3. 寄宿服务
把网站发布到web服务器, 指定网站虚拟目录指向该目录
如果你能够访问http://你的IP:端口/虚拟目录/服务.svc
那么,恭喜你,你的服务端成功了!
4. 使用ksoap2调用WCF
去ksoap2官网
http://code.google.com/p/ksoap2-android/ 下载最新jar
5. 在Eclipse中新建一个Java项目,测试你的服务
新建一个接口, 用于专门读取WCF返回的SoapObject对象
ISoapService

public class HelloService implements ISoapService {
private static final String MethodName = "SayHello";
private String words;
public HelloService(String words) {
this.words = words;
}
public SoapObject LoadResult() {
SoapObject soapObject = new SoapObject(NameSpace, MethodName);
soapObject.addProperty("words", words);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); // 版本
envelope.bodyOut = soapObject;
envelope.dotNet = true;
envelope.setOutputSoapObject(soapObject);
HttpTransportSE trans = new HttpTransportSE(URL);
trans.debug = true; // 使用调试功能
try {
trans.call(SOAP_ACTION, envelope);
System.out.println("Call Successful!");
} catch (IOException e) {
System.out.println("IOException");
e.printStackTrace();
} catch (XmlPullParserException e) {
System.out.println("XmlPullParserException");

public static void main(String[] args) {
HelloService service = new HelloService("Master HaKu");
SoapObject result = service.LoadResult();
System.out.println("WCF返回的数据是：" + result.getProperty(0));
}
} |
经过测试成功
运行结果:
Hello Master HaKu

7. 最后运行结果
安卓（Android）开发：利用ksoap2调用webservice服务，并自动生成客户端代理类代码
安卓调用Webservice和Java稍有不同，利用的是ksoap2这个jar包。之前这个jar包是发布在googlecode上面的目前项目已经移动到了github.io，我这里贴上的github官方网站，我也不知道这个github.io和github.com是不是一回事。我们可以在以下页面看到项目的总览：http://simpligility.github.io/ksoap2-android/index.html。
1.下载ksoap2jar包
ksoap2项目的源码在这里，有兴趣的可以弄下来研究哦：
2.在Android Studio中进行配置
这一步简单，先放到lib文件夹下，然后再lib上点击右键，选择ADD AS LIB就可以了哦
3.利用网上的服务，自动生成ksoap2可用的webservice的客户端代理类
打开http://www.wsdl2code.com/pages/Home.aspx页面，在页面的右边填入你的webService的访问地址，然后选择生成的方式，我选的是Android Using kSoap2.如果你的webservice还没有发布，也可以直接上传其wsdl文件。
点击submit，此时要求登录，如果没有账号就注册一个，然后登陆，稍等一会这个工具就会为我们自动生成Webservice客户端代理类的代码了，点击下载
当然，自动生成的没有与jar运行环境啊什么的，可能使用的时候有些问题，至少包命名就得改成你自己的，所以，我们再简单的修改一下这些代码就可以直接使用了，省去了我们手动写客户端代理类的麻烦，是不是很方便啊。
