无法访问tempconvert Web服务 [英] Can't access tempconvert web services

问题描述

我消费tempconvert Web服务，但它不会给任何结果只是显示空白屏幕。

这是不是意味着我的应用程序不能访问Web服务，或者我有一些设置，以便它会连接到URL，我使用kso​​ap2 2.6.5。

这是我的code

 包com.example.webservice2;进口android.os.Bundle;
进口android.widget.TextView;
进口android.app.Activity;
导入org.ksoap2 *。
进口org.ksoap2.serialization.SoapObject;
进口org.ksoap2.serialization.SoapPrimitive;
进口org.ksoap2.serialization.SoapSerializationEnvelope;
进口org.ksoap2.transport.HttpTransportSE;公共类WebService的延伸活动{    私人最终字符串SOAP_ACTION =htt​​p://tempuri.org/CelsiusToFahrenheit;
    私人最终字符串METHOD_NAME =CelsiusToFahrenheit;
    私人最终字符串NAMESPACE =htt​​p://tempuri.org/;
    私人最终字符串URL =htt​​p://www.w3schools.com/webservices/tempconvert.asmx;    TextView的电视;    @覆盖
    公共无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;        电视=（的TextView）findViewById（R.id.tv）;        SoapObject请求=新SoapObject空间（namespace，METHOD_NAME）;
        Request.addProperty（摄氏，32）;        SoapSerializationEnvelope信封=新SoapSerializationEnvelope（
                SoapEnvelope.VER11）;
        envelope.dotNet = TRUE;
        envelope.setOutputSoapObject（请求）;        HttpTransportSE androidHttpTransport =新HttpTransportSE（URL）;        尝试{
            androidHttpTransport.call（SOAP_ACTION，信封）;
            SoapPrimitive响应=（SoapPrimitive）envelope.getResponse（）;            tv.setText（状态：+响应）;        }赶上（例外五）{
            e.printStackTrace（）;
        }
    }
}

import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

public class WebService extends Activity {

    private final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
    private final String METHOD_NAME = "CelsiusToFahrenheit";
    private final String NAMESPACE = "http://tempuri.org/";
    private final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";

        envelope.dotNet = true;
        envelope.setOutputSoapObject(Request);

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();

            tv.setText("status:" + response);

        } catch (Exception e) {
