伙计们,我是 android 编程新手,我尝试使用 KSOAP2 将数据发送到 Web 服务。但我无法发送值或获取数据。在调试模式下,它不会显示错误。我正在使用 android 4.1 模拟器。但我找不到任何结果或错误。有人可以纠正我在程序中的错误吗
下面给出了我的java程序,
package com.example.webservice;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;

import android.widget.Toast;
public class WebService extends Activity {
private final String NAMESPACE = "http://tempuri.org/";
private final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl";
private final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
private final String METHOD_NAME = "CelsiusToFahrenheit";
String celsius="";
Button b;
TextView tv;
EditText et;
String res,resultval;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_service);
et=(EditText)findViewById(R.id.editText1);
tv=(TextView)findViewById(R.id.Result);
b=(Button)findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//String result=getFarenheit(et.getText().toString());
//tv.setText(result+"°F");
new service().execute();
}
});
}
private class service extends AsyncTask<Void, Void, String>{
@Override
protected String doInBackground(Void... arg0) {
SoapObject request= new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo celsuiusPI= new PropertyInfo();
celsuiusPI.setName("Celsius");
celsuiusPI.setValue(celsius);
celsuiusPI.setType(String.class);
request.addProperty(celsuiusPI);
SoapSerializationEnvelope envelope=new SoapSerializationEnvelope (SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.implicitTypes = true;
envelope.enc = SoapSerializationEnvelope.ENC2003;
envelope.xsd = SoapEnvelope.XSD;
envelope.xsi = SoapEnvelope.XSI;
envelope.setOutputSoapObject(request);
envelope.setAddAdornments(false);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport=new HttpTransportSE(URL);
try{
androidHttpTransport.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
androidHttpTransport.debug = true;
androidHttpTransport.call(SOAP_ACTION, envelope);
final SoapPrimitive response=(SoapPrimitive)envelope.getResponse();
Toast.makeText(WebService.this, response.toString(), 20).show();
Log.i("WebService output", response.toString());
Object res= response.toString();
resultval=(String) res;
}
catch(Exception e){
e.printStackTrace();
}
return res;
}
protected void onPostExecute(String h){
String result=h;
tv.setText(result+"°F");
}
}
}
上述程序将文本值作为整数发送,并接收摄氏度/华氏度输出。提前感谢程序员,我已经编辑了我的代码,我收到了空值。我怀疑我在代理上,代理服务器是否阻止从 android Emulator 发送/接收数据
