在Android中访问WebService接口

　最近公司有个项目需要从Android平台访问WebService接口，实现向发布的函数传递对象。在网上找了一些资料，发现使用ksoap2可以调用WebService传递对象。
 

需要引入ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar

//WebService的命名空间

static final String namespace = "http://impl.service.suncreate.com";

//服务器发布的url

static final String url = http://10.100.3.41/axis2/services/UploadService;

final String methodName = "upload"; // 函数名

final int sessionID = "111111";  //sessionID

//创建HttpTransportSE对象,通过HttpTransportSE类的构造方法可以指定WebService的url

HttpTransportSE transport = new HttpTransportSE(url);

transport.debug = true; 

//指定WebService的命名空间和函数名

SoapObject soapObject = new SoapObject(namespace, methodName);

//设置调用方法参数的值

soapObject.addProperty("sessionID", sessionID); //sessionID

soapObject.addProperty("data", cds); //cds是需要传递的对象

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);

envelope.bodyOut = transport;

envelope.setOutputSoapObject(soapObject);

//使用call方法调用WebService方法

transport.call(null, envelope);

SoapObject sb = (SoapObject) envelope.bodyIn;

String xmlMessage = sb.toString(); // 获取从服务器端返回的XML字符串
