android调用webservice接口应用实例【转】

public String userLogin(String userName, String pwd) {
String url = "http://xx.xx.com/services/User";
String nameSpace = "http://xx.xx.com";
String SOAP_ACTION  = "http:/xx.xx.com/services/User/login";
String method = "login";
String result = "";
SoapObject request = new SoapObject(nameSpace, method);

request.addProperty("nickname", userName);
request.addProperty("password", pwd);

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut = request;
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE ht = new HttpTransportSE(url);
try {
ht.call(SOAP_ACTION, envelope);
Object object = envelope.getResponse();
result = object.toString();
} catch (Exception e) {
e.printStackTrace();
}
return result;
}

一，需要注意的是SOAP_ACTION可以有可无。

二，有时候会报java.lang.ClassCastException: org.ksoap2.serialization.SoapPrimitive错误，解决方法如下：

以下内容来自：http://blog.csdn.net/whybiang/article/details/6533051

在服务器端返回值是String类型的数值的时候使用SoapObject soapObject = (SoapObject) envelope.getResponse();和 SoapObject result = (SoapObject)envelope.bodyIn;这两种方法来接受值都会报出

java.lang.ClassCastException: org.ksoap2.serialization.SoapPrimitive这样的错误。

我们可以使用 Object object = envelope.getResponse();就可以解决这种错误。

如果服务器返回值的类型是byte[] 的时候，使用Object object = envelope.getResponse();和SoapObject result = (SoapObject)envelope.bodyIn;

都不会发生错误现象，但是在使用Object object = envelope.getResponse();取回来的值在使用base64进行解码和编码的时候会报出错误。

如果使用SoapObject result = (SoapObject)envelope.bodyIn;就可以完整的将byte[]进行解码和编码

，byte[] ops = Base64.decode(result.getProperty(0).toString());至于在用SoapObject soapObject = (SoapObject)

envelope.getResponse();来接受byte[]返回值,由于时间关系我没有进行测试
