADDRESS = "http://omega-solutions.in/ExpertsApp.asmx";

    public CallSoap() {
    }

    public String Call(String deviceid, String msg) {
        SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
                OPERATION_NAME);
        PropertyInfo pi = new PropertyInfo();
        pi.setName("deviceid");
        pi.setValue(deviceid);
        pi.setType(String.class);
        request.addProperty(pi);
        pi = new PropertyInfo();
        pi.setName("msg");
        pi.setValue(msg);
        pi.setType(String.class);
        request.addProperty(pi);

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

        envelope.setOutputSoapObject(request);

        HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
        Object response = null;
        try {



            httpTransport.call(SOAP_ACTION, envelope);






            response = envelope.getResponse();
            Log.e("after", "" + "after");
        } catch (Exception exception) {

            Log.e("before", "" + "before" + exception.toString());
            response = exception.toString();
        }
        return response.toString();
    }
}

当我运行此代码时

httpTransport.call(SOAP_ACTION, envelope);

在上述代码行之后，我收到了java.io.ioException。

请检查您的web服务的web方法是否已关闭连接。因为我也遇到了相同的问题，但在关闭web服务中的web方法的sql连接后，它已被重新访问。。。。一切都好

发布你的日志，需要更多信息。我只得到java.io.ioException什么都没有。我不确定这个异常。顺便说一下，你会得到很多其他的异常，比如networkOnMainThread。。。您应该使用asynctask进行网络操作。我建议您更改整个代码。请尝试此操作以获取参考
