我试图将.net SOAP Web服务与ksoap2 lib一起使用。 http://www.vimeo.com/9633556中的示例显示了如何进行纠正。在该示例的代码下方。一切都应该正常工作!但是我得到强制关闭错误!
这是我的代码:
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class SoapTest2Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView TV ;
TV=(TextView)findViewById(R.id.textView1);
TV.setText("Hi");
String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
String METHOD_NAME = "CelsiusToFahrenheit";
String NAMESPACE = "http://tempuri.org/";
String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
System.setProperty("http.keepAlive", "false");
SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
Request.addProperty("Celsius", "32");
SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
soapEnvelope.dotNet = true;
soapEnvelope.setOutputSoapObject(Request);
HttpTransportSE httpTransport = new HttpTransportSE(URL);
try
{
httpTransport.call(SOAP_ACTION, soapEnvelope);
SoapPrimitive resultString = (SoapPrimitive)soapEnvelope.getResponse();
TV.setText(resultString.toString());
}
catch (Exception e) {
e.printStackTrace();
}
}
}
请帮忙
最佳答案
您的代码是正确的,但只能在Android 2中使用。如果使用v4 ICS / JB,则必须使用AsyncTask。
package com.example.wscall3;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends Activity {
private String TAG ="Vik";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
AsyncCallWS task = new AsyncCallWS();
task.execute();
}
private class AsyncCallWS extends AsyncTask<Void, Void, Void> {
@Override
protected Void doInBackground(Void... params) {
Log.i(TAG, "doInBackground");
calculate();
return null;
}
@Override
protected void onPostExecute(Void result) {
Log.i(TAG, "onPostExecute");
}
@Override
protected void onPreExecute() {
Log.i(TAG, "onPreExecute");
}
@Override
protected void onProgressUpdate(Void... values) {
Log.i(TAG, "onProgressUpdate");
}
}
public void calculate()
{
String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
String METHOD_NAME = "CelsiusToFahrenheit";
String NAMESPACE = "http://tempuri.org/";
String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
try {
SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
Request.addProperty("Celsius", "32");
SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
soapEnvelope.dotNet = true;
soapEnvelope.setOutputSoapObject(Request);
HttpTransportSE transport= new HttpTransportSE(URL);
transport.call(SOAP_ACTION, soapEnvelope);
SoapPrimitive resultString = (SoapPrimitive)soapEnvelope.getResponse();
Log.i(TAG, "Result Celsius: " + resultString);
}
catch(Exception ex) {
Log.e(TAG, "Error: " + ex.getMessage());
}
SOAP_ACTION = "http://tempuri.org/FahrenheitToCelsius";
METHOD_NAME = "FahrenheitToCelsius";
try {
SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
Request.addProperty("Fahrenheit", "100");
SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
soapEnvelope.dotNet = true;
soapEnvelope.setOutputSoapObject(Request);
HttpTransportSE transport= new HttpTransportSE(URL);
transport.call(SOAP_ACTION, soapEnvelope);
SoapPrimitive resultString = (SoapPrimitive)soapEnvelope.getResponse();
Log.i(TAG, "Result Fahrenheit: " + resultString);
}
catch(Exception ex) {
Log.e(TAG, "Error: " + ex.getMessage());
}
}
}
我的AndroidManifest.xml是:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.wscall3"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="7"
android:targetSdkVersion="16" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.wscall3.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
