Android调用.net ASMX Service

折腾了两天时间，终于把这个搞定了。在这期间也学习了很多东西。万事开头难啊。

1. 新建一个安卓项目，下载ksoap2-android-assembly-2.4-jar-with-dependencies.jar（138m）.并加载到工程libraries中，然后还需要在Order and Export中选中这个包。具体来说就是：选中工程->Java Build Path->选中标签Order and Export->选中没有找到的class的jar包或者包含的工程->点击OK。如果不做这一步，会出现莫名异常，调用永远不会成功。这个东西耽误了我很长时间。后来问了蝈蝈大神才知道是怎么回事。

2. 由于android默认是禁用soket所以在开始之前需要修改AndroidManifest.xml。添加：<uses-permission android:name="android.permission.INTERNET" />

3.我自己把调用的地方封装了一下，以后可以直接使用：

package gs.utils;

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

public class AsmxUtil
{
private String SOAP_ACTION = "";
private String NAMESPACE = "http://tempuri.org/";
private String METHOD_NAME = "";
private String ServiceURL = "";
SoapObject request =null;

public AsmxUtil(String serviceurl, String methodName)
{
ServiceURL = serviceurl;
METHOD_NAME = methodName;
SOAP_ACTION = NAMESPACE + METHOD_NAME;
request = new SoapObject(NAMESPACE, METHOD_NAME);
}

public void AddProperty(String name, Object v)
{
request.addProperty(name, v);
}

public String Call() throws Exception
{
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut = request;
envelope.dotNet=true;
HttpTransportSE ht = new HttpTransportSE(ServiceURL);
ht.debug = true;
try {
ht.call(SOAP_ACTION, envelope);
if (envelope.getResponse() != null)
{
String msg = envelope.getResponse().toString();
return msg;
}
else
{
return "";
}
}
catch (Exception e) {
throw new Exception(e.getMessage());
}
}
}

4.使用方法

AsmxUtil au = new AsmxUtil("http://192.168.1.105:92/MyWebService.asmx", "DoubleNum");
au.AddProperty("a", 111);
String xst = null;
try {
xst = au.Call();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

xst就是最后的结果
