一:webService简介
那么什么是webService呢?,它是一种基于SAOP协议的远程调用标准,通过webservice可以将不同操作系统平台,不同语言,不同技术整合到一起。
二:在AdroidManifest.xml中加入权限
<!-- 访问网络的权限 -->
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
三:导入ksoap2包
首先下载KSOAP包:ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar包 复制到工程下的lib文件件里面
然后在android项目:右键->build path(构建路径)->configure build path(添加外部归档)--选择ksoap2
四:编写android可客户端代码
导入包库:
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
函数方法:
try {
final String SERVER_URL = "http://124.205.154.198:8081/Service.asmx";
String nameSpace = "http://tempuri.org/";//命名空间
String methodName = "Sum";//方法名
String soapAction = "http://tempuri.org/Sum";//HelloWorld 命名空间/方法名
//创建SoapObject实例
SoapObject request = new SoapObject(nameSpace, methodName);
request.addProperty("a", "g"); //这个是传递参数的 当然了不要参数就不必写这个了啊
//request.addProperty("passonString", "Rajapandian"); //这个是传递参数的
//生成调用web service方法的soap请求消息
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true; //设置.net web service
envelope.setOutputSoapObject(request);//发送请求
HttpTransportSE androidHttpTransport = new HttpTransportSE(SERVER_URL);
androidHttpTransport.call(soapAction, envelope);
Object result = (Object) envelope.getResponse();
//textView.setText(e.getMessage());
textView.setText(result.toString());
//textView.setText("7");
new AlertDialog.Builder(this).setTitle("Hint").setMessage(result.toString()).setPositiveButton("OK", null).show();
}
catch (Exception e)
{
System.out.println(e.getMessage());
textView.setText(e.getMessage());
new AlertDialog.Builder(this).setTitle("Hint").setMessage(e.getMessage()).setPositiveButton("OK", null).show();
}
五:webService方法
[WebMethod]
public string Sum(string a)
{
string c =a+"hello android";
return c;
}
