如何在Android中解析SOAP WebServices XML数据？

标签： android web-services soap xml-parsing

我希望在Android肥皂网络服务中将输入请求作为XML发送，最后我希望在Xml中显示响应。我可以在Android中使用那些肥皂网络服务。

 package com.venkattt.pack;

import java.net.SocketException;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;
import org.ksoap2.transport.HttpTransportSE;

import android.app.Activity;
import android.os.Bundle;

public class SoapWebservicesExampleActivity extends Activity {
    /** Called when the activity is first created. */
      final String NAMESPACE = "urn:sap-com:document:sap:soap:functions:mc-style";
     final String URL = "http://**********:8000/sap/bc/srt/wsdl/srvc_14DAE9C8D79F1EE196F1FC6C6518A345/wsdl11/allinone/ws_policy/document?sap-client=800&sap-user=*******&sap-password=*******";
      final String METHOD_NAME = "Z_GET_CUST_GEN";
     final String SOAP_ACTION = "urn:sap-com:document:sap:soap:functions:mc-style/Z_GET_CUST_GEN";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); // set up
            request.addProperty("Input", "1460");
            request.addProperty("Langu", "d");
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12); // put all required data into a soap
            envelope.dotNet = false;
            envelope.setOutputSoapObject(request);
            HttpTransportSE httpTransport = new HttpTransportSE(URL);
            httpTransport.debug = true;

            try {

                 httpTransport.call(SOAP_ACTION, envelope);
                 Object result = (Object) envelope.getResponse();

                 System.out.println("theeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee result"+result);

                }
            catch(SocketException ex){
                    ex.printStackTrace();
                } catch (Exception e) {
                   e.printStackTrace();
                }
        }
    }

我编写了使用Android服务器的代码，但我没有得到xml数据？

嗨，这可能对你http://www.codeproject.com/Articles/112381/Step-by-Step-Method-to-Access-Webservice-from-Andr

有用

答案 1 :(得分：0)

为此你必须下载两个文件，

您还需要，

  • 公地HttpClient的-3.0.1.jar
  • ksoap2-机器人组装-2.5.4-罐与 - dependencies.jar

然后在类call()的{​​{1}}方法中，您可以将xml响应分配给您定义的String，并可以进一步访问它。

下面是相同的伪代码，

AndroidHttpTransport

然后responseDump = new String(buf); unescape(responseDump); your_string = responseDump; 将获得完整的xml响应。

       HttpPost httppost = new HttpPost("http://192.168.1.103/test/index1.php");
        //httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost); 
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
        Log.e("log_tag", "connection success ");
     //convert response to string

        BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) 
        {
            sb.append(line + "\n");

        }
        is.close();
        result=sb.toString();
        //Log.e("",""+result);

使用DOM Parser或SAX Parser它会更好......这个链接肯定会对你有用：

当您致电HttpTransport.responseDump

时，您将能够获得结果

这是我实施的方式

public String GetNewTransaction_service(String login_id,String Password_id)
{



    String SOAP_ACTION = "http://www.webserviceX.NET/GetWeather";
    String METHOD_NAME = "GetWeather";
    String NAMESPACE  = "http://www.webserviceX.NET";
    String SOAP_ADDRESS = "http://www.webservicex.com/globalweather.asmx";

    SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME);
    request.addProperty("login",login_id);
    request.addProperty("pwd",Password_id);

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

    HttpTransportSE httpTransaport = new HttpTransportSE(SOAP_ADDRESS);
    httpTransaport.debug = true;

    String response = null;


    try
    {
        httpTransaport.call(SOAP_ACTION,envelope);
        response = httpTransaport.responseDump;
    } catch (XmlPullParserException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return  response;
}
