android調用webservice接口應用實例

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可以有可無。

二，有時候會報java.lang.ClassCastException: org.ksoap2.serialization.SoapPrimitive錯誤，解決方法如下：

以下內容來自：http://blog.csdn.net/whybiang/article/details/6533051

在服務器端返回值是String類型的數值的時候使用SoapObject soapObject = (SoapObject) envelope.getResponse();和 SoapObject result = (SoapObject)envelope.bodyIn;這兩種方法來接受值都會報出 

java.lang.ClassCastException: org.ksoap2.serialization.SoapPrimitive這樣的錯誤。

我們可以使用 Object object = envelope.getResponse();就可以解決這種錯誤。 

 如果服務器返回值的類型是byte[] 的時候，使用Object object = envelope.getResponse();和SoapObject result = (SoapObject)envelope.bodyIn;

都不會發生錯誤現象，但是在使用Object object = envelope.getResponse();取回來的值在使用base64進行解碼和編碼的時候會報出錯誤。

如果使用SoapObject result = (SoapObject)envelope.bodyIn;就可以完整的將byte[]進行解碼和編碼

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

envelope.getResponse();來接受byte[]返回值,由於時間關系我沒有進行測試
